Why don’t they add the active ingredients after formulas have cooled down? Many companies do, but you can’t be sure that’s always the case. The solution: Two “raw beauty” lines have pledged never to heat their formulas high enough to compromise the efficacy of the ingredients. Products from the Body Deli (thebodydeli.com), an organic line made from superfoods, and Raw Essentials (rawessentials.com), a new skin-care line created by model Carol Alt, are not heated above 115ºF, the highest temperature that exfoliating and wrinkle-reducing enzymes can tolerate. (The norm, by comparison, is 150 to 175ºF.) No matter the brand, be sure to store all creams and serums that contain retinols, vitamins, and enzymes in a cool place—as in, far away from your steamy shower.
