What Thalgo Says
Product Description:
Thalgo Intense Moisture Quenching Serum is a highly concentrated serum that instantly quenches and boosts the skin's hydration. Its formula contains sève bleue des océans, a marine ingredient that has triple hydrating power, and revitalising Micronised Marine Algae Filtrate. The serum is enriched with Mediterranean padina extract, which reinforces the cohesion of the epidermal cells, limits the loss of water and minerals, and activates the diffusion of water and micronutrients through the different layers of the epidermis. This serum has a fresh, light texture with marine notes that quench the epidermis' thirst, leaving the skin in top form and glowing with beauty. Its pump cap delivers just the right dose, and to stimulate skin cells, tap lightly in upward movements from the central ridge of the face in an outward direction. Thalgo Intense Moisture Quenching Serum is gentle on the skin, with 90% natural-origin ingredients and no controversial substances. Its packaging is eco-friendly, with a recyclable pack made from eco-managed forests with plant-based inks and solvent-free varnishes.

Beta-glucan
Common Name(s): Beta-1,3/1,6-glucan,yeast beta-glucan,oat beta-glucan
CAS Number: 9041-22-9
DESCRIPTION
What It Does: Reduces inflammation, deeply hydrates, stimulates collagen synthesis, accelerates wound healing.
Why It's Used: Used in anti-aging, sensitive skin, post-procedure, and eczema care for multi-action anti-inflammatory, moisturizing, and regenerative benefits.
How It Works: Binds to dectin-1 and cr3 receptors on macrophages and keratinocytes activating tgf-beta and collagen synthesis pathways. also activates macrophage phagocytosis for wound healing. humectant from polysaccharide hydroxyl groups.
Typically Found In: Anti-aging serums,sensitive skin products,post-procedure care,eczema treatments
TECHNICAL DETAILS
Primary Category: Active ingredient – polysaccharide / immunomodulator
Secondary Functions: Immunomodulator,wound healing,collagen stimulation
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–5%
SOURCING & ETHICS
Vegan Status: Yes – yeast or oat-derived
Halal Status: Yes
Source Notes: Derived from saccharomyces cerevisiae yeast (1,3/1,6-linked) or avena sativa oats (1,3/1,4-linked). molecular weight affects penetration – lower mw for skin penetration vs high mw for surface hydration.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Non-irritating; ideal for reactive and sensitive skin.
Safe for Sensitive Skin: Yes – particularly recommended for sensitive skin
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,panthenol,allantoin,hyaluronic acid,centella asiatica
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Yeast beta-1,3/1,6-glucan receptor binding to dectin-1 on keratinocytes activates tgf-beta1, the key pro-collagen cytokine, stimulating fibroblast collagen production. this makes beta-glucan one of the few non-retinoid, non-peptide ingredients with direct receptor-mediated collagen stimulation.
