Here's a report from dermatologists about hormones and health and skin:
Although cosmetics and cosmeceuticals are tested for safety, testing to determine whether beneficial ingredients actually live up to a manufacturer's claims is not mandatory. In general, vitamins, herbs, oils, and botanical extracts may be used in cosmeceuticals, but the manufacturer may not claim that these products penetrate beyond the skin's surface layers or that they have druglike or therapeutic effects. For cosmetic labels, all ingredients are listed together and the active ingredients are not noted.
"When considering a cosmeceutical product, itīs important to read the label and determine whatīs in the product," Dr. Berson said. "Look for products that reference clinical trials or show actual before and after photos. Also, donīt be fooled into thinking that a more expensive product from a high-end department store will be better than a cheaper one from the drug store."
Dr. Berson cautioned that some cosmeceuticals make claims that they do not back up with clinical trials. "No cream or lotion can do what a prescription medication or dermatological procedures like botulinim toxin, fillers or laser/light treatments can," Dr. Berson said. "Cosmeceuticals can be combined with dermatological treatments, but they do not replace them. If you have concerns about your skinīs appearance and are not sure what to use, itīs best to consult a dermatologist before purchasing a cosmeceutical."
