Bran, yes...true RetinA is dermatologist prescribed. Many products may carry small amounts in a lesser strength and sold over-the-counter.

If she's never used it she should start with the lower strength. .05 or .025. LOTS of moisturizer. wink SUNSCREEN!

I love all of the pharmacies. Maho, the one near ZeeBest and Frenchy Ludo's, etc.
