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.
