We’ve all been there—a big pimple shows up at the worst possible time, and you’re desperate for a quick fix. Enter one of the most persistent skincare myths: applying toothpaste on pimples to dry them out overnight.
It’s a widely shared DIY “hack,” but as a board-certified dermatologist, I’m here to set the record straight. Let’s explore what really happens when you apply toothpaste to your skin—and whether it’s doing more harm than good.
Why People Use Toothpaste for Pimples
The idea likely comes from the fact that many toothpastes contain drying agents, like:
- Baking soda (sodium bicarbonate)
- Hydrogen peroxide
- Alcohol
- Triclosan (in older formulas)
- Menthol and fluoride
These ingredients can temporarily reduce the size of a pimple by drying it out. But that doesn't mean it’s safe or effective.

What Actually Happens When You Put Toothpaste on a Pimple
At first glance, toothpaste may seem to help by reducing oil and drying the blemish. However, the long-term effects can be damaging:
❌ Skin Irritation
Toothpaste is made for your teeth—not your skin. Applying it topically can cause burning, stinging, or peeling, especially on sensitive or acne-prone skin.
❌ Increased Redness and Inflammation
Instead of calming the pimple, ingredients like fluoride and menthol can trigger contact dermatitis—a type of skin irritation that may make the blemish look worse.
❌ Damage to Your Skin Barrier
Toothpaste can strip the skin of its natural moisture and disrupt your protective barrier, making you more prone to breakouts and sensitivity over time.
Dermatologist’s Verdict: Don’t Do It
Toothpaste is not formulated to treat acne. It doesn’t target the root causes of breakouts—like bacteria, excess sebum, or clogged pores—and can worsen inflammation or cause scarring.
If you need to shrink a pimple fast, there are safer and more effective alternatives.
What to Use Instead of Toothpaste for Pimples
✅ Benzoyl Peroxide (2.5–10%)
Kills acne-causing bacteria and reduces inflammation. Try PanOxyl or Neutrogena On-the-Spot.
✅ Salicylic Acid (0.5–2%)
Penetrates pores and helps unclog them. Look for CeraVe SA Cleanser or The Ordinary Salicylic Acid 2% Solution.
✅ Sulfur-Based Spot Treatments
Helps dry out blemishes with less irritation. Try Mario Badescu Drying Lotion or Kate Somerville EradiKate.
✅ Hydrocolloid Pimple Patches
Protects the pimple, reduces inflammation, and draws out pus overnight. COSRX Acne Pimple Master Patch is a fan favorite.
✅ Ice Therapy
Applying an ice cube wrapped in a clean cloth for 5–10 minutes can reduce swelling and redness.

When to See a Dermatologist
If you experience:
- Frequent or cystic breakouts
- Scarring or post-acne marks
- Acne that doesn’t respond to OTC treatments
…it’s time to consult a dermatologist for prescription solutions like tretinoin, topical antibiotics, hormonal therapy, or oral medication.
Final Thoughts: Skip the Toothpaste
While the idea of using toothpaste on pimples is tempting for its convenience, it’s ultimately more harmful than helpful. Stick with products specifically formulated for acne—and give your skin the gentle, consistent care it deserves.
Your skin will thank you.
