Is your skin lacking moisture? You've probably heard of hyaluronic acid, a star among skincare ingredients, but have you also heard of beta-glucans? Which ingredient is right for what you're looking for? Here, we explain everything about these two miracle ingredients with hydrating properties.
Beta-glucans and hyaluronic acid are both highly effective moisturizing ingredients, but they differ in their chemical structure, mechanism of action, and specific skin benefits. Here's a look at how they differ when it comes to moisturizing:
Hydration mechanism:
-
Beta-glucans:
- Deep and long-lasting hydration : They attract water into the skin, but they also form a protective barrier which prevents dehydration.
- Soothing action : Ideal for sensitive or irritated skin thanks to their ability to reduce inflammation and strengthen the skin barrier.
- Able to penetrate into the surface layers to improve skin texture and resilience.
-
Hyaluronic acid :
- Intense and immediate hydration : Hyaluronic acid acts like a sponge, retaining up to 1,000 times its weight in water , which gives a visible rebound effect.
- Low molecular weight forms: Penetrate deeper into the skin to hydrate the lower layers .
- High molecular weight forms: Remain on the surface to create a moisturizing layer.
- -> It is therefore advisable to mix or vary the molecular forms of hyaluronic acid to obtain optimal hydration ✨
Targeted skin types:
-
Beta-glucans:
- Perfect for the sensitive, irritated or stressed skin .
- Suitable for dry to normal skin who need hydration sustainable with a restorative effect.
-
Hyaluronic acid :
- Suitable for all skin types, especially dehydrated or aging skin .
- Offer a immediate rebound effect, particularly visible on tired or lacking firmness skin.
Durability of the moisturizing effect:
- Beta-glucans: Hydration is more sustainable thanks to their ability to retain moisture while strengthening the skin barrier.
-
Hyaluronic acid : The moisturizing effect is more fast , but can fade if the skin barrier is not well maintained.
-
- -> These two ingredients work wonders together!
-
Additional properties:
-
Beta-glucans:
- Repairs damaged skin.
- Soothe and reduce inflammation.
- Boost cell renewal and collagen production.
-
Hyaluronic acid :
- Instantly plumps.
- Promotes healing of small lesions.
- Protects against environmental aggressions through its antioxidant action.
For optimal hydration, many products combine the two ingredients to benefit from both their immediate effects and their long-lasting hydration!
