What Are the Best Methods to Reduce Facial Swelling Post Laser/fat Injections Treatment? (photo)

Follow all of your surgeon's post-care instructions and keep all of your follow up appointments to ensure that you are healing optimally.  Additionally, I would recommend cold compresses on the area and consider applying arnica gel topically as well to mitigate the swelling.  Ensure that you are resting/sleeping with your head elevated, staying properly hydrated and eating enough to keep your energy level up.

Thank you for your question!  
Yes, swelling is typical after a facial fat transfer and can last up to 3-6 months. I recommend platelet-rich plasma (PRP) to help improve final results. Icing the area, Prednisone, Ibuprofen and Venus Legacy treatments can all help reduce swelling. 
I suggest getting a formal evaluation with a cosmetic dermatologist.

The best way to decrease facial swelling in your case is to hydrate optimally and follow your surgeon's guidelines. Due to the fat grafting that was performed, that aftercare may differ slightly than someone who just had laser work done. ** Sleep slightly elevated also

Swelling to the point the eyes are swollen shut can happen with these procedures.  Head elevation and cold compresses can definitely help.  I would also consider a short stint of steroids as well.

Following your surgeon's post operative recommendations after a CO2 resurfacing is key. The swelling after a procedure with robust settings is impressive on its own, and when you lump periocular fat transfer on top of it, there's no surprise you are experiencing the kind of swelling that you are.Specific portions of the post operative recommendations and swelling include:1. Ice. Making sure you do no more than 15 to 20 minutes per hour, not placed directly on the skin. Your sensation may not be fully intact, and you do not want to provide a cold injury to your freshly lasered skin.2. Head elevation. Keeping your head above your heart, at about 30° when you are resting or sleeping, will significantly reduce the swelling that you notice - especially in the morning.3. Rest. Keeping your heart rate and blood pressure low, not bending over, etc. so I can help to reduce that amount of swelling that you experience.4. Steroids. Anti-inflammatory medicine such as this may be provided by your physician if they feel it is necessary, but this will depend on the other procedures that you had. In your case with the fat transfer this is not something that will likely be prescribed.

You are doing many things correctly. Here are some addtitional suggestions to reduce facial swelling:

Continued head elevation - sleep in recliner chair for up to the first week

Icing - not directly on skin, 20 min on then 20 min off if comfortable for the first 3 days

Low Salt diet

No heavy lifting, bending over or intense exercise

Be sure to strictly follow your post-op instructions, and visit your provider for a follow-up appointment. I also recommend keeping your head elevated and the application of cold compresses for swelling. Arnica is also excellent for preventing bruising and swelling. It is also important to apply a sunscreen with an SPF30+ in order to keep your skin protected. We hope to see you heal beautifully! Thank you for your question!

All of what you are doing sounds like you're doing the correct things. Largely the other suggestions provided by physicians are great as well. 
I'm not so much in favor of steroid injections as others have suggested. Possibly some mild oral steroids may help. When injected into the site they tend to negatively impact the fat transfers. 
If general skin irritation persists more than a day or so more, it is likely you're reacting to the aquaphor. If so, switch to simple Crisco you can buy at any supermarket. 
Post sloughing, you can switch to a good silicone based moisturizer, preferably with scar reducing growth factors. This will be much more comfortable.
Remember to keep out of the sun. Lots of good quality high SPF sunscreen if you must go out.      
Wishing you an incredible outcome!
Warmly,

swelling after fat transfer is seen. if it is hot or too tender see your physician. rest, ice pack or the spoon that was held in freezer can decrease swelling. if persistent see your doctor and medications to decrease swelling can be used. 

as other doctors mentioned keep head elevated when in bed. 

The swelling can be improved with steroids. But this could affect the survival of fat under your eyes. If you are patient, the swelling will come down really fast that first week. Keeping your head above your heart at all times during this earlier period can also help.
