Frequently asked questions

Apply in this order, morning and night on cleansed skin: Step 1: Free Radical Neutralizing Oil to purify and prepare. Step 2: Reactivation Serum to drive deep renewal. Step 3: Barrier Shield Moisturizer to lock in actives and fortify the barrier.

Our products are designed to work synergistically for maximum results, and we do recommend using all three. That said, each product performs beautifully on its own and even better when combined as the full Sherak System.

Results build progressively with consistent use: • Immediately: skin feels softer and more nourished. • 2–4 weeks: improved smoothness and radiance. • 8+ weeks: visible firmness and wrinkle reduction.

Yes. Apply the serum on clean skin, allow it to absorb fully, then layer other treatments as tolerated. If using retinoids or retinols, they can be beautifully combined with the Barrier Shield Moisturizer in the evening.

Both, for optimal results. In the morning, complete your Sherak routine and then apply a broad-spectrum SPF. In the evening, the actives do their deepest renewal work while your skin is in recovery mode. Retinols or retinoids can be added to the Barrier Shield Moisturizer in the evening.

Our recommended starting amounts are: Oil: 3–4 pumps. Serum: 2 pumps. Moisturizer: 2 pumps. Adjust slightly by season and your skin’s needs.

Yes. We recommend shaking the Reactivation Serum before each use to fully disperse the peptides and active ingredients. This ensures you receive the complete concentration of the Pentapeptide Matrix™ with every application.

This occasionally happens due to air in the pump column during filling, and it is easily resolved. First, shake the bottle gently and depress the pump 10–15 times to work through any air. If the pump still does not prime, unscrew the pump from the bottle and depress it several times outside of the bottle to clear any remaining air bubbles, then reattach and try again. Your product is completely intact; this is simply an air-priming step.

Nothing is wrong, and your product is perfectly formulated. Some users notice an unexpected scent with highly concentrated active formulas. This is a natural characteristic of the amide compounds present in advanced peptide chemistry; the same concentration that makes these formulas so effective can release a faint, distinctive note. The scent dissipates within a few minutes of application and is in no way an indication that the product is off or compromised. It is, in fact, a subtle signature of highly effective agents.

The Pentapeptide Matrix™ is our proprietary blend of five biomimetic peptides, amplified by amino acids, flavonoids, ATP, and niacinamide. Together, they support pathways that increase collagen and elastin, smooth wrinkles, improve firmness, and accelerate visible skin renewal at the cellular level.

No parabens, microplastics, or artificial fragrances or colors. Our formulas are vegan, cruelty-free, and hormone-free.

Yes. Our formulas are designed to be highly effective yet gentle on skin. As with any active skincare, we recommend a patch test first and a gradual introduction to your routine.

No. Sherak is completely hormone-free.

Because skin’s natural renewal process slows significantly after 40. Higher-performance actives, especially peptides and antioxidants, help reinforce firmness, hydration, and resilience where skin needs it most. Generic formulas built for younger skin simply do not address the biology of midlife skin.

Peptides support pathways that signal renewal and firmness at the cellular level. Antioxidants neutralize free radicals that accelerate visible skin aging. Together, they protect and rebuild, addressing two distinct and complementary mechanisms for healthier, more resilient skin.

The Pentapeptide Matrix™ targets wrinkle depth and volume through multiple peptide pathways, while antioxidants defend against the oxidative stress that accelerates visible aging. Clinical observations of our peptides show a 31% reduction in wrinkle volume with consistent use.

Yes. Biomimetic peptides in the Pentapeptide Matrix™ support pathways that increase collagen and elastin, improving firmness, lift, and facial contour definition over time. Clinical data of the individual ingredients show a 28% increase in forehead lifting with consistent use of the Sherak System.

Yes. Actives in our Reactivation Serum reinforce the dermal matrix help refine the appearance of age-related enlarged pores and smooth visible skin texture with consistent use.

Absolutely. The Sherak System layers nourishing oils, humectants, and barrier-strengthening actives to restore bounce, deep hydration, and lasting comfort. The Barrier Shield Moisturizer is specifically formulated to reinforce the skin’s natural moisture barrier.

Yes. Calming antioxidants and barrier-supportive ingredients help reduce the appearance of redness and improve skin resilience over time.

Yes. Stabilized vitamin C and renewing peptides work together to brighten and even the appearance of skin tone, including dark spots and discoloration, with consistent use.

We formulate to dermatological standards and partner with an expert laboratory. We are committed to safety, transparency, and measurable, visible performance.

Our ingredient selection is guided by clinical literature, and we conduct performance evaluations to validate visible results. Clinical observations of our individual ingredients include a 28% increase in forehead lifting and a 31% reduction in wrinkle volume with consistent system use.

Absolutely. Sherak was created for the evolving biology of midlife skin.

Our formulas are hormone-free and formulated with safety as a foundation. Every pregnancy and breastfeeding journey is unique, so we encourage you to consult your healthcare provider for personal guidance.

We share meaningful details about key actives and their functions. What matters most is proven ingredients in concentrations designed for real results and skin tolerance, not numbers that look impressive on a label but lack clinical context.

Absolutely. Sherak was created for the evolving biology of midlife skin and is designed to support skin through every stage of that journey.

Sherak was founded and formulated by Jennifer Sherak, a female chemist and former pharmaceutical executive with over 30 years in pharmaceutical drug development and commercialization. Jennifer spent her career creating biotech-driven therapies for complex biological challenges before founding Sherak to bring that same level of scientific rigor and precision to skincare for women over 40.

Sherak shares SkinCeuticals’ commitment to evidence-backed formulation, but was built specifically for the biology of women over 40, a distinct skin profile that most clinical brands do not address as a primary focus. Our proprietary Pentapeptide Matrix™ delivers 5x the peptide concentration of leading luxury brands, in a streamlined three-step system that eliminates the complexity of a multi-product clinical regimen.

Skin Renewal Chemistry is the Sherak philosophy: the belief that precision-formulated, biotechnology-driven ingredients can meaningfully support how skin functions and renews at the cellular level. It is the alternative to temporary optical fixes (think primers) or single-ingredient formulas, a complete, synergistic chemistry system designed to work with the skin’s own biology.

Empowered aging is the belief that midlife is not a decline to manage but an evolution to embrace with confidence, clarity, and science-backed support. At Sherak, we do not formulate against aging; we formulate for the woman who is becoming more fully herself, and we believe her skin should reflect that.
