The skin on our lips is unique compared to the skin on the rest of our body. Lips are made up of thin, delicate skin that lacks hair follicles and sweat glands, making them more susceptible to dryness and chapping. In this blog post, we will explore the different characteristics of the skin on our lips, its function, and how we can take care of it.
Characteristics of lip skin
The skin on our lips is thin and delicate, with an average thickness of only three to five cell layers, compared to the 16 cell layers of facial skin. This thin skin lacks sebaceous glands, which produce oil to keep the skin moisturized. Additionally, the lips do not have sweat glands, which would help to regulate temperature and keep the skin hydrated. Therefore, lips are more susceptible to dryness and cracking.
Function of lip skin
Lip skin has several essential functions. Firstly, it provides a barrier between the outside environment and the sensitive tissue underneath. Secondly, it contains nerve endings that allow us to feel sensations such as touch, temperature, and pain. Thirdly, the skin on our lips contains melanin, which provides some protection against the harmful effects of ultraviolet (UV) radiation from the sun.
Taking care of lip skin
Taking care of the skin on our lips is essential to maintain their health and prevent dryness and cracking. Here are some tips for lip care:
- Use lip balm: Lip balm is a must-have for keeping lips moisturised. Look for lip balms that contain emollients like shea butter which helps to hydrate and protect the skin.
-
Stay hydrated: Drinking plenty of water helps to keep the skin on our lips and the rest of our body hydrated. Aim to drink at least eight glasses of water a day.
-
Protect your lips from the sun: UV radiation from the sun can cause damage to the skin on our lips. Use a lip balm with SPF protection, wear a hat or use an umbrella when outside in the sun.
-
Avoid licking your lips: Although it may be tempting, licking your lips can actually make them drier. Saliva evaporates quickly, leaving the lips drier than before.
-
Don't pick at dry skin: If you notice flaky or dry skin on your lips, resist the urge to pick at it. This can lead to bleeding and potentially an infection.
