Laser epilation, also known as laser hair removal, is a cosmetic treatment method that uses laser light to permanently reduce or remove unwanted body hair. The laser aims at that Melanin (the dye) in the hair, whereby the light energy is converted into heat, which then... Hair follicles harms. This process slows or stops new hair growth without damaging the surrounding skin.
functionality
- Preparation : Before treatment, it is recommended to clean the skin and avoid tanning, as the laser relies on the contrast between skin color and hair color. The hair should be shaved shortly before treatment so that the laser can act directly on the hair follicle without the hair length absorbing the energy.
- Procedure : During the treatment, a laser device is placed on the skin. Depending on the type of device and the treatment area, a cooling device or cooling gel may be used to protect the skin and make the treatment more comfortable. The laser emits precisely controlled pulses of light that are absorbed by the melanin in the hair and converted into heat, which damages the hair follicle.
- Aftercare : After treatment, the skin may be red and slightly irritated, similar to a mild sunburn. Cooling lotions or gels can help relieve these symptoms. Direct sunlight should be avoided in the weeks following treatment and a sunscreen should be used to protect treated skin.
Advantages of laser epilation
- Long-term results : Many users experience a significant and lasting reduction in hair growth after several treatments.
- Precision : Lasers can target dark, coarse hair without damaging the surrounding skin.
- Speed : Each laser pulse can treat many hairs at the same time in a fraction of a second. Small areas like the upper lip area can be treated in less than a minute, while larger areas like the legs take longer.
Disadvantages of laser epilation
- Cost : Laser epilation can be expensive, especially if multiple treatment sessions are required.
- Multiple sessions required : Multiple treatment sessions are usually necessary for optimal results as hair needs to be treated at different stages of growth.
- Effectiveness depends on hair and skin type : The treatment is most effective on people with light skin and dark hair. However, advances in laser technology mean there are now options for people with darker skin.
Risks and side effects
- Skin irritation : Redness and swelling are common but usually resolve within a few hours.
- Pigment changes : The treatment can lead to darkening or lightening of the treated skin areas, especially if used incorrectly or when treating tanned skin.
- Less common risks : In rare cases, blistering, scarring or other skin changes may occur.
The decision to undergo laser epilation should be made after careful consideration of the pros and cons and advice from a qualified professional in order to achieve the best results and minimize risks.
