Healthy, soft, and plump lips are obtained by maintaining and increasing the moisture content. The best way to ensure your lips are well hydrated is to ensure high intake of water on a daily basis (minimum of 8 glasses or 64 ounces).
Avoid the urge to lick your lips when they are dry as saliva acts only as a temporary moisturizing solution but eventually causes more harm as it causes dryness.
Products, which include ingredients such as cocoa butter or Shea butter and vitamin E, are good sources of moisture.
Exfoliating is very important in getting better results as dead cells are removed and the skin is clean and ready for moisturizing. You get lip-exfoliating , which also have moisturizing compositions.
Exfoliation can also be done naturally by using a soft toothbrush (different from the one you use for your teeth) to gently, scrub your lips in circular movements. Another method is by first moistening your lips and then applying sugar or salt using your finger and moving lightly in small rotations. A word of caution is not to use salt if you have cuts or wounds.
There are many cosmetics such as lip balms , chap sticks or lip creams that are available to help you get soft lips. Here too it is important you apply these products by either using your finger, or gently dabbing in circular motions to get a good outcome.
Margarine (butter) and honey (only pure honey) are good products for moisturizing too. Take a small amount of butter or honey and apply it gently with your finger in tiny rotations. Leave it on for one or two minutes and wipe it clean with a soft towel or tissue. You could repeat this if required.
Butter gives your lips that sheen and lush texture while honey adds to the plumpness of your lips. You can also use coconut juice, rose milk, olive oil, or baby oil in a similar fashion to get radiant and healthy lips.
At night, before you sleep apply two layers of crème or petroleum jelly such as Vaseline. Gently massage a layer in rotating motions and then apply a thicker layer on top. The second layer will be absorbed during the night and will help increase moisture content.
It is important to note that products over a year old, cheap products or sharing of products may pass on bacteria to your lips, which may be harmful.
