Laser technology is simply much more effective, and achieves substantially better results than IPL.
1. Each laser pulse takes a fraction of a second and can treat several hairs at a time.
2. Lasers are safe for all skin colours, whereas IPL can cause burns on darker skin tones.
3. Lasers are far more precise, and can selectively target dark, coarse hairs while leaving the surrounding skin undamaged.
4. Laser machines produce a single wavelength of light (pure light consisting of one single colour and form), which has a very concentrated beam and specific target (the melanin in hair follicle). Whereas IPL light scatters and can not target the follicle as laser does in its one shot.
Only a knowledgeable skin care practitioner can adjust Laser settings to suit your specific skin tone and hair colour.
