We invented all kinds of cleansing tools, from loofah to sponges, cotton pads, and wet wipes. Nowadays, we start to use facial cleansing brushes.

　　And sponges, cotton pads, wipes, scrubs, etc., due to their physical friction properties, the exfoliating power is strong, and when combined with cleansers, it will achieve high cleansing power and high exfoliating power.

　　Humans have a tradition of using brushes to enhance the cleaning effect, including shoe brushes, brooms, toothbrushes, and so on.

　　The cleansing effect of the facial Pore Cleaner Facial Brush comes from mechanical friction. The bristles are very fine and can touch the skin patterns and hair follicle openings that cannot be touched by the hands. This is true whether it is reciprocating vibration or circular rotation. The reciprocating vibration has a smaller range of movement of the bristles, so the friction force is smaller than that of the circular type, so the exfoliating force is relatively weaker (a little milder).

　　The brush head is divided into the sponge and fine hair. Because the thicker the hair, the stronger the friction, so different diameters and shapes of hair have been developed to suit different needs. However, this is only a decrease in strength, and the principle remains the same. Using a sponge brush head, in addition to friction, also increases the adsorption force (capillary action).

　　Cleaner skin, thinner stratum corneum, can be smoother and more delicate, acne caused by poor keratin metabolism (note: it is acne, not inflammatory acne or sensitive rash, cosmetic acne), and because of aging, Sunlight causes an abnormal thickening of the keratin. With such a powerful cleansing and exfoliating tool (including but not limited to wash brush, cotton pad, and tear-off mask), better skin performance can be obtained. The barrier function is weakened, especially , the skin permeability increases, and it is easier to be penetrated by foreign substances (please note: this more penetration is a double-edged sword, which means that the skin is also more susceptible to irritation, Harmful substances and irritants are also easier to infiltrate, and bacteria are also more likely to invade).

　　At the same time, because of its very strong cleaning function, it is especially worthy to be wary of excessive cleaning caused by improper use.
