There are itchy, rough, red and dark patches on my legs and upper part of the arms developed all of a sudden in a week or two. I am applying coconut oil after 2-3 days on them. Now the roughness and redness has gone. There are also se visible dark spots like acne (keel). Any natural foods or remedy to purify blood and better skin. I have bad habit of eating fast food on a daily basis which I am trying to control and reduce. Please advice, what foods or natural remedies that I can do at home and in daily routine to improve and purify blood and brings the healthy and glowing skin back. (could using hot water during bath has any relation with itchiness and redness. Cause it all started after the winter arrived.) please help!
