THDA stimulates collagen biosynthesis and inhibits melanogenesis to promote skin clarity and an even tone. Unlike pure ascorbic acid, it does not cause irritation or exfoliation. Its lipophilic structure allows deeper skin penetration for enhanced delivery of active vitamin C released enzymatically. It also protects skin lipids from free radical damage when paired with vitamin E. The recommended usage level is 0.1-2% for daily antioxidant protection and over 5% for targeting stubborn hyperpigmentation and melasma.


Although ATIP and THDA are both lipid-soluble forms of vitamin C, they are different compounds. While their molecular weights are the same, their chemical structures differ slightly. ATIP is more expensive and difficult to synthesize. It may also have different skin penetration abilities compared to THDA. Additionally, ATIP has extensive efficacy data showing significant effects even at low usage levels, while THDA is less researched. In summary, ATIP and THDA have their own characteristics as oil-soluble forms of vitamin C.
