https1uc4 review for 5% Niacinamide + 1% Zinc – Niacinamide Magic Face Serum

this was such a game changer from other niacinamide serums. all i could find were 10% and i know it's too high of a percentage until i stumbled on this product. its such a gentle formula that really improved my skin barrier health and strength so much in just a few days. i always use this a night it's so good for calming irritation and i helps my skin so much. they weren't lying when they said this was magic - really saved my skin.
