I have been on Dan's regimen and products since Jan 2010 - and have clear skin. I wanted a light foundation to help even out my skin tone from acne scars and melasma. I hunted down this foundation (not available in stores, it's been discontinued - CoverGirl makes a clean, but it's not specified specifically for "sensitive" skin anymore like the old bottles used to) - on the web to try. I got color classic ivory 210 - and found it was a perfect match for my skin tone (more yellow, not pink). I was afraid it would be too light - but it blended well, and I don't need to use a lot since my coverage is light and only for skin spots/uneven skin tone. To me, this is a thick foundation, but that's because I usually only wear powder, no foundation. But it did work wonders for evening out my skin tone without being dry. I will update if this breaks me out - but now wearing it all day for 2 days - i've had no problems, no itchiness. Nothing. I wear Dan's BP lotion on my skin after I shower, and apply some Olay sensitive skin moisturizer to my dry areas - then I let my skin sit for about 1-2 hours. I then apply this foundation with a beauty blender sponge - and I'm good to go. I usually dust a little Neutrogena Shine Free powder over to set it - but that's only if you get super shiny skin. I do. I found this foundation helped take the redness away on my skin from BP that I always tend to have - and it's been great. I will note that the bottle I ordered is the ORIGINAL Clean sensitive skin foundation that came out with the lime green sticker and lime green bottle cap. Just to make sure - there are some others that say "Clean" but aren't for sensitive skin. This was one of the original sensitive skin foundations they came out with - and it's water based. It does contain TALC - which normally breaks me out - but I will update if this does become an issue. So far, nothing. The foundation is so light - it feels like you have nothing on. EDIT: after a week of use (every single day for hours while at work) - I have to come back on here and give praise to this discontinued product. I have never, ever been a foundation wearer. Ever. The thought of putting something on my skin like that just made me want to ITCH. I have very sensitive skin, have had acne since my twenties - but with my skin under control, I have some light discoloration that I'd like to even out - and THIS STUFF is PERFECT. It's water-based, very light - does a good coverage (I think it's buildable) and it DOES NOT BREAK ME OUT. AT ALL. I use this over my BP lotion after it has dried and my moisturizer about 1-2 hours later - and I can wear it all day. I pat some shine free powder over it - and am good to go. If you have very acne-prone skin, please hunt your color down in this sensitive skin (green top, green sticker Cover Girl bottle) and try it. Hands down, the best foundation I've ever tried. It even has talc, but that does not seem to bother my skin at all.
