What's the real story where Red Algae are harvested?

rosh hanikra marine reserve israel red algae harvesting form the sea

Red algae seaweed is growing in the sea in many places around the world.

You can find seaweed in shallow waters from the tide line to the depth of 500 feet ( 150 m). 

In Josepa Skincare, the Red Algae was originally harvested from a beautiful marine natural reserve, in the north of Israel,  many years ago. The marine natural reserve is adjacent to the beach which is considered the cleanest beach in Israel. You can see the Rosh Hanikra Marine Nature Reserve in the photo above. Isn't it beautiful? 

Since than, we grow the Red Algae in detached clean ponds on the beach. The sea water to the ponds is coming from the heart of the marine nature reserve, and we constantly draw fresh sea water.

Open your speaker and listen to the sound. Look how clean are our Red Algae.  

Why Red Algae is so special?

The reason that the red algae can live is such depth is that they can absorb blue light, and the red light cannot reach into deep water because of its long wavelength. The reason that for the red color of Red Algae is the presence of a pigment called phycoerythrin, which absorb the blue light and reflect the red light. 

Due to the harsh environment in the sea, the Red Algae seaweed developed to be very resilient and resistant to currents and surroundings, so they will not be destroyed. 

Our Red Algae Gel (Red Alage Hydrogel)  is different from Red Algae extract

Most Red Algae are grown in the sea and attracts parasites, small crabs and snails. After harvesting they must get rid of these parasites. Than they process it in high temperature to kill the parasites. Together with the parasites they harm the vitamins and the amino-acids. 

After that they make an extract out of what is left, and they get the Red Algae Extract. Many skincare and cosmetics companies are using the Red Algae Extract, as they found that it is very beneficial for skincare. 

In Josepa Skincare, we grow our Red Algae in detached ponds on the beach

Our Red Algae have no parasites and is very clean.

Look how clean is our Red Algae:

Josepa Skincare clean red algae for skincare routine

We process the Red Algae at a temperatures that preserves all the vitamins and amino-acids and make the whole Red Algae into a gel.
Currently, no one else in the world have the technology of making the red algae gel as we have.
In tests, we found that we have about 10 times more amino acids comparing to a sample red algae extract.


We use the Red Algae Hydrogel in all Josepa Skincare line of products.  

Now you can figure out yourself how effective are our products with the red algae gel.

The best part - why Red Algae is great for your skin

Red Algae is an active ingredient for skin health. Red Algae is a rich source amino-acids, vitamins, minerals. It is a natural source for polysaccharides which proved to be effective to replenish the skin's natural water reservoir, help to enhance the skin's natural barrier and increase the moisture retention capabilities of the skin. 

Skin Natural Antioxidant

Why do you need antioxidants for your skin? Your skin is exposed to the environment, which is not so friendly. There are the sun rays and if you add to it the pollution that we have today, you will find that your skin is under constant stress by the environment, which can impact the skin's natural barrier that keeps the moisture.  The free radials and pollution in the air, wear down the skin natural integrity and make it vulnerable to visible damages and wrinkles.

Skincare products rich with antioxidants may help your skin to retain its natural barrier functionality and defend from the free radicals.

Red Algae is rich with polysaccharides, peptides and carotenoids which can contribute to its antioxidants properties. 

Red Algae is rich with antioxidants, and this can help with the the look and appearance of your skin. 

Skin Sun protection

Just to make it clear, you need to use SPF skincare products, even when you are using red algae based products.

Our skin is very sensitive to sun rays which damage it and is one of the reasons for aging of the skin.  

Red Algae is rich with amino acids, among them you can find amino acids that are effective antioxidants. The antioxidants are absorbing the solar light and as such protects from UV sun rays. 

Red Algae is effective in supporting the SPF functions along with sunscreen product, to ensure that your skin stays fresh and healthy.  

Aid in skin moisturizing - Can stabilize minerals that aid in skin moisturizing

Skin Hydration and Skin moisture retaining

Red algae is very beneficial for hydrating your skin and nourishing it. Red Algae texture make it very effective in storing water. The interesting fact is that when applied to skincare, this texture actually draws water to the surface of your skin.

