Active clinical trials for "Photosensitivity Disorders"

This study will evaluate the safety and efficacy of the Excel V 532 nm KTP laser for the treatment of dyschromia of the neck and/or chest (poikiloderma of Civatte).

Topical treatment of mild to moderate actinic keratosis located on the face and head with Solaraze® is known to be a safe and efficient treatment option. However, it is unclear if an expansion of the treatment period to 6 months will increase the rate of complete responses. Therefore the investigators will evaluate the efficacy and safety of the treatment of actinic keratosis with Solaraze® applied twice daily to the face and head over 3 or 6 months of treatment.

This is a 6-visit, single-center, non-dispensing, randomized, single-masked, 5×5 crossover study. Subjects will participate in 6 scheduled over the duration of approximately 10.5 months.

This study evaluates the potential for induction of photosensitization by P-3074 0.25% finasteride cutaneous solution compared to that of placebo vehicle cutaneous solution and a negative control (0.9% sodium chloride, NaCl)

The clinical trial is designed as a national, prospective, single-center, double-blind, parallel group, randomized, controlled, interventional trial to investigate whether a therapy with HCT compared with placebo can affect dermal photosensitivity and DNA stability.

To evaluate the skin irritation and sensitization potential of a cosmetic facial product, under exaggerated conditions of use with controlled product application and under supervision of a dermatologist.

The purpose of this study is to determine whether 5-FU infusion (Microinfusion of Medicine Percutaneously - MMP) is effective for Idiopathic Guttate Hypomelanosis (IGH) repigmentation compared to conventional Microneedling. MMP is a procedure done with tattoo devices using medication in place of ink.

Determination of collagen, pigment and haemoglobin content of sun exposed and sun protected skin by Siascopy. Immunocompromised patients (for more than seven years) compared to immunocompetent patients. Trial in the field of transplantation / xenotransplantation

After a head injury, many people find that exposure to light causes them increased discomfort. By measuring how the pupil in the eye constricts to flashes of red and blue light, this study will investigate whether this phenomenon is due to a change in the eye's sensitivity to light.
