What if we told you there was a DIY blemish zapping lotion that not only shrinks the pesky thing, but also reduces the redness and can even kill bacteria? Well, it's true. You can actually make your own overnight treatment at home. All it takes is your favorite astringent or tea tree oil and a bottle of calamine lotion. It'll cost you less than $10 at the grocery store, and will last you around six months to boot.
