Clinic care — An acne-care method 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.
Overview & characteristics
Photodynamic therapy (PDT) is known as an in-clinic method in which a photosensitizing agent such as ALA (aminolevulinic acid) is applied to the skin and then activated by exposure to a specific wavelength of light. When the photosensitizer has accumulated in the skin and reacts to light, it is understood to generate reactive oxygen species that are thought to help regulate sebaceous gland activity. It is frequently discussed as a management option for skin that is prone to excess sebum production and recurring inflammatory blemishes.
How to manage
The photosensitizing agent is applied and allowed to absorb for a set period before light is administered, so the specific protocol and number of sessions vary depending on skin condition. After the session, the skin may become more sensitive to light for a period of time, making it important to avoid intense sunlight and to apply sunscreen diligently. For those with severe or persistent acne, consulting a dermatologist to confirm suitability is recommended rather than managing it on your own.
Good to know alongside
It is commonly mentioned in the context of acne management, sebaceous gland regulation, and light-based care. It is also compared to other light-based clinic care such as laser toning and IPL (intense pulsed light).
Everyday care tips
Photosensitivity may develop for several days following the session, so reducing light exposure by wearing a hat and applying sunscreen when going outdoors is advisable.
