I am77 and have been using prescription Retin-A on my face since my late 30's. It peeled and looked awful for 5 to 6 months until my skin got used to it. Then my skin looked like new soft and smooth skin. Over my nightly Retin-A I have been using Paula's Choice products. I have an allergy to salicylic acid so I can't use her best product, her BHA serum, or anything else that contains salicylic aci joeybayou · paulaschoice.com

I will use and buy this serum until the day I don’t care anymore. But right now I care a lot. I am loving the dewy glow it gives me. Right off the bat. Also—total plump of the cheeks and all the pretty parts of the face that could use a plump or boost. I mean this stuff is incredible. I have gotten so many compliments on my skin and I feel like it’s thanks to this miracle serum. Don’t get my wrong warmsunnyd · sephora.com
