AHA (Glycolic/Lactic) in winter: how to adjust
Using AHA (Glycolic/Lactic) 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.
Water-loving acids that resurface the top layer. Lactic is gentler; glycolic is stronger. SPF a must.
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 AHA (Glycolic/Lactic)
Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. AHA (Glycolic/Lactic) works on dullness & glow, dark spots & tone, pores & texture, and it is normally applied PM.
