Preperation- h???

I’ve been reading a few posts about the use of preperation-h… and i have heard the use of it for actors under the eye but as for fitness girls using it for weeks before a show to increases the tightness of there abs… i was wondering if using it for a period of weeks would have any real affect on the tightness of your skin or localized water release or fat burning??? any tricks or suggestions would be appreciated…someone told me to use this with some adipo caps and rub it on the area…
