Algae Extract Skincare Benefits:
Anti-Aging
Antioxidant
Brightening
Soothing

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. 1

One of the essential amino acids present in algae extract is Mycosporine-Like Amino Acid. This amino acid, among other constituents, contains 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. 2

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 deterring signs of aging. 2 All together, the benefits of algae extract make it a favorable ingredient to include in a wide range of skincare products.
