Photodynamic therapy (PDT) is a non-invasive treatment that uses a photosensitizing agent and a special light source to selectively destroy abnormal or damaged skin cells. It can be used to treat a variety of skin conditions, including pre-cancerous actinic keratoses or even some superficial skin cancers. It can even be used to treat inflammation associated with acne!

How Does PDT Work For Sun Damage?

During a PDT treatment for sun damage such as actinic keratoses or superficial skin cancers, a photosensitizing agent is applied to the skin, where it is absorbed by the damaged cells. After a short incubation period, a special light source is used to activate the photosensitizer, which then generates oxygen molecules that destroy the damaged cells. 

How Does PDT Work For Acne?

When PDT is used to treat acne, the oxygen molecules that are created destroy the bacteria that contribute to acne breakouts. Additionally, PDT can help to reduce the size of the sebaceous glands, leading to less oil production and fewer breakouts.

Overall, PDT is a safe and effective treatment option for patients with sun damage and acne. It can help to reduce the appearance of sun damage and improve the overall texture and tone of the skin. For patients with acne, PDT can help to reduce breakouts and improve the clarity of the skin.
