Cosmetic Corn Starch and Why it Should be Avoided

If you are a user of pressed powder, or powder blush here is some information you should consider, corn starch and rice powder should not be in your products. People who are prone to acne should not use powders that contain both ingredients mainly for the following reasons. Starch is derived from corn and sometimes used as an absorbent in cosmetics instead of talc (which is safe to use). However, when cornstarch becomes moist, it can promote fungal and bacterial growth. Rice powder is also an absorbent substance that is sometimes included in products rather than talc. It can cause allergic reactions and, because it is a food derivative (as opposed to a mineral derivative like talc), it can support bacterial growth in pores. Most importantly, if you are acne-prone avoid starch altogether, your face will sweat during the day and trap the starch within the pores. Although its difficult to find suitable products Neutrogena's pressed powder is safe and L'oreal's Softening Blush, both contain talc instead of cornstrarch.

  1. This has not been true in my case. I use it for sweat proned areas purely and have finally been able to avoid fungal or heat rash problems. And I love to stay quite active. I have been using it on my face for over a year and have not had any acne problems, other than the ocassional blemish.
