A friend did facial collagen introduction and went to a beauty salon to do it with an instrument. Did it work? What are the disadvantages? Please specify.

Collagen introduction into the face is generally effective and the effect is better. The introduction of collagen can supplement the nutrients needed by the skin in time, stimulate the growth of collagen, make the skin look smoother and more delicate, and achieve the effect of rejuvenation. But we must choose regular medical institutions and professional doctors to operate, so as to avoid adverse side effects. Pay attention to skin care in daily life, try to choose skin care products suitable for your skin, and eat more foods rich in collagen in your diet. As long as you go to a regular beauty salon or a regular hospital to introduce collagen into your face, it is basically safe, but if you go to some small beauty salons, the safety factor is not high. Usually you can eat more foods with high collagen content, such as pigskin and trotters, which are very good choices. In addition, pay attention to the maintenance of the face.
