Hi All,

I would like to know when grading acne scars, what lighting should we use? Is it harsh, normal or diffuse light?

When I use harsh spot lighting, some of my scars look very deep, like over 2mm in depth, but I know it shouldn't be the case since my derm has kept telling me those are shallow boxcar/rolling scars. When I see those scars out of house, they are less deep and looks like shallow scars and under diffuse light, they are barely visible.

Thus, I was wondering what light should we use in regards to scar grading.
