AccessPEP APT-1 PWD

High-Performance Firming Peptide for Collagen & Elastin Synthesis

INCI Name: Acetyl Pentapeptide-1

AccessPEP APT-1 PWD is a high-purity, powder form of Acetyl Pentapeptide-1, a biomimetic signal peptide designed to restore skin’s youthful structure. It works by stimulating fibroblast activity, boosting the synthesis of essential dermal proteins like collagen and elastin. This targeted action helps improve skin density, increase firmness, and reduce the appearance of sagging and fine lines, making it a cornerstone active for advanced anti-aging and skin-firming formulations.

Solubility Notes:

Water-soluble powder. Pre-dissolve in the water phase at room temperature. Add during the cool-down phase and avoid temperatures above 40°C (104°F) to protect peptide integrity.

Performance & Formulation Insights for AccessPEP APT-1 PWD

How Acetyl Pentapeptide-1 Rebuilds Skin Structure

AccessPEP APT-1 PWD features Acetyl Pentapeptide-1, a signal peptide that plays a crucial role in dermal repair and regeneration. As skin ages, the production of collagen and elastin—the proteins responsible for its firmness and elasticity—declines. Acetyl Pentapeptide-1 works by signaling fibroblasts, the skin cells that produce these proteins, to increase their synthesis. By stimulating the production of Type I collagen and elastin, this peptide helps to rebuild and reorganize the extracellular matrix. The result is a denser, stronger dermal structure that translates to visibly firmer, smoother, and more resilient skin with a reduction in wrinkles and sagging.

Formulation Guidelines for Optimal Performance

As a high-purity powder, AccessPEP APT-1 PWD offers formulation flexibility and high potency. It is readily soluble in water. For best results, pre-dissolve the powder in a portion of the water phase at room temperature before adding it to the main batch. Avoid prolonged exposure to high heat (above 40°C / 104°F) to maintain peptide integrity. The optimal pH for formulations containing Acetyl Pentapeptide-1 is between 5.0 and 7.0. This peptide is highly compatible with other anti-aging actives, including hyaluronic acid, antioxidants, and other peptides, allowing for the creation of powerful, multi-functional products.

Key Formulation Benefits

Boosts Collagen & Elastin: Directly stimulates the synthesis of key structural proteins for measurable improvements in skin firmness and elasticity.
Reduces Wrinkles & Sagging: By reinforcing the skin’s dermal structure, it helps diminish the appearance of fine lines, wrinkles, and skin laxity.
High-Purity Powder: Offers maximum formulation flexibility and potency compared to pre-diluted solutions, allowing for precise control over concentration.
Excellent Stability: Stable in a typical cosmetic pH range (5.0–7.0), ensuring reliable performance in a variety of bases.
Synergistic Effects: Combines effectively with other anti-aging ingredients like retinoids, vitamin C, and hydrating actives to create comprehensive age-defying formulas.
Targeted Action: As a signal peptide, it provides a specific, targeted mechanism for improving the skin’s foundational support system.

Frequently Asked Questions About AccessPEP APT-1 PWD

The recommended concentration is between 0.5% and 3% in the final formulation, depending on the desired intensity of the product.

It acts as a signal peptide, stimulating fibroblasts in the skin to produce more collagen and elastin. This helps to rebuild the skin’s supportive matrix, leading to increased firmness and fewer wrinkles.

Pre-dissolve the powder in a small amount of distilled water from your water phase, then add it to the batch during the cool-down phase (below 40°C) to protect the peptide’s structure.

Yes, it can be formulated with AHAs. Ensure the final pH is within 5.0–7.0 for peptide stability. Many formulators prefer using peptide products separately from low-pH acid treatments to optimize efficacy.

Acetyl Pentapeptide-1 is a signal peptide that builds and repairs skin structure by boosting collagen and elastin synthesis. In contrast, peptides like Acetyl Hexapeptide-8 target expression lines by moderating muscle contractions—different yet complementary mechanisms.

Yes. Acetyl Pentapeptide-1 is a synthetic peptide produced without animal-derived components and is suitable for vegan and cruelty-free formulations.
