Almost all beauty seekers know that the use of supportive macromolecular hyaluronic acid can fill in the hollows of the face and make the face more plump. But have you ever wondered how different types of hyaluronic acid work after entering the skin and ultimately "support" your beauty?
First of all, it is important to understand the structure of ** to understand the role of filler injections. **It is divided into three levels: epidermis, dermis and subcutaneous tissue.
The epidermis is the outermost layer, and its main function is to establish an external barrier against physical and chemical damage from the outside world. The dermis is mainly composed of fibroblasts, fibers, and stroma, but also contains structures such as blood vessels, lymphatic vessels, and nerves. The dermis provides immunity, and elastic fibers play an important role in the elasticity of **. The subcutaneous tissue is the main storage area of fat, which connects the muscles and is not only rich in blood vessels.
According to different needs, hyaluronic acid injections can play a role in wrinkle removal, shaping and moisturizing.
Hyaluronic acid is injected into the hollow parts of the dermis in the form of filler to achieve the effect of wrinkle removal, stimulate collagen proliferation, solve the problem of aging, and have more moisturizing effect, and the skin looks younger.
Through injection, hyaluronic acid can directly increase the volume of subcutaneous tissue, thereby playing a lifting effect, stimulating collagen proliferation, locking moisture in the skin, and injecting it into the areas that need to be improved to achieve the effect of shaping.
Hyaluronic acid is moisturizing, and its hyaluronic molecules are able to carry a large amount of water to replenish moisture to the skin, thus restoring youthful and supple skin.
When choosing fillers, it is necessary to choose fillers with different molecular weights according to the different injection sites. The common hyaluronic acid for injection on the market can be basically divided into three molecular weights: large, medium and small, and the hyaluronic acid with different molecular weights is different in terms of metabolic time, target site, specific effect and effect. When choosing hyaluronic acid, you should start with the molecular weight according to the advice of a professional doctor, because different molecular weights are suitable for different use needs.
Dr. Wang Yanhui pointed out that according to different beauty needs, the larger the molecule, the more suitable it is to be injected into the deep layer, and the small molecule hyaluronic acid is injected into the dermis to moisturize and rejuvenate the skin. Medium molecule hyaluronic acid is injected into the deep dermis to remove wrinkles and fill depressions; Large molecule hyaluronic acid is injected into deeper tissues and can be used for rhinoplasty, etc. Skin boosters, on the other hand, use small molecule hyaluronic acid.
Generally speaking, fillers with high molecular weight have better results, last longer, and are suitable for injection into deeper tissues, such as rhinoplasty. The small molecular weight of hyaluronic acid is more suitable for filling fine wrinkles and lip augmentation, etc., and is suitable for injection into the dermis, its absorption time is faster, and the maintenance time is relatively short.
In general, hyaluronic acid with large molecular weight has a better shaping effect, longer maintenance time, and deeper injection level, which is suitable for rhinoplasty and other items; Hyaluronic acid with small molecular weight is more suitable for filling fine wrinkles, lip augmentation, etc., **Superficial injection, fast absorption time, relatively short maintenance time.
