The only thing that can truly fix ice pick scars I hear is laser treatment which you can probably get for very cheap in Thailand. But what I have been using is tea tree oil. Not only is it cheap and magic against acne, but it gives your face a shine and hides scars a bit.

But quick warning, tea tree oil is like polio vaccine. Just like how people use polio strand to fight polio, tea tree oil is using oil to fight skin oil.
