A: Using vacuum negative pressure to suck out acne, suck away dirt on the skin surface and some aged cuticles, and then add some water to wash it. It seems that a "deep cleaning" has been completed, but the symptoms are not cured. At that time, it seemed like a new nose, but the sebaceous glands under the skin still produced new acne according to the original daily rhythm. Repeated high-frequency use of small bubbles can also lead to excessive cuticle destruction and skin barrier damage. In short, bubbles are good, but don't drink too much.
A: Photonic rejuvenation is a kind of laser cosmetic treatment. It uses broad-spectrum light with a certain wavelength, which can be adjusted according to the hand tools or filters of different devices. Therefore, when whitening effect is needed, the wavelength can be selected for melanin, and when removing red effect is needed, the wavelength can be selected for red blood. In the field of medical beauty, photon rejuvenation is known as the panacea of "medical beauty".
It is worth noting that for a period of time after photon rejuvenation, you should pay special attention to sun protection and don't stay in the sun. At the same time, after a period of photon rejuvenation, the skin will feel dry, so it is necessary to do a good job of hydrating and moisturizing.
A: The biggest difference is that fruit acid is water-soluble and salicylic acid is fat-soluble. Salicylic acid can better penetrate into pores, regulate alienated keratinocytes in hair follicles, and make skin with large pores such as acne, closed mouth and red pox discharge oil, and then gradually restore healthy pores.
In the field of high concentration, the difference between them is that high concentration of fruit acid can act on the dermis and promote collagen regeneration, thus achieving the anti-aging effect. It can peel off the melanin existing in the superficial layer of skin and has the effect of removing superficial spots. High concentration salicylic acid is an effective method to treat moderate and severe acne in addition to first-line acne drugs in hospitals.
A: This question is quite sensitive. There are many reasons for the formation of the rich bag. If the doctor determines that it is a muscle problem, he can inject some botulinum toxin to relieve it. The principle is the same as that of stovepipe needle, but it depends on the doctor's advice.
