e all have thin skin—at least on our necks, anyway. And even though the skin between our chin and our chest is more delicate than the rest of our body, we still tend to neglect it when it comes to our anti-aging routine. My favorite is the Knesko Nano Gold Repair Neck & Decollete Mask Combo ($45) because it contains all-natural ingredients like marine collagen, hyaluronic acid to hydrate and reduce inflammation, and niacinamide to firm and lift your neck.
