I don't use liquid highlighters, and have never tried to get a glowy look. However, I received this product in a trial so I decided to give it a go.
I put a drop on under my liquid foundation and left my skin lovely, dewy and glowy. I did look slightly more oily than usual so I had to blot with powder to ensure I wasn't too shiny. I noticed throughout the day that the high points of my face did look shiny and highlighted.
This product really confused me. I had to look it up on the L'Oréal site to understand how to use it. I applied it blended with make up, on top, underneath, and with a base of moisture only. None of the application techniques worked for me, I didn't see as much of a shimmer as I expected and was left with a oily feeling on my skin.
I don't think I would use this again on my face as the oil slick, wet shimmer result was just gross. However I will try it mixed with moisturiser on my body for a golden dawn glow and see how that works.
Love the bottle, super classy, and the dropper is a great idea as a little goes a long way.
Tips: If it doesn't work on your face try it on your arms or legs with moisturiser instead!
