UVB light, in particular, has immunosuppressive effects, which can help slow down the overactive immune response responsible for the rapid skin cell growth in psoriasis.

This helps in reducing inflammation and scaling.

LED light therapy can slow down the excessive growth of skin cells. It promotes a more normal growth pattern and shedding of skin cells, leading to a reduction in the formation of thickened plaques.

UVB light has anti-inflammatory properties, helping to alleviate redness, swelling, and itching associated with psoriasis lesions.

Exposure to UVB light stimulates the production of vitamin D in the skin. Vitamin D is known to have immune-modulating effects, and its deficiency has been linked to autoimmune conditions, including psoriasis.

LED light therapy allows for targeted treatment, focusing specifically on affected areas, which minimises exposure to healthy skin.

This targeted approach can enhance the effectiveness of the therapy while reducing the risk of side effects.
