"I use Circle/Delete #1 as my every-day concealer to hide dark circles and uneven skin tone (redness), but now I have added Active Light 1 - Light Yellow as C/D's perfect partner, to highlight areas on my face that I want to enhance, not conceal. That is, I don't think Active Light is the best concealer, but it is a fantastic highlighter. I draw a line across the tops of my cheekbones and blend upward around the outer corner of my eyes; I also draw a thin line down the bridge of my nose, over each eyebrow, put a dab in the little divot over my upper lip, and in the crease at the top of my chin, just below my bottom lip ... and then I blend well (use warm, clean fingers to pat-press-roll the product into my skin, rather than rub). I apply Circle/Delete under Jane Iredale mineral foundation and Active Light over top; then I set with translucent (often high-definition) powder, spray with POMMIST, and my skin looks flawless, especially in photographs. Active Light 1 - Light Yellow is the same color as the light side of Circle Delete #1. It would suit people with fair coloring (warm or cool), and it is comparable to MAC NC15 Studio Sculpt Concealer, but I prefer Jane Iredale concealers because they do not turn chalky and dry or settle into fine lines or pores."
