The skin of the lips differs significantly from the rest of the body's skin and is therefore particularly sensitive. This sensitivity is due to a combination of anatomical and functional features. The lips lie in a transition zone between the facial skin and the oral mucosa, known as the vermilion. This area has an exceptionally thin stratum corneum, which allows blood vessels to show through easily and gives the lips their characteristic red colour.
Unlike other skin areas, the lip skin has neither sebaceous nor sweat glands. As a result, it cannot form a natural protective film of sebum and dead skin cells that elsewhere serves as a barrier against environmental influences. This lack of a protective layer makes the lips particularly vulnerable to external factors such as cold, heat or dry air. In addition, the cells of the lip's stratum corneum keratinise very little, which limits their ability to act as a natural seal against drying out.
Another peculiarity of lip skin is the absence of pigments like melanin. While these pigments provide some protection against UV rays on other parts of the skin, the lips are exposed to this stress without protection. This makes them particularly light-sensitive and increases the risk of sun damage.
The causes of dry lips are varied and can be due to both external and internal factors. A major cause is lack of moisture, resulting from insufficient fluid intake or increased fluid loss, e.g. through sweating. Also, frequent moistening of the lips with saliva worsens the problem, as evaporation dries the skin out further.
External factors such as cold winter air, dry indoor heating air and intense sun exposure also contribute to drying. In summer, lips lack the pigment cells that could protect them from UV rays. Also, salty sea water can draw moisture away.
Conditions such as colds or infections, e.g. with herpes viruses or fungi, can also lead to dry or cracked lips. A deficiency in vitamins or minerals, especially iron, zinc or vitamins B and E, can impair skin regeneration and make it brittle. Stress can also play a role, as it reduces saliva production and therefore does not sufficiently moisten the lips.
Finally, incorrect lip care can also lead to dry lips. Lipsticks or care products with fragrances and colourants dry out the delicate skin. Instead, products with replenishing ingredients such as shea or cocoa butter should be used.
The signs of dry lips can appear in various ways and to varying degrees. The first symptom is often a dry, rough or flaky feeling to the touch. In many cases, visible cracks or splits form on the lip surface, which can be sensitive or painful.
With dryness, the lip skin often tends to scale or peel, which exacerbates the problem. Redness commonly occurs, indicating inflammation or irritation. A feeling of tightness is also often reported, which can restrict lip movement and cause discomfort. In severe cases the lips can bleed, which increases the distress.
Yes, dry lips can be effectively treated with hyaluronic acid. This substance not only makes the lips soft and supple again, but also supports the healing process for cracks and dryness. Hyaluronic acid can also be used preventively to avoid dryness and improve the skin structure of the lips.
Using finely cross-linked hyaluronic acid targets and replenishes the lips' moisture depot without unnaturally increasing volume. This method is particularly suitable for people who want soft and well-cared-for lips without aiming for a noticeable change in volume. The result is smooth, youthful-looking lips with natural suppleness.
Hyaluronic acid can bind many times its own weight in water. As a result, small wrinkles are smoothed, skin elasticity is improved and the lips appear fuller. Hyaluronic acid is available not only as injections but also in specialised lip care products such as balms or lipsticks. These products often combine hyaluronic acid with nourishing ingredients like castor oil, which additionally protects the lips and gives them shine.
Yes, creamy and fatty lip care products can help protect the lips from external influences and keep them supple. Especially nourishing are products with rich ingredients such as shea butter, beeswax, honey or healing plant extracts from chamomile and calendula. They provide moisture and protect the delicate lip skin from drying out.
Products with natural oils such as olive oil, jojoba oil or castor oil are particularly recommended because they do not contain harmful mineral oils. Products that contain paraffin oil (a by-product of petroleum refining) can, on the other hand, make the lips even drier: they initially coat the skin but do not keep it permanently moist. Mineral oils can also be harmful to health and are suspected of being genotoxic or carcinogenic.
For winter, especially at freezing temperatures, fatty products with as little water as possible are ideal, as they form a long-lasting protective film. In summer, however, a lip balm with UV protection (at least SPF 20) is important to protect the lips from harmful sun exposure and prevent drying out.
Coconut oil is an excellent remedy for dry lips, as it deeply moisturises the skin. Thanks to its hydrating properties, it helps to soothe and soften dry, cracked lips. It is often called an emollient because it binds moisture in the skin and protects it from drying out. Coconut oil works best after a bath or shower, when the skin is particularly receptive, but can be used at any other time of day.
Another advantage of coconut oil is its antiseptic and antibacterial action. These properties help protect the lips from germs and prevent cracked skin from becoming further infected. In addition, coconut oil has anti-inflammatory properties that can reduce swelling and soothe the skin.
Coconut oil not only provides moisture to the lips but also gives them shine and supports their natural lip colour. Being made from natural ingredients, it is a safe alternative to many commercial lip balms that often contain chemical additives. With regular use it helps prevent dry, rough lips and keeps them healthy and supple.
Dry lips are often uncomfortable, but with the right care they are easy to manage. Regular moisture supply, protection from cold and wind and sufficient fluid intake help keep lips soft and supple.
