Good morning sir,I am sravan,from india.actually i was very fair and handsome.For acne vulgaris i applied excessive hydroquinone,because of that i got pigmentation over the face.to treat that doctors gave laser treatment ND YAG ,Q switch,and my pigmentation is still worsenhat should i do.I am a junior scientist in India.My age is 24 years.
There is a condition called ochronosis which is due to excessive hydroquinone use or excessively high percentage of hydroquinone. This is a very rare problem however. The treatment you had for this pigmentation, q-switched Nd:YAG laser, possibly worsened the pigmentation further as it stimulated new pigmentation production in the skin. This is usually the result of excessively high settings used on the laser. As I cannot see your skin, I would advise that you return to the place of your treatment, and see if they can find you another alternative. Maybe a different topical skin lightener might be better?
