I really like facial peels for blotchy skin and red marks. It's much easier, cheaper and affordable than getting laser treatments done. The peel I used, from skin culture (do it at home), worked wonders for me because the peel is deep and effective, although somewhat expensive..it was totally worth it. There's other cheaper ones out there that seem good. If you're not into peels than maybe a good exfoliator would help. I know that juice from a lemon tones and evens out the skin over time. Not sure about anything else as I just stick to high quality peels. Then for maintenance just use a light peel like every month or two to keep your skin perfectly evened.
