Isntree Hyper ACID4 30 Serum 20ml

Product Description

The ISNTREE Hyper ACID4 30 Serum is a rinse-off exfoliating serum designed to help smooth skin and clear away built-up dead skin cells. It uses a 30% blend of four exfoliating acids - AHA, BHA, PHA and LHA - to support a cleaner-feeling surface and help reduce excess sebum for a more refined look.

What makes it stand out is the “after just one minute” approach: apply 2–3 drops after cleansing, gently massage for about a minute, then rinse thoroughly. It’s a great fit if you want a quick, targeted treatment to support a more even texture and help unclog pores. The formula also includes niacinamide and allantoin to help keep skin feeling comfortable during exfoliation.

Key ingredients/technology include glycolic acid and lactic acid (AHA), salicylic acid (BHA) plus PHA components like gluconolactone, and LHA (capryloyl salicylic acid). Charcoal powder and peat water are included for extra “oil-control” and conditioning benefits, making this a high-impact step in the ISNTREE routine.
