I honestly can't say enough about this! I use it with other G.M. Collin products and honestly, it had made a HUGE difference in my skin! If I even feel a pimple trying to pop out, I dab a little bit of this on it and it starts to shrink. It smells earthy and kind of Tea Tree Oil and it tingles a little on contact which is really nice. It absorbs super quickly, and even though it has the word "oil" in the name, it is not oily at all. I have seen a dramatic difference in the hormonal adult acne on my jaw line. I will say that I only use this before bed, when my skin has a chance to regenerate after a long day of wearing makeup. My only beef with this product is the way that is dispensed. I wish that instead of shaking it out onto a cotton pad, it came with a pump or something I feel like less product would be wasted that way. I still give it 5 stars though. If you want something that is gentle, and not over-drying and effective, this is the product for you!
