1. Hydration Levels Impact Foundation Finish

A well-hydrated skin barrier ensures foundation glides on smoothly, creating an even, luminous finish. When your skin lacks moisture, foundation can cling to dry patches, accentuate flakiness, and settle unevenly. In contrast, hydrated skin appears plump and supple, allowing makeup to blend seamlessly.
Occlusives (like squalane) and humectants (such as hyaluronic acid) work together to lock in moisture and support barrier function. Research confirms that a healthy skin barrier is vital for water retention, directly influencing makeup performance. For expert hydration tips, visit the American Academy of Dermatology.
