I have oily, acne prone skin with a fair number of blemishes. The main reason I bought this is because I read that rosehip oil is good for scars. Unfortunately this stuff broke me out and led to more scars. I have to say though, it is very moisturising and just 1 drop is enough for the entire face.
I ended up using the whole bottle because I tried testing it on different areas of my face, avoiding active acne and using it sparingly. The only real results I had were moisturised skin. It didn't do much else and I much prefer my vitamin c serum.
Positives: It is moisturizing, glides on easily, lasts a long time, and helps with scarring as well as lots of other skin problems. Negatives: It smells horrible!
