If you tend to go makeup-free during the warmer months, now is the perfect time to prep your lashes, ensuring they stun even without the addition of mascara. Meghan Markle knows all about this facial feature - in fact, she's even shared her go-to eyelash serum from RevitaLash, which you can now shop on Amazon. Previously, the Duchess of Sussex spoke with Allure on the essential products in her makeup bag, which includes RevitaLash's Advanced Eyelash Conditioner. "I swear they are as long as they could be," she said about her lashes after using the product.
