Do you really need both a serum and a moisturizer?

Been seeing a lot of talk about how you should use a serum before moisturizing. Is this just marketing hype or is there something to it? I’ve been using just a moisturizer, but should I be adding a serum to the mix? What’s your skincare routine like?

If you’re curious about serums, it’s not just hype—they’re designed to deliver active ingredients deeper into your skin, while moisturizers lock in hydration. I switched to using both after learning how serums can target specific concerns like aging or scarring. For a simpler routine, some brands even offer combo products that do both in one step. Totally depends on your skin goals!
