First, it’s important to note that pimples take time to heal, so it’s highly unlikely that your acne would go away overnight. However, there are steps you can take to reduce swelling and in turn, make blemishes less noticeable. The American Academy of Dermatology recommends:
• Gently washing the skin and patting it dry with a clean towel.
• Wrapping ice cubes in a cloth and applying them to the pimple for 5–10 minutes.
• Applying a spot treatment that contains at least 2% benzoyl peroxide.
