How do I fix lip discoloration. Part of my lips are pink from cold sores.?

Don't get Cold Sores. Your lip and tissue changes color when the healing process begins. Look at a cut or scrape on your skin. Much more pink when the healing process begins. There is a cascade of healing processes going on during the first 48 hours. The key is knowing when a cold sore is about to begin, prodermal stage. Get with your dentist or doctor to prescribe an anti-viral in this time period.
