Selective photothermolysis is a technology used in dermatological and aesthetic medicine to treat specific skin problems and conditions by selectively heating tissue with light energy. The principle is based on using light of a specific wavelength that is absorbed by specific chromophores (color-producing molecules) in the tissue without damaging surrounding tissue.
How it works
- Targeted effect : Selective photothermolysis targets specific chromophores in the body, such as melanin in the hair, hemoglobin in the blood vessels, or tattoo pigments.
- Absorption : The target chromophore absorbs the light and converts it into heat. The generated heat destroys the target tissue or alters it in a way that has a therapeutic effect.
- Protection of surrounding tissue : By selecting suitable wavelengths and pulse durations, it is ensured that only the target chromophore absorbs the energy and the surrounding tissue remains undamaged.
Applications
- Hair removal : By targeting melanin in the hair follicles, unwanted hair can be permanently reduced.
- Treatment of vascular lesions : For example, spider veins, hemangiomas and rosacea can be treated by using hemoglobin as a target chromophore.
- Removal of pigment spots : Age spots and other hyperpigmentation caused by melanin can be lightened or removed.
- Tattoo removal : Tattoo pigments are treated as target chromophores, which allows the ink to be broken down and eliminated by the body over several treatments.
- Skin rejuvenation : By specifically treating superficial skin layers, fine lines, wrinkles and skin texture can be improved.
Advantages
- Non-invasive : The treatment is non-invasive and usually requires no recovery time.
- Precision : High precision enables the treatment of specific areas without significant damage to the surrounding tissue.
- Versatility : Suitable for different skin types and conditions, depending on the device and settings.
Safety and side effects
Although selective photothermolysis is generally safe, side effects such as redness, swelling, blistering, and skin discoloration can occur. The risks vary depending on the type of treatment, the patient's skin type, and the practitioner's experience. It is important to choose a qualified professional for such treatments to achieve the best possible results and minimize the risk of side effects.
