With 25.5% stabilized L-ascorbic acid, C15+ Bioactive Concentrate is a high-potency antioxidant serum that is tailored in an anhydrous base for optimal skin tolerance, low oxidation, and maximum activity, even at professional strength.

With consistent usage, this cutting-edge product helps to improve skin resilience, firmness, and brightness. It was created to satisfy both the performance standards of in-clinic treatments and the convenience of use criteria for everyday at-home care.

The main component of C15+ is pure L-ascorbic acid, the most effective form of vitamin C that has been shown in studies to:

Eliminate oxidative stress and free radicals
Encourage the production of collagen and the healing of skin
Boost the brightness and homogeneity of skin tone

This water-free product contains the following buffers to help with the natural instability and discomfort that high concentrations of vitamin C can cause:

Betaine and Bisabolol to calm, hydrate, and reduce the risk of sensitivity
Multi-type collagen complex (soluble collagen, hydrolyzed collagen, atelocollagen) to reinforce the extracellular matrix
Centella Asiatica bioactives, including Madecassoside, Asiaticoside, and Asiatic Acid, to soothe inflammation, promote healing, and enhance barrier recovery
A peptide boost from Acetyl Hexapeptide-8 to support visible skin firmness and reduce signs of early aging

The inclusion of antioxidant-rich berry extracts (blueberry, raspberry, strawberry, and bilberry) further enhances the formula’s ability to combat environmental stressors and photoaging.

Since C15+ is stabilized without water or preservatives, unlike the majority of high-strength vitamin C serums, it is perfect for:

Clinical pre-treatment or post-laser recovery methods that require L-AA for antioxidant repair and collagen support
Use every day at home, particularly if you’re trying to combat aging symptoms, uneven tone, or dullness.

When used properly, its low pH and non-aqueous texture enable deep skin penetration while preserving an incredibly mild user experience, making it perfect for melanin-rich skin and conditions where the skin’s barrier is weakened.

Cleanse and tone your skin thoroughly. Ensure the skin is damp after toning.
Dispense 4–5 drops of C15+ Bioactive Concentrate onto your fingertips. This amount is sufficient for full face and neck coverage.
Gently apply to the face and neck using light, upward strokes or pressing motions. Avoid direct contact with the eyes or broken skin.
Allow the serum to absorb fully (1–2 minutes) before layering other hydrating treatments or moisturizers.
