On April 9, physician‑dispensed medical‑grade skincare company, Revision Skincare, announced the publication of two peer‑reviewed clinical studies in the Journal of Cosmetic Dermatology, evaluating the cosmetic efficacy, tolerability and visible skin benefits of their C+ Correcting Complex 30% — a high‑strength vitamin C formulation featuring tetrahexyldecyl ascorbate (THD ascorbate).
The two peer‑reviewed studies demonstrated cosmetic benefits of the formula, add to the growing body of peer‑reviewed evidence supporting THD ascorbate as a stable, skin‑compatible vitamin C derivative used in advanced cosmetic skincare formulations.

"At Revision Skincare, clinical validation is foundational to how we prove our products' efficacy," said Dr. Alisar Zahr, vice president of research and clinical development at Revision Skincare. "The publication of these peer‑reviewed studies underscores our commitment to rigorous science and highlights the role of THD ascorbate within C+ Correcting Complex 30% as part of our evidence‑based approach to skincare innovation."
What Was Studied?
The published research focuses on a high‑concentration THD ascorbate formulation and its ability to visibly improve multiple markers of skin quality when used consistently as part of a topical skincare regimen.
THD ascorbate is a lipid‑soluble vitamin C derivative used in cosmetic science for its formulation stability and skin‑mimicking properties. Unlike traditional water‑soluble L‑ascorbic acid, THD ascorbate is designed to better associate with the skin's lipid matrix, supporting penetration into the epidermis and dermis and improved cosmetic bioavailability.
Across both studies, investigators reported:
- Visible improvement in overall skin appearance
- Increased skin radiance and brightness
- Improved tone evenness and surface texture
- Reduction in the visible appearance of photodamage and uneven pigmentation
- Demonstrated skin compatibility and cosmetic tolerability during regular use
Preclinical findings also demonstrated robust buffering of reactive oxygen species (ROS) induced by high‑energy visible (blue) light, as well as significant inhibition of melanogenesis and improvements in overall skin architecture, including the epidermis, dermal‑epidermal junction and dermis.

Together, these findings support the use of THD ascorbate as an effective vitamin C alternative, delivering visible cosmetic benefits while addressing common formulation, stability and tolerability challenges historically associated with high concentrations of L‑ascorbic acid.
