The occurrence of seborrhea does not require treatment if there are no symptoms. Seborrhea is an ectopic sebaceous granule caused by localized abnormalities in the metabolism of skin or mucosal glands, and is associated with localized endocrine disorders. Most of them occur on the mucous membrane of the lips or both cheeks of the mouth and appear as white or yellow granular papules distributed in clusters. There are no obvious ulcers or signs of destruction on the surface, and sometimes a frosting-like sensation occurs when the granularity is strong. If irritation is present, a small local excision or laser removal is required. If the symptoms are obvious, you can gargle locally with compound chlorhexidine gargle and do not eat spicy and irritating things.
