After gentle lasers such as laser toning, pico toning or Genesis, most people can wash their face the same evening or the next morning with lukewarm water and a mild cleanser. After more intensive or ablative lasers, the doctor may ask you to wait longer and follow special instructions. Always follow the written aftercare from Re:berry Hongdae.

Why does timing matter?
Lasers create controlled effects in the skin, ranging from very mild heating to tiny areas of injury. In the first hours, skin can be sensitive, warm and slightly swollen. Washing too vigorously or with hot water can irritate it. Waiting a few hours and cleansing gently gives the skin a calm start.
Timing by type of laser
- Laser toning and pico toning: usually the same evening or next morning
- Genesis laser: typically the same day, as it is very gentle
- Pigment spot treatments: often next day, keeping the area dry if a patch or ointment was applied
- Fractional or ablative lasers: follow specific written instructions, which may include special cleansing
How should I wash my face after laser?
- Wash hands first
- Use lukewarm water and a mild, fragrance-free cleanser
- Apply with fingertips using light movements; no scrubbing
- Pat dry with a clean soft towel
- Apply the recommended moisturizer and sunscreen
What should I avoid?
- Hot water, saunas and jjimjilbang for a few days
- Scrubs, exfoliating acids, retinoids and cleansing devices for about 3–7 days
- Picking at any crusts or darkened spots

What about moisturizer and sunscreen?
After washing, apply a simple, fragrance-free moisturizer to support the barrier. Many clinics recommend products with ceramides, panthenol or centella. Sunscreen is essential after lasers because treated skin can be more sensitive to UV, which raises the risk of new pigmentation. Choose a broad-spectrum SPF 30 or higher, reapply when outdoors, and add a hat for walks around Hongdae or along the Gyeongui Line Forest Park. If anything stings strongly, rinse it off and contact the clinic for advice. For the first few nights, use a clean pillowcase and keep hair products away from the face.

Related questions
Can I use a foam cleanser after laser?
A gentle, low-pH foam cleanser is often fine after mild lasers. Avoid strong foaming cleansers with sulfates, fragrance or exfoliants for several days. If unsure, ask the clinic which products suit your skin. Rinse with lukewarm water and pat dry gently rather than rubbing with a towel.
What if spots darken after laser?
Some pigment treatments cause spots to darken and form tiny crusts before flaking off within about a week. Wash gently around them and do not pick. Protect the area from sun to reduce the risk of new pigmentation. This darkening is usually expected rather than a sign of a problem.
Can I swim after laser treatment?
Most doctors suggest avoiding pools and the sea for several days because chlorine, salt and bacteria may irritate healing skin. The exact time depends on the laser used, so follow your written aftercare. Saunas and hot tubs are also best avoided during the same period, because heat can increase redness.
