Water emulsion is actually the most basic skincare product and a basic standard in the skincare process. Its main function is to provide our skin with basic hydration and moisturization, so that our skin will not worsen fine lines and wrinkles due to dryness and dehydration. Especially with age, the skin's hydration and repair ability will deteriorate, so water emulsion can choose corresponding effects to improve according to the skin's needs.

Similarly, the ingredients of water emulsion are different, and the targeted effects are also different, including basic moisturizing, oil control, anti-aging, anti-yellowing and whitening, and so on.

However, it is not entirely right to choose water emulsion based solely on its efficacy. We also need to consider its texture and suitable season to find the one that suits us.

This also explains why in summer, our skin, like us, likes to be refreshing and not sticky, especially oily skin. The relatively moisturizing lotion is like a special effect that increases the greasiness of our face by 10086 times, making it difficult for the skin to absorb and greatly reducing the subsequent makeup. In summer, most of the ingredients in water emulsion are moisturizing, such as the addition of moisturizers or extracts from plants or fruits, which make the skin feel clear and moisturized.

However, due to the dry weather in autumn and winter, the skin has a high demand for moisturizing and nourishing. In summer, most water emulsions are mainly refreshing, but it is difficult to meet the skin's needs. Therefore, autumn and winter water emulsions have been switched from refreshing to moisturizing. But for large oil fields, it is not absolute, and the specific decision still depends on one's own skin needs.

In fact, water emulsion does not necessarily need to be used together. Some matching water emulsions are mostly from the same series, and the ingredients are specifically designed for a certain effect and combination. For example, it is best to use a combination of milk first and water later. On the contrary, you also have a clear understanding of your skin type, and can be paired separately while ensuring that the ingredients of the lotion do not compete.

This is the same as whether face cream can replace eye cream. Both lotion and face cream play a moisturizing role. There is no very big difference in essence, but the strength of sealing is different from the degree of absorption of the skin. You can choose according to your own needs.

The lotion has less sealing ingredients, thinner texture and better absorption, and its moisturizing effect is relatively weak, which is suitable for the season when the air is not so dry. If you are a dry skin, it is enough to have a moisturizing and moisturizing face cream for facial care, but it is not recommended to use oily skin or face cream with high grease.
