ITT: I teach you to be attractive af.
I assume all of you are fairly lean and muscular, otherwise that is the first thing you need to do.
The things that matter out of that is social skills (just read some shit online, it's not hard), height and face.
Height is not really feasible to gain. You could just lift in your shoes and you could try LSJL (not really any proof it works and probably fucks your joints for 0.5 inches gain over a year).
But here comes the fun part, the face! We got a few techniques here, some proven, some not so proven. Lets divide it into two sections, skin and muscles/bones. Skin is quite easy to take care off. Stay hydrated, use moisturizer, sun screen and vitamin C serum. If you really have skin (acne) problems look into tretinoin and niacinamide.
Now for the interesting part. Mewing is mentioned here quite frequently, so start off with that (lips together, teeth together, tongue in the roof of your mouth). If you want faster results add belt face pulling (bite on the middle of a belt, pull forward, outwards and upwards). To add more mass to the face (muscle and bone), start chewing tough gum for upwards of two hours per day. Adding facial exercises will further improve your face. The second and fourth exercise from this paper gives you great bang for buck. ncbi.nlm.nih.gov
In this review they look at some facial exercises to see if it's effective, but no conclusion can be drawn due to lack of studies. But they give a great outline on what is being used by professionals and that most likely work.

>Their study targeted various muscles of expression in the upper, middle, and lower face, by means of 6 exercises: (1) lifting the eyebrows and frowning the forehead, (2) approximating the eyebrows, (3) closing the eyes with strength, (4) protruding the lips, (5) spreading the lips, and (6) contracting the right and left cheek against resistance.
