The core ingredient — Nano-Glutathione — is engineered to be significantly smaller (6024x) than a human pore and has demonstrated in testing to be twice as effective as [Vitamin C at addressing surface discoloration](https://www.trendhunter.com/trends/hyper-c-serum). The serum is powered by additional ingredients like Niacinamide, Vitamin C, Arbutin, Kojic Acid, and N-Acetyl Glucosamine, while the patches boast Niacinamide (Vitamin B3), N-Acetyl Glucosamine (NAG), Panthenol and Ceramides. The serum alone has shown up to a nearly 22% improvement in surface pigmentation compared to just over 10% for Vitamin C over the same period.
