What a Korean routine looks like during oral isotretinoin

During an oral isotretinoin course the routine almost always simplifies to a mild cleanser, a rich fragrance-free moisturiser, an ointment for lips and sunscreen, with actives and exfoliants set aside. Skin is commonly described as drier, more fragile and more easily irritated than usual, and the same is true of lips, eyes and the inside of the nose. This is a prescribed medication with monitoring attached, so anything about the course itself — including starting, pausing or stopping — is entirely for the prescribing clinician.

Everything the routine was doing before is now the medication's job

The oil-control toner, the BHA, the clay mask, the acne spot gel: on an isotretinoin course most of these become redundant at best and abrasive at worst. Oiliness usually falls sharply, and continuing to fight it strips a surface that is already struggling. Korean routines built around 모공 (mogong, 'pores') and mattifying tend to age badly here. What people are commonly advised to keep is short and boring, and the boringness is the point — fewer variables while skin is behaving unusually, and fewer things to blame if something flares.

The parts of you nobody warns about

Lips are the near-universal complaint, and a plain occlusive ointment used often beats any tinted balm. Dryness inside the nose, dry or gritty eyes, and skin on hands, arms and shins that cracks in cold air are all commonly reported. Contact lens wearers often find their lenses less comfortable. None of this is fixed by facial skincare, so extend the thinking: an unscented body cream, an ointment by the bed, humidity indoors in a Korean winter. Anything that is painful, worsening or affecting your vision goes to your doctor, not a shopping list.

Procedures, waxing and the timing question

Skin is commonly described as more fragile during and after a course, and clinics routinely ask about isotretinoin before waxing, peels, laser and other treatments. The long-standing blanket caution around resurfacing has been re-examined by specialists in recent years and expert opinion has softened for some procedures, but that is precisely the judgement that belongs to the doctor holding the device — not to you, and not to a beauty therapist working from a form. Declare it, in writing, every time, including for eyebrow threading and salon facials where people forget to mention it.

What Korean products still earn a place

Thick unscented creams, 판테놀 (panteneol, panthenol) and ceramide-led barrier products, cream cleansers that rinse without squeaking, and sleeping packs used purely as an overnight occlusive. Sheet masks are a mixed case: the fabric is harmless, but many essences carry alcohol, fragrance or extracts that sting on compromised skin, and a stinging mask is telling you something. Sunscreen stays, and photosensitivity is commonly flagged during a course. Anything labelled brightening, peeling, resurfacing or tingling can wait until the prescriber says otherwise.
