I can't honestly say this little tip started with Pinterest. It's been a quick fix go-to forever! But putting toothpaste on a breakout is doing nothing but irritating the surrounding skin! Toothpaste will dry out your skin while not doing much for the actual blemish. The worst part? Toothpaste can be caustic on skin if it's not rinsed off so leaving it on as a spot treatment over night can actually lead to chemical burns and dark spots due to skin damage.
Need a spot treatment alternative? Skin Script Blemish Spot Treatment | $17 | is perfect! Best part? It can work through your makeup so you can apply throughout the day to get that blemish gone, fast!
