As you said, one cannot spot feminize their face, with herbs.

Depending on your age, skin condition, hair status, and such, there are a number of things that you can do to feminize your face without any herbs or whatever. 

Grow your hair and get a feminine hairstyle. If you have short hair now, maybe start with a Pixie cut.
Put some highlights in you hair. 
Pluck your eyebrows to a feminine shape. Have a pro do it, if possible.
Get your ears pierced.
Get rid of all traces of a beard. 
Get your face as flawless as possible. If you have acne or blemishes and cannot treat them yourself, find an Esthetician for laser or other facial treatments.
Wear light mascara, a matte lipstick that matches the natural color of your lips, a touch of bronzer or blush. Or, maybe just some Cherry Chapstick!

Smile more and tilt your head slightly to the left or right shoulder when speaking to others, not straight up.
Study and adopt feminine postures. Use your eyes to communicate. Do not make big gestures or take up a lot of space.

Do as many of these things as you can... it might be enough for you.
