One minus
Overuse can scratch sensitive skin
Both recommended for Texture / Pores.

See alternativesTexture-smoother with visible payoff
The why
A two-step acid peel with glycolic acid, salicylic acid, and witch hazel that Redditors use for texture, clogged pores, and dullness. Studies back the acne-clearing angle, but the alcohol and fragrance make overuse stingrier than the label suggests.
One minus
Overdoing it wrecks the barrier
Good forDry Skin
Both recommended for Acne.
