Can Restylane Be Dissolved Few Days After Injection?

The great thing about Restylane and all of the hyaluronic acid fillers is that the treatment can be modified after the fact with hyaluronidase, an enzyme that breaks down the hyaluronic filler.
However, swelling after a Restylane treatment is normal and especially when you bruise. The incidence of bruising varies quite a bit but if it happens to you, it was a 100%. The blood that makes the bruise causes its own swelling. My best advise is let the bruise fully resolve before making up your mind regarding the treatment. The bruise is not fully resolved until all visible traces of the bruise are gone plus three or 4 days.
At that point, a decision regarding your treatment result can be made. I generally find that it is impossible to assess a treatment result until this point. So don't panic now. I think the biggest issue is if you did not expect to be bruised and swollen after the treatment and now suddenly you have to explain to the inquiring world (you know who they are) what you had done. These are not really zero down time treatments.
If the bags persist, then I agree, something will need to be done. I find that some people have very poor lower eyelid skin i.e. very thin skin. This type of skin does not hide the under eye Restylane treatment well and takes a prolonged time to settle. Generally, I advise a chemical peel for these types of individuals.

It sounds like you may have some edema due to a compression effect on the lymphatics that drain fluid around your eye.  The bruise is likely worsening the problem.  I would give yourself at least 2 weeks before considering any method to remove the filler.  The swelling may improve over that period.  Although swelling and bruising can happen with any injectable, filler use around the eye requires a skilled, board-certified physician.