This plumping activity makes it useful for minimizing the look of fine lines and also creases, as well as can also boost moisture to avoid over-dry skin that can lead to acne. An excellent  humectant will certainly also aid balance your skin, after using acid therapies or laser therapies that cause irritations. 

High vitamin content - Can lead to healthier young looking skin

Skin Brightening

There are many reasons that people want to brighten their skin. Whether its from dark spots that developed as people age , sun exposure, or they just want to brighten the color of their skin. Dark spots also can be developed from scars, acne marks and post-inflamtory hyper-pigmentation. 

Red algae consists of significant levels of vitamin C: a vital component for rejuvenating the skin tone. The Vitamin C antioxidant is ideal not just for scavenging skin-damaging  free-radicals, yet for brightening and stabilizing unequal skin tone and complexion.

The way Vitamin C is brighting that skin is by inhibiting tyrosinase. Tyrosinase is  an enzyme that promote melanin production in the skin which is causing darkening in specific patches of the skin in reaction to sunlight damages or to dis-colorization. It is found to fade dark areas without influencing the rest of your skin. If your skin has hyper-pigmentation from sun damage or acne marks, a red-algae-infused skincare products might do the work for you.


Combats free radicals

Free radicals are fighting your skin by damaging cells, and cause illness and aging. 

The way to combat free radicals is by protecting with antioxidants, which prevents the oxidation of the skin cells. 

Researchers found that Red Algae has the ability to generate natural antioxidants that prevents damage to the red algae by harsh environment and sun light.

Open your pores

The combination of oil and also dead skin cells blocking your pores will certainly cause blackheads and also outbreaks, so gently getting rid of these toxins from your skin is important. Furthermore, the Red Algae antibacterial and antioxidant properties are perfect for cleaning as well as healing skin that is swollen or affected with acne.

Red algae are an outstanding remedy to help open up these locations and also launch the contaminants triggering inflammation as well as breakouts if you are tired of clogged and also dark pores. This family members of algae works to clean, hydrate, and refresh your skin, excavating deep right into the pores to remove excess oil and also clean dead skin cells.

Refresh your skin

As we grow and our skin ages, the collagen stores start to decrease, triggering the skin to develop creases, create fine lines, and also lose its elasticity. The all-natural aging process together with the destructive toxins of  free radicals. from the environment, can truly do a hit on your skin.

Red algae are an effective aid to impede the decrease of collagen stores, allowing you to keep more younger, plump skin.

Repair your skin

Red Algae enables your skin to be extra tight and experience repair from the influence of aspects like sunlight damages or free radicals. In functioning to lower the appearance of wrinkles and fine lines , your skin eventually experiences healing and gets the nutrition it needs to combat creases and wrinkles in the future.

Whether your skin is starting to crease due to the all-natural aging process or has retained damage from excessive time spent in the sun, the Red Algae properties are there to aid. The algae contain concentrated amounts of lipids, vitamins, minerals, and also innate healthy proteins that carefully soak into your skin.

Increase skin elasticity

Red algae is rich in polysaccharides, that assist retain moisture and to hydrate your skin. 

Red Algae has demonstrated anti-aging properties by inhibiting enzymes that break down collagen in the skin.

Red Algae helps to improve skin elasticity and its natural protective barrier and reduce the appearance of fine lines and wrinkles, by hydrating and nourishing the skin cellsRough skin becomes smoother and it visibly refines the skin’s texture appearance.

Healing properties

Red Algae bears a significant amount of water, in addition to considerable quantities of vitamins, anti-oxidants, as well as minerals. This water material indicates that you can make use of products including algae on your skin as a normal cleanser, to relieve your pores and very carefully tide out oil, dead skin, as well as various other toxins that are collected throughout the day.

