FFS virtual simulation better then FaceApp
Instead of using FaceApp try
Virtual Facial Feminization (virtual FFS) software that I posted here some time ago.
You can simulate chemical skin peel resurfacing and blemish remover,Laser skin resurfacing,jaw and chin contouring,brow boss shaving, hairline modification, cheekbones augmentation,face lift and much more ect.
These things are what you would look like with FFS.
You can also try CatFish makeup Techniques!
I love FaceApp and Instagram and Snapchat filters.
