Most people buying an LED face mask pick a mode the same way they pick a phone wallpaper: whichever looks nicest. That is a problem, because red, blue and near-infrared light are not interchangeable. Each wavelength is used for a different skin concern, and running the wrong one means weeks of consistent use with nothing to show for it.
In September 2026, Dr. Thais Prota Hussein Pincelli, a US board-certified dermatologist, published a carousel on Instagram breaking down exactly this question. Below is her post, followed by our plain-English summary of what each mode does and how to choose.
The three modes, in one table
| Mode | Wavelength | What it is used for |
|---|---|---|
| Red | 630 ± 5 nm | Fine lines and wrinkles |
| Blue | 465 ± 5 nm | Mild-to-moderate acne |
| Red + Near-Infrared | 630 ± 5 nm + 850 ± 5 nm | Red light with an added near-infrared wavelength, as an additional option in your routine |
Red light: the wrinkle mode
Red light in the 630 ± 5 nm range is the wavelength most LED masks are known for. It is the mode you choose when your main concern is fine lines and wrinkles. On Photira, red light is one of the two indications covered by our FDA 510(k) clearance (K254007): the device is cleared for use on wrinkles.
Blue light: the acne mode
Blue light at 465 ± 5 nm is a different tool for a different job. It is used for mild-to-moderate acne, and it is the second indication covered by Photira's clearance. As Dr. Pincelli notes in her post, it is for mild-to-moderate acne. If you have severe or cystic acne, an LED mask is not a substitute for seeing a dermatologist.
Red + near-infrared: the combined mode
Near-infrared (850 ± 5 nm) is invisible to the eye. On Photira it does not run alone; it is layered on top of red light in the combined mode. Dr. Pincelli describes it as "an additional option" in a routine. We describe it the same way. It is not a separate FDA indication, and we do not make claims for it beyond what the red light mode is cleared for.
How to choose, in one sentence each
- Fine lines and wrinkles are your main concern: Red.
- Breakouts are your main concern: Blue.
- You want red light and are curious about near-infrared: Red + NIR.
- You have both concerns: alternate sessions rather than trying to do everything at once. On Photira, blue runs on its own and cannot be combined with near-infrared.
The part most brands leave out
The line from Dr. Pincelli's post that we think matters most is not about wavelengths at all. She frames LED therapy as an addition to your skincare routine, not a replacement for the basics, with sunscreen still coming first. We agree. An LED mask is a 10-minute step you add to cleansing, moisturizing and daily SPF. It does not replace any of them.
Her suggested order of operations, which matches the manufacturer guidance for Photira: cleanse, use the LED mask on clean dry skin, then apply your skincare. In the morning, sunscreen.

Frequently asked questions
Can I use red and blue light at the same time?
Not on Photira. Red (alone or with near-infrared) and blue run as separate modes. If you have both wrinkles and acne concerns, alternate sessions.
Is near-infrared FDA-cleared on Photira?
Photira's 510(k) clearance covers wrinkles and mild-to-moderate acne. Near-infrared is offered as part of the combined red mode; we do not make separate claims for it.
How long is a session?
10 minutes per session, 3 times per week, following the included instructions.
Does Dr. Pincelli endorse Photira?
Dr. Pincelli is a paid partner and shared her own experience using Photira in her routine. Her post is disclosed as a paid partnership on Instagram, and this article is disclosed the same way at the top.
