It all depends on the patient
Nonetheless, a patient's tolerance towards the disease is different. Some experience more serious reactions than others with the same gluten intake. Those who are hyper-sensitive to gluten should stay away from cosmetics and skin products with gluten. Even with a small amount, it can cause them both harm and pain if ingested. Others, on the other hand, have no serious problems with any cosmetic that have even just a small trace of gluten.
