Is keratosis pilaris curable?

No "cure": It is not a condition can be cured but can be under control. Dry skin and genetic link are the main causes of this condition. Dry skin can be an inherited condition, and weather (like, winter), living environment (like, in dry desert regions) and personal habit of skin care (like, never use moisturizers) all aggravate it. You can't change that.

No: Keratosis pilaris (kp) is an extremely common skin disorder. It usually runs in families and can be associated with eczema. It usually does not require treatment unless it becomes a cosmetic concern. Treatments never cure only minimize the condition. Best thing to do is see a dermatologist for evaluation and to discuss potential treatments options.
