The best way to make your makeup last in the water is to use products that are designed to take abuse! If I am going surfing with my husband, I try to look a little cuter, so I’ll put a thin rim of an ocean-y coloured 24/7 Glide on Eye Pencil pencil (like Deep End) all along my lash line. And it stays! If I went straight from work or a meeting and had a lot of shadow on, I could still go surfing! My Eyeshadow Primer Potion keeps it on, even in the water.
