I am a 22 year old man. I have ugly large dark patches on my face. Before I had these patches, some 3-4 weeks ago, I used to wash my face and body with dettol. I used to use this soap 2-3 times a day(for bathing etc..). I felt some minor burning sensation on my cheeks but didn't pay too much attention to it. Then one day I noticed that the dark patches just appeared. I went to the derm and he said that it was the result of prolonged exposure to the sun and that i had dry skin. Thus I didn't tell him about the dettol stuff. What I want to know is that, are dark spots caused by sun similar to the dark spots caused by dettol? The derm prescribed stieva-A 0.025 and eldopaque cream. My skin has become sensitive with these creams and the patches have gone darker and larger. There is an everlasting burning sensation. What to do should I go to him again? stop using the creams?
