Wind and sun, haze pollution, and incorrect sitting posture will accelerate aging, the neck is the most fragile part of the human skin, plus the dermis of the neck is not as thick as the skin of the face, collagen fibers, elastic fibers are less, it is easy to generate fine lines due to external factors or behavior. The neck lines will instantly age you by more than ten years. The causes of neck lines 1, UV influence: sun exposure, computer radiation, etc. are the culprits. 2, natural skin relaxation, aging: skin collagen loss and synthetic ability to decline caused by skin relaxation, aging. 3, repeated head-up and head-down movements: head-up and head-down and other habitual movements are always inadvertently repeated countless times, the epidermis of the neck is easy to squeeze and produce traces, over time, the neck with a thin skin layer has wrinkles. 4, neck dry water: compared with facial skin, the neck tissue structure is weaker, less oil secretion, it is difficult to maintain moisture, it is more likely to produce wrinkles. Neck wrinkle grading standard 1.Grade 0: fine and smooth skin. 2.Grade 1: No visible wrinkles, only continuous skin lines. 3.Grade 2-Mild: shallow folds, but visible; a slight indentation; fine skin folds. 4.Grade 3-Moderate: relatively deep folds with clear neck creases; creases are visible in general, but disappear when stretched. 5.Grade 4-Severe: very long and deep folds with significant creases. 6.Grade 5-Very severe: very deep and long folds with drooping folds. Due to the special nature of the neck skin makes its part extremely difficult to maintain, I believe you have tried many means to save it 1.Cosmetics Only act on the surface of the skin, it is difficult to absorb. 2.Phototherapy There are limitations to improve deeper wrinkles 3.Filler injection Cross-linked translucent filler may produce nodules All of the above means are not the most perfect solution.

Hi Body is the first product approved by CFDA for neckline treatment. Hi Body uses the principle of dermal cell activation therapy to achieve the effect of smoothing necklines! Are the ingredients of Hi-Body safe? Hi Body is a Class III medical device product approved by CFDA for dermal injections, researched and developed by Amicor Technology Development Co. The main ingredients are amino acids, peptides and vitamins, and the basic ingredient is hyaluronic acid, all of which are necessary for the synthesis of collagen in skin tissues, and the metabolic mechanism is clear. Can Hi Body be used for a long time? Yes. Hi-Body can supply cell nutrition and promote cell renewal. By systematically improving collagen production in the dermis, Hi-Body improves the efficiency of collagen fiber mesh reconstruction, which improves skin quality and restores the elasticity and smoothness of the dermis, resulting in silky smooth and elastic skin. When do the results of Hi-Body appear? How long does it last? After Hi-Body injection, neck lines are supported and smoothed, and the treatment effect is visible 24h after injection; Hi-Body treatment is carried out in a course of treatment, and the maintenance time after a single course of treatment is 6-12 months (the maintenance time varies according to individual differences). In order to maintain the good treatment effect, it is recommended to have a neckline tightening treatment every 3 months after a course of treatment, which can effectively prolong the beauty time. How to achieve a more natural injection effect? When treating neckline, treatment should be carried out according to the treatment course, and there will be a certain degree of improvement after each treatment. The degree of improvement is related to the degree of skin laxity and the depth of neckline, while the more lax skin can be appropriately reduced in the single dosage and increased in the frequency of treatment when filling neckline. If the unevenness of the skin persists after injection, the appropriate amount of hyaluronidase can be used to dissolve and adjust.
