My skin is generally pretty ok, although a bit oily but every month or so I get a nasty spot, always on my chin. Years of this has meant I have quite a few obvious purple/red scars on my chin. They aren't indented like acne scars IYSWIM but I am v pale & prone to redness so it is quite obvious. I usually wear SPF, tinted moisturiser & concealer but I'd like to stop & just wear SPF. The only thing that stops me is the scars. Is there anything I can do to reduce the redness? I am useless at this kind of thing!
