After hearing about Chanel discontinuing their Pro Lumiere foundation, I finally decided to cave in and buy it. I am currently a MAC NC25 in SFF. I tried both 30 and 40, but found that 30 was slightly darker than NC25. The difference between 30 and 40 is about half a shade, so technically I could get away with either. 40 would probably be an NC30 - 35 equivalent and great as my summer shade. That being said, I did find that this foundation is a little heavier and probably best for spring/fall and winter. So I went ahead and chose 30 cendre.
I had also heard amazing things about the Teint Innocence foundation (liquid) and that it was unfortunately discontinued as well. However, the counter I went to, still had them! Woohooo! And with a $20 discount and vouchers from work, I simply had to try it as well. I chose 40 in the Teint Innocence as it felt lighter and suitable for summer. I will probably use this more in summer or even mix the 2 throughout the year.
I will write an in-depth review with swatches once I have tested the foundations enough.
Have you tried Chanel foundations?
