1,2-Hexanediol in spring: how to adjust
Using 1,2-Hexanediol in spring: the season brings rising UV and pollen-season reactivity, 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 spring does to your skin
Fluctuating temperatures, pollen and sensitivity, and rising UV mean a gentle, barrier-supportive routine with reliable daily SPF.
How that changes 1,2-Hexanediol
Spring is when UV climbs while skin is still adjusting out of winter — keep the barrier steady and let sunscreen do the heavy lifting. 1,2-Hexanediol works on dehydration (water-poor skin), and it is normally applied BOTH.
