The star ingredient in this oil is Black Gram (Vigna Mungo) which is supposed to firm and tone skin to reduce the look of wrinkles. I don't know if it is the magic ingredient that Iyura say it is but I can say I was pleasantly surprised by this oil - the texture is lovely and light and I found my skin soft and with a little more bounce to it when I woke up in the morning.
You can purchase a box of mini oils to test before you splash out on a big bottle, the oils are expensive but I think worth the price. They last a long time.
