There are many rosehip oils out there, some of which are more costly and some of which are cheaper, but Trilogy's is good value for money. There has been a huge revival in the use of oils on the face, as opposed to creams, and there is a lot of evidence to back up its effectiveness. Oils are absorbed by the skin very well and many have a natural affinity. I have always used them at night, ever since I was in my teens and whilst they haven't turned me into Angelina Jolie (possibly just as well as I'm not overly keen on Brad's current moustache), my skin is much younger than it's age. Given that I spent a great deal of my teens and twenties cooking myself under the sun in vinegar and oil (makes you very brown but you smell like a chip factory), that's not bad. I also used oil based cleansers such as Burts Bees Orange Cleanser and then a hot flannel to take it off with. I always put the oil onto damp skin at night and that does make a difference: it sinks in faster and makes the skin softer. You need very little. You can also put a bit more on your face before you have a warm bath, pop a flannel over the top, and let the heat and moisture help it sink in.
This oil is also very good for softening scars, sunburn and the like. I also mix it with other oils to make an incredibly potent mixture which you pay a fortune for with certain companies. Other oils which combine very well with it are pomegranate, raspberry seed, nigella, passionflower and strawberry. If you want your skin to have a helping hand then do buy this.
