Description
What is Palmitoyl Tetrapeptide-7 Bulk?
Palmitoyl Tetrapeptide-7 is a synthetic biomimetic peptide widely used in anti-aging and skin care formulations. It is made by linking a fatty acid (palmitic acid) with a short chain of four amino acids (Gly-Gln-Pro-Arg, GQPR). The palmitoyl group improves the peptide’s oil solubility and skin penetration.
Palmitoyl tetrapeptide-7 is often added to anti-wrinkle creams, serums, eye care products, and firming formulas. It can also help regulate skin inflammation pathways and support a healthier extracellular matrix environment.
Maxmedchem supplies palmitoyl tetrapeptide-7 bulk powder with a purity of ≥99%, good water solubility, and stock in our US warehouse. We provide complete technical documentation including COA, TDS, and production flow charts.

Palmitoyl Tetrapeptide 7 in Skin Care
1. Anti-Aging Serums
Palmitoyl Tetrapeptide-7 is a key active ingredient in facial serums targeting fine lines and wrinkles. It is often combined with other peptides, hyaluronic acid, niacinamide, or antioxidants to provide comprehensive anti-aging benefits.
2. Anti-Wrinkle Face Creams
Many day and night creams incorporate Palmitoyl Tetrapeptide-7 to help maintain skin firmness and elasticity while protecting the skin from environmental stress.
3. Eye Care Products
The delicate eye area is particularly susceptible to signs of aging. Palmitoyl Tetrapeptide-7 is commonly used in eye creams and eye serums to improve the appearance of crow’s feet and under-eye wrinkles.
4. Firming and Lifting Products
Firming creams, neck creams, and lifting serums frequently include Palmitoyl Tetrapeptide-7 as part of peptide complexes designed to improve skin resilience.
5. Sensitive Skin Care
Because it helps regulate inflammatory responses, Palmitoyl Tetrapeptide-7 is also used in formulations designed for stressed or sensitive skin, including products intended to support the skin barrier after cosmetic treatments.
