Really good alternative option for mandelic acid… Just contains citric acid so cannot use while on tretinoin

Pretty comparable to the Paula‘s Choice peptide options. PC have more ceramides/peptides… Check closer to the date of purchase, but I think it will come down to price and urgency/access to the product

Contains Tranexamic acid and Azelaic acid

Looks like like a really valid alternative option to the ordinary niacinamide serum

More hydrating than the booster but that’s about the only difference

Good alternative Tranexamic acid serum, but contains glycolic acid so cannot use while on tretinoin

Good alternative niacinamide, but contains citric acid so cannot use while on tretinoin.

Also contains citric acid, an AHA, so not suitable for the moment

To repair my skin barrier in readiness for tretinoin - has potential acne trigger compared to good molecules but will do for now. Preference is for a barrier repair with no citric acid as I already have that in the post acne serum
