Lactic Acid in autumn: how to adjust

⏱ 1 min read
⚡ Quick answer: Using Lactic Acid in autumn: the season brings falling humidity and barrier recovery, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.

Using Lactic Acid in autumn: the season brings falling humidity and barrier recovery, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.

The AHA for people whose skin gets tight after exfoliating. Lactic acid holds water as well as loosening dead surface cells, so it tends to leave skin less parched than its sharper relatives.

What autumn does to your skin

Dropping humidity is the classic time to repair the moisture barrier and slowly transition to richer textures.

How that changes Lactic Acid

Autumn is the classic Korean repair season — humidity drops, summer sun damage surfaces, and richer textures start to feel right again. Lactic Acid works on rough & uneven texture, dryness & dehydration, dullness & glow, and it is normally applied PM.

⚠️ Keep apart from: Retinol, Retinaldehyde (Retinal), AHA (Glycolic/Lactic), BHA (Salicylic) — especially when seasonal dryness has already made skin more reactive.
