I had asian double eyelid surgery with a parallel crease 3 weeks ago, does scar tissue go away over time? (photos)

Preop shows minimal asymmetry. Very slight (if any) ptosis on the left side, which is the side with the issues. At this stage, looks pretty symmetric and healing on schedule. Hang tight, I suspect you'll have a nice result.

Thank you for your question. You are asking if scar tissue from Asian double eyelid surgery with a parallel crease goes away with time. You had the procedure done 3 weeks prior, and only the right upper eyelid is folding into the crease, while the left is folding above the crease at the scar tissue.
I can certainly help you based on your photos alone, and give you so guidance in the absence of a physical exam. I’m Dr. Amiya Prasad. I’m a Board Certified Cosmetic Surgeon and Fellowship-trained Oculoplastic Surgeon. I’ve been in practice in Manhattan and Long Island for over 20 years. I’m well known for my work with Asian double eyelid surgery for both primary and revisional surgery to correct work of other doctors.
The swelling that is making is your upper eyelids look wide, and making one fold look higher than the other will decrease with healing, and your eyelids will look more even eventually. At 3 weeks, you are still in the proliferative stage of wound healing, where there is still a lot of fluid in the eyelids that need to clear, and collagen fibers are still disorganized. Your picture show your healing is going well, and nothing looks out of the ordinary. As you pass the first month after surgery, you enter into the remodeling stage of wound healing, where collagen fibers start to flatten out, and most fluid has been cleared from the upper eyelid. Some swelling may linger for a few months, but most swelling resolve within the first month. The rate at which swelling dissipates can differ from one eyelid compared to the other, especially if more skin or fat was removed from one compared to the other. Full surgical healing generally takes about a year. I usually take before and after pictures of my patients around the six month point as final results are pretty close at this point, but healing does vary with surgical technique, type of anesthesia used, and the patient’s capacity to heal.
While you do look like your healing is going well, it’s still important for you to follow up with your surgeon. Pictures don’t replace a physical exam, and your surgeon knows details of your surgery, so they can best determine how your recovery is going. I usually see my patients 2 weeks after the surgery, then after the first month, then at three months to monitor healing progress, but I’m always available to them to call if they have any concerns. I hope you found this information helpful. Thank you for your question.

Thanks you for questions. 
Considering immediate post surgery, you are healing beautifully. Scar will go away and fold will be on the crease line. It is quite common at this stage of recovery, crease may not exactly match but once healing is taking place and swelling subsides, crease will be formed. You are in good recovery stage.
