The skin on our lips is extremely delicate and particularly vulnerable to dryness and discomfort. In fact, the superficial layers of lip skin are five times thinner than the rest of the face. ¹ Unlike facial skin, lips do not produce sebum, so they lack a protective hydrolipidic film² and are more prone to irritation.
Lips are also constantly exposed to environmental stressors such as cold, wind, and humidity³. Frequent licking of the lips may feel soothing, but saliva actually dries out the skin even more, contributing to chapping and discomfort.
A consistent lip care routine helps to hydrate, nourish, and protect this fragile area, preventing dryness, cracking, and premature signs of ageing. Using a specialised lip balm or treatment ensures your lips remain soft, smooth and comfortable throughout the day.
