Do I have to quit Retin A before Thermage or IPL? Can I start using it immediately afterward?
Using Retin-A with Thermage or IPL?

No Need To Quit
There would be no need to quit.
Both processes occur below the epidermis. Since the relevant part of Retin A's effects occurs in the epidermis--some thinning of the stratum corneum, the horny dead cell layer of the skin,--there should be no problem with either IPL or Thermage.
