⏱ 1 min read
⚡ Quick answer: Using AHA (Glycolic/Lactic) 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.

Using AHA (Glycolic/Lactic) 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.

Water-loving acids that resurface the top layer. Lactic is gentler; glycolic is stronger. SPF a must.

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 AHA (Glycolic/Lactic)

Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. AHA (Glycolic/Lactic) works on dullness & glow, dark spots & tone, pores & texture, and it is normally applied PM.

⚠️ Keep apart from: Retinol, BHA (Salicylic) — especially when seasonal dryness has already made skin more reactive.
