The microneedle can be maintained for about 1-3 years after three times, and the specific maintenance time depends on personal physique and nursing situation. After doing microneedle surgery, it usually takes a long time to maintain skin care. Micro-needles stimulate the skin mainly by rolling, which can produce a large number of microtubules, allow active ingredients to penetrate into the skin cell layer, regenerate the skin from the inside out, stimulate collagen regeneration at the same time, help the fiber tissue rearrange, and facilitate local repair. Generally, proper nursing lasts for a long time, about 1-3 years. If you want to use microneedles for treatment, you should pay attention to choosing a professional plastic beauty skin care center and pay attention to skin care at ordinary times.
