Why do lips get chapped? Why are my lips so dry when the temperature goes down? These are common questions we hear in the cooler months from autumn to winter. 

First off, chapped lips can happen any time of the year, but our lips can dry out when it's not properly hydrated and there is not much moisture or humidity in the air -- as is the case during autumn and winter (and while onboard an airplane).

Apparently, since our lips don't have oil glands like our skin, they become more susceptible to cracking or chapping. While cold, dry air can cause chapped lips, it can happen when you're exposed to the sun often as well.

Habits such as licking the lips further strip our lips of moisture, too. If you want to know how to stop chapped lips, then it's a good thing you're reading this piece!

At home, you can use a humidifier to retain optimum humidity indoors. When you're out and about, you may want to cover your mouth with a scarf to prevent cold weather from drying your lips. In drier months, avoid unnecessary sun exposure and wear a lip balm with minimum SPF 15.

Our favorite treatment for chapped lips is using lip balm. So, we rounded up the best lip balms to prevent chapped lips in colder months:

Vaseline Lip Therapy Rosy Lips is one of the best lip balms for severely chapped lips. On days when your lips are flaking, stinging or splitting, this heavy-duty, thick lip balm will help heal chapped lips fast.

The rosy shade also adds a pink tint on the lips!

On casual days when you want to skip your signature lipstick, put on this tinted lip balm instead. It adds color to your face so you can rock that no-makeup look.

It's also wearable at any age, which makes it a well-loved lip balm of many generations.

We like this lip balm with SPF because it doesn't have a bitter taste, like other lip balms with SPF tend to have. Moreover, it has a high SPF number.
