How Long Should You Do Red Light Therapy? A Simple Guide
Too long, didn't read
- Most at-home red light masks and panels are made for short sessions, usually about 10 to 20 minutes, a few times a week.
- Your device's instructions matter more than any general rule. Longer is not better.
- Protect your eyes, and talk to a doctor first if you're pregnant, sensitive to light or take medicine that makes you sensitive to light.
- The science is still early. Treat it as a calm, relaxing ritual, not a cure.
Red light therapy is everywhere right now, from face masks to full-body panels. The most common question is simple: how long should you actually use it? Here's a clear answer, what the research does and doesn't say, and how it fits into a retreat day at Casa Del Soul in Cahuita, where every guest has use of a red light therapy mask and blanket.

What is red light therapy?
Red light therapy shines low-level red and near-infrared light on your skin. It doesn't burn or tan. Devices range from clinic machines to masks, wands, panels and blankets made for home use.
How long should a red light therapy session be?
For most home masks and panels, a session lasts about 10 to 20 minutes. Many people use them 3 to 5 times a week. Always start with the time your device's maker recommends; devices differ in strength and distance.
A few practical rules:
- Start short. Begin at the low end of your device's range and see how your skin feels.
- More isn't better. Using a device too long or too often can irritate skin. Stick to the directions.
- Be consistent. In clinics, treatment usually runs one to three times a week for weeks or months, according to the Cleveland Clinic.
How often should you do red light therapy?
A few times a week is the usual pattern for home devices. Daily use is fine for some devices and too much for others, so check yours. On a 5-day retreat, an evening session most nights is a simple routine that fits easily around the rest of the day.

What can red light therapy help with?
Research is still early. The Cleveland Clinic says there isn't yet enough evidence for most uses. The most studied areas are skin concerns such as fine lines, acne and redness, and some types of joint pain. There's no good evidence that it helps with weight loss or cellulite.
What most people notice right away is simpler: 15 quiet minutes, lying still, with nothing to do. That's why we offer it. It's a reason to slow down at the end of the day.
Is red light therapy safe?
Used as directed, short-term use appears safe. To be careful:
- Protect your eyes. Use the goggles that come with your device or keep your eyes closed, as the maker advises.
- Check with a doctor first if you are pregnant, have a skin condition, have had skin cancer, have an eye condition, or take medicine that makes your skin sensitive to light.
- Stop if your skin gets red or sore, and don't use it on broken skin.
At Casa Del Soul, red light therapy is always optional. Skip it any day you like.

How do guests use red light therapy at Casa Del Soul?
Every guest on our retreats has use of a red light therapy mask and blanket. It works best as part of an easy evening rhythm:
- Morning yoga, meditation or breathwork on the open-air deck.
- A day out in the rainforest, on the beach or on an excursion.
- A swim in the pool as the light goes down.
- A short red light session before dinner or bed, following the device's time limits.
It pairs naturally with the rest of our wellness retreat, and couples can do it side by side on a couples retreat.
Should you do red light therapy before or after a workout?
Either works for most people. Many like it after activity, when they want to wind down. On a retreat day, that usually means after the excursion or evening yoga.
What's the biggest myth about red light therapy?
That it works like a medical treatment for everything. It doesn't. Enjoy it for what it reliably gives you: a few calm minutes and a routine that tells your body the day is done. For any health concern, talk to your doctor.
