Last night mark wasn't there and in the morning in maroon colour a big mark is formed on the nose. It's just in one over night. Am using adapalene gels for my acne pimples treatment since 6 months and never had side affects with that. I don't have any allergy also. Now I don't know the reason why it is formed. Can you please tell me the reason and lead me whether to consult a dermatologist or a normal doctor or just wait so that it will vanish by itself. Even if I consult a doctor how many days will it take to be gone completely because am a working woman and the mark is pretty noticeable on the face 😔
