Eau Thermale Avène Vitamin C Brightening Serum, 1 fl oz — Niacinamide & Bakuchiol for Even Tone and Radiance

Eau Thermale Avène Vitamin Activ Cg Brightening Serum is a lightweight radiance serum that combines a stable Pro‑Vitamin Cg equivalent to 20% vitamin C, 3% niacinamide and 1.5% bakuchiol to visibly even tone, smooth the look of fine lines and boost glow.

This concentrated serum was formulated to bring targeted brightening and smoothing benefits while remaining suitable for sensitive skin types. Avène’s Pro‑Vitamin Cg (ascorbyl glucoside) is designed to deliver antioxidant support and visible radiance without the instability of pure vitamin C, paired with niacinamide to even skin tone and bakuchiol as a plant‑derived retinol alternative. The texture is featherlight, fast‑absorbing and designed to leave skin luminous without a sticky residue.

How quickly will I notice brighter skin?

Many users report an immediate boost in luminosity thanks to the serum’s light‑reflecting and antioxidant components. Structural improvements in tone and the appearance of dark spots typically become more apparent with consistent use over several weeks.

• Instant: fresh, dewy surface glow after first applications
• Weeks: progressive reduction in the look of uneven tone and dark spots
• 1 month: visible smoothing of fine lines reported in clinical testing

Can sensitive skin tolerate this formula?

Avène developed this serum with dermatological testing on sensitive skin in mind, using a stabilized vitamin Cg form and a minimal‑irritation approach. The blend aims to provide brightening and smoothing benefits while keeping sensitization risk lower than some traditional high‑strength vitamin C formulas.

• Pro‑Vitamin Cg: stable, less irritating alternative to pure ascorbic acid
• Niacinamide: supports even tone and barrier comfort
• Lightweight base: absorbs quickly, avoids greasy film

How should I incorporate this serum into my routine?

Apply on clean, dry skin once or twice daily depending on tolerance, followed by moisturizer and sunscreen in the morning. Because it supports radiance and tone, it pairs well under SPF during daytime and under a nourishing cream at night.

• Step 1: cleanse and pat skin dry
• Step 2: dispense a few drops and smooth over face and neck
• Step 3: follow with moisturizer and morning SPF

What are the key ingredients and their roles?

The formula centers on a trio of clinically minded actives: an optimized vitamin C derivative, niacinamide and bakuchiol. Each ingredient contributes to brightness, tone correction and the appearance of smoother skin without relying on overly irritating concentrations.

• Pro‑Vitamin Cg (ascorbyl glucoside): antioxidant brightening equivalent to 20% vitamin C
• Niacinamide 3%: helps even pigmentation and supports barrier function
• Bakuchiol 1.5%: plant‑derived alternative linked to smoothing appearance

Features include a high‑sensory, lightweight texture, a formula made of approximately 94% ingredients from natural origin, and packaging designed with sustainability in mind. The product aims to provide visible radiance while minimizing residue and heaviness on the skin.

Who is this for? This serum is suited for people seeking a potent brightening and smoothing treatment that balances efficacy with tolerance for sensitive skin. It’s ideal for those who want antioxidant support, clearer‑looking tone and a non‑greasy finish—whether you’re introducing corrective actives to your regimen for the first time or layering targeted treatments under daily sunscreen and moisturizer.
