Ethylhexylglycerin in summer: how to adjust

Using Ethylhexylglycerin 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.

Almost always sits next to phenoxyethanol on a Korean label, because its job is to make that phenoxyethanol work harder at a lower level. It also acts as a mild skin conditioner. Worth knowing: it is one of the less common contact allergens, so if a patch of products all sting you, it is one to check against.

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 Ethylhexylglycerin

Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. Ethylhexylglycerin works on its usual targets, and it is normally applied BOTH.
