This all depends on your exam. Without a photo or examination I cannot give you a specific answer. One of the indications to do surgery on young patients is for eyelid drooping (ptosis) which can run in families.
See a board certified oculoplastic or plastic surgeon for an evaluation and recommendations.
The upper eyes and brow are a complex area of the face. Treatment depends on a number of factors. In other words, depending on your examination, you might need a blepharoplasty alone, a browlift alone, or a blepharoplasty AND a browlift. Ptosis repair is also part of the treatment plan if needed. That's why you need a thorough consultation. Posting your picture would have helped in giving you some suggestions as to what treatment you would be appropriate. I wish you the best.
Often heavy eyelids do run in the family. A photograph would be helpful to comment on. 24 years old seems rather young for upper eyelid surgery so unless the overhanging skin is interfering with your vision by means of it covering part of the visual field, or the skin is sitting on the eyelashes, you can wait until it becomes a medical issue. If your eyebrow elevating muscles (frontalis) are strong enough, they can usually compensate for the excess skin for a quite a while, by you automatically raising them a little to lift the skin up off the eyelids.
Dynamic examination is required by an oculoplastic or ophthalmic plastic reconstructive surgeon, who is an eye doctor (ophthalmologist) especially trained in eyelid assessment and surgery.
It's impossible to make a recommendation with any specificity without seeing photos or meeting someone in consultation. 24 is relatively young for blepharoplasty but this is not unheard of. Your best bet would be to seek consultation(s) with surgeons in your area to determine if you are in fact a candidate for eyelid surgery. If you have a droopy eyelid in addition to excess eyelid skin you might require ptosis repair which is a procedure that is distinct from an eyelid "lift." I hope this answer is helpful.

You need to post your photos to get an informed opinion or even better arrange a consultation. Droopy eyelids can have many components including issues with the brow and excess skin of the upper eyes and issues with the internal muscles of the upper eyelid. Different surgical techniques and non surgical options are available to help. It depends on what your priorities are and what you wish to achieve. The most important is whether you have ptosis and internal issues with the muscles of the eyes causing ptosis, whether removing the excess skin will drop the brow and whether the brow can be lifted to help the hooding. There are many options and you are best to arrange a consultation.
