Inner CircleUndertone Tuner Customer Service
Undertone is a precision tool for tattoo artists and clients. Fresh tattoos often come with redness and inflammation that can distract from the actual work. Undertone removes that redness while keeping the skin tone and tattoo detail intact.
How it works:
Select or take a photo of a fresh tattoo.
Paint over healthy skin near the tattoo to set a reference tone.
Tap Apply. Undertone uses Lab color space analysis to neutralize redness across the image.
Fine-tune with Strength, Threshold, and Brightness sliders.
Use the Exclude brush to protect specific areas from correction.
Save the final image at full camera resolution.
