Clinical-grade insights, in your bathroom

Four novel sensors capture what no mirror or camera can show. 90 seconds, morning and evening, builds a personal skin model that connects your habits to your biology.

  • HydrationKnow what’s happening beneath the surface
    82Score
    Well Hydrated

    Surface loss rate, deep cellular fluid levels, and recovery speed after washing reveal whether your skin is truly hydrated or just feels like it.

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.

From our community

The skincare device people wish they’d bought sooner.

4.8 out of 5 stars from 200+ reviews. Rated the #1 skin health device by real users tracking real results.

  • ★★★★★

    "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.
