Hi, I am a photo retoucher and want to further my education to become more marketable in my area of interest & expertise, which is glamour & pageantry. In order to do so, I need to learn how to create those beautiful lips, skintones, eyeshadow, lashes, blush, etc. that I see on this website. What type of degree or courses should I be looking to take in order to learn this technique? I am not interested in creating characters, avatars, full bodies, animation, etc. just the make'up and skin. Would someone please give me some guidance?

I have attached a sample of the goal I am trying to achieve.

Thanks for any advice and help!
