BHA (Salicylic) in summer: how to adjust
Using BHA (Salicylic) in summer: the season brings heat, humidity, sweat and peak UV, 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 summer does to your skin
Heat, humidity, sweat and excess oil call for lightweight, fast-absorbing layers and a high, re-applied sunscreen.
How that changes BHA (Salicylic)
Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. 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.
