I worked at Sephora and tbh that experience taught me that 9 times out of 10, internet ~beauty hacks~ are simply not meant for the average person. This includes contouring. It's ideal for experienced makeup artists who make careers out of doing celebrity makeup for the cameras, but other than that professional artists mock the general public for trying to adapt these stage tricks into their every day makeup.
Makeup is not supposed to look that heavy in real life. Hence why it's called 'instagram' or 'youtube' makeup (if you hear a professional using those terms, they're not trying to be nice) because it looks good ONLY on camera and usually with the help of filters.
Artists are so disappointed and exasperated with everyone wanting to use contour, baking, over-lined lips, overfilled eyebrows, bronzer and highlights used inappropriately etc.
Good makeup starts with great skin care and ENDS with great skincare. A pro trick is adding moisturizer ON TOP of light foundation or using skin care sprays or oils instead of heavy duty "setting" sprays. Fresh, dewy, with minimal product is where it's at.
