Maybe your cosmetics are just too cold!

I've left my personal makeup kit in the car during the steamy summer months and frigid winter months. Linda at Pencil Me In Cosmetics advises against this. Here's her tip:
 
"Leaving your makeup on a cool countertop or in a warm car can temporarily change the consistency of your make up.  Most cosmetics are designed to be applied at room temperature. Application will be different if you try to apply your makeup outside of normal temperature range. It doesn’t mean that the cosmetic is poor quality, old or needs to be discarded; it means you need to allow the cosmetic to be brought back to a normal temperature before using.  For example, a cosmetic pencil left on a cold countertop may feel dry and scratchy when applying.  The application will be uncomfortable.  A simple solution is to warm up the pencil before applying.  You can roll the pencil between your hands to warm it up.  Draw a few small lines on the back of your hand to warm the core.  Once the core is warmed, the application should be silky smooth as usual.  If your pencil core is left is a hot steamy bathroom, the point may melt and smear during application. Allow the pencil to cool before you apply. Use of electric means to heat or cool your cosmetics is not recommended.  Fortunately the “pencil me in” (www.pencilmeincosmetics.com) eyeliner pencil cores are hard enough that the points won’t break during application yet soft enough for easy glide-on use."
