How long after laser hair removal it is safe to sunbathe?

Hi Dee.  It is more important to limit your sun exposure before treatment than it is after.  If you have no secondary redness or irritation after your laser hair removal, then a couple days should be fine.  With that said, any time you tan while undergoing laser hair removal, you put yourself at higher risk for blisters or burns.  This is because tanning brings melanin to the surface of the skin.  This interferes with laser absorption in the hair, which is below the skin.To see before and after photos for Los Angeles laser hair removal patients, click on the link below.

It's recommended to limit your sun exposure when undergoing laser hair removal, limiting tanning 2-4 weeks before and after treatments. Sun protection is essential. See an expert. Best, Dr. Emer

Laser hair removal on recent sun tanned or chemically tanned skin increases the likely hood of burns due to increased melanin in the skin which can absorb more laser light. I ask that my patients refrain from sun exposure for 2 weeks before and after. I also recommend SPF 50+ sunscreen. I am a fan of zinc containing sun screens. Excellent skin moisturizer is recommended as well due to the laser and the sun drying the skin. I like dimethicone containing creams.

Hi deecue, I really don't want to be a killjoy here but sunbathing isn't a good idea, whether or not you've had laser skin hair removal. Do wait a week after laser hair removal, limit your sun exposure and wear sunblock.However, if you intend to have a laser hair reduction treatment when you get back and presumably tanned, be aware that you are increasing your danger of having laser burns.All the best, Justin Harper, M.D.

Hi Dear
Keep away from sun 4-6 weeks before and after any Laser treatment, because it takes our skin to generate one layer of skin (100 microns). 
Thank you
