I've come to the conclusion I really don't have a need for rosehip oil, but I'm not going to ding a product just because I don't see much personal value in it.
What I noticed was that Dr Song oil doesn't smell bad (I've tried some stinky rosehip oils), it's definitely moisturizing, and my skin doesn't react badly, so no irritation, which is nice. If you're looking specifically for rosehip, of the few I've tried, Dr. Song would be my preference based on my skin after using it and the smell.
This oil is really potent. Basically, a tiny amount goes a long way. I had a hard time not applying too much because even a drop for me is more than plenty. If your skin is quite dry, you might find this really moisturizing and great soothing legs after shaving.
So, overall, it's a good oil. I may not use it, but my husband probably will and if you're looking for a good rose hip oil, this one seems well produced without the stink.
