3.DON’T: Apply Toothpaste
Save the toothpaste for your teeth. Although some ingredients in toothpaste might help dry out pimples, toothpaste can trigger acne. To make matters worse, the fluoride and whitening ingredients could cause an allergic reaction when applied to the skin.
4.DO: Try Corticosteroid Injections
For large acne cysts, corticosteroid injections may offer a quick fix. A dermatologist injects a diluted version of a corticosteroid directly into the pimple to reduce swelling and prevent scarring. After the injection, the cyst will shrink over the next few days. You should not attempt to pick at or treat a cyst yourself.
