One of the most common skincare questions we hear is whether a serum and a moisturizer are basically doing the same thing. In practice, they usually are not. At Bathhouse Trading Company, we think of serums as the support step and moisturizers as the finishing step.
A serum is often where you add lighter hydration or a more focused kind of support. Our Hyaluronic Acid Serum with Rose Water & Vitamin B5 is a good example. It layers in easily after cleansing and helps skin feel more comfortable before you move to the next step. Our Caffeine + Peptide Eye Serum is another example, but for a more targeted under-eye routine.
A moisturizer is usually what helps finish the routine and hold onto that comfort. In our catalog, that could mean our Solid Face Lotion, our Bakuchiol Facial Cream, or a richer option like our Night Shift Facial Oil when you want more of an evening finish.
If your routine feels incomplete, it is often because one of those jobs is missing. Cleanse, then serum, then moisturizer is still one of the most useful frameworks for building a face-care routine that feels coherent and easy to repeat.
