Friend's weight and skin problem

One of my friends who has a weight and skin problem asked me what's the best way to shed those bunch of kilos of fats and also her irritating acne on her face.She look at the net and found the product called Lipovox.She asked me if it safe to use.I told her she should not buy immediately any product without consulting first her doctor.I just told her she has to go to her dermatologist for her skin and to her doctor or dietician on her weight problem.It's better to be safe.
