how to get rid of mosquito bites ?

[Pendu]

I got bitten a lot in India over a year ago and I still have great big round scars. I don't usually get fussy about these kind of things but they look awful, like I have chicken pox or something all over my arms. What will get rid of them? Doesn't matter how extreme because they are really hideous

You need to exfoliate them daily with a scrub or loofah to get rid of dead skin and encourage new skin which will have a lighter pigment. Then moisturise with a heavy duty cream. Bio oil is supposed to be good or Shea butter.
Any cream that contains vitamin c or alpha hydroxy acid will help as it removes the top layer of skin and encourages new skin growth.

In the meantime, could you cover the worst ones with a dab of concealer?

Maybe also try bio oil?
