Experts from Huizhou Peng 'ai Hospital said that the asymmetry of bust size is normal. In fact, this is only a phenomenon in the process of individual development and will not have any impact on the body. However, for many unmarried women, in order to make their figure symmetrical, their marriage life more harmonious, and to prevent their close lover from discovering their own defects, it is recommended to do hyaluronic acid injection breast enhancement surgery. Hyaluronic acid injection breast enhancement is based on the principle of non-invasive injection. Macromolecule hyaluronic acid is injected under the breast (between the breast and pectoralis major) or subcutaneously, so that the chest becomes stiff and almost no trace of the wound can be seen, and the fullness of the chest can be immediately presented. Hyaluronic acid injection breast enhancement is very safe at first, without surgery. There is no trace on the chest after injection, and there is no flaw at all.
