First of all, you might want to drink a lot of fluids during wintertime, so your skin can be hydrated at all times. Secondly, in order to protect your lips from cold dry air, arm up with the best lip balm formulas you can find.
In order for your lips to stay protected inside as well, you could purchase a humidifier and keep it running in the house, so that the air inside will remain at a certain humidity level and not get too dry. Sunscreen could also be applied to your lips, as this can protect them from the negative effects of sun exposure.
In addition, in order to look after your lips, you should try to stay away from wind as much as possible and never leave the house without balm protection on your lips. However, you should avoid menthol lip balms, as they will only dry out the skin on your lips even more.
Lipstick formulas that tend to be drying should also be avoided as much as possible during winter. Moreover, remember to apply some lip balm on your lips before going to bed, too. The balm will work its magic during the night and will soften your lips much more than in the daytime. Therefore, you will wake up with lips softer than ever.
Another thing that you can do in order to take care of your lips during winter is to exfoliate them as soon as you finish with washing your face. For this, you can use a simple washcloth or even a homemade lip scrub. Make your own natural lip scrub by mixing one tsp. of honey and tsp. of baking soda with a few drops of olive oil until a smooth paste is formed. Dab the mixture onto your lips and gently massage with your finger tips to remove dead skin cells. Wash it off with water and apply a drop of olive oil or your favorite lip balm.
After doing this for a few times, you will be able to see that your lips will soften. All in all, it is not difficult to take care of your lips in the winter time, as long as you just follow some simple ground rules.
