You must have dabbed toothpaste on a pimple, hoping that it would shrink. Pimples develop when skin oil, called sebum, mixes with dead skin cells and form a pore

Using Toothpaste as cheap and quick fix is actually not effective for reducing acne.
Putting toothpaste on a pimple can dry out the skin, cause irritation, even get bacteria on your face. New York City dermatologist Dr Douglas Altchek said .

Acne is more common during teenage years because more sebum forms as hormone levels increase.



‘Everybody wants a gimmick or a quick fix that’s not expensive, which is why we turn to home remedies like toothpaste hoping it will help,’ Dr Altchek

Toothpaste has been utilize for years as a way to treat pimples. Supposedly, it contains hydrogen peroxide and baking soda, two ingredients which ‘dry out’ pimples.
But the concentrations that occur in toothpaste are too harsh for the face, which can result in skin drying out or becoming irritated, Dr Altchek said.
