Laser appointments: what the routine pauses, and what it must not skip
Before laser work, clinics commonly ask patients to avoid tanning and sun exposure, pause exfoliating actives and retinoids, and declare medications — oral isotretinoin and photosensitising drugs in particular. Afterwards the routine usually reduces to gentle cleansing, a plain moisturiser and strict sun protection for as long as the clinic specifies. Every one of those decisions is device-, setting- and person-specific, so the clinic's written instructions override anything written here.
A tan changes the calculation
Many lasers work by targeting pigment, which means recent sun exposure or a tan alters how the treatment behaves and raises the risk of unwanted pigment changes afterwards. This is why clinics ask about sun and why the honest answer matters more than the convenient one. It also makes the run-up to an appointment a poor time for a beach weekend, and it makes the weeks after one a poor time too. Sunscreen before and after is not a suggestion here; it is part of the procedure.
The medication questions
Photosensitising medications — some antibiotics among them — and a history of oral isotretinoin are standard items on a consent form for good reasons. The long-standing blanket caution about resurfacing after isotretinoin has been re-examined by specialists in recent years and expert opinion has softened for some procedures, but that judgement belongs to the doctor operating the device. Declare it either way. A history of cold sores is another common question, because some treatments are associated with triggering an outbreak and clinicians sometimes plan for that in advance.
Afterwards, the routine gets boring on purpose
Gentle cleansing, a plain moisturiser without actives or fragrance, and sun protection once the clinic confirms the surface tolerates it. Any crusting or flaking is left alone. Heat is a recurring theme in Korean aftercare specifically — 찜질방 (jjimjilbang), saunas, hot springs, steamy showers and hard training all raise skin temperature and blood flow, and clinics routinely ask patients to postpone them. If your Korea itinerary is built around a bathhouse day, mention it before booking rather than after, because the sequencing usually cannot be fixed retrospectively.
Expectations, sold and real
Korean clinics market 레이저 토닝 (leijeo toning, 'laser toning') and similar treatments as course-based, and course-based is generally accurate — single-session transformation is a marketing frame rather than a typical outcome. Ask what result is realistic for your skin and what the clinic does if it does not materialise. Ask about pigment risks for your skin tone specifically, because responses differ. Increasing pain, spreading redness, blistering or discharge afterwards means contacting the clinic promptly rather than waiting to see.

What is the 10-step Korean skincare routine?
The 10-step Korean skincare routine is a layered framework popularized in Korea: oil cleanser, water cleanser, exfoliant, toner, essence, serum or ampoule, sheet mask, eye cream, moisturizer and sunscreen. It's a customizable menu, not a daily mandate, and most people use only the steps their skin needs.
What is a good Korean skincare routine for beginners?
A simple beginner Korean routine is a gentle cleanser, a hydrating toner, a lightweight moisturizer and daily sunscreen, adding one targeted serum once your skin adjusts. Introduce actives slowly, one at a time, and patch-test, following the Korean principle of gentle, barrier-friendly care over many steps at once.
How many steps should a Korean skincare routine have?
As few as three: cleanser, moisturiser and sunscreen. The ten-step routine was a Western marketing frame rather than a Korean rule — most Koreans use a handful of products daily and add extras occasionally.
How long before Korean skincare shows results?
Hydration shows within days. Texture and breakouts take about four to eight weeks. Pigmentation and fine lines take three months or more. Judging anything earlier than its timeframe is the most common reason people abandon products that were working.
