Hello Interloper!

Times move on and the hyaluronic acids were the new kids on the block. With no requirement for pre-testing in case of allergic reactions, the HA’s offered a somewhat more natural, non-animal alternative (i.e. collagen derived from cows versus HA derived from bacterial fermentation) which many patients and practitioners alike preferred the sound of. The other attraction of HA’s of course is that they can be easily reversed if the practitioner incorrectly places the product as the hyaluronic acid can be dissolved with the use of hyaluronidase – a Godsend for some!
Founding member of the British Association of Cosmetic Nurses, Liz Bardolph RGN said;
“Collagen was a great product and was the gold standard for years – it was like injecting liquid gold. Not all patients like or can tolerate the HA’s and for this group, it was reassuring to have a product that was a tried and tested alternative. However, skin testing and longevity was a problem for many.”
According to the American Society for Aesthetic Plastic Surgery (ASAPS), the use of collagen in the United States, among its members, has been on the decline for many years as illustrated in the chart below, with significant rises in the use of other products including hyaluronic acids and poly-l-lactic acid.
