AccessPEP AH8

Advanced Anti-Wrinkle Peptide for Expression Lines and Deep Wrinkles

INCI Name: Aqua, Acetyl Hexapeptide-8, Caprylyl Glycol, Ethylhexylglycerin

AccessPEP AH8 is a clinically-proven anti-wrinkle peptide for cosmetic formulation, featuring acetyl hexapeptide-8 in an easy-to-use solution. As a biomimetic peptide, it effectively targets expression lines and deep wrinkles by inhibiting the SNARE complex, which reduces the intensity of muscle contractions. This mechanism visibly smooths forehead lines, crow’s feet, and frown lines, making it an ideal active for advanced anti-aging serums, eye creams, and targeted treatment products.

    Specifically targets crow's feet and fine lines in delicate eye area formulations, with proven safety for sensitive skin zones.
  • Anti-Wrinkle Night Creams
    Works overnight in rich, nourishing bases to smooth deep-set expression lines while the skin is in its natural regenerative state.
  • Forehead & Frown Line Treatments
    Provides targeted, potent treatment for dynamic wrinkles caused by repeated facial movements in spot-treatment and roll-on formats.
  • Professional Treatment Masks
    Delivers an intensive peptide concentration in sheet masks or wash-off treatments for an immediate, visible smoothing effect.
  • Multi-Active Anti-Aging Complexes
    Combines synergistically with other peptides, antioxidants, and hydrators in comprehensive age-defense formulations.

Performance & Formulation Insights for AccessPEP AH8

How Acetyl Hexapeptide-8 Reduces Expression Lines

AccessPEP AH8 works through a unique mechanism that mimics the N-terminal end of SNAP-25, a protein essential for neurotransmitter release at the neuromuscular junction. When applied topically, the acetyl hexapeptide-8 peptide competes with SNAP-25 for a position in the SNARE complex, which is responsible for triggering muscle contraction. By disrupting the formation of this complex, the peptide reduces the intensity of the muscle contractions that cause expression lines. This provides a topical, non-invasive alternative to injectable treatments by specifically targeting dynamic wrinkles—those caused by facial movements—rather than static wrinkles from sun damage or aging.

Formulation Guidelines for Optimal Performance

AccessPEP AH8 is supplied as a clear, ready-to-use aqueous solution, simplifying incorporation into water-based systems and emulsions. For best results, add it to the water phase of your formulation during the cool-down phase (below 40°C) after primary emulsification. The peptide remains stable and effective across a pH range of 4.0–7.0, with optimal performance typically seen between pH 5.0–6.0. It demonstrates excellent compatibility with other anti-aging actives, including hyaluronic acid, vitamin C derivatives, and other peptides, making it a versatile choice for multi-functional products.

Key Formulation Benefits

  • Visible Wrinkle Reduction: Clinical studies on acetyl hexapeptide-8 demonstrate a measurable reduction in wrinkle depth and length with consistent use, proving particularly effective on forehead lines and crow’s feet.
  • Topical ‘Botox Alternative’: Offers a compelling needle-free marketing story for consumers seeking to reduce expression lines without invasive procedures.
  • Fast-Acting Results: Formulations with effective concentrations can show initial smoothing effects within 2–4 weeks, with optimal results appearing after 8–12 weeks of consistent twice-daily application.
  • Excellent Stability: The pre-dissolved liquid format ensures consistent concentration and eliminates the solubility challenges associated with handling peptide powders.
  • Synergistic Potential: Combines effectively with collagen-boosting peptides, antioxidants, and hydrating actives to create comprehensive, multi-pathway anti-aging systems.
  • Eye Area Safe: Extensively tested for use in delicate eye area formulations, where expression lines are most prominent and visible.

Frequently Asked Questions About AccessPEP AH8

We recommend using AccessPEP AH8 at 2–5% for daily maintenance and preventative anti-aging products. For intensive treatment serums and targeted wrinkle-reducing formulations, a concentration of 5–10% is recommended for faster, more pronounced results.
Acetyl hexapeptide-8 is a neurotransmitter-inhibiting peptide that specifically targets the mechanism of muscle contraction to reduce expression lines. This is different from signal peptides (like Matrixyl) which work by stimulating collagen production in the dermis.
Yes, it is compatible with most vitamin C derivatives and can be used in routines that include retinol. For maximum stability and efficacy, it is often best to formulate them carefully regarding pH or recommend application at different times of day (e.g., peptide in the morning, retinol at night).
AccessPEP AH8 remains stable within a pH range of 4.0 to 7.0. The optimal pH for both stability and skin compatibility is between 5.0 and 6.0.
Yes, acetyl hexapeptide-8 is a well-studied peptide with multiple clinical trials demonstrating its efficacy in reducing the depth and appearance of wrinkles. For detailed clinical study summaries, please contact our technical team.
Absolutely. AccessPEP AH8 is extensively tested and proven safe for use in eye area formulations. It is highly effective at targeting crow’s feet and other expression lines around the eyes.
