I think the jury might be out on this issue .... do lotions and potions really help firm saggy skin?
I tend to side with the opinion that once stretched, nothing you rub on can restore the firmness that was there before because the elasticity has gone. However, I've heard that the massaging action itself is what can help improve the APPEARANCE of wrinkly skin so in that case, anything that facilitates a smooth massaging action should help.
Some people swear by dry brushing (I don't do it so perhaps someone can elaborate) I think it's all to do with stimulating the blood supply to the surface of the skin. Could be worth a try.
Personally, I'd carry on with the cocoa butter
