Oil v. serum: redundant to use both?

[anna7602]

I've been using Tarte Maracuja oil. My skin feels softer and the oil doesn't make me break out, but it's too soon to tell what the anti-aging benefits are. Can/should I layer a serum with it? And if so, which would I apply first?

If the oil serves as a moisturizer, I think it's ok to use serum as long as your skin is ok with both. I apply serum first and then moisturizer. I don't know if it's different when oil is involved though. It might be.

Not redundant. Serums are meant to be layered with other stuff. Serum goes first and after it has seeped in, oil.

I use a Vit. C serum, an oil, and then a moisturizer with spf every day.
