Cleansing brush effect principle
We already know that humans have a tradition of enhancing the cleaning effect with brushes, including shoe brushes, brooms, toothbrushes and the like.
Cleansing brush effect from the mechanical friction. Brush hair is very thin, you can touch the hand can not touch the dermatoglyphic, hair follicles mouth. Whether it is reciprocating vibration, or circular rotation, are the case. Reciprocating Shock Because the bristles' range of motion is small, the friction is smaller than the circumference, so the exfoliating force is relatively weaker (milder).
Brush head is divided into sponges, fine hair, because the thicker the stronger the friction of the hair, it also developed a different diameter and shape of hair, suitable for different needs. However, this is only a weakened intensity, and remains the same in principle. The use of sponge brush, in addition to friction, but also increased adsorption (capillary action).
Acoustic cleaning, I personally think that is a promotional language. It has been 300Hz (vibration frequency of 300 beats / second) of the vibration is said to be ultrasonic, in fact, ultrasonic waves must be above 20000Hz, 300Hz can only produce ordinary mechanical waves, I do not think this wave has the ability to clean, in essence, still Rely on the mechanical friction created by the contact interface of the bristles with the skin to achieve cleansing and exfoliation functions.
From a brand's experimental data, it can provide X times the cleaning power, and then bring a series of effects, such as smoother skin, more delicate skin, acne reduction, skin look more delicate, increase skin absorption capacity, etc. Is justified because:
Skin clearer, thinner cuticle, smoother and more delicate, acne due to poor keratinocyte metabolism (Note: acne, not inflammatory acne or sensitive rash, cosmetic acne), and because aging , Sunlight causes unusually thick keratosis. With such a powerful cleansing and exfoliating tools (including but not limited to face brush, cotton pad, tearing mask), better skin performance can be obtained. Impaired barrier function, especially the stratum corneum thinning, the skin permeability increases, it is more likely to be infiltrated by foreign matter (Note: This more infiltration is a double-edged sword, which means that the skin is also more susceptible to stimulation, Pests and irritants are also easier to penetrate and bacteria are more easily invaded.)
At the same time, but also because of its very strong cleaning function, but also especially worthy of guard against inappropriate use and cause over-cleaning.
