Can the skin condition keratosis pilaris be caused or worsened by hygiene or diet? (dermatology)

Possibly: Kp can appear more exaggerated in dry, pale skin. Facial kp can be more exaggerated with spicy food, or other foods that can cause flushing (ie wine, cheese, sour).

Yes, diet.: Keratosis pilaris may be genetic and can triggered by vitamin deficiencies, food sensitivities, and allergies. Certain vitamins like vitamin a and d can be helpful in treating kp. Cetain dietary changes, such as gluten-free, dairy-free and sugar-free might be useful in the treatment as well. Testing vitamin levels and reactions to food would be useful for coming up with a plan of action.

No: Kp is a common, benign, autosomal dominant genetic condition that affects about 40% of the population. There is no credible data that diet affects kp at all. There are anecdotal reports that vitamin a supplementation helps, but no evidence that vitamin a levels are low in patients with kp. Any relationship to gluten is conjecture at best.

KP is an inherited: skin disorder. It is due to plugging of follicles so using topicals that exfoliate will help a lot, (scrubs, lactic acid, urea) foods typically do not affect it
