1. Acne Scars
I have some pretty wide crater-ish acne scars and some red depressions that looks like there’s still some blood beneath. All the skin above is already pretty much healed.
(I have a somewhat oily skin, My face has not much acne already, maybe just one or two occasionally. )
I would like to know how do I get rid of these acne scars, are products like Hiruscar useful?

2. Pigments
I have pretty much brown pigments on my nose and some on my face, some pigments are dark (maybe it is a mole instead, but it is beneath the skin rather than above). How do I get rid of these pigments or ‘moles?’ ?

Thank you!
