For many sensitive skin types, each new serum feels like a test. Hyaluronic acid that tightens, vitamin C that heats, superimposed layers of active ingredients to track down fine lines: after a while, the epidermis says stop. And there, even treatments deemed gentle are no longer really enough to soothe.
In this context comes a still discreet active ingredient: beta-glucan. Coming from oats or certain yeasts, this polysaccharide is both hydrating and anti-inflammatory. More soothing, more restorative, sometimes presented as more effective than hyaluronic acid, it now attracts reactive skin looking for lasting hydration.
When hyaluronic acid is no longer enough for sensitive skin
Tightness, redness, tingling after even the slightest “active” cream: this picture speaks to many people. Hyaluronic acid remains a reference for plumping, with a rapid effect. But on skin already irritated by acids, retinol or ambitious routines, it is not always enough to break the dehydration plus inflammation circle.
This is where beta-glucan stands out. Rather than acting only as a water sponge, it strengthens the skin barrier and helps the skin defend itself better. It retains more moisture, reacts less violently to external aggressions and little by little comes out of the skin pattern that itches, then is overloaded with care to calm it down.
Beta-glucan: an anti-inflammatory polysaccharide that repairs
Chemically, beta-glucan is a complex sugar found in oats and some yeasts. Its particularity lies in its ability to interact with skin cells. Dermatologist Gabriela Arana sums it up: , she explains during an exchange with the magazine.
On the skin, this action results in deeper and more stable hydration. Where hyaluronic acid provides an immediate but sometimes fleeting boost of freshness, beta-glucan forms a light film which limits water loss, supports the repair of the skin barrier and also contributes to better firmness by stimulating the renewal mechanisms.
How to include beta-glucan in a routine for sensitive skin
In practice, we find beta-glucan in serums, “barrier” creams or post-treatment care, often associated with ceramides or hyaluronic acid. Its very good tolerance makes it an interesting candidate for sensitive, intolerant skin or skin weakened by overly exfoliating routines, which need care that is both moisturizing and soothing.
The ideal procedure remains simple: after a gentle cleanser, apply a beta-glucan treatment to clean skin, before a cream and sun protection in the morning. In the evening, it can be used alone on days when the skin is heated, or as a “soft” layer after stronger active ingredients, to gradually calm feelings of discomfort.
Does beta-glucan hydrate better than hyaluronic acid?
Beta-glucan hydrates as much as hyaluronic acid, but more consistently, while helping the skin barrier to remain intact.
For which skin type should you choose beta-glucan?
It is especially suitable for sensitive or reactive skin, dried out by acids, retinol or treatments that irritate easily.
Can it be combined with hyaluronic acid?
Yes, the two complement each other very well and can be layered in the same routine, morning or evening.
