What makes lip care different from skin care?

Unlike ordinary skin, lip tissue is mucous membrane. The outer layer of the lip (or stratum corneum) is extremely thin or even completely absent in most people. As a result, moisture evaporates from the lips much faster than from ordinary skin causing lips to dry out easily. This dryness frequently results in chapping and cracking, and increases the risk of inflammation, infection and burning sensations.

See our "What are Lips?" section for more information on the composition of lips.

How do I protect my lips from the sun?

Lips have little or no melanin, the natural skin pigment that screens out the sun's harmful ultraviolet rays. Sun damage can alter collagen (which gives lips body and resilience) and can even lead to melanoma. Lips should be protected from the sun with a product that contains a Sun Protection Factor (SPF) of 15 or more. It is also important to remember that the sun's harmful rays are always present whether it's July or January, sunny or cloudy.

Do lips need to be protected indoors?

It's a good idea to work lip protection into your daily skin care regimen whether you spend time outdoors or not. Outdoor factors such as sun, wind and cold can speed up the rate of lip moisture loss. What you may not realize is that lips frequently suffer indoors from a lack of moisture in centrally heated or air-conditioned rooms in which the relative humidity is low. Dryness is also the enemy when a winter cold or flu strikes. Lip irritation can even be caused by certain types of food, cosmetics and cigarette smoke.

While protection is great, how do I heal already chapped lips?

If your lips get chapped, time is of the essence. The sooner you attend to them the faster they will heal. For both seriously dry lips, and even for treatment of cold sores, Blistex recommends using a product like Blistex Lip Relief Cream, that brings a cooling relief to lips and moisturizing ingredients to rehydrate them.

What causes cold sores?

Cold sores and fever blisters tend to develop when an individual has a cold or fever, but they also can be triggered by sun exposure, emotional distress, intestinal illness and menstruation. Eliminating all of the sources that can contribute to the onset of cold sores and fever blisters is impossible, but sufferers can condition their lips with products such as Blistex Daily Lip Conditioner and Blistex Lip Relief Cream to reduce the sun's impact and limit cracking that can lead to making lips more vulnerable.

Is it possible to reduce the effects of overexposure and aging on the lips?

Using a lip care product with a sunscreen and effective moisturizers can help reduce the effects of two of the main contributors to an aged appearance; sun damage and moisture loss. The majority of Blistex products provide proven moisturizers with sun protection ranging from SPF 10 to SPF 30.

Should lip balm be worn under or over lipstick?

Lip balm or ointment works best when worn under lipstick, which allows protective ingredients to be in direct contact with the lips. Using a moisturizing lip care product before lipstick application will help color go on more evenly.
