Looks like he got boxcar,some rolling and no doubt he'll have ice pick also.soneach needs a different treatment type,not hard but takes time.

you intend to do at home?

Quad gave good advice...

The pics are blurry, from what I see he has hyperpigmentation as the major issue. This is dealt with using IPL, v-beam, excel v laser, or 1064nm. Can't tell the ethnicity but Picosure is very good for Asian populations.

For pits, subcision

I can give you a plan PM me.
