IPL Devices (Hair Removal)

An IPL device fires broad spectrum light through a filtered window onto skin. Pigment in the hair shaft absorbs it, converts it to heat, and that heat travels down to the follicle. Intense pulsed light is the full name. The word worth holding onto is pulsed, since these send many short flashes rather than one continuous beam.

Only hair in its active growing phase sits firmly enough in the follicle for that heat to matter, and roughly a fifth to a third of the hair on any patch of body is growing at once. That single fact sets the whole schedule. Makers ask for a session every one to two weeks across eight to twelve rounds, then a maintenance flash every four to eight weeks, because hairs that were resting during round one are growing by round four. Anyone judging a device after three sessions is judging it far too early.

Contrast is what makes this work, and it rules some people out. Dark hair on light to medium skin gives a flash something to aim at. White, gray, red and pale blonde hair carries too little pigment to heat. The device does nothing at any setting and persistence will not change that. On the deepest skin tones the skin itself absorbs the energy meant for the follicle, which risks burns and lasting pigment change, and most home devices carry a skin tone sensor that simply refuses to fire. None of that is a dead end, since clinics run wavelengths and settings a home unit does not carry, and electrolysis works regardless of hair color.

Shave the area first and never wax or epilate before a session, because the target has to still be in the follicle. Home devices run far weaker than clinic lasers. The accurate claim on the box is permanent reduction, meaning fewer and finer hairs rather than bare skin. Cartridge Razors and Electric Shavers stay in the routine right through the course. Compare devices on energy per flash, window size in square centimeters, and total flashes against the area you intend to cover, since a small window over two legs turns every session into a twenty minute chore.

Wear the supplied eye protection and never flash over tattoos, dark moles or freshly tanned skin. Patch test one spot at the lowest setting and wait 24 hours. Wipe the window between sessions, as burnt hair residue blocks light and heats the glass.
