i-primer (eye primer) or eye shadow base comes in tinted or clear. Never apply eye cream, liquid foundation, or cream foundation on your eyelids. It can make your eye makeup bleed, smear and turn into a mess. It is very important to use primer or eye shadow base on your lids to keep your eye shadow in place. This way your gel/cream eyeliner won’t smear and last all day. It can also help prevent creasing and reduce appearance of fine line.
