Blepharoplasty or Brow Lift for Female Patient in Early 20s? (photo)

Interesting opinions by some other responders.  The question that must be answered before considering any procedure is, "What anatomic feature is causing the appearance of heaviness that I do not like?". When the responsible feature is known, then it becomes clear where to address surgical treatment efforts, or non-surgical possibilities.  

Brow shaping and upper blepharoplasty may help, and I would open the upper eyelid slightly by levator advancement because of your low marginal reflex distance.  Would consider lateral canthopexy as well to slightly raise lower lid margin.  Would defer brow or forehead procedure unless eyelid procedure incompletely successful.

Of course, this is only a guess based upon submitted photos.  Personal evaluation must precede formulation of surgical plans.

You have a straight brow and a naturally hooded eyelid, and your temples and brows do not have much fat. There are multiple attractive celebrities and other young people with this anatomy, but it makes it diffucult to wear many eye shadow styles and requires careful grooming of brows. If you've decided you want to pursue plastic surgery, then brow lift, volumizing, and upper blepharoplasty are all options, but I'd start with minimally invasive procedures and go from there. At your age, volumizing the temples and upper brows with fillers will provide more skin exposure for eye shadows and will look more natural than a brow lift. If this isn't enough for you, a small amount of skin removal from the upper lid would also help. Do realize, though, that you will be getting an improved version of your current lid shape, not a different shape over all. 

In my opinion, your eyebrows are very important in defining your facial expression and character. I feel a browlift would make you look surprised. From my perspective, I would perform an upper eyelid blepharoplasty to reduce the “hooded area” of the upper eyelids.
