Cosmetics formulated with NMN*3 using the latest*1 NtDDS technology*2. What is NtDDS? Our proprietary nano-dispersion penetration technology nano-encapsulates water-soluble and high-molecular-weight ingredients in an oil layer. Delivering ingredients deeper into the stratum corneum (stratum corneum) is nano-dispersed and reaches every corner of the stratum corneum. The skin's surface is highly hydrophobic, protecting it from dryness and external irritation, making it difficult for water-soluble ingredients to penetrate. However, the nano-dispersion penetration technology developed by NtDDS encapsulates water-soluble ingredients in nano-sized capsules and converts them into jojoba oil, which provides affinity to the hydrophobic skin surface, achieving excellent penetration and stability. We recommend using this product immediately after washing your face. This introductory oil combines NMN, vitamins, vitamin E, proteoglycans, and ceramides coated with NtDDS and oiled into jojoba oil. Jojoba oil blends easily into the skin, has a low stickiness, and is highly compatible with the skin surface. *1 Nano-dispersion penetration technology developed by the manufacturer *2 Proprietary technology *3 Nicotinamide mononucleotide (skin conditioning ingredient)
