Should my Doctor Have Sterilized my Skin Before Injecting Juvederm?

The value of antiseptic cleansing on percutaneous injections is intuitively supported but, to the best of my knowledge, there are no established studies documenting the absolute need or the potential complications of simple cleansing/wiping off of the surface.

 In most cases, it is sufficient to wipe the area with an alcohol pad before injecting - the utility of this really is not certain either.  There really is no need to "wash" your face unless it is very dirty or there is a lot of caked on makeup.  Good luck.

I always prep the skin with alcohol, I think that is appropriate and minimizes the risk of infection.

To prevent infection, sterilization of the skin is not necessary - I certainly would not fault any practitioner for doing so, but there is no evidence to suggest that sterile technique for filler injections decreases the already very low incidence of infection with this procedure. Prior to filler injections, I prefer that any makeup, moisturizer or medication be removed with cleanser/water. I then swipe the areas I am injecting with an alcohol swab.

It is better in general to get makeup off, and use alcohol to sterilize the skin.  If you did not suffer an infection or other problem, no harm no foul.
