The Food and Drug Administration (FDA) divides skin care products into two separate categories: Cosmetic & pharmaceutical. Pharmaceutical products undergo rigorous testing that can go on for more than 10 yrs and cost millions of dollars. Pharmaceutical grade products are only available through a licensed professional. These products not only contain a higher percentage of active ingredients, but higher quality of each ingredient. According to the FDA, pharmaceutical grade products are required to be 99% pure, where cosmetic grade products are only required to be 70% pure. Active ingredients are those that can make a change in your skin such as (reducing wrinkles, pigmentation, alleviate acne, etc.).
