undefined review for Niacinamide 10% + Zinc 1%
I would try incorporating this into your routine weekly first before you use it daily! you may have introduced this too quickly/much for your skin so it’s not tolerating it well
Yes, I can't use 10% Niacinamide too 😢
I really want to try this proudct so Thank you for sharing
You should insert it slowly to your routine like ...at first use it once weekly then twice weekly and keep your self in that way untill you figure out how many times in the week you need to use it .
Have you used 5% before?
