Hi all! I would like some help finding the best brush for my very sensitive skin. I’ve never had this problem before, but since I started using Retin-A for my acne, the brush I use for my foundation / setting powder is really stinging my face. This is a Sephora brand brush that I bought a long time ago. I’m up for an upgrade and looking for a foundation / setting / finishing powder brush that is SUPER DUPER soft so my skin doesn’t hurt. Ideas? Thank you in advance for your help!
