What is this product?

This is a strong exfoliant wearing a gentle label, so buy it for congestion and rough texture on oily skin and not because it says 저자극: four acids sit in the first eight of only 15 ingredients (capryloyl salicylic acid, glycolic, lactic and citric), with nothing to soften them, no thickener, no oil and no occlusive to blunt them. Zeroid publishes no strength for any of the four and no pH for the finished product, and the label itself caps use at one to two times a day on a cotton pad, says to stop on redness, swelling, itching or stinging, and says not to apply it to broken skin, eczema or dermatitis. It carries no functional cosmetic designation, so nothing here is state-reviewed for tone or wrinkles.

What makes it different?

Almost nothing else is in it: at 200ml the list runs 15 ingredients with no thickener, no film former and no oil, so the acids arrive undiluted by texture and the toner dries in seconds. The other distinguishing choice is the acid mix itself: an LHA, which is lipophilic and works inside the pore, alongside two AHAs that work on the surface, plus zinc PCA for sebum. What it gives back is thin, just panthenol, betaine, a hydrolysed hyaluronic acid and a pseudoceramide, all in the back half, so dry or reactive skin needs a repair layer after it and should treat sunlight on treated areas as the label warns, and opened it has 12 months of life.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.
