Hi lybrate-user, for loose facial skin there are various treatments available like rf tightening, vampire face lift (prp) and facial thread lift. These treatments can be used in combination for different indications. I will need to examine your face or see pictures so that I can guide th best treatment for you.
Apart from these you can also apply ega cream at night for face rejuvenation, apply for atleast 6-8 weeks to see visible results. Take care.
