Let's talk about Products. There are so many cosmetic products right now in the market so take your pick. Choosing one that would best suit your skin depending on the level of sensitivity, so take your time.
The most important tip I can give you is to blend, blend, blend! You don't want any visible lines one your eyes. One shouldn't be able to tell where the color begins and where it ends. It should be flawless and smooth.
