I'm 28 and my Face Looks Like It's Melting What Should I Do? (photo)

No, You are not melting. However, you have lost some volume. Have you lost weight? Do you have an overbite? Weight loss can lead to volume loss. You have a receding chin and that might be do to a dental alignment issue so if you have a bite problem , have that checked. that being said, you are a great candidate for fillers so if this bothers you get a good doctor and go for it. 

It is not likely that your face is melting.  However, some support with injectable hyaluronic acid fillers which are non surgical can make a huge difference for your self-confidence.  While exercising is great for your help and physique, facial muscle exercises will not correct your facial concerns.

Unfortunately you have lost volume about your lower face; be sure your diet is devoid of  all processed sugary covenience drinks and sodas, yes, even if diet soda; have  HA fillers done every 6 months until your volume is restored by an experienced cosmetically trained physician. Then, maintain your ongoing correction using topcial vitamin C; I like the Skin Medica cosmeceutical product line. Remember, a  successful outcome is dependent upon a realistic strategic plan for correction outlined by your physician and adhered to by you.  Good Luck.
