Keloid/infections: Keloids need not form at every scar. Tattooing is a form of self mutilation and is associated with many undesirable side effects, hypertrophic scars and keloids being two. It could also be that the sites with hypertrophic scars or keloids had low grade infection from tattooing. It would be prudent to refrain from further self mutilation. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.
