Is It Ok to Use Retinoids and LED Light Therapy Together?

Absolutely ok! Continue using your Retin-A nightly and just be sure to use daily sunscreen. There should be no problem with your LED light and the use of Retin-A.

Hope this helps.

There should be no problem using LED therapy (blinking yellow, blue or red lights} with Retin-A.  I would advise you to use the Retin-A at night since it can cause you to be more susceptible to sun. 

If you are using only LED lights and no chemical photosensitizers prior to the light exposure like we do for photodynamic therapy, then it is safe.  It may actually allow the light to penetrate more efficiently, however, I would not anticipate any risk.  However, in medicine I never say never...but again, I doubt it.

LED lights are fairly harmless rays of natural light so there should be no interaction with Retin-A (tretinoin). However, Retin-A should be used carefully in patients with sun allergies or those taking photosensitive medications.
