2. Diode Laser: Emitting a wavelength of 810-810 nanometers, diode lasers are flexible and can be used on a huge range of pores and skin types. They are regularly used for smaller regions just like the face and underarms.
3. Nd:YAG Laser: This laser has a wavelength of 1064 nanometers and is ideal for individuals with darker skin tones, as it's miles much less possibly to cause hyperpigmentation or burns on the pores and skin. It is a great preference for hair removal on the face and body.
4. Ruby Laser: Emitting a 694-nanometer wavelength, the ruby laser is powerful for those with fair pores and skin and darkish hair. However, it has a smaller spot length and might require extra time for larger regions.
Safety and Considerations
While laser hair elimination is commonly considered secure, there are some vital considerations to maintain in mind:
