Okay so I'm suuuuper fair skinned and the dark circles under my eyes really stand out and so do the wrinkles I have there and I was wanting to know if there are any makeup products or technics to cover/fix this?
I already use a concealer but it pretty much melts after an hour
If your concealor melts off try using a primer. Primers help makeup last longer and make application easier and more flawless. If it still comes off you could also try putting a translucent powder over your concealor. The powder will also help your concealor last longer but it'll have a mattifying affect.
As for the dark circles concealor is really the only solution. You could also use a foundation for extra coverage but that would be a full face of makeup. When you apply your concealor make sure not to pull it or stretch it out across the underlids of your eyes, instead you should dab it into the skin in a downwards motion
Potato slices and lemons are natural bleacher. But lemons are acidic and might dry out your eyes. If you put a slice of potato or cucumber under your eyes for 15 minutes, it takes the dark circles away (at least for me). In terms of makeup, if you want your concealer to last longer, wash your face so that the concealer is on a clean surface. Also put on a moisturizer before concealer. Putting on a powder on top of concealer prevents it from looking oily and also makes it last longer :)
Do you put finishing powder over the concealer? If not then try that. Try using primer as well. Before the concealer. Let it dry before putting the concealer on though or else it might be a bit streaky.
