The skin on your lips is specially designed: it lacks the protective layers and oil glands that provide natural protection on other parts of your body. This makes your lips more susceptible to dryness, irritation, and environmental damage. Regular hydration is essential to keep your lips healthy and soft, and to prevent chapping, inflammation, and other unpleasant symptoms.
The physiological background of hydration
The lips have a mucous membrane-type skin that relies heavily on external hydration.
Since they lack sebaceous glands, the lips are unable to lubricate or moisturize themselves , so they are completely dependent on external care.
Therefore, ingredients such as:
- hyaluronic acid – attracts and retains water
- glycerin – a humectant that helps bind moisture
- shea butter – softening, regenerating and protective component
Together, these ensure that the moisture content of the lips is maintained in the long term.
According to a study in The Journal of Clinical and Aesthetic Dermatology, regular use of moisturizing products significantly improves skin barrier function and reduces transepidermal water loss (TEWL) (Draelos, 2018).
This is especially important for the lips, where a lack of hydration quickly leads to discomfort and damage.
How and how often should we hydrate?
Dermatologists recommend applying lip care products several times a day , especially:
- after eating or drinking
- in cold, windy or extreme weather conditions
- after sunbathing or UV exposure
Evening hydration is especially important because during the night, the skin enters a more intensive regeneration phase. The right lip balm can work smoothly at this time, helping to replenish moisture more deeply.
Summary
Regular hydration is the foundation of healthy lips. Scientific evidence shows that consistently used lip balms:
- prevent dryness and cracking
- reduce irritation
- strengthen the skin's natural protective layer
- provide long-term comfort and softness
Lip care is a simple yet crucial step in maintaining skin health — especially when you choose quality, targeted moisturizing ingredients.
