Can You Use Red Light Therapy With Retinol or Tretinoin?

Short answer: Yes. Many people use red light therapy and retinoids (retinol, tretinoin) in the same routine. The key is sequencing: do red light on clean, bare skin, then apply your retinoid afterward.

How they fit together

Retinoids are a topical skincare ingredient, and some people also add red light to their routine. Because retinoids can cause dryness, redness, and irritation, especially when you're starting out, many people introduce one step at a time and pay attention to how their skin responds. Our guide on how often to use red light therapy explains how product pages describe session timing.

How to combine them safely

• Red light first, on bare skin. Light works best with nothing in the way, so cleanse, do your red light session, then apply retinol or tretinoin afterward.
• Don't apply your retinoid right before a session. There's no benefit, and you want the light reaching skin directly.
• Start slow. If you're new to retinoids, introduce them gradually so you're not stacking too much irritation at once.
• Moisturize and use daily SPF. Retinized skin is more sun-sensitive. Sunscreen is non-negotiable.

What if my skin gets irritated?

Red light therapy itself uses no UV and doesn't burn, but retinized skin can be more reactive in general. If you notice stinging or persistent redness, separate the two (for example, red light in the morning and your retinoid at night) and dial back retinoid frequency until your skin adjusts.

Which device for a skin routine?

A hands-free LED face mask is an easy way to fold red light into a nightly routine. The LX500 and LX300 face masks deliver red and near infrared light to the face in about 10 minutes. You can compare them in the masks collection or read our guide to choosing a red light therapy mask. FDA 510(k) clearance applies to select devices, including these two face masks, for specific, limited uses on the face only.

Frequently asked questions

Should I apply retinol before or after red light therapy?
After. Do red light on clean, bare skin, then apply your retinoid.

What if retinoids irritate my skin?
Retinoids can cause dryness or irritation on their own. If your skin is reactive, space the two steps out and check with your dermatologist.

Can I do both every day?
Many people do, but if your skin is reactive, space them out (light in the morning, retinoid at night) and build up gradually.

If you use prescription tretinoin or have a skin condition, check with your dermatologist. This is educational, not medical advice. See our safety guide.
