3. A collagen boost for the pout: Before doing any trick, you should remember to get rid of the dead skin cells from your lips. The plump effect will not come out well if there’s a layer of dead skin on your lips. So what you can do is make a DIY sugar lip scrub at home. Take some tablespoon of sugar and mix it with a teaspoon of olive oil. Gently use the mixture to scrub off the dead skin from the lips. Wash it off using cold water. Then wait for a second before putting on your favourite lipstick. The blood circulation in your lips will go up which will automatically boost up the collagen. How easy is that? Isn’t it?
