No, toothpaste is not an effective or safe treatment for pimples. While it may temporarily dry out a spot due to ingredients like baking soda or menthol, it also contains irritants like SLS and fluoride that can damage your skin barrier, cause redness, burning, and even chemical burns. Dermatologist-approved treatments like benzoyl peroxide or salicylic acid work far better and safely.
Why Do People Think Toothpaste Works on Pimples?
Toothpaste became a popular home remedy because some formulas contain baking soda, hydrogen peroxide, or triclosan — ingredients that can dry out surface oil and shrink a pimple’s appearance overnight. This drying effect is often mistaken for “healing,” when in reality it’s just dehydrating the skin around the blemish, not treating the underlying cause of acne.
It’s a similar story with other kitchen-cabinet “fixes” — like using Dettol on pimples, which people also assume disinfects and dries out a spot safely, but can be just as damaging to the skin barrier.

What Happens When You Apply Toothpaste on a Pimple?
Toothpaste applied to skin can cause:
- Irritation and redness from sodium lauryl sulfate (SLS), a foaming agent not meant for prolonged skin contact
- Burning or stinging, especially on sensitive or already-inflamed skin
- Dryness and flaking that can make skin produce more oil to compensate, worsening acne
- Hyperpigmentation or scarring in some cases, particularly on medium to deep skin tones
- Chemical burns with prolonged or repeated use, especially with whitening toothpaste containing peroxide
Is Toothpaste Safe for All Skin Types?
No. Toothpaste is riskiest for sensitive, dry, or acne-prone skin, where the barrier is already compromised. People with oily or resilient skin may see fewer visible side effects, but no skin type benefits from toothpaste being used as intended acne treatment — it wasn’t formulated for this purpose.
What Should You Use Instead of Toothpaste for Pimples?
Dermatologist-recommended alternatives that target acne without damaging your skin barrier include:
- Benzoyl peroxide (2.5–5%) — kills acne-causing bacteria and reduces inflammation
- Salicylic acid — exfoliates inside the pore to clear blockages
- Spot treatments with sulfur — dries out pimples gently without harsh irritants
- Ice wrapped in cloth — reduces swelling and redness short-term
- Retinoids — prevent future breakouts by regulating skin cell turnover (prescription-strength options available at Athena Skin Clinic)
When Should You See a Dermatologist for Acne?
If you’re relying on home remedies like toothpaste because over-the-counter products aren’t working, it’s a sign your acne needs professional evaluation. See a dermatologist if you experience:
- Painful, cystic, or nodular acne
- Breakouts that leave dark spots or scars
- Acne that hasn’t improved after 2–3 months of consistent OTC treatment
- Sudden or severe flare-ups
At Athena Skin Clinic, we offer customized acne treatment plans — including chemical peels, prescription topicals, and in-clinic procedures — designed for your specific skin type and acne severity.
Frequently Asked Questions
Does toothpaste get rid of pimples overnight?
Toothpaste may reduce the appearance of a pimple by drying out its surface, but it doesn’t treat the bacteria or inflammation causing it, and results are temporary at best while risking skin irritation.
Can toothpaste cause scarring?
Yes. Toothpaste can cause irritation, burns, and hyperpigmentation, particularly with repeated use or on sensitive skin, which can lead to lasting marks or scars.
Which toothpaste ingredient is most harmful to skin?
Sodium lauryl sulfate (SLS) and hydrogen peroxide (common in whitening toothpaste) are the most likely to cause irritation, dryness, and chemical burns on facial skin.
What is a safe home remedy for pimples?
Ice application, gentle cleansing, and over-the-counter benzoyl peroxide or salicylic acid spot treatments are safer and more effective than toothpaste.
Should I see a dermatologist for occasional pimples?
Occasional pimples usually don’t require a dermatologist, but persistent, painful, or scarring acne should be evaluated for a proper treatment plan.
