Tacrolimus, pimecrolimus and the routine built around them
Topical calcineurin inhibitors are prescribed as a steroid-sparing option in some situations, commonly for delicate areas such as the face and eyelids, and a burning or stinging sensation on application is frequently reported early on. The supporting routine is the usual bland one — gentle cleansing, a fragrance-free moisturiser, daily sun protection — with actives paused. What they are for, where they go and how long they continue is decided by the prescribing clinician.
Why clinicians reach for them
They are used partly because they do not carry the skin-thinning concerns associated with prolonged potent steroid use, which makes them attractive for eyelids, around the mouth and other thin-skinned areas where steroids are handled cautiously. They also carry a warning label about a theoretical long-term risk that has been debated for years and is not settled in the way the label's prominence suggests. That debate belongs in the consulting room. What it means for you practically is that this is a prescription with a conversation attached, and the conversation is worth having properly.
The stinging, and what makes it worse
A burning, warm or stinging sensation shortly after application is commonly reported and often described as easing with continued use. Several things reliably make it worse: applying to skin that is already raw, applying immediately after a hot shower, and — with tacrolimus specifically — alcohol, where a flushing reaction has been reported. In Korea that last one has a social dimension worth planning for around 회식 (hoesik, work dinners). If the sensation is severe or not settling, that is information for your prescriber rather than a problem to solve with a cooling mask.
Sun protection is part of the plan
Sun protection is routinely emphasised with these medications, and it is one of the areas where a Korean routine genuinely earns its place. The local sunscreen category is unusually good at light textures and mineral options that do not sting, which matters when the treated area is an eyelid or a raw patch beside the nose. Hats, sunglasses and shade do work that no formula matches. Ask your prescriber how sunscreen and the medication should be sequenced, because the answer depends on the product and the area.
What to keep and what to shelve
Keep a mild cleanser, a plain unscented moisturiser used generously, and sun protection. Shelve acids, retinoids, strong vitamin C, scrubs and anything that tingles, at least while things are active. Korea's 진정 (jinjeong, 'calming') category overlaps neatly with what is wanted here — centella, madecassoside, panthenol, heartleaf — but read for fragrance and alcohol, and be wary of adding a brand-new product to skin that is already reacting. One change at a time, reported at your next appointment.

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 often should you exfoliate in a Korean routine?
Once or twice a week for most people, up to three times for oily and resilient skin. Frequency matters far more than strength — a mild acid used consistently beats a strong one that forces you to stop.
