In the research
24 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- Clinical Applications of Vitamin C in Dermatology: A Systematic Review · The Journal of clinical and aesthetic dermatology, 2026
- [Determination of six whitening ingredients in cosmetics by ultra performance liquid chromatography coupled with photodiode array detector and corona charged aerosol detector] · Se pu = Chinese journal of chromatography, 2026
- The Combination of Pterocarpus marsupium Bark Extract, Pinus strobus Bark Extract, and Ascorbyl Tetraisopalmitate Inhibits Melanogenesis via Nicotinamide Nucleotide Transhydrogenas · Journal of cosmetic dermatology, 2025
