After hyaluronic acid injection, normal erection will not lead to displacement or deformation of hyaluronic acid, and will not produce unnatural phenomenon, because the erection of the penis is the filling and expansion of the spongy body, and hyaluronic acid is injected in the dermis and subcutaneous tissue layer of the skin, not through the white membrane that wraps the spongy body, and does not reach the spongy body layer, and the injection is even, so the normal physiological erection is not a problem. The appearance will also remain natural. In the process of intercourse, the sexual partner will not notice the injection of hyaluronic acid, but only feel an increased sense of penile fullness, and because of the injection of hyaluronic acid, the male ejaculation threshold is significantly increased, which can effectively prolong the ejaculation time, and will give the sexual partner a better experience, and will not affect the male partner’s orgasm and sexual pleasure. In terms of international medical progress, hyaluronic acid for penile enlargement is not a new thing; from 2004 to 2008, Mr. JongKim from the Department of Urology of Korea University School of Medicine started a comparative study on the change of glans volume and the effect on premature ejaculation after hyaluronic acid injection for 6 months and 5 years. In recent years, hyaluronic acid technology has gradually been widely used in penile enlargement with remarkable results. In addition, another question that many partners are concerned about is whether erection will be deformed after penis enlargement and lengthening with hyaluronic acid injection. Theoretically speaking, after the injection of hyaluronic acid into the penis, the normal erection will not lead to the displacement and deformation of hyaluronic acid, because the erection of the penis is the filling and expansion of the spongy body, while hyaluronic acid is injected into the subcutaneous tissue of the penis, and there is no interaction between them, so it will not cause the deformation of hyaluronic acid. However, after the hyaluronic acid injection for enlargement and lengthening, it takes a certain amount of time for the hyaluronic acid and the tissue to completely fuse, which is usually about one week. It is not recommended to have sex and masturbation within this period of time, because external force will lead to changes in the shape of the penis, resulting in unnatural and unattractive, so we suggest that you do not have sex within one week of the treatment of hyaluronic acid injection for enlargement and lengthening of the penis, otherwise it will lead to Therefore, we recommend that you do not have sex within a week of the hyaluronic acid injection treatment, otherwise it will lead to an unattractive state of the penis after erection.
