Lactic Acid in winter: how to adjust

⏱ 1 min read
⚡ Quick answer: Using Lactic Acid 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.

Using Lactic Acid 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.

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 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 Lactic Acid

Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. 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.
