UV light therapy, also known as phototherapy, is a common treatment for psoriasis. It involves exposing the skin to ultraviolet (UV) light to reduce the symptoms of psoriasis. While UV light can be beneficial for psoriasis, it is important to approach it with caution.
Tanning beds emit both UVA and UVB light, which are similar to the types of light used in medical phototherapy. However, tanning beds are not recommended for treating psoriasis for several reasons:
Inconsistent and uncontrolled dosage: Tanning beds may not provide consistent and controlled dosages of UV light, which is crucial for effective and safe treatment. Medical phototherapy is carefully administered by healthcare professionals who can adjust the dosage based on an individual's response and skin type.
Higher UVA exposure: Tanning beds tend to emit a higher percentage of UVA rays compared to UVB rays. UVB light is more effective for treating psoriasis, whereas UVA light is less effective and can increase the risk of skin damage and aging.
Increased risk of skin cancer: Prolonged exposure to UV radiation from tanning beds can significantly increase the risk of developing skin cancer. Psoriasis itself already slightly increases the risk of skin cancer, so it is important to avoid unnecessary risks.
If you have psoriasis and are considering light therapy, it is best to consult with a dermatologist or healthcare professional who can provide appropriate guidance. They can recommend safe and effective treatments that utilize controlled UV light sources, such as medical phototherapy units, to manage your psoriasis symptoms while minimizing potential risks.
