Caution gorgeous skin ahead.
I've been using Estee Lauder Idealist Even Skintone illuminator for about a week after a tip from a friend at Saks (coincidentally my Mum has been using it too). I love it. The product claims include that over time skin will look noticeably clearer and brighter, vibrant and more even-toned. It is designed to be used under SPF moisturizer.
I'm only one week (claim is for improvement in 2 weeks) in and the results are great. They include 1) no breakouts 2) luminous skin without foundation 3) natural looking glow under foundation. Worth a try for sure, try it and tell me how you like it. Stay posh!
