As we know, the outermost layer of the skin is the stratum corneum, which consists of 10-20 layers of dead cells without nuclei arranged closely together to form a barrier to the skin to prevent foreign matter from entering the skin and to prevent external stimuli from harming the skin's internal tissues. While the stratum corneum protects the skin, it also prevents skin care products from entering the skin.
But how can this film stop the almighty human beings? Thus, the microneedle was invented. Microneedles are composed of densely packed tiny needles. It is said that the thinnest needles have reached the micron level, only 0.08 mm. Microneedles can pierce rows of small holes in the stratum corneum, opening countless small channels to the closed skin, so that pharmaceutical ingredients or skin care products can easily pass through the stratum corneum and enter the skin to play a role. In the beginning, the microneedle was a device invented by the hospital to allow the medicine to reach the skin directly, and the beauty industry later learned from it.
Microneedles open numerous small channels on the surface of the skin, allowing skin care products that are difficult to penetrate the stratum corneum to easily enter the inside to play a role. At this time, if some repair, whitening, differentiation, and anti-aging ingredients are used in a targeted manner, these ingredients can directly reach the target location to play a role, and good whitening, anti-aging, and repair effects can be achieved. This is the completion of microneedles. Later, some consumers can feel the important reason for skin changes.
In addition, after the microneedle pierces the skin, it will cause tiny wounds on the skin. At this time, the internal tissues of the skin will receive a signal. Someone is destroying the skin tissues. The skin tissues must be repaired quickly, which will stimulate the skin's self-healing ability and promote Form new skin tissues, accelerate collagen proliferation, remove fine wrinkles, and slow down skin aging. It can also achieve the purpose of treating depressed scars, such as acne marks and acne pits.
However, microneedling therapy also has great limitations, and the improvement of micro-targeted skin is also limited, and not all skins can achieve satisfactory results. The final effect of micro-needle therapy is related to the professionalism of the doctor, the quality of auxiliary products, the patient's own skin characteristics, and the patient's later nursing habits.
