iamskin notes

A rinse-off serum designed for intensive exfoliation after just one minute of use.

ISNTREE Hyper Acid 4 AHA BHA PHA LHA 30 Serum is formulated with an optimized 30% ACID 4 Formulation (AHA 15.3%, BHA 0.1%, PHA 14.61%, LHA 0.01%). It also features niacinamide, allantoin (moisturizing and soothing), charcoal powder (clarifying), and peat water (improves cell turnover and skin elasticity). This high-performance rinse-off serum exfoliates away dead skin cells, reduces excess sebum production, and smooths the skin texture, revealing a bright and even skin tone.

How to use

1. After cleansing, apply 2-3 drops on the skin, avoiding the eye and lip areas. Manage the product into the skin for about 1 minute, and rinse thoroughly with lukewarm water. 

NOTE: This is a high-concentrated exfoliant serum that contains four types of acids that help reduce dead skin cells and excessive sebum production. Recommended to use the product 1 to 2 times a week. 

Due to the high-concentration acids, if you leave the product on the skin for too long, it may cause irritation. It is recommended to remove the product from the skin one minute after application.
