Photodynamic therapy (PDT) is an advanced treatment in dermatology and cosmetology, utilizing light-sensitive agents to target and treat various skin conditions. When combined with specific wavelengths of light, these agents produce a reaction that destroys abnormal or damaged skin cells. PDT is highly effective in treating conditions such as acne, sun-damaged skin, actinic keratosis, and even certain types of skin cancer. Its non-invasive nature, combined with precision targeting, makes it a popular option for patients seeking minimal downtime and lasting results. Additionally, PDT is used in cosmetic procedures to rejuvenate the skin, reduce wrinkles, and improve overall skin tone.
