Best way to get rid of acne scars/hyperpigmentation for fair skin?

No. It won't make the slightest difference. The pigmentation comes from melanocytes, which are in the bottom layer of your skin, the stratum basale.

Lemon juice doesn't get absorbed anywhere near that deeply.

It will take around 2-3 weeks for results to show :).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
