Buying Restylane Online and Injecting Yourself?

Restylane and all dermal fillers like it (anything that is injected through the skin for that matter) are prescription products that legally can only be sold on order of a prescibing physician. So if you are not a doctor and are able to purchase Restylane online, someone is breaking the law. Either the product isn't really Restylane (this is quite likely) or someone is breaking the rules by selling it. More importantly, good results with dermal fillers require experience, training, sterile technique, and the ability to manage any potential complications. This is not a do it yourself product!

Very bad idea. Very bad.  Aside from the fact that you risk paying for a product that may be counterfeit or contaminated, without having a knowledge or understanding of facial anatomy you can potentially permanently disfigure your face.  It's just not worth it.  Don't risk it.

It’s always a bad idea for patients to perform
self-diagnosis and self-treatment.Without appropriate training this approach can result in therapeutic
disasters.Injectable fillers require a
unique skill set and specialized training.Without this skill set complications are inevitable. It’s
also illegal to obtain Restylane without a medical license.If you’re able to illegally obtain Restylane
there may be quality control issues as well.In some cases, the material may not even be sterile. Based
on these considerations, self-injection of fillers is a bad idea.Not only is there the potential for poor
aesthetic results, but there’s also the potential for significant
complications.If you’re considering
Restylane, the safest approach is to consult a board certified specialist who
has experience in this area.

This is a really, really bad idea.  First, you do not know what you are getting through the internet.  There are lots of dangerous imposter drugs and materials out there.  It is also illegal to purchase these items from out of the country, (which is where most of these sites are).  Next injection yourself is also a very bad idea.  One needs to know the anatomy to avoid potentially serious pitfalls.  The angles that one needs and feedback are also compromised.Please see an experienced injector.

Most things these days can be bought over the internet - whether it is legal, pure ingredient, sterile, not adulterated is a big worry but not the biggest. The biggest danger is you !
A Doctor Who Operates On Himself Has A Fool For His Surgeon is the corollary to: A Lawyer Who Represents Himself in Court has a Fool for His Attorney. Both o these maxims involve highly trained persons. Just imagine how bad it would be if they were not.
THIS IS JUST WHAT YOU ARE DOING !
Not to mention practicing medicine without a license which is illegal in all States in the US. It is downright dangerous and you are highly likely to have complications too numerous to list.  It just isn't worth it.

To self inject is not a good idea. Restylane is a controlled drug that requires a doctor to obtain the product. Online sources are either illegal or the product is not really Restylane. Injecting Restylane requires education in injection techniques and experience.  So it would be illegal and foolish to order and use an online product.
