Laser depilation

Laser depilation This is a method of permanent hair reduction that involves the use of a laser light beam. The light energy penetrates the epidermis and is absorbed by the melanin in the hair follicle, leading to thermal damage to the follicle and a gradual reduction in hair growth. This process does not remove the hair mechanically, but affects its growth structure, weakening its ability to regenerate in subsequent cycles.

Laser depilation It is performed as a cosmetic procedure on various parts of the body, for both women and men. It most commonly involves the legs, underarms, face, back and bikini line.

Laser hair removal – how it works

Laser depilation It is based on the phenomenon of selective photothermolysis. This means that the energy from the laser light is selectively absorbed by melanin, allowing for precise targeting of the hair follicle whilst minimising the impact on the surrounding skin tissue.

As a result of energy absorption, the energy is converted into heat, which causes damage to the structures responsible for hair growth, including the matrix cells and the hair papilla. This damage is irreversible within active hair follicles.

The effectiveness of the treatment depends on the hair growth cycle. The best results are achieved during the anagen phase – that is, the active growth phase – when the hair is firmly attached to the dermal papilla. As hairs are in different phases at the same time, a series of treatments is necessary.

Laser hair removal – applications

Laser depilation It is used to achieve long-term hair reduction and to minimise the dermatological problems associated with traditional hair removal methods.

This method is particularly effective for treating ingrown hairs, folliculitis and recurrent skin irritation following shaving or mechanical hair removal.

In clinical practice, it is also used in cases of excessive hair growth caused by hormonal or genetic factors, where standard hair removal methods are insufficient.

Laser hair removal - contraindications

Contraindications to laser depilation These include, amongst others, pregnancy, the breastfeeding period, a recent tan, the use of photosensitising medicines and substances, active skin infections, certain dermatological conditions, a tendency to develop keloids, and isotretinoin therapy.

In addition, contraindications may include blood clotting disorders, the use of anticoagulants, epilepsy, cancer, active autoimmune diseases and certain endocrine disorders. In certain cases, the presence of electronic devices, such as a pacemaker, may also be a factor, depending on the treatment area.
