IsNtree Hyper Acid4 AHA BHA PHA LHA 30 Serum is an intensive exfoliating peeling serum that removes dead skin cells, deeply cleanses pores, controls excess sebum, and helps prevent clogged pores and comedones.
With regular use, it maintains a smoother and clearer complexion, brightens blackheads and sebaceous filaments, reduces the appearance of pigmentation and post-acne marks, and improves overall skin texture. The formula softens rough skin, eliminates flakiness, minimizes enlarged pores, and supports acne-prone skin.
