Using Polysilicone-15 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.

A UV filter attached to a silicone backbone, permitted in Korea and the EU but not in the United States — one small piece of why Korean sunscreens feel the way they do. It absorbs UVB, stays put on skin thanks to its size, and adds almost no weight. Not a UVA filter, so it always travels in company.

What autumn does to your skin

Dropping humidity is the classic time to repair the moisture barrier and slowly transition to richer textures.

How that changes Polysilicone-15

Autumn is the classic Korean repair season — humidity drops, summer sun damage surfaces, and richer textures start to feel right again. Polysilicone-15 works on sun damage & photoageing, and it is normally applied AM.
