Eau Thermale Avène Vitamin Activ Cg Brightening Serum, Vitamin C + Niacinamide — 1 fl oz, Bakuchiol

Avène Vitamin Activ Cg Brightening Serum is a lightweight, dermatologist-tested radiance serum that combines ultra-optimized Vitamin Cg, niacinamide and bakuchiol to visibly even tone, smooth fine lines and boost glow.

This concentrated 1 fl oz serum from Eau Thermale Avène is formulated to deliver a multi-action brightening and smoothing effect while remaining suitable for sensitive skin. By using a stable pro-vitamin Cg (Ascorbyl Glucoside) that acts like high-dose vitamin C, together with niacinamide and bakuchiol, the formula aims to lift dullness, reduce the look of dark spots, and refine texture without leaving a greasy finish. The lightweight texture absorbs quickly, making it simple to layer under moisturizers and sunscreen.

How does this serum brighten and even skin tone?

The serum relies on Avène’s Ultra-Optimized Vitamin Cg, a stable ascorbyl glucoside that delivers antioxidant activity comparable to a 20% vitamin C effect while reducing typical instability of pure vitamin C. Niacinamide complements it by targeting uneven tone and barrier support, helping skin appear more uniform and luminous over time.

• Pro-vitamin Cg: provides stabilized brightening action.
• 3% Niacinamide: supports even tone and skin texture.
• Antioxidant blend: defends against environmental dulling factors.

Will this serum help reduce the look of fine lines and texture?

Yes — the combination of ingredients targets visible signs of aging and texture. Bakuchiol, a botanical alternative to retinoids, helps promote the appearance of smoother skin while niacinamide supports barrier function and overall texture improvement. Regular use typically shows visible smoothing within weeks for many users.

• 1.5% Bakuchiol: supports smoother-looking skin and refined texture.
• Lightweight base: layers easily without pilling under creams or makeup.
• Derm-tested: developed for compatibility with sensitive skin types.

How should I incorporate this serum into my daily skincare routine?

Apply a few drops to clean, dry skin once daily, preferably in the morning to take advantage of antioxidant protection, or at night if preferred. Follow with a moisturizer and broad-spectrum sunscreen in the morning; at night pair with a hydrating cream. Because the formula is lightweight and non-greasy, it fits smoothly into most routines.

• Use on cleansed skin: apply 2–4 drops to face and neck.
• Layering: follow with moisturizer; sunscreen is essential daytime.
• Sensitivity tip: introduce gradually if you have reactive skin.

What makes this Avène serum suitable for sensitive skin?

Eau Thermale Avène formulates this serum with dermatological testing and a high proportion of natural-origin ingredients to reduce irritation risk while keeping efficacy. The stabilized vitamin C form and gentle botanical bakuchiol were chosen to offer brightening and smoothing benefits with improved tolerance versus some traditional actives.

• Dermatologically tested on sensitive skin for compatibility.
• 94% natural-origin ingredients and mindful packaging choices.
• Non-greasy, high sensory appeal for comfortable daily wear.
