This is very important to understand. Hair goes through 3 stages of development. Typically in the anagen stage, the hair will respond more effectively to treatment. At any given time, only one third of human hair is in the anagen stage. For this reason, it is necessary to treat an area at least 3 times with the treatments spaced approximately 6 weeks apart in order to see the best and longest lasting results. Darker hair will respond better, but both dark and light hair may need up to 5 treatments for maximum response and the best long-term results.

An upper lip and chin can be done in 5 to 10 minutes. Underarms or bikini lines usually take 15 to 20 minutes. Legs and backs take longer. Very often, follow-up treatments are shorter (and less expensive) because there is much less hair to treat.

The laser treatment may feel like a mild sting for a fraction of a second. It has a built-in cooling tip that not only helps to protect the skin but also helps to minimize the discomfort.

The Cutera CoolGlide Laser is FDA-approved for use in types I to VI skin, that is, from the whitest white to the darkest dark. Care is taken with the darker shades of skin, but excellent results can be obtained in black skin.

Treatment results may vary among patients. The Altus CoolGlide Laser is cleared by the FDA for Permanent Hair Reduction. The FDA defines permanent hair reduction as the long term, stable reduction in the number of hairs re-growing after a treatment regime.
