Luxuriously formulated with high-penetration Vitamin C derivative, a new amphiphilic Vitamin C derivative, Vitamin B3 (niacinamide), Vitamin E derivative, and fullerene. Through a special manufacturing process, a Vitamin A derivative is encapsulated within a nano-capsule of the new amphiphilic Vitamin C derivative and Vitamin E to enhance penetration. Using hot spring water from Kagoshima as a base, it promotes skin metabolism and effectively delivers the beneficial ingredients to the stratum corneum. This was an expensive serum, but unfortunately, it didn't agree with my skin, so I'm reluctantly selling it. I've only used it once, so it's hardly been used. *Please check the remaining amount in the 4th image. Instant purchase is welcome. Thank you.
