Mandelic Acid in summer: how to adjust
Using Mandelic Acid in summer: the season brings heat, humidity, sweat and peak UV, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.
Derived from bitter almonds and prized precisely because it is slow. The bigger the acid molecule, the less briskly it penetrates — which is exactly what reactive skin wants from an exfoliant.
What summer does to your skin
Heat, humidity, sweat and excess oil call for lightweight, fast-absorbing layers and a high, re-applied sunscreen.
How that changes Mandelic Acid
Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. Mandelic Acid works on rough & uneven texture, acne & breakouts, dark spots & tone, reactive & easily-stung skin, and it is normally applied PM.
