I want to learn more about what kind of ingredients are good for your skin. Like with facials and beauty stuff. Where can I go to learn about that? I would really like to learn this stuff and maybe somehow get a business going.Where can I go to learn about skin and beauty care?
Cosmetology School and Take the Esthetician course.Where can I go to learn about skin and beauty care?
tthe doctor, spa, hair salon, mom, sisters, aunts,,,ppl like that. the doctor is never ever wrong and spa ppl make their living on perfecting skin. at the right hair salon, none of the cheap stuff, they have great products and a wealth of hair info. your family is great for tips on what they have tried and they know more about you and most likely have the same skin and hair issues as you.
Maybe some books? There's a great book by Sephora that teaches you about beauty (make up tips, skin tips, hair tips etc.). I think that would be a good place to start to see if it's right for you.
Well i'm not good at that stuff but i would suggest a make up place like sephora or grown up place that sells make up. They may be able to teach you some tips for a good buisness.
