Detailed answer

Hair keratosis pilaris, also known as follicular keratosis, is a common skin condition characterized by small, rough bumps on the skin's surface. It is primarily caused by the buildup of keratin, a protein that protects the skin. Allergies to skincare products, on the other hand, occur when the immune system reacts to certain ingredients in the products. While skincare product allergies can cause skin irritation, redness, or rash, they do not directly cause hair keratosis pilaris. The exact cause of this condition is not fully understood, but it is believed to be influenced by genetic factors, dry skin, and hormonal imbalances. Treatment options for hair keratosis pilaris focus on exfoliation and moisturization to improve the appearance of the bumps and manage symptoms.
