Top Slimming Creams - Are They Worth it?

With our summer holidays growing closer & closer the emphasis really is on to try & get beach-bod confident!! We're all suckers for the cheats way to do this, even if we are all members of our local gym & the sales of slimming & firming products quadruples at this time of year!!
I've been looking at what are heralded as the top slimming creams made by cult brand Rodial, they'll set you back a cool £95-£100 so are they really worth it??
Firstly Tummy Tuck, this is proven to reduce the abdominal area by 2-3cm in 8wks, it has fig extract and neuropeptides which break down fatty cells and boost the cell metabolism & help slim & tighten the abdomen. Next is the Body Sculpture which is a slimming & anti cellulite gel & will reduce the hip & thigh area by 1cm in one month, it says it breaks down fatty deposits, stimulates tissue drainage, firms & tones your skin. The testimonials are good with customers seeing a difference in the tone & firmness of the areas treated, however as soon as you stop using the product this difference will no doubt diminish, so not a long term solution to body confidence really.....
Whilst I think these products are good to assist with the summer diet & help give you some confidence on the beach, I think when it comes to spending £100 to loose 2-3cm in 2 months then perhaps cutting down on sugary snacks, drinking more water & getting out for 30min walk each day as well as a quick 10 Sit Ups might be better idea for the same results!?
