Methoxsalen is a medication commonly used in the treatment of skin diseases. It belongs to the psoralen class and is used as part of a treatment method known as phototherapy or PUVA (psoralen and ultraviolet A) therapy. Methoxsalen makes the skin more sensitive to ultraviolet A light. During treatment, methoxsalen is taken or applied to the skin, followed by exposure to UVA light. Methoxsalen can alleviate the symptoms of these skin diseases by regulating rapid cellular growth and modifying immune system responses. However, methoxsalen and PUVA therapy can cause skin sensitivity and increase the risk of skin cancer, so it should be used under the supervision of a doctor and with a prescription.
