Chanel Sublimage Fluid
When I interview celebrities about their must-have products, I sometimes get deja-vu. It usually involves a mention of Chanel Sublimage, which countless celebs (AnnaLynne McCord being the most recent) have praised to me in person. This fluid isn't like other anti-agers, because it goesn't contain high quantities of glycolic acid or harsh ingredients. Instead, it feels more like a pampering treatment, as the velvety-textured liquid plumps and smooths skin with Planifolia, a natural ingredient from Madagascar vanilla plants, which the brand harvests through a polyfractionating process that refines the botanicals to their most potent form. Users say it gives their skin an instant gorgeous glow.

Blinc Cosmetics
This innovative line of makeup and skincare products has drawn celebrity fans like Jennifer Lopez, Miley Cyrus, Jennifer Garner, and Jessica Alba. Creative products like a rub-on microdermabrasion stick and a liquid eyeliner that dries to a smudge-proof, peel-off strip are examples of the brand's popular offerings. Try the Blinc conditioning lash-primer, which does double duty as a lash moisturizer and lash extender -- let it dry to natrually lengthen and thicken lashes, then apply your mascara on top for instantly lusher lashes.

SK-II Skin Signature 3D Redefining Mask
Cate Blanchett may be the face of SK-II skincare, but that doesn't mean she can't play favorites. The SK-II Facial Treatment Essence and Skin Signature 3D Redefining Mask are two of her most beloved products from the line, based on a "miracle" ingredient derived from Sake. If you're looking to splurge on top-technology skincare, this is one of the best bets.

Biologique Recherche
This French skin and haircare brand counts both seasoned stars like Michelle Preiffer and Sharon Stone to young heartthrobs like Taylor Lautner and Channing Tatum as users. Biologique Recherche's Lotion P50 is a frequent celeb favorite -- the vitamin-enriched facial exfoliator tackles blackheads and excess oil with lactic acid and witch hazel.
