The Skin Theory by Dr. Guruvani Ravu | Dermatologist on Instagram: "Noticed any tiny white spots on arms or legs? Many people mistake them for vitiligo, but we explain that this condition is actually called idiopathic guttate hypomelanosis - a harmless condition caused by mild pigment loss from aging or sun exposure. It’s completely safe, asymptomatic, and non-contagious. #skintheory #idiopathicguttatehypomelanosis #skinissues #skincare #skincareroutine"
