Laser Hair Removal Systems At Clinics - Ruby Laser (694 nm)

Ruby laser is the original and first system of laser hair removal treatment. It having been invented in 1960 and approved for hair reduction by the FDA in 1997. Today, Ruby is an older technology and has been abandoned gradually.

Ruby deeps red color at 694 nm is highly absorbed by the melanin pigment in hair, making it an excellent choice for fine and light hair. However, melanin in the skin absorbs the Ruby laser very effectively too, so there's a high risk of burns or changes to pigmentation when used on darker skin tones including tanned skin, it is only really can suitable for white skin. Because of this limitation, slow repetition rate, and relatively small spot size, Ruby lasers have become less popular for laser hair reduction in recent years.

The slow repetition rate with the Ruby laser is designed to provide more comfort for the patient, patients would have experience less pain. Unless you are very afraid of pain, otherwise Ruby is not recommended.
