Follicular Hyperkeratosis (FHK) is caused by keratin buildup around the hair follicles, which creates bumps on the skin. These bumps usually form around friction sites on the skin (the waist, hips, knees, and elbows.) These symptoms are more common in children and usually lessen in the adolescent and adult years.
It is recommended for children with follicular hyperkeratosis to wear loose clothing to ease friction.
K6a patient: “In winter, I put lotion or Vaseline on her body. Urea and Lachydrin burn and do not work. Some perfumed body lotions burn also. I usually use suave or generic brands without perfumes. Tight jeans or corduroy irritate the bumps. She usually wears knit pants (cotton).”
??? patient: “I have bumps on the elbows, knees, and buttocks. I put Vaseline on the elbows and wrap a bandage around them for a few days until they are soft and enough to ‘twing right off.’ On the knees, use a good moisturizer as often as possible. On the buttocks, use moisturizer as often as possible — usually before bed — to let it breathe without anything on it besides the moisturizer. There are no more bumps on knees and elbows now, but you should still moisturize them to prevent any bumps from coming back. It helps the buttocks too. It can take a while for progress, but they will go away if you keep working at it.”
K17 patient: “I use creamy petroleum jelly on the arms and legs.”
