- Why people love it
- Water-light texture disappears fast
#2
Best for Dehydration

- Size: 50 ml
The why
A beta-glucan serum with a very short, humectant-heavy formula that people use for dehydration and barrier recovery. It layers well on damp skin and suits tret users, but reformulation complaints and occasional breakouts are real.
One minus
Reformulation threads are brutal — newer bottles read less hydrating
Good forDry Skin, Sensitive Skin
Both recommended for Dehydration.
