From past few months I have developed dark circles and my skin has become very dull (lacks lusture). I am a professional and now working from home from last two years. I take home made meals at regular intervals, exercise 3-5 days a week, sleep 6-8 hours a day. Screen time is around 8 hours (includes laptop, phone & tv). I drink 3-4 litres of water in a day. Recently I have noticed my lips have started turning dark (specifically the border areas). I don't smoke at all. No matter whatever I try (home remedies) my skin somehow doesn't look fresh. Currently I am taking calcium and iron tablets from last 3 months as my haemoglobin was 9.5 and I was severely deficient of vitamin D. Thanks Seema
