How to get rid of a deep pimple 
Clean your face twice a day. 
To keep oil and dirt away, you will need to commit to a cleansing routine where you clean your face twice a day. Use a plant based oil cleanser or a commercial cleanser than is non-comedogenic, meaning it will not clog your pores.

For large pores, one good way to clean them is to apply a non-comedogenic moisturizer.; b). Do not use products that contain alcohol, as they can irritate and dry out your skin. When applying the cleanser, use your fingertips and be gentle.; c). No matter the intensity of your cleansing routine, it should be clean. Avoid harsh or sensitive cleansers like makeup because they can easily make breakouts worse.; d). Mix your cleanser with warm water in your usual part of the house. Let it sit for a minute, which will open up your pores and strengthen them.;
