Having had recent eyelid surgery to repair a vision problem, I was in need of a concealer to cover bruising as I went back to work. Being in my fifties, I finally decided to purchase Revlon's Age Defying Concealer with Botafirm (tm) / SPF 20. I opted for the 01 Neutralizer color after testing several colors available. I purchased this product at Ulta. I was absolutely blown away when applying the concealer. It covered so well using only the smallest amount, coworkers who knew I had surgery could not believe how great I looked. And for those who were unaware I had surgery, they never knew I had anything done. Now that the bruising is gone, I continue to use it daily as it's the best concealer for those under eye circles. It stays on until I remove it right before bed. It doesn't crease or look heavy or obvious. I was so happy with the concealer, I ended up purchasing the entire line of Revlon Age Defying Makeup and would highly recommend this product to anyone, no matter what age - everyone can use a little help looking and feeling beautiful.
Update On Jul 08, 2010: I still consider this to be the best makeup product for me and continue to use it daily. I've tried a few other products but nothing compares.
