Summary

This study tested a gel called SGX302, which is activated by visible light, on 15 people with mild-to-moderate plaque psoriasis. The goal was to see if it could clear or nearly clear skin lesions over 18 weeks. The treatment is applied to the skin and then exposed to light, aiming to control the disease without long-term medication.
