The short answer
Korean skincare shopping after a procedure: what should you hold off on?
Hold off on everything new on the treated area, sun protection included, until the clinic that treated you says which products are fine and from which day. Dermatology guidance says aftercare is individual, that treated skin can be sensitive, that makeup may need to wait a few days, and that rubbing or scratching treated skin can lead to infection. The Academy's general sunscreen advice, SPF 30 or higher, broad spectrum, water resistant and reapplied every two hours, is written for skin in general rather than for freshly treated skin, so ask what your clinic wants on the treated area. Show them the labels of anything you bought, and start the rest once the skin has settled.

Aftercare is individual, so ask first.
The American Academy of Dermatology says that after acne scar treatment your dermatologist gives you aftercare instructions for your skin, may recommend specific products because treated skin can be sensitive, and may ask you to stop wearing makeup for a few days. What applies after one treatment may not apply after another.
That is why a general shopping rule is less useful than a quick question to the clinic. Take photos of the ingredient labels of anything you want to use, and ask whether it is fine on treated skin and from which day.
American Academy of DermatologyWhat to hold off on until the clinic says.
The Academy's chemical peel guidance warns that rubbing or scratching treated skin can cause infection, and that applying makeup before the skin heals raises the risk of infection and scarring. Tools and products whose job is to scrub, peel or rub fit poorly with those warnings in the first days.
The Academy's laser preparation advice also asks patients to tell the dermatologist about isotretinoin and other medicines. If a product you are considering contains an active ingredient you already use as a medicine at home, mention it too.
- New products on the treated area, until the clinic confirms them.
- Scrubs, peeling pads, cleansing brushes and anything that rubs.
- Makeup on the treated area, until the clinic says it is fine.
- Tanning products and time in strong sun.
Sun protection: ask what applies to treated skin.
The Academy's laser hair removal guidance advises keeping direct sunlight off treated skin and avoiding indoor tanning. Its general sunscreen page describes SPF 30 or higher, water resistant and broad spectrum, applied about 15 minutes before going out and reapplied every two hours and after sweating. That page is about skin in general, not about an area treated a day ago, so ask the clinic which product they want on the treated area and from which day.
Shade needs no approval. Shopping streets in summer can mean hours outdoors, and a hat, shade and shorter walks between shops cost nothing to adopt while you wait for that answer.
