Murad post acne spot lightening gel
I got a delux sample from sephora 2 months ago and I used it is few times but didn't really get into it. Now I'm concerned about my acne scars and wanted to lighten them but the product has turned a slight yellow color. I can't remember if it was that slight yellow color to begin with or not and every picture shows it has clear gel. Has my bottle spoiled in 2 months? Sould I throw it out and or still use it? Thanks very much for any help.
