I do not take vitamins and minerals. I think, however, that I should take iron to improve the state of my nails (also I am on copper coil which can lead to anemia). I do not eat red meat. I do eat turkey and fish but that it. I would not say that my skin is bad but I do get spots and sebacious white/black heads. I also have dark cirles under my eyes which I need to cover with the make up. My parents did not teach me to drink up two litres of water a day and it is a struggle for me. However, I do not feel dehedrated. So, I wonder, whether a good skin is down to a good balanced diet plus vitamins and minerals or it is down to genes.
