Hyaluronic acid injections are used worldwide mostly for filling in facial wrinkles and folds. They have an excellent safety record when performed by qualified medical practitioners.
They have been used successfully in the penis for some years (Moorgate were the first clinic to introduce them to the UK for penis enlargement).
No previous skin test is required.
The most trusted hyaluronic acid product for the penis is Juvederm Voluma. This is the only HA product offered by Moorgate.
Results last 12 to 18 months, but in some cases, the product can re-absorb more quickly than this. We cannot know in advance how quickly or otherwise your HA will absorb; this is entirely down to your own metabolism.
HA injections are the most expensive penis thickening option of all. This is because of the temporary nature of the filler. The medium-term thickening option is a bio collagen stimulator such as Ellanse and the long-term option is a fat transfer.
