How It Works on Skin and Muscle Updated October 20, 2026 · 3 min read Image: Woman receiving red light therapy for skin and recovery at iCRYO South Jordan, UT (https://icryo-southjordan-ut.com/blog-images/what-is-red-light-therapy-south-jordan-ut.webp) What if one of the most relaxing parts of your week also supported your skin, muscles and recovery? That's the appeal of red light therapy at iCRYO South Jordan (https://icryo-southjordan-ut.com/services/red-light-therapy). It's gentle, painless and takes just minutes. Here's what red light therapy is, how it works and who it's for. ## What Is Red Light Therapy? Red light therapy, also called **photobiomodulation**, exposes your skin to low-level red and near-infrared light. Unlike UV light from the sun or tanning beds, these wavelengths **don't damage skin**. Instead, they're absorbed by your cells and used to support normal function. ## How Red Light Therapy Works Here's the simple version. ### Light gets absorbed by your cells Red and near-infrared light penetrate the skin. Inside your cells, they're absorbed by the **mitochondria**, the structures that produce cellular energy. ### Cells get an energy boost Research suggests this light helps mitochondria work more efficiently, supporting the energy your cells need to repair and renew. ### Different wavelengths, different depths - **Red light** acts mostly on the skin - **Near-infrared light** penetrates deeper into tissue and muscle ## What People Use Red Light Therapy For - **Skin health:** tone, texture, fine lines and collagen support - **Muscle recovery:** after workouts and long days outdoors - **Joint comfort:** many people use it for stiff, achy areas - **General wellness:** a relaxing, restorative routine See the full list in Red Light Therapy Benefits (https://icryo-southjordan-ut.com/blog/red-light-therapy-benefits). ## What a Session Is Like 1. **Arrive and prep.** Clean skin works best. 2. **Protect your eyes** with provided eyewear if recommended. 3. **Relax** in front of or inside the red light device. 4. **Enjoy** gentle warmth for the length of your session. 5. **Go about your day.** No downtime. ## Who Should Talk to Us First? Red light therapy is gentle, but let us know if you are pregnant, are sensitive to light, take medications that increase light sensitivity or have a history of skin cancer. ## In-Clinic vs. At-Home At-home panels are everywhere.

Red light therapy uses red and near-infrared wavelengths that don't tan or burn. **Myth: "Any red light bulb will do."** Fact: Results depend on specific wavelengths and enough power to reach your cells. Professional devices are designed for that. Read In-Clinic Red Light Therapy vs. At-Home Panels (https://icryo-southjordan-ut.com/blog/red-light-therapy-clinic-vs-at-home). **Myth: "One session will transform your skin."** Fact: Red light therapy works through gradual processes like collagen production. Consistency over weeks delivers results. **Myth: "Red light therapy replaces sunscreen."** Fact: It supports skin repair, but it doesn't protect against UV. Daily SPF is still essential, especially at Utah's altitude.