The anti-oxidants in red algae are efficient in combating harmful free radicals as well as other toxins. They are additionally a powerful agent to reduce unwanted inflammation in the skin, lessen the intensity of skin disease. Red Algae top qualities of Vitamin C and E guard your skin against damages, UV rays and also promote additional collagen production to maintain your skin naturally hydrated in all times.

Reduces inflammation

Inflammation is a good response of the body that signals that something not good is happening. Inflammation is a complex physical response which involves activation of the body immune system. It happens after a physical injury or intrusion by pathogenic bacteria, infections or tumor cells into the body.  Inflammation and swelling are vital to identify and also ruin the invading pathogens and viruses  in intense disease states.

Red Algae consist of a variety of anti-inflammatory bioactive substances such as omega-3 polyunsaturated fats as well as chlorophyll.

What science is saying about Red Algae

On reproduction in red algae: further research needed at the molecular level

Pilar García-Jiménez and Rafael R. Robaina

Multicellular red algae (Rhodophyta) have some of the most complex life cycles known in living organisms. Economically valuable seaweeds, such as phycocolloid producers, have a triphasic (gametophyte, carposporophyte, and tetrasporophyte) life cycle, not to mention the intricate alternation of generations in the edible “sushi-alga” nori. It is a well-known fact that reproductive processes are controlled by one or more abiotic factor(s), including day length, light quality, temperature, and nutrients. Likewise, endogenous chemical factors such as plant growth regulators have been reported to affect reproductive events in some red seaweeds. Still, in the genomic era and given the high throughput techniques at our disposal, our knowledge about the endogenous molecular machinery lags far behind that of higher plants. Any potential effective control of the reproductive process will entail revisiting most of these results and facts to answer basic biological questions as yet unresolved. Recent results have shed light on the involvement of several genes in red alga reproductive events. In addition, a working species characterized by a simple filamentous architecture, easy cultivation, and accessible genomes may also facilitate our task.

Insights into the red algae and eukaryotic evolution from the genome of Porphyra umbilicalis (Bangiophyceae, Rhodophyta)

Fossil evidence shows that red algae (Rhodophyta) are one of the most ancient multicellular lineages. Their ecological, evolutionary, and commercial importance notwithstanding, few red algal nuclear genomes have been sequenced. Our analyses of the Porphyra umbilicalis genome provide insights into how this macrophyte thrives in the stressful intertidal zone and into the basis for its nutritional value as human food. Many of the novel traits (e.g., cytoskeletal organization, calcium signaling pathways) we find encoded in the Porphyra genome are extended to other red algal genomes, and our unexpected findings offer a potential explanation for why the red algae are constrained to small stature relative to other multicellular lineages.

Depth Studies on Photosynthesis of the Red Algae

R. H. Tschudy , American Journal of Botany, Vol. 21, No. 9 (Nov., 1934), pp. 546-556

1. Most photosynthesis takes place in both the red and brown algae in less than 10 meters of water. 2. It is clearly evident, however, that the red algae are able to utilize the light that penetrates to a depth of 22.5-25 meters, while the brown algae seem unable to synthesize carbohydrates in more than 15 meters of water. 3. Maximum photosynthesis takes place not at the surface, but usually at a depth of about 5 meters. This is probably due to the fact that the intensity of the light at the surface is too great for maximum synthesis. On cloudy days, or when the water is choppy, maximum photosynthesis is at the surface. 4. The view that the pigmentation of the red algae is correlated with the fact that they grow at a sea depth where the sun rays that penetrate are complementary to red-i.e., green-seems untenable in view of the fact that some red algae grow at the surface or very near to it, where the rays that penetrate are not complementary to red. 5. It is probable that the red algae are able to utilize the shorter wave lengths of light in much the same manner as do "shade plants." Most workers lay stress on the fact that in the absorption spectrum of chlorophyll the most intense absorption takes place in the region of the red rays. More attention should be directed to the absorption band in the blue-violet end of the spectrum.

