BHA (Salicylic) in winter: how to adjust
Using BHA (Salicylic) in winter: the season brings cold air, indoor heating and moisture loss, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.
Salicylic acid dives into oily pores to decongest. Ideal for blackheads & breakouts.
What winter does to your skin
Cold air and indoor heating strip moisture, so layer hydrating toners and essences under a richer cream or occlusive.
How that changes BHA (Salicylic)
Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. BHA (Salicylic) works on acne & breakouts, pores & texture, oil control, and it is normally applied PM.

What is BHA and what does it do?
BHA, usually salicylic acid, is an oil-soluble exfoliant that can penetrate pores to dissolve oil and dead skin, helping refine the look of texture and blemish-prone skin. In Korean routines it's used a few times weekly, with sunscreen by day, to avoid over-exfoliating.
What is the difference between AHA and BHA?
AHAs like glycolic and lactic acid are water-soluble and work on the skin's surface to brighten and smooth, while BHA like salicylic acid is oil-soluble and gets into pores. In Korean skincare both are used sparingly, a few times weekly, always with daily sun protection.
