The article discusses the latest trends in skincare, highlighting ingredients such as seaweed, cannabidiol, and reindeer fat, which are increasingly being used in beauty products. It raises questions about the efficacy of these ingredients and whether they pose any risks to humans or the environment. To gain a professional perspective, the author consults chemist Sanna Hokkanen from LUT University, who has authored a book on cosmetic ingredients.

According to Hokkanen, seaweed extracts, particularly those derived from macroalgae, are praised for their moisturizing and protective properties. These extracts contain polysaccharides, polyphenols, and minerals, which have been shown to offer hydrating and antioxidative effects. Specifically, polysaccharides in seaweed can attract moisture to the skin, thereby softening its surface and improving elasticity. The article emphasizes the science behind these claims and encourages readers to consider the evidence before incorporating such products into their skincare routines.

Furthermore, the article delves into the environmental and health implications of using these ingredients, which are gaining popularity in the cosmetic industry. As consumers become more aware of the substances they apply to their bodies and the impact of those ingredients on the environment, the discussion informs them about potential benefits and harms, allowing for more informed decisions in their skincare choices.
