Beta-Glucan and Oat: Deep Comfort for Thirsty Skin

If hyaluronic acid has ever felt too light for your skin, beta-glucan might be what you've been missing.

What is beta-glucan?

Beta-glucan is a natural sugar found in oats, mushrooms and yeast. In skincare it holds moisture and comforts skin. Oat (Avena sativa) extract, which contains beta-glucan, is one of the best-known soothing ingredients for dry, itchy skin.

What it does for your skin

• Hydrates. It draws in moisture and helps skin feel plump.
• Soothes. It comforts dry, itchy-feeling or irritated skin.
• Supports the barrier. Skin feels more resilient over time.

Who it suits

Dry, sensitive and redness-prone skin. Great for winter or after too much sun.

How to use it

1. Use in a serum or gel cream after toner.
2. Layer under a richer cream if your skin is very dry.
3. Morning and night.

When you'll notice it: Skin feels comfortable straight away.

Good to know: Very gentle. If you're sensitive to oats, patch-test first.

What to pair it with

Beta-glucan pairs well with panthenol, ceramides and cica.

Myth vs fact
