1. Uniformity: When using a cotton pad to apply lotion, due to the fiber structure of the cotton pad, it can help the lotion cover every inch of the skin on the face more evenly, especially the small areas that are difficult to reach with hands such as the sides of the nose and corners of the mouth. When applying by hand, there may be uneven distribution of water in certain areas of the face due to limited hand contact area or uneven application force.
2. Absorption effect: The cotton pad can help remove dead skin cells on the surface of the skin during gentle wiping, promoting the penetration and absorption of subsequent skincare products. The slight friction of the cotton pad can also promote facial blood circulation, further enhancing the skin's absorption efficiency of water and milk. In contrast, although applying by hand can achieve a certain absorption effect, it may not be as efficient as using a cotton pad.
3. Hygiene: Using cotton pads can prevent direct contact between hands and the mouth of skincare bottles, reducing the risk of bacterial contamination. Especially when the hands are not clean enough or in a humid environment, using a cotton pad can more effectively protect the hygiene quality of skincare products. However, applying by hand may increase the possibility of skin care products being contaminated due to the presence of more bacteria on the hands.
