Fermented skincare: how to assess a fashionable claim

Fermented skincare claims often lack robust scientific evidence, so approach them with a critical eye. ## What is fermented skincare? Fermented skincare involves using ingredients that have undergone fermentation, a process where microorganisms break down substances to create new compounds. Proponents claim this enhances nutrient absorption and boosts skin health. ## What are the claimed benefits? Common claims include improved hydration, brighter complexion, and reduced inflammation. However, these claims are often based on limited studies or anecdotal evidence. ## How to assess the claims ### Look for peer-reviewed studies Check if the product’s claims are supported by independent, peer-reviewed research. Avoid relying solely on brand marketing. ### Examine ingredient lists Focus on active ingredients and their concentrations. Fermented ingredients should be clearly listed, and their benefits should be scientifically validated. ### Patch test new products Before fully incorporating a fermented skincare product into your routine, perform a patch test to check for adverse reactions. ## Practical takeaway Today, critically evaluate fermented skincare claims by researching peer-reviewed studies and examining ingredient lists. Always patch test new products to ensure they suit your skin.
