At TRNR Skin, we’re all about helping you achieve your healthiest, most radiant skin — and red light therapy is one of our favorite tools for doing just that. Whether you’re already a red light devotee or just starting to explore its benefits, we know there are a lot of questions out there. That’s why we’re diving into the most frequently asked questions we hear about this powerful skincare technique.

What Is Red Light Therapy?

Red light therapy (RLT) is a non-invasive treatment that uses low-wavelength red light to penetrate the skin. It’s designed to stimulate collagen production, improve cellular function, and reduce inflammation. The result? Smoother skin, less redness, and a serious glow.

How Often Should I Use It?

Consistency is key. We recommend using red light therapy 3–5 times a week for best results. Make it a part of your evening routine — your skin will thank you.

Can I Use It with Other Products?

Yes! Red light therapy works well alongside your existing skincare routine. In fact, pairing it with antioxidant-rich serums can help amplify results. Just make sure to apply products after your session to get the full effect of the light on bare skin.

Is It Safe?

Absolutely. Red light therapy is FDA-approved and safe for all skin types. There’s no downtime, no pain, and no UV damage — just healthy skin and a relaxing moment of self-care.
