Your skin consists of thousands of tiny pores which contain sebaceous glands. These glands provide skin-softening sebum to the skin. When these glands produce sebum in excess or become infected with bacteria, the pores can become clogged, according to Medical News Today. The result is a red, often painful pimple. You can reduce the redness and swelling of a pimple by treating the underlying causes of inflammation. Treating inflammation also can help reduce the likelihood the pimple will develop into an acne scar.

Apply a dab of toothpaste onto the pimple and leave it on overnight, according to AcneTeam.com. This at-home method can reduce swelling and redness. Note that only the paste form of toothpaste is effective in combating this condition -- gel-based toothpaste will not have the same effect.
Wash your face with a mild cleanser to remove the toothpaste and take off any oils that may have accumulated overnight. This helps to keep further bacteria from being introduced to your pimple. Gently towel dry your face and avoid disturbing the pimple.
Apply an icepack to the affected area, recommends AcneTeam.com. Always wrap the ice in a protective towel or cloth in order to prevent the area from burning with the ice. Leave on the affected area for 10 minutes. This will constrict the blood vessels that make the area appear red.
Crush an aspirin until it becomes a fine powder -- you also can use aspirin powder, which is sold in a pouch. Mix the powder with two to four drops of tap water. Apply this paste to your pimple and leave it on for five minutes. Rinse carefully with warm water. The aspirin will help to reduce inflammation and swelling, making your pimple appear less noticeable. Repeat at night to continue reducing the redness.
Apply a spot treatment cream containing active pimple-fighting ingredients, such as benzoyl peroxide, salicylic acid or sulfur. Apply the cream to both the pimple itself and the area surrounding it. This helps to kill bacteria inside the pimple and prevent future breakouts to the area, according to AcneTeam.com.
