Research published in the Journal of Cosmetic Dermatology validates the formulation approach used by Senté Labs, demonstrating that the combination of heparan sulfate analog (HSA) and tetrahexyldecyl (THD) ascorbate in Defense C Serum significantly reduces oxidative stress and DNA damage while enhancing skin clarity, brightness, and texture without irritation.

The study, titled "Specific Stacking of Key Molecules to Enhance Skin Care Outcomes: Synergistic Effects of Heparan Sulfate Analog and Tetrahexyldecyl Ascorbate Combination," was published in 2026 and authored by Vivian Bucay, MD; Rosalyn George, MD; Anna Guiotto, PhD; Alessandra Pecorelli, PhD; Emmanuel Ike; and Angel S. Byrd, MD, from Howard University College of Medicine.
Senté's Defense C Serum effectively pairs HSA with THD ascorbate, a stable form of vitamin C known for boosting collagen production. Instead of merely increasing ingredient concentrations, the researchers explored the effects of combining HSA’s regenerative properties with THD ascorbate. This approach, termed "bioactive stacking," produced impressive results.
Since its launch in September 2025, the Defense C Serum has quickly become a top-selling product for Senté. The peer-reviewed validation enhances its credibility, providing evidence for practitioners who have observed positive outcomes in their patients.
In laboratory tests involving UV-damaged human skin, the HSA-THD combination demonstrated significant protective effects. A single application resulted in a 44% reduction in a key oxidative stress marker within 24 hours, along with a 9.5% reduction in DNA damage and a 37% decrease in aging markers (AGEs).
The clinical study also reported remarkable visible results over 12 weeks. By Week 8, participants observed a 38% improvement in skin clarity, a 41% increase in brightness and luminosity, a 47% enhancement in texture and smoothness, a 35% overall reduction in photodamage, and a 46% improvement in fine lines and wrinkles.
The study's findings were overwhelmingly positive, with 94% of participants noting brighter skin, 88% reporting clearer skin, 87% experiencing smoother texture, and 81% indicating measurable improvement in photodamage. Importantly, 100% of participants reported satisfaction with their results, while all reported no irritation or redness after four weeks of use.
Zubin Meshginpoosh, CEO of Senté Labs, commented on the study, stating, "This study confirms what we've long believed: more actives don't automatically mean better outcomes. By pairing ingredients with independent, complementary mechanisms of action, we optimized both the delivery and tolerability of vitamin C, enabling patients to achieve visible results without the irritation often associated with high-performance actives."
This research adds significant evidence to the efficacy of Senté’s heparan sulfate technology, reinforcing the company’s philosophy that thoughtful formulation leads to better patient outcomes. Senté Labs specializes in medical-grade skincare products, focusing on restoring the skin's microenvironment and supporting long-term skin health.
