AHA (Glycolic/Lactic) in autumn: how to adjust
Using AHA (Glycolic/Lactic) 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.
Water-loving acids that resurface the top layer. Lactic is gentler; glycolic is stronger. SPF a must.
