Ways Your Skin Reveals Underlying Health Issues

Cracked Lips

Visibly dry and cracked lips can be caused by more than the weather or constant lip-licking. Cracked lips can occur due to an allergic reaction to lip products and makeup, and can also be a symptom of inadequate dietary niacin or zinc intake, which is most commonly found in vegan and vegetarian diets. High concentrations of niacin and zinc are found in animal products such as chicken, fish, or liver, hence why those who follow a plant-based diet may be lacking these nutrients. Another common cause is perleche, a fungal infection associated with a vitamin deficiency or chronic illness, and can have specific symptoms such as redness, scaling, or fissuring around the lip region.
