FAQ
What makes Skin Diligent Vitamin C Serum unique?
Our serum uses an advanced fat-soluble form of vitamin C (Ascorbyl Tetraisopalmitate), known for its superior stability, optimal absorption rate, and ability to penetrate deeply without requiring an acidic pH. Combined with biomimetic actives, it maximizes antioxidant efficacy and collagen stimulation without causing irritation or premature oxidation.
I've used high-end Vitamin C serums before. Will I see a difference?
Yes. Unlike traditional forms of water-soluble vitamin C (such as ascorbic acid), our serum ensures more efficient cellular absorption and better skin tolerance. Many users who have tried other products have noticed the difference.
Is it suitable for sensitive skin?
Yes, our epigenetic formulation was developed to deliver high efficacy while respecting skin integrity. Ascorbyl Tetraisopalmitate does not require an acidic environment to be activated, reducing the risk of irritation often associated with traditional Vitamin C. In addition, our complex of natural omegas and antioxidants strengthens the skin barrier, protecting the skin from environmental aggressors while soothing sensitivities.
What are the benefits of vitamin C for the skin?
Vitamin C is a powerful antioxidant that protects the skin from oxidative stress caused by free radicals and external aggressions (UV rays, pollution). It stimulates collagen production, thus improving the skin's firmness and elasticity. It also helps reduce pigmentation spots, even out skin tone, and boost radiance.
