This is what they say about it:
Rimmel's Wake Me Up Instant Radiance Instantly lifts from fatigue and illuminates any part of your complexion. It is an ultra blendable cream formula enhanced with radiance pearls instantly sculpts cheeks or highlights browbones. Available in 2 ultra-sheer highlighting shades: radiant rose 002 and shimmering sand 004.
In real life the tube is tiny. It contains 14ml of product and retails for £4.99. But as soon as you put the tiniest blob on your hand, you realise on how very little you need. I felt the illuminator was extremely concentrated in product, and perhaps too much.
To be honest with you, I am not really sure how to work with this. They say that it's ultra sheer but have you seen how dark and pigmented it is? The second photo shows my attempt at blending the tiniest blob I had put on. Umm, I am not sure I can work with this. Could you?
