Copper-binding tripeptide, synthetic, aimed at dermal papilla cells and hair follicles. Hair follicles elongate, cells proliferate, VEGF production rises, and TGF-β1 is inhibited. Skin regeneration is supported by way of fibroblast activation and collagen synthesis.

Copper tripeptide, naturally occurring, present in human plasma, saliva, and urine. It affects 31.2% of human genes, and its level drops significantly with age: roughly 200 ng/ml at age 20 against roughly 80 ng/ml at age 60. Skin regeneration, wound healing, and anti-aging properties are what it is known for.

Synthetic α-MSH analog with selective action at MC1 receptors, stimulating melanin. As the SCENESSE implant it holds FDA approval for erythropoietic protoporphyria (EPP). The research-grade injectable allows dosing flexibility the implant version does not.

Synthetic octapeptide serving as a topical alternative to Botox, aimed at dynamic facial wrinkles by way of SNARE complex modulation. Clinical work demonstrates wrinkle depth reduced by up to 63%.

Synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) whose activity spans melanocortin receptors throughout the body. Melanin production for tanning follows MC1R activation, while the MC4R effect falls on sexual arousal and appetite control.
