Algae Extract for Skin


Marine algae extracts have been used in alternative cosmetics for skin-related diseases since ancient times. Today, marine algae extracts have been extensively used in skin care products due its rich bioactive compounds.

Algae extract is formed from the four major seaweed classes: red algae, brown algae, blue-green algae, and green algae. Each class contains molecules that promote skin benefits such as: omega 3 fatty acids, amino acids, and vitamins A, B, C, and E.

One of the essential amino acids present in algae extract is Mycosporine, which is an amino acid. This amino acid contains strong antioxidant properties that help to effectively neutralize free radicals present in the environment. By lowering the amount of oxidative stress found in the skin, algae extract may also work to reinforce barrier function and provide soothing properties that can help alleviate dry skin.

In addition, studies show topical application of algae extract containing secondary metabolites, such as phlorotannins, can potentially function as a brightening agent. For this reason, cosmetic formulas often infuse algae extract as a way to promote skin radiance.

Lastly, with its antioxidant activity and high concentrations of polyphenols, extract from algae species like fucoidan may be a therapeutic agent for fighting signs of aging.

Altogether, the benefits of algae extract for skin make it a favorable ingredient to include in a wide range of skin care products.

Marine algae have gained tremendous attention in cosmeceuticals. They are one of the richest marine resources considered safe and possessed negligible cytotoxicity effects on humans. Marine algae are rich in bioactive substances that have shown to exhibit strong benefits to the skin, particularly in overcoming rashes, pigmentation, aging, and cancer.

Algae Extract for Skin and Beauty

In a study published in 2013 in the International Journal of Biological Macromolecules, researchers looked at the potential benefits of five different types of algae extract for skin care, to absorb and retain moisture, something that could obviously be useful in skin care.

They examined how much water the algae—which included three different types of green algae, one type of red algae, and one type of brown algae—would absorb when dry and how well it would then retain it over time. Their results showed that the brown algae extract, which had the lowest molecular weight, did the best. In fact, the results were even better than hyaluronic acid, a common skin-care ingredient that’s known for its powerful humectant effect.

Blue green algae, which already has a fair amount of wellness hype around it, has also performed well in skin care studies. For a study published in Clinical Pharmacology & Biopharmaceutics in 2015, researchers had 40 female subjects apply a gel cream to their faces twice a day for 28 days. They were sorted into two age groups (18-39 and 40-60) and two treatment groups (half got a gel cream that actually contained the blue green algae extract while the other have got a control cream).

After the 28-day study period, the researchers found that those who received the algae cream did show more water retention in the outer layer of the skin compared to those who got the control cream. Thanks to algae extract, skin may benefit significantly to it’s hydration benefits.

Top 4 Benefits of Algae Extract for the Skin

Algae Extract and Hydration

As mentioned earlier, one of the key benefits of algae extract for the skin is its ability to hydrate. Algae extract is rich in polysaccharides, which act as natural humectants to draw moisture into the skin. This makes it an excellent ingredient for those with dry or dehydrated skin.

In addition to its hydrating properties, algae extract also helps to strengthen the skin barrier. The skin barrier is responsible for keeping moisture in and harmful pollutants out. By strengthening the skin barrier, algae extract helps to keep the skin hydrated and healthy.

Algae Extract and Anti-Aging Properties

Another benefit of algae extract for the skin is its anti-aging properties. Algae extract is rich in antioxidants, which help to protect the skin from free radical damage. Free radicals are unstable molecules that can cause damage to the skin, leading to premature aging.

Algae extract also helps to stimulate collagen production in the skin. Collagen is a protein that is responsible for keeping the skin firm and plump. As we age, collagen production naturally decreases, leading to wrinkles and sagging skin. By stimulating collagen production, algae extract helps to keep the skin looking youthful and radiant.

Algae Extract and Skin Brightening

Algae extract has also been found to have skin-brightening properties. Algae extract contains a compound called fucoxanthin, which has been found to inhibit the production of melanin. Melanin is the pigment that gives our skin its color, but too much melanin can lead to dark spots and uneven skin tone.

By inhibiting the production of melanin, algae extract helps to brighten the skin and improve overall skin tone. Additionally, algae extract contains vitamin C, which is a powerful antioxidant that helps to brighten the skin and reduce the appearance of dark spots.

Algae Extract and Acne Prevention

Finally, algae extract has been found to be effective in preventing acne. Algae extract contains compounds that have antibacterial properties, which help to kill the bacteria that can cause acne. Additionally, algae extract has anti-inflammatory properties, which can help to reduce the redness and swelling associated with acne.

Our Hyaluronic & Multi Peptide Serum include algae extract and is a fantastic way to rejuvenate skin naturally.


There is a lot of evidence that shows algae is a huge benefit to your skin, in a variety of ways. As science continues it's work and completion of studies, we can learn more about this wonderfully natural, healthy ingredient.
