10. If you’ve begun to see a softening of your jawline, spend five minutes every morning and night chomping as though you were chewing a piece of meat. This will strengthen the jaw muscles and create more definition. (Don’t do this if you have TMJ.)

Maybe a nice rawhide bone.
I believe it's Jenna Jameson who swears by two pieces of bubblicious at once to keep the jaw strong. Not shapely, but strong. Unfortunately, when I do that, my tiny skull takes on the appearance of being wider because of the built-up jaw muscles.
For chin and neck firmness (and overall core fitness) Callanetics, that 80's craze few committed to because it's murderously hard, work amazingly well.

start using a treatment product that contains hydroquinone
At that concentration, it's probably OK... but hydroquinone is known to be mutagenic. That's the rest of the world's go-to skin bleacher & lightener.
I like glycolic acid because I still have blemish and sebum issues, but I know it's a good chemical exfoliant/peel for any skin that isn't sensitive to it.
