I have a regular version of FaceFilter, today's GOTD, that was included when I bought a copy of PSP X5 towards the end of 2012 [for $23 - I looked it up]. Haven't used it much -- put it this way: having long ago removed PSP X5 [I'm using X8], I wasn't sure it was still there, or if it worked [it does]. It was apparently updated at least once -- the newest files are dated 3/6/2013, the same as today's GOTD. So I took to Google, looking for any updates, info, & such, not finding much that was relevant, but stumbling on a editing tutorial that I thought was interesting enough to share.

It's not the best nor the worst I've read -- you might agree or disagree with some or even all of the author's steps, but it includes some methods [tricks?] I've not seen before, so personally find it interesting. Yes, it is P/Shop-centric, but most all of it can be adapted to other image editing software. If your software doesn't have layers, maybe check out The GIMP -- portableapps.com hosts a portable version along with an add-on to make it more Windows user friendly, so the only risk is your time. Do note that it will take a while 1st time you start it, but not so much after that.
And in case it's of any interest or useful at all, here's what I posted on the FaceFilter download page...
----------------
I didn't see a lot of recent news or reviews for Reallusion's FaceFilter -- I got it as part of PaintShop Pro X5 Ultimate [on sale then for $23] back in November of 2012, & most of the stuff I found with Google dates to around that time [2013]. One reason I didn't see much of anything for 2015 or 2016 could be the popularity of using the camera in your cell phone -- it's easier to edit or touch-up those photos right then & there, since you're already previewing the shot. Typing in face touch-up in the search box at the Play Store supports that theory, with loads of apps available showing 4-5 stars [out of 5]. And by necessity they're pretty much all super easy to use -- you've got a small screen, limited processing horsepower, & most likely are limited to touch [rather than something more accurate].
Another *maybe* trend I spotted using Google is that there's less pro level discussion on facial touch-up, beautification, glamour shots etc. than I'd seen just a few years ago. That *might* be due to a combination of ethics & political correctness. With the power of all the tools at their disposal, many [most?] photographers set their own limits on how far they were willing to go, & that's the ethics part. Political correctness comes in with debates & discussions about fostering unrealistic standards & poor self image. As far as us everyday sort of people, while no one minds you removing a zit, you can get in serious trouble getting carried away, e.g. giving someone a digital nose job -- "What! You think it's Ugly?"
That out of the way, there are 4 types of facial touch-up -- FaceFilter gives you 2 of them, along with a collection of more general image edit tools like White Balance. Of the 2 methods that FaceFilter doesn't specialize in, the somewhat blurry dream look, is maybe the easiest, & least likely to offend -- you're not changing any actual features, but presenting them in a softened, more forgiving way. The 2nd is frequency separation... it gone from being very popular to a standard part of editing routines. Basically you separate texture & color, then edit one or both before merging them back together -- the advantage is that you can still have skin [or fabric etc.] texture in your edited photo. Preserving that original texture is not always considered important.
Where you lose that texture is with healing tools &/or painting -- anything that alters groups of pixels other than just changing their tint. And that's one of the types of facial touch-up FaceFilter gives you -- there are several ways to paint on your image. And FaceFilter can make it loads easier to do stuff like paint eyebrows. The 4th type of facial touch-up is to change the physical characteristics of the face, e.g. the digital nose job, and FaceFilter offers that too.
As far as the app itself, if all you're after is a slighter, just overall enhancing of a facial image, the Android apps may be the easiest way to get decent results, at least most of the time, & particularly with shots that are less staged. At the other end of the spectrum, you're not going to see a crowd of experienced P/Shop or GIMP users working with FaceFilter either. FaceFilter is for the folks who don't mind spending a bit of time learning the software, who want to add a bit of glamour to their portraits, but who just don't want or need to go more full tilt using P/Shop of The GIMP etc. The learning requirement isn't because FaceFilter is hard to use, but because it's so easy to go too far, producing images that are too unrealistic, that no longer look like photographs.
Depending on your personal style of photography & editing, & how you use FaceFilter, it's possible to get very nice results, comparable to what you'd get using apps like P/Shop or The GIMP, but again it depends on what you're after, & what your style is. I've seen some lovely face shots where the skin texture played a very important role, & you're not as likely to get something like that out of FaceFilter. I've also seen high end pro face shots where the face looked caked or layered in makeup, kind of like the people you see on TV who do have layers of makeup applied. If that's what you're after, &/or don't mind, you can do that in Face Filter. Where you're more limited compared to P/Shop or The GIMP etc., is that you can't treat the rest of the photo so well, & that has an awful lot to do with the overall impression or presentation of the face or portrait, but FaceFilter was never designed for that level of editing.
Installation of the software probably isn't too bad, *I Think* -- in a win7 V/Box VM it triggered over 260k new registry entries, most of them temporary, but far too many to weed through looking for those that are not, while it refused to install in my XP Mode VM. It does add C/C++ runtime files from Microsoft, & some of them are older versions. It also adds ~200MB of files to Public Documents -- mostly templates, the copy I have installed doesn't see them after moving that [Public Documents] folder to another drive from the SSD where I have win7 installed.
Last, I have no idea what they're talking about when the reference DSLR stuff in their ad copy... Some version of FaceFilter is supposed to import RAW image files in the DNG format -- today's GOTD will not see them. [The DNG format itself is not what you'll likely get using your camera -- I convert the .ORF files from my Olympus camera to DNG with DxO Optics Pro.] Other than that I don't see anything that would be any different from editing any image in most any software.
