## How it works

The Hyper Acid4 AHA BHA PHA LHA 30 Serum 20ml (Wash-off) is a 20ml wash-off serum, used after cleansing. The exfoliant it is built around is Salicylic Acid, named sixteenth on its own ingredient list. The same list carries Niacinamide, Allantoin and Gluconolactone, so the exfoliant is not the only thing on it worth naming. How much of the Salicylic Acid stays on the skin, and for how long, is decided by the wash-off serum format rather than by the list alone. Isntree sells this Salicylic Acid wash-off serum in Korea, and this is that version.

## How to use

1. Use the Hyper Acid4 AHA BHA PHA LHA 30 Serum 20ml (Wash-off) after cleansing.
2. A thin layer over dry skin, kept clear of the eye area and the corners of the mouth.
3. Rinse or roll it off as the pack directs, then follow with a hydrating layer and your moisturizer the same evening.
4. Do not pair it with an acid toner or a retinoid in the same routine.

## FAQ

### Where does this wash-off serum go in my routine?

Straight after cleansing, and it comes off again before the rest of your routine goes on. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Salicylic Acid and not three changes at once.

### What else is on the list besides Salicylic Acid?

Niacinamide, Allantoin and Gluconolactone. The order they are printed in on this wash-off serum's panel is the order on the box, so you can see where Salicylic Acid sits relative to them. Further down the same panel: Lactic Acid, Glycolic Acid and Capryloyl Salicylic Acid.
