Many toothpaste formulas—especially traditional white pastes—contain active agents like baking soda, hydrogen peroxide, alcohol, menthol, and even triclosan. These ingredients are known for their drying, antibacterial, or anti-inflammatory properties, which can theoretically help reduce oil buildup, calm redness, and shrink the size of a breakout. While this method isn’t a substitute for proper skincare, it raises a common question: which toothpastes may help shrink pimples without irritating your skin? In this article, we explore that question in detail and highlight both the best and worst options for this popular DIY acne hack.
Toothpastes That May Help Shrink Pimples 🪥🦷
If you’re going to try it, go for the basic white paste (not gel) and avoid anything with strong whitening or flavoring agents. Here are a few that people have found useful:
1. Colgate Cavity Protection Toothpaste
- Why it helps: Contains baking soda and hydrogen peroxide, which may dry out pimples. It’s simple, no-frills, and less likely to irritate.
- Best for: Oily or combination skin.
2. Arm & Hammer Advance White Toothpaste
- Why it helps: Loaded with baking soda, which absorbs oil and gently exfoliates.
- Caution: Can be drying, so don’t leave it on overnight. 10–20 minutes max.
3. Crest Tartar Protection Paste
- Why it might help: Some varieties contain zinc citrate, known for antibacterial benefits.
4. Colgate Baking Soda and Peroxide Whitening Toothpaste
- Why it might help: Combines baking soda and peroxide—both commonly used in DIY acne remedies.
5. Sensodyne Extra Whitening (Paste, Not Gel)
- Why it might help: Gentle and non-gel, with mild abrasives that may dry out pimples.
How to Use Toothpaste to Shrink Pimples (Safely) 💡
- Wash your face and pat dry.
- Dot a small amount of toothpaste onto the pimple—not the whole area.
- Leave on for 10–20 minutes, or until it starts to flake.
- Rinse off gently with lukewarm water.
- Moisturize, especially if your skin feels tight or dry.
Avoid leaving it on overnight—it can cause redness, peeling, or even mild burns.
Toothpastes to Avoid for Acne Use 🚫
While some toothpastes can dry out a pimple in a pinch, others are more likely to cause irritation, redness, or even chemical burns. Avoid the following types of toothpaste when attempting this hack:
Whitening Toothpastes with Harsh Bleaching Agents
- These often contain hydrogen peroxide at higher concentrations or abrasive whiteners that can damage skin.
- Examples to avoid: Colgate Optic White, Crest 3D White Luxe, Sensodyne Whitening Repair.
Gel-Based Toothpastes
- These usually lack the drying or antibacterial ingredients found in white pastes and often include dyes or alcohol-based ingredients that can irritate.
- Examples to avoid: Any clear or colored gels, especially those with strong flavors.
Charcoal Toothpastes
- Although trendy, they tend to be too abrasive for skin and have no proven benefit for acne.
- Examples to avoid: Hello Activated Charcoal, Crest Charcoal, Colgate Total Charcoal.
Toothpastes with Strong Flavors or Artificial Dyes
- Flavored options (like cinnamon, bubblegum, or citrus) often contain allergens and artificial coloring that can inflame or irritate skin.
- Examples to avoid: Kids’ toothpastes, flavored gel toothpastes.
Bottom Line
Toothpaste might help shrink a pimple fast, but it’s not a magic bullet. If you’re desperate and careful, a dab of basic, non-whitening toothpaste can work in a pinch. But for the long game? Stick to actual skincare products. Your face will thank you.
