Favre–Racouchot syndrome is a solar elastotic disorder consisting of multiple open comedones that occurs in skin damaged by sunlight, especially under and lateral of the eyes.

The comedones are widened openings for hair follicles and sebaceous glands filled with material.

At least in one instance, the occupational exposure to the UVA light of the sun (UVB is blocked by many car windows) resulted in skin destruction on one side of the face.

[2] Microscopically, Favre–Racouchot displays multiple dilated follicular cysts/milia and open comedones with severe solar elastosis in the background dermis.

[3] Favre–Racouchot syndrome is named after the French dermatologist Maurice Favre and his pupil Jean Racouchot (1908-1994).
