Our collagen skin maintenance liquids are specifically formulated for various skin types, including dedicated options for dry, oily, neutral, and mixed skin types, all designed to be safe for sensitive skin.
The aseptic type undergoes strict sterile processing keeping the colony count under ≤ 10CFU/g. The non-sterile type maintains a safe and standard cosmetic grade limit with a colony count under ≤ 100CFU/g.
The formulation utilizes recombinant Type III collagen, which has high biocompatibility and excellent skin penetration properties, helping to repair and soothe sensitive skin effectively.
Products are classified into maintenance levels based on performance indicators. For example, Premium Grade features a moisturizing index of ≥ 6, a water-locking index of ≥ 7, a nutrient penetration rate of ≥ 6, and an antioxidant index of ≥ 2.
No, our sensitive skin formulation relies on plant-derived preservatives like grapefruit peel extract, natural fungicides like coriander seed extract, and nourishing components like composite amino acids and olive oil base.
