Very simple . First of all to solve any problem you have to go to the root of problem . According to the picture I still can see fresh wounds , so do whatever to avoid mosquito bites from now on , no point doing laser if the problem hasn't been solved .

For your case , its common and mild , don't get too upset <3
Those black spot appear on your legs are called hyper pigmentation , its due to over production of melanin in ur skin after the wound heals.
Go to your pharmacy nearby and look for a topical medication that contain ''hydroquinone'' either 2% or 4 % will be good enough.

Hydroquinone is a type of chemical that prevent the skin from producing melanin therefore those spots will go away after a months of treatment .
Follow the instruction and apply accordingly

But please note that upon applying this topical , your skin will get sensitive to sun lights , so please wear clothes that covers your leg when you're in outdoor even if its evening to avoid sunlight.

The treatment should lasts for 1 months .

Good luck , feed back your results to me , and ask me if you have any questions .

And please don't visit any skin specialist or go for laser treatment , its not necessary.
