Heard of the eye drop hack for pimples? According to dermatologists, eye drops can calm angry zits by reducing redness. This is because the active ingredients in anti-redness eyedrops are vasoconstrictors, meaning they constrict blood vessels. When applied to your skin, those vasoconstrictors can help decrease redness and swelling. However, it’s important to note that this hack is a temporary fix and does not treat your acne on the long-term. To clear your breakout, you’ll want to use proper spot treatment methods.
