In Hong Kong, many people face the problem of dry skin, especially during the dry seasons, when this condition is even more common. Whether you have oily skin or dry skin, the correct moisturizing method is key to maintaining healthy skin. Today, let’s explore the causes of dry skin and how to effectively moisturize.
Firstly, the main causes of dry skin can be divided into two categories: inflammation and rapid turnover of the stratum corneum. When the skin is exposed to certain allergens, it can trigger inflammation, leading to dryness. Once inflammation occurs, continuing to use moisturizing products may actually worsen the allergic reaction; at this point, it is advisable to temporarily stop using all potential allergens. Additionally, the presence of chronic inflammation, especially under normal conditions of oil secretion, can also cause dry skin.
The second reason is the rapid turnover of the stratum corneum, which is often seen in conditions such as psoriasis or atopic dermatitis. These issues prevent the stratum corneum from retaining necessary moisture, resulting in rough and dry skin. Therefore, for these specific situations, we need to seek suitable moisturizing products to improve the condition.
Besides these fundamental causes, environmental factors also play a significant role in causing dry skin. The climate in Hong Kong is highly variable, especially in winter, when a drop in temperature and reduced humidity can affect the skin’s moisture retention capacity. In this case, choosing the right moisturizing products for oneself is crucial.
So how should we properly moisturize? The key to moisturizing is to select products that can strengthen the skin’s natural barrier. Among these, natural moisturizing factors (NMF) and cement-like substances between skin cells are essential for maintaining skin moisture. These ingredients can absorb moisture from the environment and prevent it from escaping. It is important to note that while using external products can improve hydration, the truly effective approach is to stimulate the skin to naturally produce these moisturizing factors, such as using skincare products containing retinoids and retinol to enhance the skin’s own moisturizing capabilities.
Additionally, many people have misconceptions about moisturizing, believing that more moisturizing products are better; in reality, this practice may be counterproductive. Overusing moisturizing products can burden the skin and lead to an imbalance in oil secretion. Therefore, choosing appropriate products and usage based on one’s skin type is the correct way to care for the skin.
