When it comes to treating a pimple, cold therapy is generally recommended over heat. Applying a cold compress or ice pack can help reduce inflammation, soothe the skin, and minimize redness associated with a pimple. Cold therapy can also help shrink blood vessels around the pimple, which may reduce swelling. It’s important to avoid applying ice directly to the skin and instead wrap it in a cloth or use a cold compress.

However, if the pimple is deep-rooted or has come to a head, applying warmth in the form of a warm compress can help to open up the pore and facilitate drainage. This can be beneficial for pimples that are ready to be extracted. Warmth can also help increase blood flow to the area, promoting healing.

If you have persistent skin issues or if the pimple worsens, it’s advisable to consult a dermatologist for proper evaluation and treatment.
