i haven't smartphone and since instashit and FB and all the rest i see a lot of profile of girls like that for the record it's a pornstar never mind just a example
thumb_MadisonKnight_IMG_20190208_144552_824_1549662641.jpg they look very formated all,does it's works like photoshop or gimp and in the reality even if the girl is not completly ugly for sure,they are not ultra-beautifull high maintenance 15/10 but more 7,8/10 max, i have tendency to avoid this kind of profiles(not the pornstar don't care) but maybe it's just the fashion wave i mean they are maybe not all the same on an ethic way, prefer webcam or numeric cam shots it's more near of what you see IRL i have myself a fujifilm a good one as digital device so i have some notions of colors,gammas contrasts etc...all the girls looks yelloish/orange and very flawless with big eyes betty boop style,sorry i have a nother french word in mind "yeux de biche" means hind's eyes,if you know a bit snapshit instathing and all the new useless girly things tell me

It’s a filter. Basically, you can apply a “look” to your picture as you’re taking it. It takes the pressure of needing to wear makeup to look perfect, and they’re fun to look at.

Is your question asking why girls choose to use filters for their pictures that look completely unrealistic?
