Products Description

Pentapeptide-3 Powder is an artificially synthesized five-amino-acid active oligopeptide. It is also a classic dual-function signaling peptide and neuroregulatory peptide in the field of anti-aging cosmetics. It has a fixed and precise amino acid sequence, a stable molecular structure, and a molecular weight that is suitable for the absorption of the skin within the golden range. It neither rapidly metabolizes due to its small molecules nor fails to penetrate the stratum corneum due to its large molecules. In an environment of constant temperature and dryness, Pentapeptide-3 Powder is a fine white crystalline powder. Its powder texture is uniform, fine, and dry, and it has excellent odor properties. In its high-purity powder state, it only has a very faint micro-odor of the peptide itself, without any pungent chemical smell. Pentapeptide-3 Powder has excellent dissolution performance and belongs to highly hydrophilic active oligopeptides. At normal temperature and pressure, the high-purity powder can quickly dissolve in mainstream water-phase solvents such as pure water, glycerin, and propylene glycol, and can be completely dissolved with a slight stir.

Products function

Pentapeptide-3 can gently block the nerve-muscle conduction signals on the skin's surface, effectively reducing the pulling sensation caused by the frequent contraction of facial muscles, and fundamentally improving and preventing the formation of dynamic wrinkles. It has a very good soothing and improving effect on frown lines, forehead wrinkles and glabella wrinkles caused by daily expressions.

Pentapeptide-3 can precisely activate the activity of dermal fibroblasts, effectively promoting the autonomous synthesis of type I and type III collagen as well as fibronectin, while moderately inhibiting the activity of collagen-degrading enzymes and reducing the loss of native collagen in the skin. It can gradually fill the collagen vacancies in the dermis, improving problems such as skin laxity and facial collapse caused by collagen loss.

Pentapeptide-3 can regulate disordered skin fibrous tissues, and improve common skin problems such as rough texture, unevenness, and dryness in mature skin. By consistently applying it, the overall skin texture can become smooth and fine, while maintaining the stability of skin collagen and delaying the aging process of the skin. It is not a temporary superficial modification effect, but a long-term improvement of skin texture and skin age.

Products Application

It is widely used in core products such as anti-aging essence, anti-wrinkle cream, firming lotion, and anti-aging serum.

Pentapeptide-3 can be used in anti-wrinkle eye creams, eye serums, eye masks, and other refined skincare products.

It can be added to anti-aging toners, repair lotions and creams, bare skin firming lotions, and daily stabilizing creams as basic skincare items.

Pentapeptide-3 is an excellent mild alternative ingredient. It can be used in anti-aging, repair and anti-wrinkle products specifically for sensitive skin.
