I did my lollipop breast reduction & lift on 8th June, 2016. I'm 1 month post op & scars look black. Is this normal? (Photo)

I did my surgery in another state. It's not easy to be at close touch with my PS. I need professional advice. 1) are my wounds healing at normal rate because they look black. 2) can I start using silicone sheet? 3) Can I bare it like that (no sheet no steril strips) from now on ? 3) can I apply normal skin lotion on the wound area to make sure it's hydrated? Thanks
