Had chin lipo done 3 days ago. Results less pronounced now than the day after surgery. Is this normal? (photos)

The initial swelling peaks around day 3-5 so this is totally expected. The swelling will gradually go down and you result will improve.  

Yes, this is typical. You still have swelling, which can take several weeks to resolve. If you're concerned, I recommend following up with your surgeon. I hope this helps. 

Typically, the third day corresponds to the most swollen day. By looking at your day 1 photo, you should get an excellent result. A significant amount of this swelling will be gone in 1 week, but it will take 2-3 months to see your final results.

It's too soon to tell what your final results will be. You may still have swelling, which can last 3-6 months after your procedure. To speed up healing, you can try adding hyperbaric oxygen, lymphatic massage, venus legacy or exilis radiofrequency treatments. To improve final results, we will often do a kybella and ultherapy about 4-6 weeks after neck liposuction to get more of an outcome. See an expert. Best, Dr. Emer

What you are experiencing is rather typical. Swelling usually gets worse for the first 4-5 days then tapers after that. Consider icing frequently and stay in good contact with your surgeon. Good luck! 

Hello dear
Thanks for the question and provided information as well. 
Swelling
is normal at this phase of the healing process, be patient, it will go
down in few weeks, i recommend my patients use the bandage to give more
compression to the area. 
Good luck :)
