What it is

What Radiant does

Measures skin appearance from a guided photo or video scan, builds a routine with each recommendation linked to its source, and re-measures over twelve weeks so you can see whether the routine changed anything. All on-device.

Skincare advice is mostly assertion. Radiant does three things instead: it measures the appearance of skin from a guided scan, it builds a routine where each recommendation carries its citation, and it re-measures over twelve weeks so the question 'did this do anything' has an answer.

Everything runs on-device — no account, no upload, no server — which matters more here than in most categories, because the input is photographs of your face.

How it does its job

Guided capture

Consistent conditions, because comparing photos taken under different light measures the light.

Cited recommendations

Each suggestion links to the evidence behind it rather than asserting authority.

Twelve-week tracking

Change measured over a period long enough to be real.

What it doesn't do

It measures appearance, not skin health, and it is not a medical device. Anything clinical belongs with a dermatologist.

Native, local-first, and yours

Radiant is a native Mac app distributed as a complete, fully activated download. No subscription, no account, no locked features, no tracking.
