A recent study published online reveals that early ear piercing reduces the risk of keloids. The study http://www.onlinenews.com.pk/details.php?id=162745 says that delaying ear piecing until pre-teen or teen years can aggravate the chances of developing keloids.
Keloids are uncontrolled growth of fibrous tissue after an injury or scar on any area of the body. Keloids can occur on ears, scalp, top of the foot and even the chest, especially after first piercings. The findings of the study based on a survey of 27 females and 5 males showed that people who had their ears pierced at the age of 11 or older were more likely to develop keloids than those who took to ear piercing before that.
