How Many Days After Fraxel Do I Need to be Strategic about Applying Sunblock?

  After a fractional laser procedure, I think waiting 7 days before using sunblock and Retin A would be reasonable.

Sunblock needs to be part of your daily regimen indefinitely, and Retin-A can be used after 10-14 days or longer if you are not resolved.  The redness should be gone or nearly gone.  If you test a small area, your body will tell  you when are ready.

The idea of Fraxel laser resurfacing is to either remove sun damage or reverse the effects of aging on the skin.  Everyone knows that the worst thing for your skin is the sun!  It is important to always use sunscreen to protect your skin, especially after Fraxel.  Depending on your skin sensitivity, I advise waiting two weeks to one month after Fraxel to re-start Retin-A after treatment.

Fraxel laser skin resurfacing helps to reverse the effects of aging of the skin by building new collagen. Ultraviolet light, esp., UVA accelerates the aging changes, so I ask my patients to protect with sunblock daily, regardless of any laser treatment.

Studies have shown that Retin-A used before and starting back after the Fraxel benefits healing, new collagen production, and controls the pigment better than without Retin-A. I usually start my patients back on Retin-A after a week following Fraxel restore, but too much, too soon can be irritating. So return to the Retin-A slowly, and monitor the progress. 

You should use sunscreen EVERYDAY, even if it is cloudy outside UV rays penetrate even through windows.  As for getting back to using Retin-A, you may start back after 5 to 7 days.

Hope this helps.
