If you’ve ever Googled a quick fix for a pimple, you’ve probably come across the idea of using toothpaste for acne. It’s one of the most persistent skincare myths out there—and one I hear about often in clinic and online.
As a board-certified dermatologist, I get why this “hack” is tempting. Toothpaste feels minty, drying, and powerful. But just because something dries out a pimple doesn’t mean it’s helping your skin heal.
Let’s break down why toothpaste for acne isn’t recommended—and what actually works instead.
Why People Use Toothpaste for Acne
The idea behind toothpaste for acne is that it will “dry out” a pimple overnight. Many toothpastes contain ingredients like menthol, baking soda, hydrogen peroxide, or alcohol, which can feel cooling or tightening on the skin.
I’ll be honest—I tried this myself as a teenager. And it didn’t end well.
While toothpaste may temporarily reduce oil or moisture on the surface, that doesn’t mean it’s treating acne at its root.
Why Toothpaste Can Make Acne Worse
Toothpaste Is Not Made for Facial Skin
Toothpaste is formulated for teeth—not for the delicate skin barrier on your face. Many formulas are highly alkaline and can disrupt your skin’s natural pH, leading to irritation, redness, and peeling.
Irritation Can Trigger More Breakouts
When the skin becomes inflamed or irritated, it can actually worsen acne and increase the risk of post-inflammatory hyperpigmentation, especially in deeper skin tones.
In some cases, toothpaste can cause what looks like a chemical burn.
What to Use Instead of Toothpaste for Acne
If you’re dealing with pimples, there are safer, evidence-based options that dermatologists actually recommend.
Benzoyl Peroxide for Acne
Benzoyl peroxide helps reduce acne-causing bacteria on the skin and is especially helpful for inflamed pimples. It’s available in different strengths and formulations designed specifically for facial skin.
Salicylic Acid for Acne
Salicylic acid works by gently exfoliating inside the pore, helping to unclog blackheads, whiteheads, and early pimples. Unlike toothpaste, it’s formulated to be used on skin safely.
These ingredients are studied, regulated, and designed for acne—not teeth.
When Acne Needs More Than a DIY Fix
If you’re finding that pimples keep coming back, won’t heal, or leave marks behind, it may be time to move beyond home remedies. Acne is a medical condition, and there are many treatment options depending on the type of acne and your skin type.
Seeing a dermatologist can help you avoid trial-and-error approaches that may do more harm than good.
