Both hyaluronic acid and retinol can make excellent choices for any skincare routine aimed at supporting youthful-looking skin. Both of these anti-aging ingredients have unique benefits and uses. For example, you might apply a hyaluronic acid serum, like CeraVe Hydrating Hyaluronic Acid Serum, in the morning to help bind moisture to your skin’s surface—while smoothing it and providing up to 24 hours of hydration. Then, in the evening, you could opt for a retinol serum, such as CeraVe Resurfacing Retinol Serum, to help smooth your skin’s texture and brighten your skin’s appearance.
