How Vitamin C Complex Works

Tetrahexyldecyl Ascorbate:
Brightening & Collagen Support
Tetrahexyldecyl Ascorbate is a stable, oil-soluble form of vitamin C that penetrates deeply into the skin. It supports collagen production while helping brighten uneven skin tone, improve radiance and contribute to firmer, healthier looking skin over time.

Antioxidant Protection:
Defence Against Environmental Stress
Antioxidants help protect the skin from free radical damage caused by environmental stressors such as pollution and UV exposure. By reducing oxidative stress, they help maintain skin health while supporting a brighter, clearer and more resilient complexion.

Skin Brightening Support:
Improving Tone & Clarity
Brightening actives help reduce dullness and uneven skin tone by supporting a more balanced skin appearance. By improving clarity and radiance, they help the skin appear more even, refreshed and visibly healthier over time.

Hydration & Barrier Support:
Skin Comfort & Balance
Supporting ingredients help maintain hydration and reinforce the skin barrier. This helps improve skin comfort and ensures active ingredients remain effective, leaving the skin feeling smoother, more balanced and better able to maintain overall skin health.
