Light reflecting off of the injectable product can result in a blue discoloration in some. Superficial injections or areas where there is thin skin can be predisposed to this in some individuals. If superficial, we can use a small needle to help faciliate removal of the product. If a bit deeper it is often easier to inject a product called hyaluronidase to help “dissolve” it. Your doctor should test you for an allergy to this product prior to injecting it in greater quantities.
