How does laser hair removal work?

Laser hair removal uses concentrated light beams to target the pigment in hair follicles. The light is absorbed by the melanin in the hair and converted into heat, which damages the follicle and inhibits future hair growth. The treatment works best on dark hair and light skin, although advances in technology have made it possible to treat a wider range of skin and hair types.

How many sessions are needed for laser hair removal?

Typically, 6 to 8 sessions are required for optimal results. Hair grows in cycles and the laser can only target hair in its active growth phase, so multiple sessions are needed to reach all the follicles at the right time. Sessions are usually spaced about 4 to 6 weeks apart, depending on the area treated and the hair type.

How long do the results of laser hair removal last?

The effects of laser hair removal are long-lasting but not always permanent. After completing the recommended number of sessions, many people experience significant hair reduction that can last for months or even years. Some hair may eventually grow back, although finer and lighter, and periodic maintenance treatments may be needed to keep the skin smooth.

Why might laser hair removal not be working?

Several factors can reduce the effectiveness of laser hair removal. Lighter hair such as blonde, grey or red contains less melanin, making it harder for the laser to target the follicle, and darker skin tones may absorb more laser energy. Because the laser only works on hair in its active growth phase, more sessions may be needed, and settings that are not adjusted for your skin and hair type can also make the treatment less effective.

Is laser hair removal safe?

Laser hair removal is generally safe when performed by a trained professional. Side effects are usually mild and temporary, including redness, swelling and slight irritation in the treated area. In rare cases, improper use of the laser can lead to burns, scarring or changes in skin pigmentation, which is why it is important to choose a reputable clinic with experienced technicians.

How much does laser hair removal cost?

The cost of laser hair removal varies depending on the area treated, the clinic and the location. On average, smaller areas such as the upper lip or underarms may cost between CHF 50 and CHF 150 per session, while larger areas such as the legs or back can range from CHF 300 to CHF 600 per session. Package deals for multiple sessions are often available and can reduce the overall cost. Because it is considered a cosmetic treatment, laser hair removal is usually not covered by health insurance.

What is the best age to start laser hair removal?

There is no specific age requirement for laser hair removal, but most experts recommend starting once puberty is complete and hormones have stabilised, usually around the age of 18. Starting too early, before hair growth has fully developed, can reduce the effectiveness of the treatment.

Why are autumn and winter considered the best seasons for laser hair removal?

Although laser hair removal can be done year-round, the colder months offer distinct advantages. There is less sun exposure, and because the treatment targets pigment in the hair follicles, tanned skin can increase the risk of burns and hyperpigmentation. The colder months also allow time to complete a series of sessions before summer, and winter clothing protects recently treated, more sensitive skin from sun and pollution.
