Sun damage, lack of sleep and stress are what Bank says may be contributing to Zellweger's uneven skin texture and tone. He recommends combating issues like these with products containing alpha hydroxy acids like Neutrogena Pore Refining Cream SPF 15, $13.99 or vitamin A derivatives, found in prescription Retin-A and Triluma, which will lighten and brighten skin. "You can also kick it up a notch with in-office procedures like light peels or the Fraxel laser," Bank says.

Even at 32, Reynolds has less sun damage and fine lines than most A-listers. Though Bank thinks he may have help from Botox and fillers, he seems to have taken good care of his skin with regular maintenance and sun protection. If you want to get a poreless-looking complexion like Reynolds', Waldorf recommends using a topical retinoid (like the prescription Renova) or an over-the-counter product containing retinol like SkinCeuticals Retinol 1.0, $48. Microdermabrasion used in conjunction with these creams will keep flaky, dry skin away. If you want a more aggressive (but still non-invasive) solution, Waldorf suggests Fraxel for discoloration and pore size (average cost, $750-$1500) and Thermage for sagging, wrinkles and pore size (average cost, $1,000-5,000).

Gibson is no spring chicken, but other celebs his age (like Tom Hanks) seem to have a smoother skin texture and a brighter complexion. Waldorf attributes sun damage as the cause for Gibson's deep-set wrinkles and leather-like texture. "Improvement would take resurfacing (like several sessions of Fraxel), filler (like Restylane, Juvederm or Radiesse) and sun protection," Waldorf says. Have questions about fillers? Get answers here. And don't forget to use a UVA and UVB blocking sunscreen everyday (try Avon ANEW Advanced All-In-One MAX SPF 15 UVA/UVB Lotion, $16.50).

Tyler's smooth, clear and acne scar-free face is likely due to a combination of "good genes and great sun protection," Bank says. Though she may have help from Botox, it seems Tyler's been doing all of the right things for her skin (not smoking, sunbathing, picking at her skin or extreme weight change — all of the things Waldorf says can prevent damage to skin). Make sure you don't commit these seven skin sins either, as they can wreak havoc on your face.

The flat, stiff smile Hatcher is sporting here suggests she may have had too much Botox, Waldorf says. And her large pores and sunken eyes are possible signs that Hatcher is stressed and lacks sleep. "And being too thin can create or exasperate many of these problems," Bank says. He recommends maintaining a healthy diet and body weight and making use of fillers and treatments like Fraxel and Thermage to tighten and tone the skin. If those options seem extreme, at the very least, use products containing peptides and retinol to help build collagen and smooth lines (try Rodan + Fields Anti-Age Night Renewing Serum, $89.)
