⚡ Quick answer: Using Dimethicone 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.

Using Dimethicone 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.

Silicones took an undeserved reputational beating. Dimethicone does not suffocate skin — it is a well-tolerated film former, and it is most of the reason a Korean sunscreen applies so smoothly.

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 Dimethicone

Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. Dimethicone works on damaged moisture barrier, rough & uneven texture, dryness & dehydration, and it is normally applied BOTH.

What to layer it with
