Using Sodium PCA 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.

Skin makes its own water-binding salts in the top layer; sodium PCA is a cosmetic version of one of them. It is a supporting act rather than a headline — you will see it in the middle of an ingredient list on hydrating toners and essences, quietly doing the thing that stops a light formula from evaporating off.
