I use FaceApp. And, you just take a photo of yourself, and then choose “gender”. This generally results in a female that looks like me to a large degree. I mean, I take the photo wearing a wig, so the hair is very much the same. And, my nose, eyes and mouth are the same. But, somehow the overall impression is that I am prettier. AND, I look younger. So, there is an age change button which I also select. The problem is, the age that makes me look my age also wants to put facial hair on me. So, I take the photo, do gender, then save. Then I take the filtered photo and load it back in, and age myself.
That’s pretty much it.
