The viral DIY combination of toothpaste and Vaseline is frequently shared online as a quick fix for everything from clearing acne and removing blackheads to exfoliating lips or smoothing skin.
While mixing these two household products creates a distinct texture, dermatologists and skincare experts strongly caution against using this mixture on your skin—especially your face or lips.
Here is what you need to know about why this viral hack can be problematic, along with the reality behind what these ingredients actually do:
Why You Should Avoid Using Toothpaste and Vaseline on Your Skin
-
Severe Irritation from Toothpaste:
-
Toothpaste is formulated for hard tooth enamel, not delicate facial skin. It typically contains harsh ingredients like sodium lauryl sulfate (SLS), baking soda, alcohol, hydrogen peroxide, and essential oils (like mint).
-
Applying these ingredients to your skin can strip away your natural moisture barrier, causing chemical irritation, redness, contact dermatitis, burning, and peeling.
-
-
The “Occlusive Trap” of Vaseline:
-
Vaseline is pure petroleum jelly. It is an occlusive, meaning it creates a powerful, waterproof seal over the skin to lock moisture in.
-
If you mix toothpaste into Vaseline and apply it to acne-prone skin, the petroleum jelly traps the irritating toothpaste ingredients and skin bacteria underneath the seal, which can actually worsen breakouts, clog pores, and trigger painful inflammatory cysts.
-
-
Lip Irritation:
-
While some internet hacks suggest this mix as a lip scrub, the mint and menthol in toothpaste can cause micro-fissures and severe drying or chapping on the delicate skin of the lips.
-
What These Products Are Actually Made For (And Safe Uses)
-
Vaseline (Petroleum Jelly): Excellent for sealing in moisture on dry heels, elbows, chapped lips (on its own), or protecting minor cuts and scrapes from dirt and air.
-
Toothpaste: Formulated specifically to clean teeth, remove plaque, and freshen breath.
If you are looking for effective ways to treat acne, exfoliate dead skin, or deeply moisturize, it is always safest to stick to dermatologist-tested skincare products formulated specifically for those purposes rather than DIY chemical mixtures.
