18 Stunning Models Spill Skincare Hacks You Actually Haven't Heard Yet

"I am such a huge skincare junkie, and I have a set routine that I do every day," said Giovanna Lopez, who modeled at Michael Costello's presentation. She noted that in addition to cleansing and applying serum every day, she's also a huge fan of using rosewater as a toner on her sensitive skin.

"I have rosacea flare-ups, so it's one thing that really helps to calm my skin and soothe my redness," she said. "Sometimes cotton balls can cause micro-exfoliation, so I tend to just pat the rosewater into my skin and let it absorb. If I feel like I do need a little bit of exfoliating, I'll apply it to a cotton ball and gently use it around my nose."
