Lips are not only key to our appearance but also serve as a way to express emotions. How can we keep our lips hydrated and tender? Let’s explore some important care techniques together.
First, we need to understand the structure of lip skin. The skin on the lips is thinner and more delicate than that on other parts of the face, as there is no thick stratum corneum on the surface of the lips and not enough sebaceous glands. This structure makes lips more susceptible to moisture loss, leading to dryness and cracking. Many people believe that lips have no sebaceous glands at all, but in reality, there are a small number of sebaceous glands on the lips that secrete oils, which can form a protective barrier to some extent and reduce moisture evaporation.
In daily life, the use of lipstick or certain lip products often leads to dryness, such as medications containing oral retinoids, which can decrease sebaceous gland function and further dry out the lips. Additionally, unrestrained exfoliation is not a good idea, as the skin on the lips is very thin, and excessive exfoliation can worsen the condition of the lips.
There are many causes of lip cracking. First, environmental factors such as dry air or frequently licking the lips can contribute. Second, improper use of skincare products, such as those containing irritants like fragrances or beeswax, may trigger allergic reactions, causing discomfort to the lips. It is especially important to pay extra attention if there is inflammation or an allergic condition and to avoid using harsh, irritating products.
So, how should we care for our lips? First, while it is not necessary to constantly apply lip balm, it is very important to choose the right one when your lips feel dry. There are some recommended lip products in the market, such as those containing petroleum jelly, which are reasonably priced and highly effective.
After a full facial care routine, remember to apply lip balm again before bed, as this can provide better hydration for the lips. Especially if you are using skincare products like retinoid cream or retinol lip balm, which may cause dryness, extra care for your lips is needed in those cases.
