Many people do use clove oil products to treat acne and pimples. But keep in mind that clove oil is very strong and so it is probably best to research and purchase a product that has good customer reviews.
You want to be sure that you are not allergic to clove oil and hence it is a good idea to test a small amount of the product on your arm, near your elbow is a good spot. Then wait 24 hours to see if there is any reaction in this region. If no allergic reaction occurs then you can gently apply the product to the areas of acne, being sure to carefully follow the manufacturer’s instructions.
It is possible to try to make an acne remedy at home using clove oil and other ingredients, but since your skin, especially on your face, is quite delicate and sensitive, it is advisable to stick with already proven and safe products by reputable health product manufacturers.
