Minimizing the appearance and relieving the discomfort of cold sores is possible overnight - and even in shorter periods of time, according to information provided by the Huffington Post. Though sores are unlikely to vanish overnight altogether, a number of remedies can prevent sores from being noticed by those those closest to you, explains board-certified Manhattan and New Jersey dermatologist Dr. Rebecca Baxt.

A last-minute appointment with a physician for a cortisone injection offers the quickest fix. The associated inflammation shrinks instantly as the diluted cortisone is injected directly into the sore, states Dr. Baxt

Valtrex, Acyclovir and other antiviral prescriptions help the body to control inflammation, while fighting infection and keeping sores from spreading.

Over-the-counter remedies are also proven to be effective; Abreva has a stellar reputation for alleviating pain and reducing the size of cold sores quickly, while allowing for the application of makeup on the top of sores. The popular eye drop Visine is a trusted home remedy that works wonders to take the red out of cold sores.

Applying a cold compress or tea bags directly to the sore for at least 20 minutes is also known to reduce redness and swelling. Tylenol or ibuprofen may be used in conjunction for pain relief, advises Dr. Baxt.
