About The Founder

Meet Jennifer Sherak
Founder & Chief Formulator

Jennifer Sherak is a chemist and pharmaceutical executive with expertise in advanced peptide and biotechnology-driven therapies, bringing more than 30 years of experience from the global healthcare industry. Throughout her career, she developed and commercialized innovative treatments that addressed critical, unmet medical needs worldwide. With this foundation in molecular science and a relentless focus on efficacy, she founded Sherak to apply the same level of scientific rigor and innovation to skincare for women over 40.

Recognizing that traditional products often stop working as skin evolves in midlife, Jennifer created Sherak as a biotechnology-powered solution tailored to the biology of maturing skin. At the core of every formula is her proprietary Pentapeptide Matrix™—a clinically advanced blend of bioengineered peptides that restore firmness, stimulate cellular renewal, and strengthen the skin barrier.

Sherak is a reflection of Jennifer’s lifelong commitment to science and her belief that women deserve more—more efficacy, more innovation, and more confidence. Each formula combines scientific precision with luxurious simplicity, empowering women to embrace midlife with visible results, delivered through elegance, intelligence, and integrity.

Formulated for This Chapter

Sherak was created for women who want real results with real transparancy. As a chemist, I believe in evidence, precision and formulations that work deeper in your skin. As a woman, I believe aging isn't something to correct or change, it's something to own.

Every Sherak formula is desinged to support skin through midlife with intention and intelligence. No gimmicks. No empty promises. Just powerful chemistry, intentional design, and skincare created with you at the center.

This is your time to shine.

With science and grace,

Science at the core

The Pentapeptide Matrix™

At the heart of every Sherak formula is our proprietary Pentapeptide Matrix™—a biotechnology-powered blend of five advanced peptides and peptide boosters.

This clinically supported complex is designed to:

  • Support collagen and elastin production
  • Improve firmness and elasticity
  • Smooth the appearance of fine lines and wrinkles
  • Strengthen the skin barrier
  • Accelerate visible skin renewal

Rather than isolating peptides in a single product, the Pentapeptide Matrix™ is woven throughout the Sherak System—because peptides perform best when skin is prepared, supported, and protected at every step.
