Maybelline Instant Age Rewind Eraser Dark Circle Treatment Concealer. Great place to start, imo. Excellent consistency for the purpose. I recommend the pink shade along with one other a little closer to your natural skin tone. Let us know how you’re doing!

If you don’t want it to be too obvious you’re wearing makeup, maybe try using a tinted moisturizer instead?

The slight color should subtly cover the dark circles without being too obvious, and if you pick one that contains hyaluronic acid, that may also help reduce darkness.

For skincare, vitamin C serums and/or caffeine serums can both help improve the look of dark circles (though vitamin C may be irritating if you have sensitive skin or if you have a hard time keeping products from getting in your eyes). You may not see immediate results, but if you use those types of skincare ingredients regularly you should start to see improvement over the course of weeks

I’m having a lot of success lately treating my circles with a niacinamide eye cream twice a day, could be worth a try if you haven’t already

Nyx bare with me concealer serum, very hydrating and not full coverage so will look natural

For a bit more natural/lighter looking makeup I like the Becca under eye brightening corrector with the glossier stretch concealer. It’s like your skin but better. I usually just use the stretch concealer but if I’m doing a bit more makeup I’ll use both.
