About the Founder

Meet Jennifer Sherak

Founder & Chief Formulator

For more than thirty years, Jennifer Sherak helped develop therapies in the pharmaceutical industry. Then her skin began to change, and she realized the products she was using had never been designed for women like her. So, at 54, she set out to build Sherak.

Formulated and founded by a midlife chemist, made for every woman who refuses to believe her best years are behind her.

In her words

I fell in love with the beauty business at seven, sorting lipsticks and body care on my grandmother’s kitchen table. She was an Avon lady, and to me she was something close to magic: a woman who made other women feel beautiful and paid me in lip balm and bubble bath. By nine, I had my own chemistry set and a question I asked again and again: “How do I make this better?”

That question became a 30 year career. I trained as a chemist and spent decades in the pharmaceutical industry, developing therapies for some of the most complex, unmet medical needs. My last position was an executive role at a Fortune 10 healthcare company. I learned to respect evidence, insist on precision, and never make a promise the science could not keep. Those are not marketing words to me. They are simply how I was taught to work.

Then midlife arrived, and my skin began to change. Like so many women I know, I reached for the products I had trusted for years, only to find they no longer had much effect on my skin. So I did what any scientist does. I started researching existing brands, looking for skincare based on biotechnology for mature skin. I couldn't find it. The beauty industry prefers to focus on youth rather than on women over 40. That is when I knew I needed to do something about this.

Women over 40 are not finished. We are finally in our prime.

So, I built what I could not find. Sherak is the result, and at the heart of every formula is my proprietary Pentapeptide Matrix™, a biotechnology-powered blend of five advanced peptides, each with a precise, targeted role. Together, they support the pathways that increase collagen and elastin, strengthen the skin barrier, accelerate visible renewal, and target skin longevity. Sherak delivers 5 times as many peptides as leading luxury brands. Our ingredients are primarily actives, with no gimmicky ingredients. Because let’s face it: at our age, we don’t follow trends. We want results.

I built Sherak for every woman who has spent decades building a career, a family, and a life of her own design, and who deserves skincare as intelligent and intentional as she is.

My mission is simple: to empower women over 40 with biotechnology powerful enough to match their needs, and formulas that restore firmness, vitality, and radiance with the precision midlife skin deserves. But my vision extends beyond any single bottle. I want to change the way the world sees women in this chapter and the way we see ourselves.

Sherak is more than a system. It is a movement and a growing community of women who believe in real science, real results, and each other. When you choose Sherak, you are not buying a product. You are joining a circle of women who are just getting started.

You are not slowing down. Neither should your skincare.

With grace & gratitude,

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.
