You cannot prevent the growth of skin tags no matter how hard you try. Skin tags are a naturally occurring skin condition that appears on children and adults. We have treated children as young as nine years old with phenomenal results. There are some actions you can take to reduce the chances of skin tags appearing. These actions include avoiding friction in skin fold areas (like between your thighs, arm pits etc) and managing serious medical conditions like diabetes. The more you can prevent skin friction the less likely are the chances of skin tags growing.
