AccessPEP APT-1 sol.

Q: What is the primary function of AccessPEP APT-1 sol.?

Its primary function is to firm the skin and improve elasticity. It works by signaling skin cells to produce more collagen, elastin, and other structural proteins, thereby strengthening the skin’s support matrix.

Q: What is the recommended usage rate?

For daily use and maintenance, a concentration of 2-5% is recommended. For more intensive firming treatments or targeted products, the usage rate can be increased up to 10%.

Q: Can this peptide be combined with other actives like retinol or AHAs?

Yes. It can be formulated with other actives. When combining with potent exfoliants like AHAs or retinoids, ensure the final formulation pH is within the peptide’s stability range (5.0-7.0) or suggest alternating usage to maximize the efficacy of each active.

Q: How does Acetyl Pentapeptide-1 differ from a neuropeptide like Acetyl Hexapeptide-8?

Acetyl Pentapeptide-1 is a signaling peptide that rebuilds the skin’s structure by boosting collagen and elastin. In contrast, neuropeptides like Acetyl Hexapeptide-8 work by relaxing facial muscles to reduce expression wrinkles—different, but complementary, mechanisms of action.

Q: Is this ingredient suitable for eye creams?

Yes, Acetyl Pentapeptide-1 is well-suited for use in eye contour products to help firm the delicate skin and reduce sagging around the eye area.

Q: What is the optimal pH range for formulations containing AccessPEP APT-1 sol.?

This peptide performs best in formulations with a pH between 5.0 and 7.0.

Advanced Firming Peptide for Dermal Repair and Elasticity

INCI Name: Aqua, Acetyl Pentapeptide-1, Phenoxyethanol, Ethylhexylglycerin

AccessPEP APT-1 sol. is a high-performance firming peptide featuring Acetyl Pentapeptide-1 in a ready-to-use solution. This biomimetic peptide acts as a powerful signaling agent, stimulating fibroblasts to rebuild the dermal matrix by boosting the synthesis of collagen, elastin, and fibronectin. It effectively improves skin firmness, enhances elasticity, and reduces the appearance of sagging for a more lifted and youthful contour. Ideal for advanced anti-aging and skin-firming cosmetic lines.

Solubility Notes:

Water-soluble, add to the water phase or during the cool-down phase of formulation (<40 °C).

Performance & Formulation Insights for AccessPEP APT-1 sol.

How Acetyl Pentapeptide-1 Works

Acetyl Pentapeptide-1 is a signaling peptide that mimics a fragment of elastin, a key protein responsible for skin’s flexibility and resilience. When applied to the skin, it binds to specific receptors on fibroblasts—the cells responsible for producing structural proteins. This interaction signals the fibroblasts to ramp up production of essential components of the extracellular matrix, including collagen I and III, elastin, and fibronectin. By stimulating this regenerative process, Acetyl Pentapeptide-1 helps to reorganize and strengthen the skin’s underlying support structure, leading to measurable improvements in firmness, elasticity, and a reduction in skin sagging.

Formulation Guidelines

AccessPEP APT-1 sol. is an easy-to-use aqueous solution that can be seamlessly incorporated into various cosmetic formulas. For optimal results, add it to the water phase of your formulation or during the cool-down phase at temperatures below 40 °C (104 °F) to protect the peptide’s integrity. This active is stable within a typical cosmetic pH range of 5.0 to 7.0. It is highly compatible with other anti-aging ingredients like hyaluronic acid, vitamin C derivatives, and other peptides, allowing for the creation of powerful, multi-functional products. Recommended usage rates are between 2% for maintenance and 10% for high-performance firming treatments.

Key Formulation Benefits
