Can i use palmers cocoa butter for tightening on my face?

A lot of options: You can first try staying out of the sun as often as possible, always wear sunscreen, don't smoke, get a good amount of sleep, sleep on your back, try not to squint, if you need reading glasses get some, don't over-wash your face, use a moisturizer, lay off the coffee and try cocoa instead, and eat healthier foods. I hope this helped :].

Cocoa butter: ...Is one product that is helpful as a moisturizer, but it will not "tighten" anything.
