Peptides are short chains of amino acids that act as biological messengers by communicating with skin cells to support collagen pathways, elastin synthesis, and skin barrier integrity.
As skin matures, these cellular signals naturally decline. Peptide-based skincare works with the skin’s own biology to help re-engage these pathways—supporting visible renewal rather than relying on temporary optical effects.
At the core of every Sherak formula is our proprietary Pentapeptide Matrix™, a biotechnology-powered complex of five advanced peptides, each with a distinct, targeted function. Intentionally formulated by a midlife chemist for midlife skin, this multi-pathway approach is designed to improve firmness, refine texture, and support long-term skin vitality.
When used consistently as a complete system, our peptide-based actives have been shown to deliver measurable improvements in skin appearance and structure:
28% increase in forehead lifting
31% reduction in wrinkle volume
Improved firmness, elasticity, and facial contour definition
Noticeably smoother skin texture and reduced roughness
Decreased jowl surface area and improved jawline curvature
