In general, preventative treatments for facial aging include
sunscreen, minimizing sun exposure, abstinence from smoking, a healthy diet,
and a good skin care regimen that includes retinol or tretinoin. Besides that, genetics and age are the
primary drivers of skin aging in the lower lids. When lower eyelid aging becomes bothersome,
non-surgical options such as filler can be used to disguise the tear trough
deformity. Surgical options include fat
transfer to the lower lids, or a lower lid blepharoplasty. I would recommend that you consult in person
with a board certified plastic surgeon.
Unfortunately there is nothing specific that can be done to prevent eyelid aging over time. In general, avoiding sun, abstaining from smoking, and living a healthy lifestyle often helps to prevent many of the skin related aspects of aging. Early use of skin care products (vitamin C, fuit acid creams, among many other options) and preventive peels/microdermabrasion can also add longevity to skin health.
Best of luck
