I bought this foundation recently and have word in three times so far. It can be tricky to find - Sephora does not stock it, even though they have the stick and powder foundations from the Sun Protection line, and Macy's (at least the one I visited in Boston) doesn't carry all the shades.
I have been looking for a foundation with a high SPF & UVA protection that wears all day, matches my skin tone, and doesn't break me out. So far, so good.
The sun protection of this foundation is excellent. Because it can go on a little dry, I have been applying a separate sunscreen, on dry areas on my face beforehand - you could also use a moisturizer or a primer. If you have dry skin you should prep, but this foundation doesn't go on excessively dry.
I was concerned about the color match after reading some of the other reviews. I bough SP-10, the lightest shade. I have fair skin (MUFE 115) with some acne scarring. SP-10 matches acceptably. It is probably a touch too yellow, especially by the end of the day when it has oxidized, but it's really not bad. The coverage is really nice - it doesn't completely obscure your skin, and gives a very attractive soft matte finish. It sets rather quickly as you apply it, so it's best to go section by section. Even though the finish is matte, it seemed to lessen the appearance of fine lines - definitely a plus.
As for break outs, it may be too soon to say, but I've had no problems as yet. The foundation feels light and "dry" to wear, not clammy, greasy or tight like some of the foundations that have broken me out in the past (I'm looking at you, L'Oreal Infallible and Almay Line Smoothing MU).
Overall I am very happy with this foundation (HG? we'll see...). It's a challenge to find a foundation with sunscreen that doesn't ruin acne-prone skin; this one looks like a winner. A final note about the price - $32 is not cheap, but it is within the range for this quality, and in the long term it will be worth it for the greater sun protection.
