I had a mole on my neck removed by a stich biopsy approx 6 weeks ago. It was cut out, and I received three stitches. 6 weeks later, the redness is still there. It is small in size, but still noticable. Should the redness be gone by now? If not, when? And is there a cream such as aloe vera that I can apply to help accelerate the process? Thanks.
