Isntree Hyper Acid 4 AHA BHA PHA LHA 30 Serum combines four acid types in a rinse-off formula for rough texture, excess oil and the appearance of congested pores. Charcoal gives it a distinctive dark color, while glycerin, niacinamide and allantoin round out the formula. Use sparingly in your evening routine and rinse thoroughly after one minute, following with gentle moisturizing care.\u003c\/p\u003e\u003ch2\u003eIsntree Rinse-Off Serum 101\u003c\/h2\u003e\u003cp\u003eIsntree Hyper Acid 4 is a concentrated rinse-off exfoliant with a combined 30% acid blend.
