Toothpaste mostly irritates pimples and can make them worse rather than actually treating acne.

Quick Scoop: What Does Toothpaste Do to Pimples?

  • It can dry out the very top layer of skin a bit, so the pimple may look slightly smaller or “flatter” for a short time.
  • It does not unclog pores, kill acne bacteria effectively, or prevent new pimples, so it’s not a real acne treatment.
  • Common toothpaste ingredients (baking soda, menthol, hydrogen peroxide, whitening agents, strong flavoring, detergents) are designed for teeth, not facial skin, and often cause irritation.
  • That irritation can damage the skin barrier, trigger more redness, and sometimes lead to more breakouts or even mild burns and discoloration.
  • Dermatologists generally say to skip toothpaste and use proven spot-treatments instead.

“Toothpaste will likely do more harm than good for your skin… you end up with a redder, more irritated pimple than you started with.”

Why People Think It Works

  • Old toothpaste formulas sometimes included triclosan, an antibacterial that could modestly reduce acne bacteria, which helped start the myth.
  • Even then, triclosan was weaker than proper acne treatments, and concerns about resistance and safety mean it’s not recommended for acne.
  • The “tight, dry” feeling after toothpaste makes people think it’s shrinking the pimple, but it’s mostly surface dehydration and irritation, not true healing.

Mini example: You dab toothpaste on a whitehead at night, wake up and it looks a little flatter but the surrounding skin is red, stingy, and flaky—that’s irritation, not a cure.

What Toothpaste Can Actually Do to a Pimple

  1. Short-term effects
    • Slightly dries the surface, sometimes making the bump look smaller for a few hours.
 * Can sting or burn on application, especially on sensitive or broken skin.
  1. Likely side effects
    • Redness, burning, and peeling around the spot.
 * Increased oil production afterward as your skin tries to compensate, which can clog pores.

 * Risk of more inflamed pimples or small chemical burns with repeated use.
  1. Longer-term risks if used often
    • Irritated, sensitized skin that reacts more easily to other products.
 * Dark marks or discoloration after irritated pimples heal (especially on medium to deep skin tones).

What To Use Instead (Dermatologist-Backed)

If you’re tempted to use toothpaste because it’s cheap and handy, these options are safer and actually target acne:

  • Salicylic acid : Unclogs pores and gently exfoliates; good for blackheads and small inflamed pimples.
  • Benzoyl peroxide : Kills acne-causing bacteria and helps with red, inflamed spots.
  • Retinoids (like adapalene) : Help prevent clogged pores and improve overall acne over time.
  • Azelaic acid : Helps with both breakouts and dark marks.
  • Hydrocolloid pimple patches : Absorb fluid from whiteheads and protect the area from picking, without harsh irritation.

Simple “in-a-pinch” routine for one angry pimple (not medical advice, just general info):

  1. Gently cleanse skin with a mild face wash, not harsh scrubs.
  1. Apply a tiny amount of a proper spot treatment (e.g., benzoyl peroxide or salicylic acid) just on the pimple.
  1. At night, you can add a pimple patch over a whitehead instead of toothpaste.

If you have frequent or painful acne, seeing a dermatologist is the safest way to get a real plan.

Forum & “Latest News” Vibe Around This Hack

  • On social media and forums in 2025–2026, “toothpaste on pimples” still pops up as a nostalgic DIY hack, but most skin experts online now clearly call it outdated.
  • Recent health and skincare articles from major clinics and brands emphasize that modern acne products are widely available and much safer than toothpaste.
  • Many creators now do “myths I stopped believing” style posts where toothpaste-on-zits is one of the first things they say they regret trying, especially after experiencing burns or worse breakouts.

Mini Story

You’ve got a big event tomorrow, a bright red pimple tonight, and you remember that old “just use toothpaste” trick your friend swore by in high school. You dab it on, go to sleep hoping for magic, and wake up with a slightly flatter bump—but now the skin around it is painfully red, flaky, and refuses to sit under makeup. By the evening, the area looks angrier than before. The next time this happens, instead of reaching for toothpaste, you try a proper spot treatment and a pimple patch; the pimple still isn’t gone instantly, but it calms down without burning your skin.

Bottom Line

To answer “what does toothpaste do to pimples?”: it may dry the surface a little, but mostly it irritates skin and can worsen acne, so it’s better avoided in favor of real acne treatments.
