The magic of La Mer is in the "miracle broth" — a marine extract that heals skin cells. La Mer The Lifting Contour Serum, $320, contains even more youth-ifying algae (brown and blue in case you're curious) and peptides (also derived from the sea). Clinical tests showed a tighter jawline in only four weeks — which is seriously quick in the skin care world.

The idea of a V-shaped face is huge in Asia, and Clarins believes in the trend so much they named their lifting serum after it. The Clarins Shaping Facial Lift Total V Contouring Serum, $80, contains guarana and ginger to tighten the skin and define the cheekbones. And they even created a special application technique — like a facial massage — to help sculpt the face.

The secret ingredient in Clark's Botanical Cellular Lifting Serum, $355, is Swiss apple stem cell, which protects cells from environmental aggressors like pollution. (It's also the reason this serum is so pricey.) The lifting effect is thanks to an algae extract that binds to water and tightens skin.

Tata Harper calls this a "facelift in a bottle," and she's not far off. After just five minutes, the Tata Harper Boosted Contouring Serum, $185, starts to tingle and tighten skin. Two hours later, your face looks more toned. And after four weeks, jowls are reduced. While this creamy serum contains a laundry list of botanicals, it's the brown algae extract that really does the contouring magic. (Notice a trend? Lots of algae on this list.)

DHC Beauty Lift Essence, $49, feels light and silky, yet it's incredibly hydrating. It contains a peptide complex to soften fine lines and oat kernel extract to lift sagging skin — plus a slew of moisturizing ingredients that make skin look instantly plumper.
