Herbal concoctions are the best acne treatment. They are safe and effective but unfortunately herbal ingredients are very hard to find and sometimes very expensive if you are living in a city. So, some people who get zits look for other methods to get rid of it like astringents or creams.
I really don’t know if herbal-based astringents and creams are already developed because I they are the best compared to chemical-based ones. I think it would be also safe and friendly to one’s liver!
