Hi Aninka,Coffee is a vasoconstrictor and could potentially affect the blood vessel and oxygen delivery to the skin flaps of a facelift - or breast lift, or open rhinoplasty, or any secondary procedure. It is unlikely one cup of coffee would cause damage, yet I would talk to your plastic surgeon. Not all facelift are done the same way. Mini-facelift are less at danger of this healing problem but the results of those mini-procedures tend to be less too.Worse vasoconstrictors are nicotine, as you likely know, and some street drugs.I do a complete 2-layer facelift in Toronto, with SMAS, with wide undermining, fat grafting to face and often a chin implant is added. With this composite procedure, I prefer patients to abstain from tea, coffee, chocolate, nicotine for some time pre and post surgery.I hope this helps! Best regards,Dr. Marc DuPere, Toronto Aesthetic Plastic Surgeon
