Rodial Bum Lift

I'm a big Rodial fan. I love their sleek white and metallic silver packaging, their cheeky names, and the fact that they're often recommended by dermatologist (and touted by celebs like Jen Aniston), doesn't hurt either.  For those not familiar with the UK line, it's formulated with anti-aging and firming ingredients notably Pomegranate Ellagic Tannin (collagen booster and firming agent). One of their stand-outs (and complement to Boob Job), is their Skincare Bum Lift ($130). No the cream will certainly not replace your squats, but Bum Lift -- which uses a peptide, wheat protein, and caffeine -- does have an immediate firming effect. I don't think there is anything that will actually get rid of cellulite (and I've tried an endless array of creams/gels including painfully textured ones from Clarins and super-smelly ones from Shiseido), but there is definitely an instant smoothing and firmness effect with this gel which makes it stand-out from the pack. To see full effect combine with exercise though!
