Sure I can use shadow & concealer but they will settle into that hollow area & not draw the light in. Hollowness in the inner eye area can be caused by hormones, aging, low iron & fatigue. This was a problem I had encountered for years & felt there was no solution. I addressed my issues with Danyel Cosmetics & worked with them to create this product specifically designed for that area. This has been a customer favorite & sells out often. I’m happy to share it’s restocked. LTKBeauty LTKdayinmylife LTKstorytime
