1,2-Hexanediol in winter: how to adjust

⏱ 1 min read
⚡ Quick answer: Using 1,2-Hexanediol 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.

Using 1,2-Hexanediol 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.

The reason so many Korean products can print 무방부제 (mubangbuje, preservative-free) on the box. 1,2-Hexanediol is a solvent and humectant that also makes life difficult for microbes, so it is not classified as a preservative even though it is doing preservative work. Honest ingredient, slightly dishonest marketing.

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 1,2-Hexanediol

Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. 1,2-Hexanediol works on dehydration (water-poor skin), and it is normally applied BOTH.