Macroalgae-derived ingredients for cosmetic industry

Filipa B. Pimentel , Rita C. Alves  , Francisca Rodrigues and M. Beatriz P. P. Oliveira 

​Aging is a natural and progressive declining physiological process that is influenced
by multifactorial aspects and affects individuals’ health in very different ways. The skin is one
of the major organs in which aging is more evident, as it progressively loses some of its natural
functions. With the new societal paradigms regarding youth and beauty have emerged new concerns
about appearance, encouraging millions of consumers to use cosmetic/personal care products as
part of their daily routine. Hence, cosmetics have become a global and highly competitive market
in a constant state of evolution. This industry is highly committed to finding natural sources of
functional/bioactive-rich compounds, preferably from sustainable and cheap raw materials, to deliver
innovative products and solutions that meet consumers’ expectations. Macroalgae are an excellent
example of a natural resource that can fit these requirements. The incorporation of macroalgae-derived
ingredients in cosmetics has been growing, as more and more scientific evidence reports their
skin health-promoting effects. This review provides an overview on the possible applications of
macroalgae as active ingredients for the cosmetic field, highlighting the main compounds responsible
for their bioactivity on skin.

Mycosporine-like Amino Acids from Red Algae Protect against Premature Skin-Aging

Schmid, Daniel & Schürch, Cornelia & Zülli, Fred. (2006).

Skin ages in two ways: one is slow and normal and the other is the rapid aging induced by sunlight. UV-screening compounds to reduce damage caused by ultraviolet (UV) radiation are almost ubiquitous in nature.The most active natural UV-absorbing substances are the mycosporine-like amino acids (MAA) which are produced by certain algae, corals and zooplankton.The peak absorption of MAA is in the UVA range and their absorption coefficients are similar to those of synthetic sunscreens. Two in vitro studies demonstrated a DNA-protecting effect and the viability enhancing properties of MAA from the red alga Porphyra umbilicalis.A human study showed that a cream containing MAA efficiently protects the skin against UVA-induced lipid oxidation.

Exploring the potential of using algae in cosmetics

The applications of microalgae in cosmetic products have recently received more attention in the treatment of skin problems, such as aging, tanning and pigment disorders. There are also potential uses in the areas of anti-aging, skin-whitening, and pigmentation reduction products. While algae species have already been used in some cosmetic formulations, such as moisturizing and thickening agents, algae remain largely untapped as an asset in this industry due to an apparent lack of utility as a primary active ingredient. This review article focuses on integrating studies on algae pertinent to skin health and beauty, with the purpose of identifying serviceable algae functions in practical cosmetic uses.

Beneficial Effects of Marine Algal Compounds in Cosmeceuticals

Thomas NV, Kim SK.

The name "cosmeceuticals" is derived from "cosmetics and pharmaceuticals", indicating that a specific product contains active ingredients. Marine algae have gained much importance in cosmeceutical product development due to their rich bioactive compounds. In the present review, marine algal compounds (phlorotannins, sulfated polysaccharides and tyrosinase inhibitors) have been discussed toward cosmeceutical application. In addition, atopic dermatitis and the possible role of matrix metalloproteinase (MMP) in skin-related diseases have been explored extensively for cosmeceutical products. The proper development of marine algae compounds will be helpful in cosmeceutical product development and in the development of the cosmeceutical industry.

Marine algal natural products with anti-oxidative, anti-inflammatory, and anti-cancer properties

Jin-Ching Lee, Ming-Feng Hou, Hurng-Wern Huang, Fang-Rong Chang, Chi-Chen Yeh, Jen-Yang Tang,corresponding author and Hsueh-Wei Chang

For their various bioactivities, biomaterials derived from marine algae are important ingredients in many products, such as cosmetics and drugs for treating cancer and other diseases. This mini-review comprehensively compares the bioactivities and biological functions of biomaterials from red, green, brown, and blue-green algae. The anti-oxidative effects and bioactivities of several different crude extracts of algae have been evaluated both in vitro and in vivo. Natural products derived from marine algae protect cells by modulating the effects of oxidative stress. Because oxidative stress plays important roles in inflammatory reactions and in carcinogenesis, marine algal natural products have potential for use in anti-cancer and anti-inflammatory drugs.

