If you’re not using a retinol, you need to start now and you need to start with the @kiehl’s Retinol Skin-Renewal Daily Micro-Dose serum. I grew up with difficult skin but retinol has transformed it to the point that people compliment me on it!? Me? It tackles practically every skin concern—texture, lines, brightness, even blemishes. This serum is gentle enough for daily use, even for beginners, and 100% of users (!) showed reduced wrinkles in 12 weeks #kiehlsretinolforall
