Your skin, decoded

Meet Juni One

Precision sensors measure key signals from your skin, delivering personalized insights to your skincare routine.

Moisture sensors measure transepidermal water loss to evaluate the hydration and strength of your skin’s barrier.

Integrated contact electrodes non-invasively measure skin impedance, adding depth to your skin profile.

Sensor fusion brings this data together over time, giving you immediate, personalized feedback on your skin.

Made for your skin. Not everyone’s.

Your analysis pick the products for you

Most skincare camera apps recommend products based on what you tell them. We recommend based on what your skin actually shows us.

"Switch to a ceramide rich moisturizer"

Your pH shifted after cleansing
"Try a low-pH cleanser instead"

Deep hydration is low
"Add a hyaluronic acid serum"

Every recommendation is tied to a real reading, not a brand deal. We only suggest products that move your scores in the right direction.

The skincare device people wish they’d bought sooner.

★★★★★

"I found out my $80 cleanser was destroying my barrier."

Switched to a low-pH cleanser after my Structure score dropped. Two weeks later, it was back up to 12%.

★★★★★

"The most important part of my routine."

I’ve spent years cycling through products. This is the first time I’ve had proof something is working.

★★★★★

"I caught a breakout three days before it happened."

My pH shifted and the app flagged it. Changed my routine and it never surfaced. That alone paid for the device.

★★★★★

"Finally realized that my phone camera cannot fix my acne."

I have wasted hundreds on flimsy phone apps and camera clip ons that detect nothing, Juni has helped reduce my breakouts almost instantly.
