According to the size of the molecule, hyaluronic acid can be divided into three categories: macromolecule, medium molecule and small molecule. Different molecular sizes of hyaluronic acid, the role is different, the filling effect is different, the maintenance time is different, and the parts used for filling are also different.
1, macromolecular hyaluronic acid: the texture is hard, mostly bidirectional crosslinked, because of its larger particles, in order to avoid uneven after filling, mainly filled in deep skin. It is generally used for decree lines, facial sculpture, nose augmentation, chin pad, etc., and is also often used for a wide range of fillings, such as cheek abundance, forehead abundance, apple muscle, etc.
Its metabolic rate in the body is slow, so the effect is maintained for a relatively long time, according to personal physique and brand differences, generally between 10-18 months.
2, medium molecular hyaluronic acid: slightly soft texture, suitable for soft tissue filling and deep wrinkles. It is usually used to remove wrinkles, and the filling part is usually the nasolabial groove, lips and wrinkles, and it is also used to fill the depression, such as the apple muscle, jaw and other parts.
The part filled by the middle molecule hyaluronic acid is also the middle to deep layer of dermal tissue, which can not be filled in the skin surface, and can generally be maintained for about one to one and a half years.
3, small molecules of hyaluronic acid: mostly one-way crosslinked, more gentle, the main function is to moisturize the skin, for human skin dermis fill, supplement the dermis missing water, and repair damaged skin.
Small molecule hyaluronic acid metabolism in the body is relatively fast, different brands are different, but the effect of maintenance time is generally about half a year
In simple terms, large molecules are suitable for filling and shaping, medium molecules are often used to fill and remove wrinkles, small molecules are superior in hydrating and moisturizing, we can consider when choosing according to their actual needs, of course, personal judgment can not be used as a criterion, if there is a real demand, or need to determine a suitable program through facial diagnosis.
