The Science

The science your mirror can't see.

Every biomarker in your panel is connected to a specific mechanism of skin aging published in peer-reviewed journals and cited by researchers at Harvard, Mayo Clinic, and NIH.

Skin close-up
Glycation
HbA1c

Crosslinks collagen and accelerates skin stiffening.

Inflammaging
hsCRP

Chronic low-grade inflammation activates enzymes that break down collagen and elastin the structural proteins that keep skin firm.

Hormonal Aging
Estradiol

Regulates collagen production and skin thickness.

Aesthetic Response
Zinc

A 2012 RCT (Koshy et al., JDD) reported zinc + phytase extended Botox duration by ~30%. Critics noted no baseline zinc was measured — JenSkin measures yours first. Inflammation markers like hsCRP can also affect how skin responds to procedures, and elevated HbA1c can impact healing.

· · ·
9 biomarkers in total

Each one mapped to a specific mechanism of skin aging peer-reviewed and cited by researchers at Harvard, Mayo Clinic, and NIH.

Skin Longevity Report
Sarah M., 42
Panel Date: April 2026 · Panel 1 of 1
HbA1c (Glycation) 5.8% · Elevated
hsCRP (Inflammation) 2.1 mg/L · High
Vitamin D 38 ng/mL · Low
Omega-3 Index 4.2% · Below optimal
Treatment Sequencing Recommendation
Address glycation and inflammation first before investing in microneedling or laser. Reducing hsCRP below 1.0 mg/L will significantly improve treatment response.

Use cases

Three women. Three very different reports.

The same panel. Personalized to what each one actually needs to address before spending another dollar on her face.

Concern · Botox
Sarah, 42
"My Botox stopped lasting as long. I assumed I was just metabolizing it faster."
Concern · Collagen loss
Cheryl, 54
"My skin changed dramatically after menopause. Nothing I tried seemed to help."
Concern · Adult acne
Maya, 31
"I'd tried every prescription. My derm wanted to put me on Accutane again."
Composite cases based on the JenSkin panel. Sarah, Cheryl, and Maya are illustrative.

Yes. Your data is encrypted in transit and at rest. We never sell or share your health information. Ever.
Your report will flag any markers that need urgent attention and direct you to speak with a physician before making any changes. JenSkin is informational — your doctor makes clinical decisions.
Yes. We recommend retesting every 6 months to see how your interventions are moving your markers. Your second panel will be at member pricing.
No. Standard blood panels are designed to detect disease. JenSkin uses longevity-optimized reference ranges specifically mapped to skin aging mechanisms — a fundamentally different lens on the same biology.
No, JenSkin does one step better. We measure the upstream drivers that destroy or preserve your collagen with our proprietary blood panel. By the time collagen loss is visible, the damage is done. We measure what's causing it so you can intervene before it happens.
No. JenSkin is a wellness panel, not a diagnostic test. Your report is for informational and educational purposes only and does not constitute medical advice, diagnosis, or treatment. If your results raise clinical concerns, we flag them and recommend you consult a licensed physician.
Our Story

I was tired of being told what to put on my skin. I wanted to know what was happening inside it.

I'm Jennifer. I'm a working mom of two — a four year old and a one year old. Between school runs and midnight wake-ups, I was drowning in skincare products, each one promising to fix something different. Serums, retinols, acids, moisturizers. Every brand had an answer. None of them could tell me why my skin was the way it was.

I kept thinking — true beauty isn't a product. It comes from the inside. And if blood can tell a doctor what's wrong with your health, why can't it tell us what's driving how our skin ages?

So I started researching. The science was already there — glycation destroying collagen, inflammation breaking down elastin, hormones regulating everything. It just wasn't connected to skincare in a way that was simple or accessible.

JenSkin started as a side project — a way to finally get a clear answer tailored to my skin, not a generic recommendation. One panel. Nine biomarkers. A report that tells you exactly what to address first, so you stop guessing and start knowing.
