Acetyl octapeptide-1 can be used in research on muscle contraction and skincare products.

Palmitoyl tripeptide-38 is a lipopeptide that increases the production of dermal and epidermal collagen, fibronectin, and hyaluronic acid. Palmitoyl tripeptide-38 is used in research related to skin aging (fine lines, wrinkles, reduced skin elasticity, decreased skin water content, uneven skin tone).

Hexapeptide-12isa bioactive peptide with anti-aging effect and has been reported used as a cosmetic ingredient.

Palmitoyl tetrapeptide-10 is a bioactive peptide. Palmitoyl tetrapeptide-10 works synergistically with other active ingredients to increase the expression of corneodesmosin (a marker of keratinocyte adhesion) and filaggrin (a marker of keratinocyte terminal differentiation), thereby reducing skin permeability and improving skin barrier function. Palmitoyl tetrapeptide-10 can be used in the research of sensitive skin syndrome and skin pigmentation.

Oligopeptide-10 is a bioactive peptide with antimicrobial activity. Oligopeptide-10 exhibits broad-spectrum bactericidal effects against Gram-positive bacteria including Propionibacterium acnes and Staphylococcus aureus. Oligopeptide-10 targets lipoteichoic acid (LTA) on the surface of bacterial cell membranes, induces bacterial osmotic imbalance by disrupting the integrity of bacterial membranes, and reduces the release of pro-inflammatory cytokines induced by bacteria. Oligopeptide-10 possesses skin-protective activity. Oligopeptide-10 can be applied in research related to acne vulgaris, dandruff, seborrheic dermatitis, and tinea pedis.

Octapeptide-2 is a biomimetic peptide that mimics the thymosin-β4 growth factor. Octapeptide-2 can promote hair growth, reduce cell apoptosis, and increase the proliferation of keratinocytes. Octapeptide-2 can be used in the research of hair loss and alopecia areata.

Acetyl hexapeptide-37 is a bioactive peptide with anti-aging effect and has been reported used as a cosmetic ingredient.

Palmitoyl tetrapeptide-20 (PTP20) TFA is a biomimetic peptide agonist of α-MSH. Palmitoyl tetrapeptide-20 TFA promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC₅₀: 0.16 nM), enhancing catalase activity to reduce H₂O₂ accumulation, and upregulating SIRT1 activity. Palmitoyl tetrapeptide-20 TFA can be used in research on preventing hair loss and improving hair graying.

SA1-III(KP1) is a bioactive peptide withanti-agingeffect and has been reported used as a cosmetic ingredient.

Palmitoyl tripeptide-5 is a bioactive peptide with anti-aging effect and has been reported used as a cosmetic ingredient.

Acetyl hexapeptide-49 (example 13) is a bioactive peptide with anti-allergen effect and has been reported used as a cosmetic ingredient. Acetyl hexapeptide-49 can alleviate stimulation of mammalian skin cells and protect cell vitality.

Ac-Decapeptide is a bioactive peptide with anti-aging effect and has been reported used as a cosmetic ingredient.

Tetrapeptide-4 is a synthetic tetrapeptide. Tetrapeptide-4 upregulates hyaluronic acid synthetase, and collagen production in human dermal fibroblasts. Tetrapeptide-4 reduces skin aging, improves skin firmness, elasticity, and appearance, and benefits hair.

Acetyl tetrapeptide-15 is a synthetic peptide. Acetyl tetrapeptide-15 is derived from endomorphin-2 (Tyr-Pro-Phe-Phe-NH2), a human μ-opioid agonist with selective anti-nociceptive effect. Acetyl tetrapeptide-15 reduces skin hyperreactivity producing inflammatory, chronic and neuropathic pain, by increasing the threshold of neuronal excitability in μ-opioid receptor via an endorphin-like pathway. Acetyl tetrapeptide-15 is used in the cosmetics for sensitive skin.

Acetyl dipeptide-1 cetyl ester (Calmosensine) is a bioactive peptide with anti-aging effect and has been reported used as a cosmetic ingredient.
