The Duchess of Cambridge's £55 baby body fix Forget French corsets, personal trainers and diets, the royal household calls upon this slimming and sculpting skin cream duo from Karin Herzog to keep one's post-pregnancy body in shape. Far be it from us to utter a word about post-baby body workouts so soon, but there is one slimming and sculpting regime which the Duchess of Cambridge has already been following. It has been reported that the royal household has been calling upon Karin Herzog's Dynamic Duo to keep the Duchess in perfect shape. And while it may sound like a couple of pumped-up personal trainers, it is in fact two tubes of skin slimming and smoothing cream, Silhouette and Tonus B12, costing £55.

She is a long-standing fan of this oxygen-based skin range from Switzerland, but she isn't the first to use this particular duo to save her post-baby figure. Other celebrity mothers include Victoria Beckham and Uma Thurman, who both used the Dynamic Duo to tone their thighs and bottoms after having their children. Karin Herzog say that Silhouette and Tonus B12, "significantly reduce the circumference of the thighs and buttocks when used in conjunction regularly." Their clinical results state that this 'Detox in a Box' improves lumpy, bumpy skin by 'blasting away toxins' and fatty tissue.

So we're reserving judgment. However, as the trio of famous mothers using these products look fabulous and have teeny-tiny thigh circumferences, that's enough for us. Silhouette and Tonus B12 by Karin Herzog, and as used by the Duchess of Cambridge.
