Cleansers

The double cleanse is the one Korean habit worth adopting even if you ignore everything else. Oil first, to dissolve sunscreen, makeup and the sebum of the day. Foam second, to clear what the oil left behind.

Sunscreen in particular does not come off with a water-based cleanser alone, and that is the single most common cause of congestion in people who are otherwise doing everything right.

Mornings are different — most skin needs nothing more than a gentle low-pH foam, or plain water. And if your face feels tight afterwards, the cleanser is too strong; that is not your skin being oily. See Pores & Blackheads if congestion is the main thing you are fighting.
