Why NOT to use toothpaste on pimples?

It is seen that people put a small quantity of toothpaste on their pimples and get pleased when the a little liquid flush out that red spots but is it safe to use or not?

The post was old but its very informative. There were so many posts on social media in Thai language that says that it is not safe to use toothpaste because it causes irritation.

The statement is confirmed by America’s Cleveland Clinic and British Association of Dermatologists which said that the paste has certain ingredients and chemical like alcohol and baking soda which could dry pimple out but they are not meant to put on face directly.

Similarly, the association said that people should use acne treatment creams because the paste can discolor the skin; although,it has anti-bacterial and anti-inflammatory properties.
