1. PCL (Polycaprolactone) PCL particles can stimulate fibroblasts to promote collagen synthesis and regeneration. The skin restores its original elasticity and the compound also promotes the regeneration of the collagen filled protein, so the effect lasts longer. Collagen is a protein found mainly in the dermis of the skin. It plays an important role in keeping skin elastic and moisturizing. When collagen is deficient or damaged, skin loses elasticity and becomes thinner. 2. IntoCell growth factor FILLOUP contains IntoCell- growth factor, which is different from existing natural growth factors. Compared with primitive growth factor, IntoCell- growth factor showed excellent skin cell permeability. Core technologies are currently listed for the first time in the International Dictionary of Cosmetic Ingredients (ICID). In combination with fibroblast growth factor, epidermal growth factor, and keratinocyte growth factor, It boosts metabolism, increases the vitality of skin cells, and repairs the damaged skin barrier. 3. Peptides, Peptides complex Biomimetic peptides are low molecular biomaterials composed of amino acids and are the next generation of bioactive substances with high activity and safety. Its small molecular structure allows it to penetrate easily into the skin and helps in the synthesis of collagen and elastin. Copper tripeptide-1 can eliminate damaged collagen and elastin, inhibit scar, reduce inflammation and repair, and help skin regeneration. Acetyl Hexapeptid-8 is widely used to inhibit the effects of acetylcholine secretion, such as botulinum toxin. Enhances skin barrier and improves skin quality. 4. Hyaluronic acid Hyaluronic acid is the ideal natural moisturizing factor, it can store more than 1000 times its own weight of water, excellent moisturizing ability, can make the skin shine and elasticity. Use in combination with other nutrients to promote better nutritional absorption. 5. Glutathione Glutathione, commonly known as the whitening injectable ingredient, reduces melanosis in the skin. Still can prevent skin aging and pigmentation, reduce the formation of melanin, improve skin antioxidant ability and make the skin produce luster. At the same time, it can purify the internal environment, remove free radicals and delay the aging of skin. Amino acids, Minerals and Vitamins FILLOUP contains nucleic acids, coenzymes, amino acids, vitamins and minerals to provide an optimal environment for skin cells. Provide rich nutrition and appropriate pH concentration, osmotic pressure, etc., to create a healthy skin cell growth environment, so that skin cells grow well. At the same time can stimulate collagen and elastic fiber regeneration, restore skin elasticity.
