The first signs of collagen loss are easy to spot. “You might notice your skin looking a little less firm or bouncy,” board-certified dermatologist Dr. Noah Gratch tells Vogue . “Fine lines show up more easily, you may see sagging around the jawline or under the eyes, and your skin might lose that smooth, full look. Basically, if your skin isn’t ‘snapping back’ like it used to, collagen loss could be the reason.”
