Drying Out Oily Skin and Acne
Toothpaste is known for its ability to dry out oily areas and pimples. Many DIY acne remedies suggest dabbing toothpaste on pimples to reduce swelling and redness overnight. When applied to the arms, toothpaste could similarly dry out the skin and address issues like clogged pores or small breakouts. The silica and baking soda in toothpaste help absorb excess oil, leaving the skin drier by the next morning.
Mild Exfoliation and Skin Brightening
Certain ingredients in toothpaste, such as baking soda and hydrated silica, act as gentle abrasives. When applied to the skin, they can help exfoliate the outer layer, removing dead skin cells and making the skin look brighter. While applying toothpaste overnight may not give the same results as a dedicated exfoliation product, it can lead to a slight improvement in skin texture and brightness. The next day, you might notice that your arms feel smoother and appear more radiant.
Reduction in Minor Inflammation
Toothpaste can have a mild anti-inflammatory effect due to ingredients like triclosan and essential oils. If you are experiencing mild inflammation, such as from minor burns, insect bites, or skin irritations, leaving toothpaste on your skin overnight may help reduce the inflammation and redness by the next day. The cooling sensation also contributes to this effect, offering temporary relief.
Potential Whitening Effect on Dark Spots
Some people claim that the whitening properties of toothpaste, especially those with baking soda or hydrogen peroxide, can help reduce the appearance of dark spots or discoloration over time. While there is limited scientific evidence to back up this specific claim, anecdotal reports suggest that leaving toothpaste on areas with pigmentation may have a mild lightening effect, especially if done regularly. After one night, however, results would be minimal, though there could be a slight improvement in the tone of your skin.
The Risks of Applying Toothpaste Overnight
While there may be some benefits, there are also potential risks and downsides to this unusual hack.
