Our SerumC contains 12% L-ascorbic acid (vitamin C), a powerful antioxidant that also helps increase collagen production. This product is especially beneficial for clients with sallow, lackluster skin—such as those who are very dehydrated, smokers, or former smokers. With its slightly heavier consistency, this serum is also excellent for clients seeking a richer night regimen.
SerumC delivers results that will transform the tone and texture of the facial and neck skin. Results you can expect include:
- Increased collagen growth
- Reduction in fine lines and wrinkles
- More even skin tone
- Improved skin firmness
- A healthy, radiant glow
Unlike typical vitamin C products that are unstable and often turn brown or black within months (losing potency once oxidized), SerumC is uniquely formulated to maintain its effectiveness. It has a two-year shelf life, ensuring a true 12% concentration from the moment you purchase it until the last drop is used. SerumC delivers 20–40 times more vitamin C than what can be absorbed through supplements, proving that topical application is the most effective method for skin rejuvenation.
This product should be used in conjunction with your regular moisturizer by layering the two. Layering is a popular and effective technique for achieving multiple benefits in your daily skin care regimen.
