Can you use Vaseline on your face? Petrolatum is a powerful occlusive that helps lock in moisture and support the skin barrier. It can be especially helpful for dry, irritated skin and for sealing in your moisturizer at night. Apply a thin layer as the last step in your routine and focus on areas that need extra protection. Keep in mind, it can feel heavy and may not be ideal for everyone depending on your skin type and preferences. Have you tried it? Let me know your experience below. LTKBeauty
