Can it be reversed if I don’t like the result?

Yes, Hyaluronic acid-based filler procedures can be reversed by dissolving them away.

As explained in the section What is Hyaluronic Acid, an enzyme called Hyaluronidase can be used to dissolve Hyaluronic acid-based fillers into water, after which they are safely eliminated from the body. This can be done at any time.

This is one of the main reasons why Hyaluronic acid penis enlargement is a safer approach to penis enlargement than other methods.

In the unlikely event you wish to return to your normal penis size, you can do so by either waiting for the filler to dissolve naturally or by injecting an enzyme to dissolve it away.
