I can tell you about Skin Care Tycoon but I don't want to bore you by going into a ton of details haha...
Here's the short version (I've asked about this on here before..)
1) It's an online course, geared towards women but great for anyone, who want to start their own skincare company from home.
2) It's much more affordable than most business classes, and it's geared 100% to skincare companies.
3) It teaches you the business side of things, but ALSO it teaches how HOW TO MAKE SKINCARE which is the big thing here because business is only half of it. If you're great at business but you can't make excellent skin care products then you're in trouble!
4) My girlfriend loves it, I just finished rubbing on some of homemade hand cream before typing this actually! It's organic, blah blah blah.. She's into that, so are her customers...
I've added a helpful review of Skincare Tycoon to the source section, it's the one my girlfriend usually shows to people who are curious.
Let me know if you have any questions, I've been hearing her rave about this course for months lol.
