LED (low level light) treatments and Sculptra injections produce new collagen through totally different mechanisms. There is no scientific evidence to suggest that LED therapy will worsen lumps.
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.

I'm sorry but LED alone is not effective on Actinic Keratosis. Combing the light with Levulan will treat sundamaged skin that has precancerous lesions like Actinic Keratosis.
Hope this helps.
