How it works

BYRODAM describes the pore approach in three steps. First, the PHA gently lifts the dead skin cells sitting over pores so trapped sebum can be released instead of building up. Next, the formula settles into the skin’s surface to help clear away impurities and loosen excess sebum. Finally, the emptied pores are filled with hydration, which is what helps them look tighter and more refined. Because the peeling is PHA-based rather than a harsher acid, it runs alongside the herbal Samultang blend and the brand’s “Korean herbal collagen” idea, so the aim is sebum balance and moisture rather than stripping — the brand frames healthy-looking skin as starting from sebum control. The four things it leans on are skin hydration, PHA peeling, the herbal Samultang formula, and Korean herbal collagen.

How to use

Use the dropper to place an appropriate amount onto cleansed skin, then pat gently in light layers until it absorbs. Follow with a moisturizer to seal in the deep hydration the ampoule leaves behind. Because the PHA is formulated to be low-irritation, it is meant for regular daily use rather than occasional peeling. If your skin runs sensitive, ease it into your routine and take extra care when layering it with other strong actives.

Good to know

The brand’s shorthand for the finish is “hydration up, irritation down”: it is built to support pore and sebum care while still feeling gentle, and it is described to improve the feeling of inner dryness rather than leaving skin tight. The recipe traces back to a Korean herbal doctor’s Samultang formula and the brand’s herbal-skincare research. Even so, the more sensitive your skin is, the more careful you should be — patch-test on a small area before your first full use and introduce it gradually.
