Key FeaturesPatented Advanced Transdermal Delivery System
Backed by U.S. Patent No. 6,645,508 B1 and International Patent WO/0078283 A1, this proprietary system enhances absorption into both hydrophilic and lipophilic skin layers, maximizing ingredient efficacy.
25% Pure L-Ascorbic Acid
A clinically potent concentration that brightens, firms, and revitalizes the complexion.
Exceptional Vitamin C Stability
Maintains over 88.5% potency after 30 months, thanks to a water-free formulation that resists oxidation.
Stability Test
Clinical evaluations demonstrate changes in vitamin C content and the degree of browning after extended storage.
Any shift toward yellow or brown coloration, caused by oxidation, is known as browning. The more pronounced the color change, the greater the oxidation that has occurred.
As a result, vitamin C products exhibiting significant browning can no longer be expected to deliver optimal efficacy.
Other vitamin C serums that use water as a solvent exhibit a dramatic decrease in vitamin C content and significant color change due to oxidation, even over a short storage period.
In contrast, C’ENSIL maintains a remarkably high vitamin C concentration with minimal color change, even after 30 months of storage.
Clean, High-Purity Formula
Free from water, alcohol, and preservatives to ensure optimal compatibility and minimal irritation.
