Our skin is living thing too ! 
and will adjust to the body and take shape slowly over the period of time.
I have had two Cesarean-sections and have got back to my original shape within 6 months with minimal stretch marks.
Now may be these were due to the one or many factors that I took care of in my pregnancy.
1. I drank good amount of water.
2. Applied Shea Butter cream regularly.
3. Went to the gym after my 3rd month of pregnancy till I could manage.
4. Walked around and did everything myself as far as possible.
5. After my surgery healed, I joined back gym after 3 months! Yes! Initially I started with light weights and later moved on to heavy weights.
6. I made sure that I did mostly lower body workout only.
7. I kept the cardiovascular exercises to 10 min only.
8. I walked 30 min briskly daily before or after dinner.
9. A few years later I had again put on weight but recently managed to lose 8 kg in 3 months time. Again I did everything but with more intensity and difficulty. Mebbe cuz now my age mattered wrt the metabolism. Yes this time I do have stretch marks I did not apply shea butter at all. I am now starting on daily body massage with shea butter . Its working like a miracle. The skin is becoming taut and firmer. Of course I am doing weight training and cardio too. I play badminton and football once a week. Water, food etc are as per my BMI and height.
So moral of the story is … you will reap the fruits of all the hardwork with patience …. loose skin will become taut and firm but provided you work towards it too.
Remember it takes time to get back tight skin especially on the face after a drastic fat loss. But it’s not impossible.
Also there are special face massage and creams that work if applied correctly. And if nothing works there is the DOCTOR like the famous line from our very own bold gal Rakhi Sawant.
I am now working on face muscles and skin too. May be will write an article soon on that too. So keep reading and subscribe to the site.
