I. Common types and their applications
1. Signal peptides
Representative peptides: A typical example is palmitoyl pentapeptide-4.
Mechanism of action: This substance can mimic the function of intercellular signaling molecules, activate skin cells, and promote the production of extracellular matrix such as collagen and elastic fibers, thereby enhancing skin tightness and elasticity, while reducing the formation of wrinkles.
Application effect: Continuous use of skin care products containing signal peptides can significantly reduce skin fine lines and wrinkles, and make skin stronger and more elastic.
2. Inhibitory neurotransmitter peptides
Representative peptides include acetyl-hexapeptide-8 and so on.
Mechanism of action: The drug mainly acts on the junction point between nerve and muscle, and reduces muscle contraction by inhibiting the release of neurotransmitters, thus effectively relieving dynamic wrinkles, such as crow’s feet and glabella lines.
Application effect: It can quickly and effectively reduce the wrinkles caused by facial expression muscle activity, and make the facial contour smoother.
3. Carrier peptide
Typical peptides include blue-copper peptides (i.e. copper glycinate) and so on.
Mechanism of action: It can effectively deliver some nutrients, such as copper ions, to skin cells, and then promote cell metabolism and repair. At the same time, it can also stimulate skin cells to synthesize growth factors, thereby enhancing the skin’s self-repair ability and improving the texture and color of the skin.
Application effect: CAN effectively improve the skin dark and rough and other problems, make the skin more smooth and delicate, show a healthy luster.
Second, the advantage of the role
High safety: many peptides in cosmetics are composed of natural amino acids, whose structure is similar to the biological molecules of the human body itself, with excellent biocompatibility. They usually do not cause allergic reactions or other serious side effects, and are suitable for people with all types of skin.
Highly targeted: Different peptides have their own unique targets and effects. According to the specific problems of the skin, such as wrinkles, laxity and dryness, the corresponding peptides can be selected for targeted care to achieve the effect of precise skin care.
Mild and long-lasting effects: Compared with some traditional skin care ingredients, peptides have a milder effect and are less likely to cause skin irritation. At the same time, it can regulate the physiological function of the skin from the cellular level. After long-term use, it can continuously improve the condition of the skin and help to keep the skin healthy and young.
3. Application status
Anti-wrinkle skin care: Peptides are often used as ingredients in anti-wrinkle skin care products, such as peptide serums and anti-wrinkle creams. The peptides in these products penetrate deep into the skin and promote the production of collagen, which in turn reduces wrinkles and makes the skin more firm and smooth.
Whitening products: Some peptides can inhibit the activity of tyrosinase and reduce the production of melanin, so as to achieve the effect of whitening and removing spots. Adding peptides to products such as whitening serums and flawless creams can effectively improve uneven skin tone, fade spots, and make skin smoother and whiter.
Reparative skin care products: For skin barrier damage and sensitive skin problems, skin care products containing reparative peptides can promote the repair and regeneration of skin cells, enhance skin barrier function, relieve sensitive symptoms, and help skin restore to a healthy state.
