Key facts
✓The Solara has 660nm red and 850nm near-infrared light built in, with full-spectrum infrared heat up to 158°F.
✓In a 2025 trial, 95 women aged 45 to 60 used a real or a fake 660nm red light mask for four weeks.
✓79.6% of the women using it three times a week were satisfied with their skin. Twice a week did as well as three.
✓No study has tested red light inside a sauna. The studies used masks, panels and lamp beds.
01

The hardest part of red light therapy is standing in front of it.

A mask or a desk panel asks you to sit still in front of it, two or three times a week, for weeks. That is the part that gets skipped.

In the Solara, a 660nm red and 850nm near-infrared panel is built in. You switch it on, sit down in the heat, and it runs while you sweat.

You're already sitting down.

Two kinds of light. You can only see one.

Red light devices for skin use two kinds of light. Visible red light, usually 630 to 660nm, is the glow you see. Near-infrared, usually 810 to 850nm, is invisible to your eye.

These LEDs do not tan you and are not UV light. The Solara uses 660nm red and 850nm near-infrared.

The studies on this page used red light two or three times a week, at the same distance, for 4 to 15 weeks.

That is a separate appointment with yourself, several times a week. On a busy evening it is the first thing to go.

Your sauna time already has a place in your week. The red light comes with it.

The Solara needs 35 by 37 inches of floor and a regular outlet. A corner of a spare room or a home gym is enough.

Same red as the Solara

In a 2025 trial in Brazil, 95 women aged 45 to 60 used a 660nm red LED mask for 21 minutes, two or three times a week, or a mask that looked the same and gave no real light. Nobody knew which mask they had.

After four weeks, software that measured wrinkle length found shorter lines between the brows and around the right eye in both red light groups, compared with the fake mask.

79.6% of the three-times-a-week group and 73.4% of the twice-a-week group were satisfied with their skin, both higher than the fake-mask group.

Two sessions a week did as well as three.

The lines around your eyes are the most studied.

A 2025 trial in Korea gave 60 adults, 56 of them women, a home mask with 630nm red and 850nm near-infrared light, or a weaker version of the same mask. Raters who did not know which mask each person had scored more improvement in crow's feet with the full-strength mask. The mask maker paid for the study.

A 2023 study gave 137 women aged 40 to 65 red 660nm light on one side of the face and amber light on the other. Wrinkle volume around the eyes was about 30% lower on both sides, with no untreated side to compare against.

A 2014 study used full-body red light beds on 136 adults. Reviewers rated wrinkles better in 69% of the red light group and 4% of the untreated group. The lamp maker funded it.

Infrared heat for the rest of you.

Sore shoulders. A stiff back. A long week.

The Solara is a full-spectrum infrared sauna first. It heats up to 158°F and plugs into a standard household outlet.

The heat helps you unwind at the end of the day and supports recovery after a workout.

Red light for your skin and heat for the rest of you, in the same session.

Heat supports recovery. It does not treat an injury.

The studies ran for 4 to 15 weeks. Harvard dermatologist Rachel Reynolds sets a longer timeline: “For the devices to be effective, they must be used multiple times a week for four to six months... It's slow and steady.”

Give it four months before you decide.

Before you start

Protect your eyes, and check your medications first.

✓Wear eye protection when you face a red light panel, and don't stare into the LEDs.
✓Ask your doctor first if you are pregnant, have a light-sensitive condition such as lupus, or a history of skin cancer.
✓Isotretinoin, lithium and some antibiotics can make your skin sensitive to light.
✓Melasma or darker skin that marks easily? Start with shorter sessions and ask your dermatologist.
✓Drink water first, skip it after alcohol, and get out if you feel unwell.

Questions.

Modestly, in some studies, mostly around the eyes. In a 2025 trial of 95 women aged 45 to 60, software measured shorter lines in two of four face areas after four weeks of 660nm light, but dermatologists scoring the photos saw no difference from a fake mask. A 2018 review of 31 trials rated the evidence for skin aging as limited. We don't promise any result.

We don't know yet. No study has tested red light inside a sauna, and we have not measured the dose that reaches your face while you sit in a Solara. The panel sits on the left side of the door and lights your body more than your face. For your face, the Nova at a set distance is the closer match to the studies.

Yes. The Solara and Pulse PRO run both together. The skin studies on this page tested red light alone, at room temperature.

The skin studies on this page used red light around 630 to 660nm, near-infrared around 830 to 850nm, or both. The Solara uses 660nm and 850nm together. No study compared them in a sauna.

In the 95-woman trial, twice a week did as well as three times a week.

The studies ran 4 to 15 weeks. Harvard dermatologist Rachel Reynolds says devices “must be used multiple times a week for four to six months.” The AAD says “not everyone sees them.”

The AAD says “In the short-term, it appears to be safe” and that research hasn't found red light causes cancer. It also says long-term effects on skin are not known. Protect your eyes and check with your dermatologist if you take light-sensitizing medication or have melasma.

It can in some people. The AAD says people with darker skin tones are more sensitive to visible light, including red light, and can get hyperpigmentation. Start with shorter sessions and ask your dermatologist.

Yes when you face a panel. Don't stare into the LEDs.

SaunaBox saunas and red light devices are intended for general wellness use only. They are not intended to diagnose, treat, cure or prevent any disease or skin condition, and nothing here is medical advice. The studies described used LED masks, panels or lamp beds at room temperature, not saunas, and none tested a SaunaBox device. Individual results vary and are not guaranteed. Speak to your doctor before starting sauna use, especially with a heart condition, if you are pregnant, or if you take medication that makes your skin sensitive to light.
