Skincare you buy from the drug stores & department store or your neighborhood beauty rep (even some of the pricier ones) are not monitored at the same FDA and dermatology standards. First, medical grade skin care is required to be tested by the FDA for 10 years and 99% pure, cosmetic grade is not required to be FDA tested and is only held at 70% purity. Second, the active ingredients in medical grade skin care is always higher in percentage, quality and efficacy claims than that of cosmetic grade skin care. For this reason, medical grade skin care is only available through professionals.
As a result, cosmetic grade products typically don’t deliver the desired effect in a timely manner, if at all. Bottom line – They’re often a waste of money. To sum it up, the cosmetics products aren’t regulated the same way that medical products are, so it’s up to the manufacturer to make sure products are safe and consistent.
