Face oils and serums often end up in the same "upgrade your routine" conversation, but they're doing very different jobs. Using one when you need the other is a common mistake, and using them in the wrong order makes both of them less effective. Here's how to think about it.
Serums work deep. A serum is typically water-based with a small molecular size, which means it's designed to carry active ingredients - peptides, vitamin C, hyaluronic acid, niacinamide - into the skin where they can actually do something. The whole point of a serum is delivery. You're getting a concentrated dose of something specific to your skin concern, and the formula is engineered to get it where it needs to go.
Face oils work at the surface. Oils are lipid-based, which means they sit above the skin and work by supporting your barrier rather than penetrating it. They seal in moisture, smooth texture, and give skin that healthy glow that's really just well-hydrated, well-protected skin doing its thing. A good face oil doesn't replace hydration - it locks in the hydration that's already there.
So do you need both? Not necessarily, but they complement each other well. The order matters: serum first, oil last. Think of it this way - you want the actives in contact with your skin before anything occlusive goes on top. Once the oil is on, it's harder for water-based products to absorb through it. Serum first, oil to seal.
One ingredient worth knowing about if you're new to face oils: squalane. It's naturally occurring in human sebum, which means your skin already recognizes it and knows what to do with it. It's lightweight, non-comedogenic, and works on essentially every skin type including oily. Our Squalane & Agave Facial Oil uses it as the base for exactly that reason - it gives you the barrier support of a face oil without the heavy, greasy feel that turns people off oils in the first place.
If you want the active ingredient work, that's where a serum comes in. Our Rejuvenating Serum and Copper Peptide Serum are where the targeted skin concerns get addressed. Use one of those underneath, finish with the oil, and you've got a routine that's actually doing something.
