I was quite nervous about using this as when I received it I saw on the bottle that it was made by Kryolan for Daniel Sandler. I work in entertainment, and the word Kryolan just makes me shiver as their products only leave those with the hardiest skins undamaged. I even had my dermatologist expressly tell me not to put the brand's wares on my skin. But I tried it in the colour 'Flush'... and the colour just 'sat' on my medium-deep skin tone. It was ashy. The brand's website guide recommended it for my skin tone, so I was a bit disappointed. But then I thought perhaps my foundation was too mattifying for the colour to meld properly. So I spritzed some Fix+ and it just came alive. It looked exactly as the name describes i.e. like my skin was flushed, which was exactly the type of pink hue that I was looking for as I find most pink blushes don't suit me. I think that it works very well, and even received compliments on the colour. It did not make my skin react, despite being made by Kryolan (which is a first ever for me!), in fact, it felt weightless. I think that it would work easiest with dewy type foundations, or if you tend to mix your foundation with oil, but Fix+ also does a great job at blending the colour seamlessly into the skin for a natural effect.
