Hello.

I also have a Braun Silk expert Pro 3 IPL, but I don't find it effective. I used it under the pubis, the hairs are grilled, it smells like pork, but they are still there.

John uh no I'm Jennifer  (Humor)

Hi Jennifer,
Did you shave first? As that is the most effective way to use ipl and laser therapy. The shorter the hairs are, more energy from the light can travel down the hair to damage and hopefully destroy the hair follicle.

Yes of course

The hairs are 3 to 7mm.
