An acne treatment applying a photosensitizer then irradiating with specific light to destroy sebaceous glands
Photosensitizers like ALA accumulate in sebaceous glands and are activated by light to selectively destroy overactive glands.
Main causes & characteristics of Photodynamic Therapy (PDT)
Photodynamic therapy (PDT) is known as a procedure in which a photosensitizing agent such as ALA is applied to the skin and then exposed to light of a specific wavelength. When the accumulated photosensitizer reacts to light, reactive oxygen species are said to be generated, which are thought to be involved in regulating sebaceous gland activity. It is mentioned as a treatment option for skin prone to excess sebum production and recurring inflammatory breakouts.
Managing Photodynamic Therapy (PDT)
Since the photosensitizer is applied before the session and must be allowed time to absorb before light exposure, the procedure and number of sessions vary depending on skin condition. After the treatment, the skin may become more sensitive to light for a period, so avoiding strong sunlight and applying thorough sun protection is advisable. If acne is severe or recurring, consulting a dermatologist to confirm suitability is recommended rather than self-managing.
