What if I've already tried prescriptions?
Prescriptions target the breakout - not what keeps causing them. If acne comes back after every round of treatment, the internal driver was never found. This measures the hormone, blood sugar, and stress imbalances that creams and antibiotics can't see.
What if I've been tested before and everything came back normal?
Standard labs use generic reference ranges - 'normal' isn't the same as optimal for your skin. We interpret your levels specifically for acne, where being at the edge of a range can still drive breakouts. And if your panel comes back entirely clean, our 90-day guarantee means a full refund.
Can I use this with my dermatologist?
Yes - your report includes your actual lab values, so you can bring it straight to your derm. Most acne appointments never include this panel, so it makes that visit far more productive.
What if it doesn't work for me?
You're covered by our 90-day money-back guarantee. Fewer than 1% of customers ever use it.
Can I cancel the membership easily?
Yes - anytime, from your account, in about two clicks. No fees, no phone calls, no hoops.

“Turns out my acne wasn't hormonal at all - the test showed major gut inflammation and food sensitivities that were showing up on my face. I went from hiding behind makeup to posting makeup-free selfies for the first time IN MY LIFE!”

“I honestly cried when I read my report. For the first time, I knew WHY my skin was breaking out - high cortisol and low vitamin D. Having answers gave me so much peace of mind, and now my skin and confidence are both improving.”

Frequently asked questions

How does billing work?
$149 today for your first kit ($199 as a one-time test). Your membership renews at $49/month. That covers your Blueprint and updates, weekly specialist calls, unlimited Clara, and a free 12-marker retest every 90 days.
Can I cancel or pause?
Yes - anytime, from your account, in about two clicks. No cancellation fees, no phone calls.
Is this FDA approved?
Diagnostic test kits aren't FDA-approved products - that category applies to drugs. Every sample is analyzed in CLIA-certified laboratories, the same certification standard used for physician-ordered bloodwork.
Do I need a prescription?
No. You can measure the internal factors associated with your breakouts without a referral or an appointment.
Does the collection hurt? Are there needles?
Collection uses a painless arm device - not a syringe, not a vein draw. Most people finish in about 2 minutes.
Why not just get bloodwork at my doctor's?
A typical acne visit rarely includes a 12-marker panel, and standard lab reports use generic ranges with no skin-specific interpretation. We run the full panel from home, interpret it for acne, and retest every 90 days.
How fast do I get results?
Kits ship within 1–2 business days. Results and your Blueprint typically arrive within 7 days of the lab receiving your sample.
What if my panel comes back completely normal?
If your panel comes back entirely clean, our 90-day money-back guarantee applies - a full refund. Fewer than 1% of customers ever use it.
Can I use HSA/FSA funds?
Yes - testing and the plan are HSA/FSA eligible, so you can pay with pre-tax dollars.
What's in your kit?
A painless arm-collection device, prepaid return shipping, and step-by-step instructions. Collection takes about 2 minutes - no visits, no vein draws.
What do you test?
12 markers across four systems: hormones (Total T, Free T, SHBG, Albumin, DHEA-S), blood sugar (HbA1c), stress & inflammation (Cortisol, hsCRP), and nutrients (Vitamin D, B12, Ferritin, Creatinine).
