Spells aren't going to change your physical appearance, such as hair length or eye color. Glamour magick just doesn't work that way, I'm afraid.
If you're having trouble with acne, here's some lovely home remedies: http://everydayroots.com/acne-remedies
I recommend adding some intent while you're doing it, and maybe even write a little spell, all to help it along.
For teeth whitening, I have family members who use a little baking soda and swear that it works wonders. Stay away from dark colored drinks, and brush twice a day.
Spells won't fix all your problems, but you can use them to help.
Everything that you are asking for have no homeopathic or magic fixes. Your hair will grow on it's own and you can dye it, there is no magic spell to change hair, or eye color. Get medicine either over the counter or see a dermatologist of your family doctor for your acne. As for the teeth whiting goes visit your dentist and use the proper over the counter products. Hope this helps and doesn't discourage you. Magic is a wonderful thing, just not a fix for everything.
Hair length: magick cannot create drastic physical change. Perhaps blushing your hair while visualizing your desired outcome might speed the process a bit, but magick cannot make your hair grow a foot in a night.
Hair colour: again, physical change by magick won't work because magick effects energy. If a spell calls for lemon juice to be put into your hair, then yes, but only because the lemon juice lightened your hair. Also, no one is born with pink, purple or other anime hair colours so magick can't change your hair green.
Teeth whitening: brush your teeth with baking soda twice a week. No magick will whiten your teeth.
Acne cleansing: off the top my head I can't recall ance effecting herbs but a healthy diet and a daily skin care routine can reduce acne. Genetics however play a big roll. Magickally, again, no physical change.
Eye colour: contacts. No physical change by magick.
I recently looked into binaural beats. I never tried them, but some people who tried it said it worked(Don't know if they are lies or what not). You can find them on youtube. Apparently, they work for physical changes such as: Eye colour, hair growth, pimple treatments, etc. If interested, google it.
That's why people must research on what they are about to embark on. There could be consequences. From what I've read, it could take months of listening to one of those to get what one desires. More effective if listening to one of those at a time, not multiple.
you could try a attraction spell of sorts to make people see you the way you want them to, its what i do when u go oat clubbing i am not a good dancer but dos not matter cause i do kind of a reverse attraction spell so people would not notice that
