for the most part they work, they could be considered a form of illusion magic though depending on the spell. for the most part, the ones i have and occasionally use involve some chant you say to Aphrodite while, say, washing your face. personally, i say it to Hathor, but i follow Egyptian deities.
these spells, keep in mind, don't automatically change your appearance. you can't say the chant, wash your face and poof you're Natalie Portman. from what i've noticed, from the one i use the most to clean my pores, if i haven't done it in a while, the next day or the day after i get a bunch of zits because the oil is coming to the surface, but a few days after that my skins fine.
It is right that a spell will not change your physical appearance or genes and DNA, such as: eye color, hair color, etc. This is very true. Energy manipulation and desires will not change your physical appearance or your genes and DNA. I agree with that Hexen, such things will not work for anyone who try that since spells are basically energy manipulation and direction...
However, as vanity said , there is a form of glamour spells which is known as something that works. So saying that it is not fully possible is not fully correct. The form is called: "Illusions".
Basically glamour spells are illusion, nobody says that they actually changes any part of your body or your actual physical appearance or DNA and genes. Such spells are known as putting and illusion on your self and other people around you.
A glamour spell will only change your opinion and your point of view about you beauty and appearance, same thing about other people who are around you. However, nobody said that this changes something actual about your physical body or appearance.
So this is why this is called an "illusion".
This is actually not a bad thing to do, yet it won't change anything about your genes and DNA but it will change your own mind and thoughts. This is actually even a helpful thing, because sometimes it is very important to love yourself and to think about yourself as beautiful - from the inside and from the outside.
A beauty spell can make you feel better about yourself and boost your confidence, and when you feel better about yourself, other people will be more attracted to you. If you take a closer look at the people you admire the most, you will usually find that they have a special inner beauty and confidence that far exceeds any outer beauty they may possess. Work on developing your inner beauty and you will never again feel the need for love spells and beauty spells. I know how trite that sounds, but there are plenty of people in the world who aren't traditionally "beautiful" but who are still considered extraordinary and special.
My personal idea is every body have his/her special beauty, there is no such thing 'ugly person' there is a person who does not take care of himself. Thus, you do not really need a spell. Just love yourself and believe in yourself and you beauty. If you do it, other people will start looking at you differently.
Thats a real nice thought aid. But we live in an incredibly shallow society for the most part. I agree that everyone has an inner beauty, but most people wont take the time to see it. If you dont fit in to society's standard of beauty a lot of people will judge you for that. Not fair by any stretch of the imagination. But until we all learn to see past the exterior, that is probably going to be the way it remains
