What we did this year: Upper Blepharoplasty and a total of 3 syringes of fillers to give the face some structure and volume.

•Upper Blepharoplasty: Prem Tripathi, MD
•Filler: Charlie Chen

It was a quick timing from when I thought I wanted to get an Upper Bleph to the when I actually got the procedure. I wanted to maintain the integrity and overall visual make of the original look so it was important for me to find a doctor that specialize in a specific almond shape. My main agenda was to only de-puff and look more awake.

From my research, the Upper Bleph can take up to 6 months to a year to heal. I think presently, we're on the slower side of the spectrum because there are still redness and scars, but we're only about 4.5 months post op- so tbd. I may get some lasers done to help, will keep you updated on that.

-Not sure why I say "We" because it's only "Me" but it makes me feel good that you're on this journey with me; so "We" did a thing this year! ☺️😘
