The Isntree Hyper Acid4 AHA BHA PHA LHA 30 Serum is a potent Korean skincare treatment designed to deliver rapid exfoliation and refine skin texture. This rinse-off serum combines four key acids—AHA (Glycolic and Lactic Acid), BHA (Salicylic Acid), PHA (Gluconolactone), and LHA (Capryloyl Salicylic Acid)—to effectively remove dead skin cells, unclog pores, and regulate sebum production, resulting in a smoother and more even complexion. Additional ingredients like Niacinamide and Allantoin help brighten and soothe the skin, while Peat Water and Charcoal Powder contribute to improved elasticity and oil-water balance

After cleansing, apply 2–3 drops of the serum onto your skin, avoiding the eye and lip areas. Gently massage the product into your skin for about 1 minute. Rinse thoroughly with lukewarm water. Use 1–2 times a week, preferably at night. If used during the day, follow up with sunscreen
