How to Start a Skin Care Business?

So I make homemade skin products (lotions, masks, scrubs), and my friends said I should open up a shop and sell them because they use them and they like it.

But I was wondering, how? What would I need to do to start selling my products? I know I would need them to be approved by the FDA (i think), but other than that, what else?

I am looking to start a comprehensive skin care regimen. I know I should wear daily sunscreen and also?

exfoliate daily with either alpha-hydroxy cream, or a facial scrub. I have been using a cream called Pentaxyl which is supposed to treat fine lines and wrinkles. But I am skeptical of anything that is not FDA-approved. Too many snake oil salesmen.
I heard of some prescription cream called Renova or Retin-A. What is the difference between these two? Is there anything else that i should know about how to take care of my skin?

How can I launch a homemade skin care line?

I have an idea for a skin care line, and I've heard of others doing very well after starting small. So, what steps do I take to actually do this?

Where are the recipes?
Also, what if I want to use specific active ingredients (e.g., alpha hydroxy or salicylic acid)? How do I get those? What government oversight will I be subject to? FDA? FTC?

Should I consult with a dermatologist and/or aesthetician first? If so, how do I find a good one, and what questions do I need to ask them?

Any tips for getting it into stores?
What else do I need to know?

I know I ask a lot, but I'm excited about my idea. I just don't have the know-how to make it happen. I appreciate any and all constructive advice.

Sarting a baby skin care line. What legal actions do I need to take?

What kind of legal steps and licensing do I need To Make and Sell Home Made Soaps?I am starting my own natural baby skin care line and am wondering if someone can help me out with what I need to do as far as licenses, Patents, Trademark?, etc to make sure I am doing everything legal and no one copies my brand. I will be making them at home myself. Does the FDA have any thing to do with this or the health department?
