They look like hypopigmentation white spots? Cannot tell from the pic. Please goto the below link in my signature called faq and the skin section hypo pigmentation. IF that does not work you need to goto a derm.

2 months before I was having the same scars on my neck. I was so worried. I asked my friend who is a doctor and she told me about a skin cream Cysteamine. I used it just for 3 weeks and all my scars were gone. I suggest you should try it.

Cysteamine is a skin lightening agent so may be beneficial for dark spots or hyperpigmentation but there is no data to suggest any benefit for scars themselves.
