At-Home LED Masks
- The claim
- Clinic-grade light therapy at home, for collagen, acne and redness.
- The verdict
- The same mechanism as clinic red light, usually at a dose nobody will tell you.
- Worth it?
- Only if you already own one. Buying one instead of a retinoid is a poor trade.
What the evidence supports
The underlying question is the same as for red light therapy generally, and the answer sits one grade lower because of dose. Clinical response to photobiomodulation is biphasic, so the delivered irradiance and the treatment time together decide whether anything happens. Very few consumer masks publish irradiance at the distance the mask actually sits from the face, and the ones that do are often an order of magnitude below the devices used in the trials being cited on the box.
Why this entry is short
This is a graded stub. The verdict, the grade and the citations are settled and reviewed; the long-form write-up is queued behind a recorded consult-room explanation, in the order these questions actually come up in the office. The row is here now because an evidence index with twenty honest lines is more use than one with four essays and nothing else.

Grades describe the quality of the human evidence, not my opinion of the treatment. Where the literature changes, the grade changes and the review date moves with it.

When to start, how often to repeat, and what the word preventative is actually describing. The mechanism is well understood; most of the confusion is about scheduling, and most of the marketing is about starting earlier.