Red Seaweed Gracilaria as Multi Products Source

Matteo Francavilla ,Massimo Franchi ,Massimo Monteleone and Carmela Caroppo 

In recent years seaweeds have increasingly attracted interest in the search for new drugs and have been shown to be a primary source of bioactive natural compounds and biomaterials. In the present investigation, the biochemical composition of the red seaweed Gracilaria gracilis, collected seasonally in the Lesina Lagoon (Southern Adriatic Sea, Lesina, Italy), was assayed by means of advanced analytical techniques, such as gas-chromatography coupled with mass spectrometry and spectrophotometric tests. In particular, analysis of lipids, fatty acids, sterols, proteins, phycobiliproteins and carbohydrates as well as phenolic content, antioxidant and radical scavenging activity were performed. In winter extracts of G. gracilis, a high content of R-phycoerythrin together with other valuable products such as arachidonic acid (PUFA ω-6), proteins and carbohydrates was observed. High antioxidant and radical scavenging activities were also detected in summer extracts of the seaweed together with a high content of total phenols. In conclusion, this study points out the possibility of using Gracilaria gracilis as a multi products source for biotechnological, nutraceutical and pharmaceutical applications even although more investigations are required for separating, purifying and characterizing these bioactive compounds.

Chemical characterization and antioxidant activity of sulfated polysaccharide from the red seaweed Gracilaria birdiae

 Bartolomeu W.S. Souza, Miguel A. Cerqueira, Ana I. Bourbon, Ana C. Pinheiro, Joana T. Martins,
José A. Teixeira, Manuel A. Coimbra, António A. Vicente

Hydrocolloids from seaweeds have interesting functional properties, such as antioxidant activity and
gelling ability. A polysaccharide was isolated by aqueous extraction at 90 C from the red seaweed
Gracilaria birdiae (Gb), with a yield of 27.2% of the seaweed dry weight. The sulfate content of the
polysaccharide was 8.4% and the main sugars present were galactose (65.4 mol%), 3, 6-anhydrogalactose (25.1 mol%) and 6-O-methylgalactose (9.2 mol%). Gel permeation chromatography showed that Gb polysaccharide is a heterogeneous system, with molar mass at the main peak of 3.7 10 to the power of 5 g mol  to the power of -1 and a shoulder of 2.6 10 to the power of g mol  to the power of -1 . The sulfated polysaccharide of Gb characterized by FTIR exhibits the characteristic bands of agarocolloids (at 1375 and 770 cm  to the power of -1). The rheological behavior of Gb sulfated polysaccharide exhibits a gel-like behavior close to the one observed in commercial agar. The antioxidant properties of Gb sulfated polysaccharide were evaluated by measuring DPPH freeradical scavenging effect, showing that this polysaccharide has a moderate effect in inhibiting the formation of those radicals.

Antiviral Potential of Algae Polysaccharides Isolated from Marine Sources: A Review

Azin Ahmadi, Soheil Zorofchian Moghadamtousi, Sazaly Abubakar and Keivan Zandi

From food to fertilizer, algal derived products are largely employed in assorted industries, including agricultural, biomedical, food, and pharmaceutical industries. Among different chemical compositions isolated from algae, polysaccharides are the most well-established compounds, which were subjected to a variety of studies due to extensive bioactivities. Over the past few decades, the promising results for antiviral potential of algae-derived polysaccharides have advocated them as inordinate candidates for pharmaceutical research. Numerous studies have isolated various algal polysaccharides possessing antiviral activities, including carrageenan, alginate, fucan, laminaran, and naviculan. In addition, different mechanisms of action have been reported for these polysaccharides, such as inhibiting the binding or internalization of virus into the host cells or suppressing DNA replication and protein synthesis. This review strives for compiling previous antiviral studies of algae-derived polysaccharides and their mechanism of action towards their development as natural antiviral agents for future investigations.
