As brow lift surgery at the Cadogan Clinic is such a straightforward and safe treatment, any risks associated with this procedure are minimal and include forehead muscle weakness which is very rare and temporary. However, the risks associated with having a general anaesthetic are the same as any other procedure - your surgeon will run through the procedure with you in detail at your consultation and answer any questions or concerns you might have.
As for downtime, your surgeon may advise for you to take a week off work depending on your case as you may have minor swelling and bruising, this usually subsides after around 7-10 days after which you will begin to see your results, the improvement only just get better with time and after around three months post-surgery you will see your final results.
After a couple of days following surgery you will be up and about but it is important to be gentle with you face as skin may still be numb. If you feel any unusual discomfort, your doctor can provide pain relief for you, although this is not always required.
