Fillers: types, benefits, and harms - SamanthaBeequeen/Fillers-types-benefits-and-harms GitHub Wiki

Fillers are products (from the English word "fill" - to fill), which are inserted under the skin by injection in order to correct the volume of the lips, the shape of the nose, cheeks, cheekbones, and get rid of deep wrinkles. Several decades ago, dermal fillers based on hyaluronic acid appeared in aesthetic medicine, and the beauty situation has changed radically. The natural beauty and naturalness of the skin, which is achieved by an absolutely safe and affordable contouring procedure, is in fashion again. Injections with a hyaluronic base allow to smooth out depressions of varying severity, fill in the missing volume of soft tissues, optimize biochemical processes inside the dermis and create an ideal hydro balance for moisturizing and radiant skin of the face and body literally in a matter of minutes. Fillers based on hyaluronic acid are made from non-animal products, which is excellent for allergy sufferers with a reaction to chicken protein and other components. As a rule, it is a polymer synthesized from bacteriological strains of streptococcus, stabilized with a special agent BDDE and repeatedly purified from residual decay products and endotoxins. Such preparation has an optimal visco-elastic texture, is evenly distributed within the dermis, does not cause discomfort or a feeling of distension under the skin, is characterized by a high degree of stability, does not migrate, or is visualized, providing the effect of a smooth and even surface.

Pros and cons of fillers

Based on the results of using the drug, it turned out that hyaluronate is able to replenish the missing volume in the tissues, in addition, it stimulates the production of its own hyaluronic acid, collagen in the body, which contributes to skin rejuvenation. But this benefit of cosmetology also had its drawbacks: not all clients had the effect after injections for a long time. We have our own hyaluronic acid in all our organs and tissues. And there is a specific enzyme that breaks down it - hyaluronidase. How quickly the filler biodegrades, that is, dissolves, depends on its activity. If the metabolism on the hyaluron is accelerated, then the effect of the injection will last from 2 to 3 months, with a slow metabolism - from one to two years. Therefore, manufacturers have created options for fillers based on polycaprolactone ("Ellanse") and calcium hydroxyapatite ("Radiesse"). These are drugs with a longer and more predictable result. True, they may not work on all areas of the face, for example, a hyaluronic filler is more often used in the area of the lips. By the way, collagen fillers are not a thing of the past and are still used in cosmetology practice to correct scars. Fillers based on hyaluronic acid are the key to successful correction and long-term results Hyaluronic correctors are in the arsenal of almost any manufacturer of cosmetic products, and each brand will emphasize its benefits. At first glance, all spies are similar to each other, but when your own appearance and health are at stake, it is very important to correctly approach the issue of choosing a brand. Of course, the procedure should be entrusted to an experienced and qualified specialist, but it does not hurt to have sufficient knowledge about the types, advantages, and disadvantages of different fillers. So, the main criteria when choosing gels based on hyaluronic acid are phase, density, cohesiveness, and the amount of a binder. According to the combination of viscosity and elasticity, all products are divided into monophasic and two-phase, the choice of which depends solely on the individual tasks of correction and the characteristics of the patient's skin.

Filler side effects

Redness and swelling may occur after the filler is injected into a specific area. And if the first will pass in an hour or two after the procedure, then the second - in a week. During this period, you will feel the drug in the injection area - until it softens. Filler can cause particularly negative reactions in certain people. As with any medicine, fillers can be allergic. The doctor tells the patient about such side effects in advance when choosing a drug. Allergy is expressed in the form of severe redness and swelling in the area where the filler is injected. Such a reaction is corrected by the cosmetologist who performed the procedure. In rare cases, with prolonged redness and swelling, the drug is removed by introducing a special enzyme into the zone that dissolves it.
