Well first you have to want to start FEELING attractive on the inside and out.
People do all sorts of things to feel more attractive -- get a good hair cut and start taking good care of our hair, wear a little make up, exercise every day, eat a healthy diet, practice self-contentment and be grateful for what we have and the wonderful things we see in the world around us.
And you can also do facial massages on yourself or go get one. YouTube has a lot of facial massage techniques.
I also want to say that, a person who is content and feeling decent on the inside, shows it on the outside.
