ABSTRACT

Thalassotherapy is a term that emerged at the beginning of the 18th century, originating in the Greek “thalasso” and “therapia”. A rather wide range of marine algae enter in the packs used in thalassotherapy, and algal flours or algal salts are sold for use in home bath therapy. Phymatolithon calcareum is a calcareous marine alga whose thallus is used in the treatment of decalcification, osteoporosis, painful joints, chronic tiredness, painful stages of rheumatism, gingivitis, stomach pains, and in anti-acid cures. The marine brown seaweeds play a significant role of the bioactive compounds production, and they are the only organisms on earth producing phlorotannins, which are polyphenols exhibiting important biological activities. In general, cosmeceuticals are often used in the field of dermatology to improve skin tone/whitening, increase skin radiance, decrease the appearance of skin wrinkling, and provide antiaging benefits.
