Ascorbyl Tetraisopalmitate (VC-IP)｜HerbBB ingredient encyclopedia

Why supplement?

✓

Maintains epidermal antioxidant protection

Four isopalmitate groups attach to ascorbic acid; the molecule becomes highly lipophilic and can dissolve into oil esters and the sebum film. Esterase stepwise hydrolysis uncovers the vitamin C backbone. An oil-phase carrier lets it stay longer at the junction of stratum corneum and living epidermis; photo-oxidation trials often use this tetraester.

✓

Evens skin tone

After hydrolysis it still takes ascorbic acid's collagen-hydroxylation and melanin-reduction paths. Oil-soluble formulas are common in creams or essence oils, with a richer feel. Human observations sit mostly in spots and the look of photodamage; people with oilier sebum feel the oil film linger longer, matching the moist film of an oil-phase serum.
