Signal peptides: regulate cellular communication (such as growth hormone releasing peptides)^^ Antimicrobial peptides: inhibit pathogenic microorganisms (such as lactoferrin peptide) 5 Immune regulatory peptides: activate T cells, macrophages 5 Antioxidant peptides: eliminate free radicals and protect cells

Components that come into direct contact with materials should be made of 316L stainless steel or titanium to avoid metal ion contamination (such as copper peptide production requiring prevention of copper ion precipitation) The sealing material must comply with FDA/EU standards to prevent leakage caused by organic solvents or acid-base corrosion The surface needs to be electrolytic polished to reduce the risk of microbial growth (GMP requirement Ra ≤ 0.4 μ m)

Anti aging and firming: By stimulating the synthesis of collagen and elastin (such as palmitoyl tripeptide-1, pentapeptide-3 and other signaling peptides), it enhances skin support, improves sagging and wrinkles. For example, Heyi PQQ sturgeon caviar collagen tripeptide achieves contour support through a layered anti-aging system. Repair barrier: Small molecule peptides can quickly penetrate into the dermis layer, promote epidermal cell regeneration, and repair micro injuries caused by photodamage or medical aesthetics. Clinical studies have shown that it can accelerate wound healing.

Injectable peptides, such as ticagrelor peptide and marsupide, can suppress appetite or delay gastric emptying by regulating GLP-1 receptors, but may cause side effects such as gastrointestinal discomfort, allergies, or endocrine disorders. Oral/patch type: such as Lin Shi Ma Shi Du Peptide, Lu Jiao Hui Qing Zhi Tie, etc. Some products combine "Japanese imported technology" promotion, but the actual effect and safety need to be carefully evaluated.
