Social Downtime After Blepharoplasty?

Great question.
It depends on whether you're doing just upper lids or considering either lower lids alone or upper and lower lid together.
Upper lid surgery typically has a quicker recover than any surgery involving the lower lids.
In our San Francisco area practice we explain to patients that upper lid blephs are usually done as outpatient surgery meaning patients go home the same day. The first 24 hours cool compresses and head elevation help reduce swelling. Typically some pain medication may be required for the first day or two. We recommend reduced levels of activity for the first week to lower possibility of bleeding complications.
There are sutures that are typically removed day 4-5.
Patients usually are a bit bruised and swollen for about two weeks. The incision line may be slightly red and raised as it heals for the first month.
Socially patients are usually fine to go out and about shopping with sunglasses after the sutures come out.
Most patients can camouflage any residual bruising with light makeup at 10 days.
Lower lid blepharoplasty can involve more swelling and bruising and has a larger occurrence of black eyes. We usually explain to patients that having the lower lids done will add about a week to the recovery milestones (other than the timing of suture removal) listed above.
I hope this helps!

Blepharoplasty recovery varies from patient to patient and depends upon a large number of variables. Most patients feel pretty good in about two to three days following surgery, but their primary concern is when they will look good enough to go out in public. Recovery following blepharoplasty surgery may last for months, but most patients feel they can go out in public in about a weekIt's important to emphasize that recovery periods are variable and depend not only on the patient's wound healing characteristics and the surgical techniques utilized, but also the patient's tolerance for changes that may occur following blepharoplasty surgery.

Usually the downtime is 7-10 days, but it may be longer depending on how one bruises and the type of blepharoplasty you have.

I tell my patients not to plan any big social events (weddings, reunions, etc.) for 2 weeks after eyelid surgery. Most patients can go back to work within 5-7 days depending on the type of work.
Sutures will be removed around day 5 and most of the bruising and swelling will be resolved by day 7. Each patient is different and these times may vary by a day or two either way.
Not taking any medications that can cause bleeding, head elevation, cool compresses and taking it easy can help you have a speedy recovery.

On average, about 7-10 days can be expected due to bruising. Shopping with sunglasses on, three days; Dinner engagements, 10-14 days. All this will vary with age and inherent tendency to bruise more or less.
