Peels: what usually comes out of the routine, and when it returns

Before a peel, clinics commonly ask patients to pause retinoids, acids, scrubs and anything that has recently irritated the skin, and to declare every prescription and recent procedure. Afterwards the routine typically shrinks to a bland cleanser, a plain moisturiser and sun protection until the clinic says otherwise. The only timeline that counts is the written one your clinic gives you, and it varies by peel, by depth and by person.

What the pre-appointment questions are actually for

The form asking about retinoids, recent waxing, cold sores, isotretinoin and recent sun exposure is not bureaucracy. Skin that has been exfoliated, waxed, burnt or medicated behaves differently under an acid, and a peel applied to unexpectedly thin skin is where problems come from. Declare everything, including products you think are too gentle to count, brow threading, a facial last week and any prescription from a different doctor. Bring the actual bottles or photographs of the ingredient lists if you are unsure what is in them.

The gap between a clinic peel and a home one

Korean shelves are full of 필링 (piling) products — pads, gels, powders, gommage sticks — and they operate in a different league from a clinic 시술 (siseul, 'procedure'). The risk is not that the home version does too much; it is that people keep using it during the run-up to an appointment without registering it as exfoliation, because it is sold as a toner or a mask. Read the ingredient list for acids and enzymes rather than the front of the packet, and mention anything you have been using.

Afterwards: fewer products, not better ones

The standard aftercare pattern is bland cleansing, a simple moisturiser without actives or fragrance, and sun protection once the clinic confirms the skin surface tolerates it. This is the moment people most want to help things along with a new 진정 (jinjeong, 'calming') ampoule, and it is the worst moment to introduce an unfamiliar product. Peeling that appears should be left to come away on its own; picking or scrubbing it is how marks form. Heat is the underrated variable — saunas, 찜질방 (jjimjilbang), hot showers and hard exercise are commonly postponed.

When to call rather than search

Pain that increases rather than eases, spreading redness or warmth, blistering, discharge or fever are reasons to contact the clinic promptly. Do not wait to see whether a forum agrees. Visitors to Korea should sort the follow-up question out before booking: who covers complications, how to reach them, and what happens once you have flown home, at which point a licensed doctor where you live becomes the person to call. Ask what the clinic expects normal recovery to look like, so you can recognise when it is not.
