Hyperpigmentation
Hi Beauties,
My friend uses 5 actives/acids in her routine to treat hyperpigmentation. For me, I only use 1 in the morning and 1 at night. I usually switch my products after 3 months because I feel the effect gets plateau.
I am curious: is it better to use multiple actives/acids at once for a long period of time (like my friend's routine) or use 1-2 max but change them up every few months?
What are your experiences?
