For clumpy eyelashes, use a lash comb to remove clumps. If you have problems under the eye such as dark circles, bags, uneven skin tones, wrinkled skin, etc .these problems will become more obvious if you apply mascara to the bottom lashes. Even if you do not use foundation or concealer a powder will give the skin a matte finished appearance. Powder makes things stay in place whether it be cream based products that move around or foundations, pencils or concealers. Makeup lasts longer with powder application.
Powder stops shine.
Don t over powder, it is healthy to have some sheen. Before applying powder make sure there are no lines or creases. Once you powder, it will stay put. If your face is very moist, blot first gently with a tissue, otherwise the powder will clump. Put a light layer of powder under the eyes before applying eyeshadow.
