Lipid-soluble tetrahexyldecyl ascorbate penetrates deep dermal fibroblasts without low-pH stinging or auto-oxidative degradation.
We catalog the 15% Tetrahexyldecyl Ascorbate Lipid Vitamin C Complex as an inquiry-only clinical formulation for restorative surgical practices and specialized estheticians seeking non-acidic, oxidation-resistant active serum formulations.
Direct supply quotations range between 48 and 115 USD per package. Typical packaging format: 1 unit / individual package (30ml or 50ml UV-shielded amber glass vial). Final unit quotation depends strictly on brand lineage, volume or capsule count, botanical/dermatological active ingredient composition, formulation delivery vehicle, purchase point or site, and seasonal promotions or batch tier volume incentives.
Dermal penetration kinetics and metabolic activation
Traditional aqueous L-ascorbic acid suffers from two major clinical limitations: extreme chemical instability in water and poor trans-stratum-corneum bioavailability. Because native ascorbic acid is a small hydrophilic polyhydroxy molecule with a pKa of 4.2, it cannot cross the hydrophobic lipid bilayers of the stratum corneum unless formulated at an aggressive, irritative pH below 3.5. Even then, exposure to atmospheric oxygen or ambient light triggers auto-oxidation into dehydroascorbic acid and diketogulonic acid, turning aqueous serums brown and generating pro-oxidant free radicals on skin.
Tetrahexyldecyl ascorbate (THD ascorbate) overcomes both hurdles through synthetic structural engineering. Four lipophilic 2-hexyldecanoate branched chains are esterified to the ascorbic acid core. This tetra-ester architecture renders the molecule completely soluble in non-polar lipid matrices while rendering it neutral and stable against aqueous decomposition. When applied topically, the lipophilic chains merge smoothly with the intercellular lipid mortar, allowing intact molecules to traverse the stratum corneum and stratum spinosum down to viable dermal fibroblasts.
Once inside intracellular domains, endogenous esterase enzymes cleave the four fatty acid esters, liberating pure bio-active L-ascorbic acid directly at the site of procollagen hydroxylation and melanogenesis. Comparative clinical permeation assays demonstrate up to fifty-fold higher dermal penetration compared to free L-ascorbic acid, with zero risk of acid-induced stinging or cutaneous erythema.

Formulation verification and Austin desk supervision
Zenito Skin maintains an exacting curation protocol under the direction of Irina Petrova, Senior Product Manager, directing our catalog and stability evaluations since 2021. Zenito Skin operates from our facility at 308 Brazos Street in Austin, Texas, backed by Florida corporate legal registration and active membership in reputable industry cosmetic trade associations.
We operate exclusively on an inquiry-only catalog model. We do not provide self-service merchant shopping carts or automatic credit card transactions. Every batch inquiry receives a custom specification sheet and volume-adjusted procurement terms directly from our Austin team within four business hours.

Formulation limitations and contraindications
While THD ascorbate is exceptionally gentle compared to free ascorbic acid, our desk clearly defines non-suited applications. This lipid-soluble formula is suspended in squalane and is not recommended for patients suffering from active, severe pustular cystic acne where any supplemental lipid vehicle could feel heavy; such clients should start with our water-based 10% Niacinamide + 1% Zinc PCA Serum. Furthermore, patients undergoing active photodynamic chemical peeling should delay lipid antioxidant application until stratum corneum re-epithelialization is confirmed.
Clinics addressing structural dermal collapse or volumetric depletion should review our signaling Copper Tripeptide-1 + Matrixyl Serum or combine treatments with our 3:1:1 Ceramide Barrier Restorative Cream to establish complete moisture retention.
