Frequently asked

What does beta-glucan do compared to hyaluronic acid?

Both draw and hold water, but beta-glucan is heavier and more film-forming, which many people find more comfortable on compromised skin. It tends to hold up better in dry indoor air, where hyaluronic acid alone can feel tight.

Is beta-glucan serum sticky?

It is thicker and slightly tacky going on, then settles once you follow with moisturizer. Applying it to damp skin and using less helps.

Can I use it with retinol or exfoliating acids?

Yes. Hydrating serums layer with actives without conflict, and many people use them to buffer retinol. Apply the active first, then the serum, unless your skin prefers the reverse.

Is it suitable for sensitive skin?

There are no exfoliating acids or high-percentage actives here, which makes it a reasonable pick for reactive skin. Patch test for a week if new products tend to bother you.
