This is an amazing serum for your face that helps to close up pores and refine/smooth the overall look and feel of your skin. It absorbs very quickly and a little goes a long way. Yes, it may leave your skin feeling slightly tacky for a minute or so, but that should go away.
Ursa Major calls this a 'face balm', but I would think of it more traditionally like a foundation serum or toner you would apply prior to putting on a moisturizer on top of this. Guys, don't forget this step! Yes, you could use this product on its own, but I don't think the intention is for this to replace your moisturizer; definitely add a moisturizer on top of this (oil-free/non-greasy recommended to blend well with this product) after giving the 'balm' a few minutes to soak in and set on your skin. Think of it in the same way you'd apply toner or serum prior to your full moisturizer in the morning.
As somebody will pretty oily skin and larger pores in the 't-zone' that get clogged easily, I really appreciate how light this serum is and how it closed up my pores and refined the overall look and feel of my skin without being oily or greasy. HUGE plus in my book! Highly recommend this product as part of your daily skincare routine!
