Smoked weed 2 days after Bellafill... would this hinder my desired results?

In my opinion, smoking marijuana after a Bellafill treatment should not affect your results.  Bellafill treatment normally does require several injection sessions spaced over time to produce gradual results.  

I have not seen any studies or information that this can affect the results.  I would recommend not smoking weed (if allowable by state law in your area) or nicotine for at least 2 weeks to be on the safe side while the body is reacting to the filler.  I would ask your treating dermatologist how they feel before smoking any substance (if legal), different physicians have different feelings toward smoking when it comes to affecting fillers. 

Using marijuana (smoking weed) two days after receiving Bellafill injections is unlikely to directly hinder your desired results. Bellafill is a dermal filler primarily composed of polymethyl methacrylate (PMMA) microspheres suspended in a collagen gel. Its effectiveness and longevity are not typically affected by the use of marijuana.However, it's essential to keep in mind that smoking marijuana, like any form of smoking, can have potential effects on the skin and overall health. Smoking can decrease blood flow to the skin, which may affect the healing process after any cosmetic procedure, including dermal filler injections. Additionally, smoking can contribute to premature aging of the skin and may impact collagen production over time.If you have concerns about the effects of smoking marijuana on your skin or the results of your Bellafill treatment, it's best to discuss them with your healthcare provider who administered the injections. They can provide guidance and recommendations based on your individual situation and medical history.In general, maintaining a healthy lifestyle, including avoiding smoking and following proper skincare practices, can help optimize the results of cosmetic procedures like Bellafill injections and promote overall skin health.
