From the Sephora website: 
What it is:
A gentle makeup remover suitable for all skin types.

What it is formulated to do:
Remove every trace of even the most resistant makeup with this soap-free formula. There’s no need for cotton pads—simply pump into the hands and rub onto dry skin. Add water to change the oil into smooth lotion. Effective yet gentle, this cleansing oil is suitable for sensitive skin and leaves the face soft and perfectly cleansed, without an oily film.

So first let me explain how to use this: Pump into hand. Apply to DRY skin. Rub in with fingers, especially in the heavy makeup areas like eyes. Apply water with hands which transforms product into a lotion. Wash clean.

When I first bought this I tried to use it like a regular oil…which totally didn’t work. This seriously needs the water to activate it because without it I was extremely disappointed & found it useless. That is what I get for thinking I know more than the back of the bottle though right? Note: You are never too good to read the darn bottle. Lesson learned.

From the reviews I’ve read on blogs & the Sephora website there are very mixed views. A lot of people had issues with this product leaving some kind of film on their face. While I personally didn’t experience this I am not shocked. Here is my tip: Use this as a makeup remover, not as your only cleanser. I appreciate the fact that this gets off my long wear foundations, waterproof makeup, & other things I absolutely hate removing in a snap without drying or irritating my skin. I then follow up with my normal cleansing routine, normally my Clarisonic & my nighttime cleanser. This doesn’t leave residue on my skin after it is rinsed away, doesn’t leave my combo/dry skin feeling any more dry or tight, & it is also formulated without parabens, sulfates, or synthetic dyes.

I feel like you have to make up your own mind about this product but using it my own way I am extremely happy with it. I barely need to use any of the oil to remove my entire face at night so the 6.4 fl oz will last me quite awhile. The $15 price tag had me wary but intrigued & now I think it is worth every penny. I highly recommend using less than you think & using the pump slowly since it can get a tad messy & you don’t want to waste it either. This is also a fraction of the price as many other high end cleansing oils & works the same & in some cases much better than other brands I have tried.

You can purchase the Sephora Supreme Cleansing Oil for $15 from the Sephora website & in Sephora stores.
