The cleaning effect of the face brush comes from mechanical friction. The bristles are very fine and can touch the dermatoglyphs and hair follicles that cannot be touched by the hand. This is true whether it is reciprocating vibration or circular rotation. The reciprocating vibration has a smaller range of motion, so the friction force is smaller than that of the circumferential type, so the exfoliating force is relatively weak.
The powerful cleansing power of the face wash brush can indeed bring a series of effects, such as smoother skin, finer skin, reduced acne, more complex skin tone, increased skin absorption, etc. This makes sense because the skin Cleaner and thinner cuticles can be smoother and more delicate.
Acne caused by poor keratin metabolism, and abnormal thickening of keratin due to aging and sunlight, with such a powerful cleaning and exfoliating tool, you can get better skin performance. At the same time, the barrier function is weakened, especially the thinning of the stratum corneum and the increase in skin permeability, so it is more likely to be penetrated by external substances, but this more penetration is a double-edged sword, meaning that the skin is also more susceptible to irritation Harmful substances and irritants are also more likely to penetrate, and bacteria are more likely to invade.
How to use face wash brush correctly
1. For aging skin with thick cuticles, true acne skin, skin that is prone to oil in the T zone and no barrier damage, you can use a face wash brush.
Through exfoliation and cleansing, skin can be smoother and more delicate. It also improves the whiteheads in the T area. The blackhead removal function of the face wash brush is weak, because there are many hairs in the blackheads. In the deep skin, the brush cannot be brushed out. Considering the renewal cycle of the skin, it is not necessary to use it too frequently, it is enough to use it once or twice a week.
2. For sensitive skin, inflammatory skin, dry skin, face wash is not recommended.
This type of skin barrier is damaged, lacking sebum membranes, thin stratum corneum, and lack of lipid between stratum corneum cells. What is needed is protection, not strong cleaning. This powerful cleaning and exfoliating function will exacerbate barrier damage, dilate capillaries, and even cause skin irritation, redness, and damage. Oily skin with large pores, but in fact, seborrheic dermatitis, using a cleansing brush will never make the pores smaller, but it will make the inflammation worse (this type of skin is often called external oil and internal dryness).
3. Normal skin, normal skin, available or not, better.
It is not recommended to exfoliate deliberately, not only face wash brushes, cotton pads, tear-off masks, wipes, fruit acids, etc., are not recommended. If you feel that you do n’t buy a face-washing brush and your life is not high-end, then it ’s okay to buy one. Occasionally, do n’t let it hurt your skin.
4. Pay attention to how to use it.
The friction between the brush and the skin is also affected by the pressure. The tighter the brush head is pressed against the skin, the greater the frictional force and the stronger the exfoliating force, so please do not press too much.
5. Cleansing, especially heavy makeup, cleansing tools are a good helper.
It does help clean, but sunscreen, light makeup, no need to use a brush, because it hurts the skin, you should minimize the makeup.
All in all, the face wash brush is not an artifact, it is just a brush, a product of the combination of technology and marketing. After understanding the principles, precautions, and applicable conditions, it is up to everyone to decide whether to use the face wash brush or not.
