Myristoyl Pentapeptide-4 Related Research

1.Core Mechanism and Primary Effects

N-terminal myristoylation significantly improved its lipophilicity and skin permeation, enabling the peptide to bind directly to IGF-1 receptors and activate downstream signaling.

This, in turn, reawakens age-related deceleration of anabolic cutaneous processes; it upregulates the synthesis rate of a variety of key extracellular matrix proteins such as Type I collagen, Type III collagen and elastin – actively reversing dermal cell degradation caused by ageing.

This greatly increases the density and thickness of dermal tissue, demonstrating a potent ability to reduce or erase static wrinkles.

2.Facilitates Synthesis of Type I and III Collagen

Collagen type I and III are the key determinant proteins for skin elasticity and firmness.

Their natural synthesis capacity declines sharply with age.

Myristoyl Pentapeptide-4 functions by mimicking IGF-1 signaling, binding to the insulin-like growth factor-1 receptor and activating anabolic responses in fibroblasts.

This increases the production of Type I and III collagen, which thickens the dermis while reducing fine lines and wrinkles associated with ageing. 1

3.Boosts Elastin Synthesis and Organization

Myristoyl Pentapeptide-4 upregulates elastin gene expression and protein production during fibroblast activation.

It stimulates newly produced proteins to organize into an ordered elastic fiber network, which reinforces the skin’s supporting layer.

This increases the elasticity of skin, quickly smoothing wrinkles resulting from loss of inner support, while also counteracting sagging.

Skin texture instantly becomes smoother, improving overall skin condition.
