Botox injections are most commonly used to improve the cosmetic appearance of both the face and neck area. They work by paralysing certain muscles within the face such as the frown muscle, which has the result of decreasing wrinkles and frown lines. Botox is extremely effective and the results typically last for about 4 months.As to whether you can drink alcohol after Botox injections then the answer is that there are no studies to say that you can’t. Typically practitioners will advise that you avoid excessive alcohol immediately before and after the injections as it can cause increased fluid retention, which may lead to more bruising.
As to whether the effectiveness of Botox can be altered by drinking alcohol, there is no evidence to suggest it can. There is no known mechanism of action of Botox that could in anyway be affected by drinking alcohol and consequently this is not a reason to avoid it.
In summary, it is always a good idea to check with your practitioner as to whether or not they would advise you to completely avoid alcohol both before and after Botox. The chances are however that they will just tell you to drink in moderation as is always the advice of a medical professional. If you recently drank after having Botox injections and are worried that the effects will not last as long as they normally would, then this is definitely not something that you need to be concerned about.
