Favre-Racouchot syndrome, also known as solar or senile comedones and nodular elastosis with cysts and comedones, is a disorder of the skin resulting from chronic exposure to the sun. After decades of sun exposure, small cysts and large blackheads form on the face and neck. The lesions are usually seen on the face (typically on the temples, cheeks, and periorbital area) of elderly adults.

It is more common in patients with a heavy smoking history and may be accompanied by other signs of skin damage secondary to chronic sun exposure (for example, deep wrinkles). Other types of radiation exposure also increase the risk. Middle-aged men with Fitzpatrick skin types I and II are more commonly affected than women and individuals with darker skin colors. Because the disease is benign, any treatment other than sun protection measures is for cosmetic purposes only.

As this condition is acquired secondary to chronic sun exposure, it is not commonly seen in children or young adults, although cases have been reported in patients in their second decade of life.
