Eau Thermale Avène Vitamin Activ Cg Radiance Concentrated Serum — Vitamin Cg, Niacinamide & Bakuchiol, lightweight brightener

Eau Thermale Avène Vitamin Activ Cg Radiance Concentrated Serum is a lightweight brightening serum that combines stabilized Vitamin Cg, niacinamide and bakuchiol to boost radiance and help reduce the look of dark spots and fine lines.

Designed by Avène's dermatological research team, this concentrated serum blends a highly stable form of vitamin C (Pro-Vitamin Cg), niacinamide and bakuchiol in a hydrating base to improve skin tone and surface texture. The formula favors high sensory appeal—absorbing quickly without greasy residue—and is made with a high proportion of natural-origin ingredients and sustainable packaging. It aims to visibly enhance luminosity and evenness over weeks of regular use while providing antioxidant support for everyday skin stressors.

How quickly will I notice brighter-looking skin?

Users typically see an immediate improvement in surface radiance thanks to the serum’s illuminating base and stabilized vitamin C derivative. Continued nightly or twice-daily use supports more noticeable evening of skin tone within weeks as the active trio works to reduce the visual appearance of discoloration and dullness.

• Instant glow from light-reflecting, non-greasy texture
• Pro-Vitamin Cg provides antioxidant brightening effects
• Visible toning improvements commonly reported within 1 month

What active ingredients are included and what do they do?

The serum pairs three targeted actives: Avène’s ultra-optimized Vitamin Cg (ascorbyl glucoside), niacinamide and bakuchiol. Each component contributes a different benefit—brightening and antioxidant protection from Vitamin Cg, barrier and tone support from niacinamide, and retinol-like smoothing from bakuchiol without typical irritation.

• Vitamin Cg (stable ascorbyl glucoside) — concentrated, antioxidant brightening equivalent to a higher percentage of pure vitamin C
• Niacinamide — helps refine texture and improve evenness
• Bakuchiol — supports the appearance of smoother skin and reduced fine lines

Will this serum feel heavy or leave a residue under makeup?

The formula is intentionally lightweight with high sensory appeal so it absorbs quickly and layers well beneath moisturizers and makeup. Because it does not leave a sticky film, it suits morning routines when followed by SPF and makeup application.

• Rapid absorption for easy layering
• Non-greasy finish compatible with daily SPF and base makeup
• Hydrating base to avoid tightness while delivering actives

Are there any sustainability or formulation details I should know?

Eau Thermale Avène emphasizes ingredient stability and a high proportion of natural-origin components, and the product is packaged with sustainability considerations. The concentrated approach uses optimized active delivery so you get strong efficacy with thoughtful sourcing.

• Approximately 94% ingredients from natural origin
• Stable Pro-Vitamin Cg minimizes oxidation compared with pure vitamin C
• Sustainable packaging supports reduced environmental impact

Who is this for: This serum is intended for people seeking a radiance-boosting, non-irritating daily treatment to even skin tone, reduce the visible appearance of dark spots and fine lines, and add antioxidant protection. It is suitable for most skin types that tolerate active ingredients, especially those looking for a stabilized vitamin C alternative to traditional ascorbic acid, and for anyone preferring a lightweight texture that layers easily into morning or evening routines. If you have particularly sensitive skin or are using prescription retinoids, consider patch testing or consulting a skincare professional before integrating new actives.
