As someone with very prominent genetic dark circles that never really covers them up because they look ashy with concealer and I’m too lazy to colour correct:

• what is the point of concealing them? I think they kind of make me look sick, but if people are offended by that, that’s their problem
• is a free smoky eye (you can turn it into a smoky eye somehow apparently)
• could be a good idea to determine if they’re genetic or something else like a vitamin deficiency. Unfortunately genetic ones you can’t really get rid of or so I’ve heard?
• get a concealer that matches your skin tone as lighter ones, which are commonly used in the beauty community, can look a bit unnatural
• colour correct with a salmon, peach, or red colour corrector depending on the colour of your circles. Vary the lightness (I know this is the wrong art word) of the colour according to your skin tone.
