Using Polysilicone-15 in winter: the season brings cold air, indoor heating and moisture loss, 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 winter does to your skin

Cold air and indoor heating strip moisture, so layer hydrating toners and essences under a richer cream or occlusive.

How that changes Polysilicone-15

Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. Polysilicone-15 works on sun damage & photoageing, and it is normally applied AM.
