The machine already preset recommended safe parameters. The operator can directly use default parameters to do treatment.

The default parameters are safe settings, but they are not always the best settings for every customer. The most suitable parameters depend on the customer’s skin type, hair color, hair thickness, and treatment area. Start with safe settings and gradually adjust the energy, pulse width, and frequency according to the customer’s response and treatment results. 

Suitable parameters usually cause a warm feeling, slight redness, and mild swelling around the hair follicles. The customer should feel comfortable without strong pain or excessive heat sensation.

Clinical Endpoint means the skin reaction after laser treatment.

A good endpoint is slight redness (erythema) and small swelling around the hair follicles(perifollicular edema). It shows that the laser energy has reached the hair follicles effectively. 

After treatment, the hair will start to fall out in about 1–3 weeks. With several treatments, the hair will become thinner, grow slower, and the hair density will be reduced. 

Most customers need 3–5 sessions for optimal hair reduction. The exact number depends on the customer’s hair type, skin type, and treatment area.

You need to change water filters for the machine once every year. No need for other regular inspections. Please clean the machine and handpiece after use.
