When i have dark circles under my eyes, i put on a thin layer and it totally conceals the purple color with its yellow undertones.
The less peachy tone of this concealer means that spots appear erased and I also use it for any red areas on my skin.
I found it a tad stiff and didn't glide the best so used a tapping motion.
Your ring finger has the least amount of pressure.
The translucence of this shade makes it suitable for fair to medium skin tone.
It would rub off in 2 hrs!
I have cystic acne and very oily skin, and also work 13 hour days - this means I need makeup that works as hard as I do.
Found that it also lasts a long time sadly had to recently throw one away because it had expired not cause I finshed it!
Then the erase pase under my eye.
