So I have these:
Paula's Choice Glycolic 8% - I was using this before but stopped. After a few months, I'm now thinking of using again
The Ordinary (TO) Niacinamide
TO Vitamin C 23% - I have been using for almost a week
TO Buffet - tried once
TO Moisturizing Factor - tried 2-3x; seems like just a moisturizer so prob can be used anytime?
TO Hyaluronic Acid
Tretinoin 0.05% which I plan to start.
I know Vit C and Niacinamide
