First, know which kind of laser you had

Aftercare depends on how deeply the laser worked. Low-energy toning barely disturbs the surface, while ablative lasers create tiny wounds that need several days to heal. Check your aftercare sheet, or ask your doctor which category applies to you.

Laser type	Examples	Typical recovery	Makeup usually OK
Toning	Pico toning, laser toning	None to mild redness for a few hours	Same evening or next morning
Light-based pigment	IPL photofacial	Spots darken and flake for 5–7 days	Next day, applied gently
Vascular	Excel V	Mild redness for 1–2 days	Next day
Non-ablative fractional	Pico fractional	1–3 days of redness	After 1–2 days
Ablative fractional	CO2 fractional	5–7 days of redness and crusting	Once crusts have shed, about a week
Spot removal	Mole and skin tag removal	Healing patch for 5–10 days	Around, not over, the patch

Your day-by-day timeline

Day 0: treatment day

Expect warmth and pinkness; a cool compress helps.
Apply the soothing cream or moisturizer you were given.
Skip makeup until your doctor says it is fine.
Avoid saunas, hot baths, intense exercise and alcohol tonight.
Sleep on a clean pillowcase.

Days 1–3

Cleanse morning and night with a gentle cleanser and lukewarm water; pat dry.
Moisturize often, and apply sunscreen every morning.
After IPL, treated spots darken; this is expected.
After CO2, keep treated areas moist with the ointment prescribed, and never pick crusts.

Days 4–7

Flaking or fine peeling is normal; let it shed on its own.
CO2 crusts usually lift during this window, leaving pink new skin.
No scrubs, peels or cleansing brushes yet.

Weeks 2–4

Reintroduce actives one at a time, usually vitamin C first, then retinoids, once skin feels completely calm.
Keep sun protection strict, especially through a series.
Return for your next session at the interval your doctor recommends.

What is normal in the first week

Mild redness, warmth like a light sunburn, slight swelling for a day or two, especially around the eyes, and temporary dryness are all normal. After pico fractional, skin can feel like fine sandpaper as tiny micro-crusts form and shed. After IPL, freckles and sun spots look darker before they fade. These changes mean the skin is responding, not that something has gone wrong.

Sleep, hydration and lifestyle

After CO2 laser, sleeping with your head slightly raised for the first night or two can reduce swelling.
Drink plenty of water and keep alcohol to a minimum for a few days.
Smoking slows healing; avoid it if you can, especially after resurfacing.
Keep hair products, phones and hands away from treated skin.

Products to use and to pause

Use	Pause until skin settles
Gentle, fragrance-free cleanser	Retinol, retinoids and tretinoin
Plain moisturizer with ceramides or panthenol	AHA, BHA and other exfoliating acids
Broad-spectrum sunscreen, often mineral	Scrubs, peeling gels and cleansing brushes
Prescribed ointment after CO2	High-strength vitamin C and fragranced products

Sun protection is part of the treatment

Laser-treated skin reacts more easily to UV and visible light, which can trigger new pigmentation, especially in medium to deeper skin tones. Use sunscreen daily, reapply outdoors, and add a hat and sunglasses. Read sun protection after pico toning and laser, and avoid tanning between sessions.

Aftercare during a series

Toning lasers are usually repeated every one to two weeks. Keep the same gentle routine between sessions, and tell your doctor before the next one about any irritation, new medications, a recent tan or a cold sore. If you are only in Seoul for part of a course, ask for written settings and dates so a doctor at home can continue. Our guide to how many pico toning sessions you need explains typical courses.

When to contact the clinic

Blisters, oozing or crusts on a toning or IPL area
Pain that increases rather than settles
Spreading redness, warmth, pus or fever
A cold sore outbreak in or near the treated area
Dark patches appearing a few weeks after treatment

Most of these are manageable when caught early. See normal side effects vs when to contact us.

Traveling after laser

You can usually fly after toning the next day. Cabin air is dry, so moisturize on board and close the window blind on day flights. After CO2 or fractional lasers, allow the timeline above before you fly if you can. See can I have laser treatment right before a flight? For general advice, visit our aftercare page, or book a consultation to plan your laser around your trip.

How soon can I wash my face after laser?

Usually the same evening, using a gentle cleanser and lukewarm water. Pat dry rather than rubbing. After CO2 laser, follow the specific cleansing instructions you were given.

When can I wear makeup after laser?

After toning, often the same evening or next morning; after fractional lasers, after one to two days; after CO2, once crusts have shed. See when can I wear makeup after laser?

When can I use retinol again?

Most people restart retinoids about one to two weeks after toning or IPL, and later after CO2 laser, once skin feels completely calm. Your doctor will confirm timing for your skin.

Is peeling normal after laser?

Fine flaking is normal after IPL and fractional lasers, and crusting is expected after CO2. Let it shed naturally and do not pick or scrub.

Can I go to the gym after laser?

After toning, light exercise the next day is usually fine. Avoid intense, sweaty workouts and saunas for at least a day or two, and longer after CO2 laser.

What should I avoid after pico toning?

Avoid heat, scrubs, strong actives and unprotected sun for a few days. See what should I avoid after pico toning?
