Selective photothermolysis is a technology used in dermatological and aesthetic medicine to treat specific skin problems and conditions by heating targeted tissues 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.
functionality
- Targeted action : 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 heat generated destroys the target tissue or alters it in a way that has a therapeutic effect.
- Protection of surrounding tissue : Selecting appropriate wavelengths and pulse durations ensures 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 the target chromophore.
- Pigmentation spot removal : Age spots and other hyperpigmentation caused by melanin can be lightened or removed.
- Tattoo Removal : Tattoo pigments are treated as target chromophores, allowing the ink to be broken down and broken down by the body over the course of several treatments.
- Skin rejuvenation : Targeting superficial layers of skin can improve fine lines, wrinkles and skin texture.
Advantages
- Non-invasive : The treatment is non-invasive and typically does not require recovery time.
- Precision : High precision allows treatment of specific areas without significant damage to surrounding tissue.
- Versatility : Suitable for different skin types and conditions depending on device and settings.
Safety and side effects
Although selective photothermolysis is generally safe, side effects may occur, such as redness, swelling, blistering, and discoloration of the skin. The risks vary depending on the type of treatment, the patient's skin type and the experience of the user. It is important to choose a qualified professional for such treatments to achieve the best possible results and minimize the risk of side effects.
