The evening routine: where the heavy lifting happens
Evening is when retinoids, exfoliating acids and richer occlusives belong — light degrades some of them and they can increase sun sensitivity. The organising principle is not doing everything every night: alternate, and give skin recovery evenings.
Why evening
Retinoids degrade in light, exfoliating acids increase sun sensitivity, and richer textures that would sit badly under makeup are fine overnight. Skin does run on a measurable daily rhythm — cell turnover and water loss both vary across the day — but that is a much thinner basis than night-cream marketing implies. The reasons above are the ones actually deciding this.
Alternate, do not stack
A retinoid one night, an exfoliant another, and plain barrier support on the nights between. Skin cycling is simply a name for this, and it exists because stacking actives nightly is the fastest route to a damaged barrier.
Sleeping masks
An occlusive final layer over your moisturiser, most useful in winter or on skin that wakes up tight. It goes over the routine, not instead of it.
Recovery nights are not wasted
Nights with only cleanser and moisturiser are part of the plan, not a lapse. Barrier recovery is what makes the active nights tolerable and therefore effective.

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.
