How can I conditionally change the thank you page URL/message based on user's answer?

Do you provide a survey form that can give a different link or answer at completion, depending on their answers?

I would like to ask customers questions about their skin type. When they are done answering, I would like to provide them a link to a page, or tell them what type of skin they have. 

Thanks.

You can conditionally show different THANK YOU PAGES to your customers or conditionally REDIRECT them to an external URL of your own after form submission.
