The beneficial properties of algae for the skin have been known for centuries, but to see their application in industrial production we had to wait until France at the beginning of the 20th century. It was there that the first laboratories specialized in the research and development of cosmetic products began.
The first products made from algae were soaps, shaving creams, shampoos, dyes, lipsticks, tonics, make-up, foams and a wide variety of bath products. Their success was almost immediate and their demand grew. They were beneficial because of their high content of trace elements, mineral salts, vitamins and amino acids that help to maintain the good appearance of the skin, as they are directly assimilated by the skin cells.
The most common forms of application are gels, masks, emulsions, shampoos, lotions and creams, and among its many uses are toning, moisturizing, rejuvenating and anti-cellulite treatments.
Nowadays, in the composition of cosmetic products, not only algae are used, but also products derived from them, such as agar-agar. It is one of the most common elements due to its suspensive, emulsifying, stabilizing and gelling properties that avoid incorporating fat to the product, a very important characteristic when developing products for the skin. In addition, it is non-toxic and non-irritating, which is essential for people with skin problems.
