i also grew up with mosquitoes bites making my legs plastered with those ugly "10, 20 and 50 cent coins". and my legs became worse as my sister the smart aleck taught me to scrap/peel off the ugly brown patches (after we scratch our skin, then bleed and after it dries up became brown coloured patches) so that we won't walk around with the obvious brown patches lol
when i was in studying in college, my roomie saw my ugly scarred legs and she taught me to use johnson& johnson baby lotion (white and blue coloured bottle) to massage the scars area after bathing daily. i bought the biggest bottle which doesn't burn a hole in my pocket and i apply diligently throughout my first year and i was surprised it actually works very well!!
my scars have all faded now and i can wear pretty minis or shorts
maybe you can try and tell me if it works for you, but you need patience and be disciplined in order to achieve the result
