Laser therapy is a treatment method that is widely used in various fields of medicine – from physical therapy, physiotherapy, and rehabilitation to cosmetology, aesthetic medicine, dermatology, and dermatosurgery.
Laser therapy is a modern method of tissue treatment and regeneration using light energy. It is based on forced radiation emission, i.e., the precisely controlled application of laser radiation to selected areas of the patient's body. The light beam emitted by the device at a specific wavelength (nm) penetrates deep into the skin, producing therapeutic effects such as collagen stimulation, anti-inflammatory, analgesic, and biostimulation effects.
In aesthetic medicine, dermatology, and dermatosurgery, laser therapy is used for the non-invasive treatment of various skin lesions and aesthetic defects. Laser treatments enable, among other things, the removal of discoloration, closure of blood vessels, treatment of scars and stretch marks, as well as improvement of the overall structure and firmness of the skin. In dermatological surgery, fractional laser allows for precise removal of skin lesions with minimal risk of scarring. Importantly, a properly selected wavelength and laser power allow for effective treatment even in the eye area, while ensuring complete patient safety (protective glasses with side shields are required).
Laser therapy involves applying a special probe or laser head to the skin, which emits a focused, monochromatic beam of light. The laser head touches the patient's body, directing energy precisely to the problem area. Depending on the type of laser and settings (such as wavelength or power), it is possible to achieve a biostimulating, therapeutic, or destructive effect, e.g., in the case of wart or scar removal. Spot laser therapy is also used in the case of musculoskeletal disorders, injuries, and laser rehabilitation.
Indications for laser therapy include, among others:
Although laser therapy is a safe and modern method widely used in dermatology and aesthetic medicine, there are situations in which the possibility of undergoing therapy must be ruled out for health reasons. Contraindications include:
Contraindications include:
Qualification for laser treatments should always be carried out by a doctor or experienced specialist who will assess the condition of the skin, review the patient's medical history, and tailor the type of therapy to their individual needs.
After laser therapy, temporary side effects may occur, which usually disappear spontaneously within a few days. These include:
To minimize the risk of complications and enhance the therapeutic effect, patients should follow the specialist's recommendations after laser treatment:
Proper post-treatment care is extremely important for the quality of skin regeneration and the durability of results. Although laser therapy is non-invasive, it has an intense effect on the deep layers of the skin, which is why following the recommendations affects the final therapeutic effect and safety of the treatment.
Laser therapy has a beneficial effect on the appearance and condition of the skin. Laser treatments can achieve the following:
In some cases, it is recommended to perform a series of laser therapy treatments in order to achieve better therapeutic results. Laser therapy is a minimally invasive procedure, often requiring no recovery period, which allows the patient to quickly return to their daily activities.
