Well, I have full face tested each of the shades and walked outside with it, as well as mixed shades, used over mineral and chemical sunscreens, and mixed with my Giorgio Armani Fluid Sheers.
This foundation is a mixed bag.
First, the positives:
1. Beautiful, beautiful formulation. It feels like nothing at all.
2. It sets quickly and melds to the skin.
3. It gives naked skin a beautiful skin-sheen glow.
4. It lasts all day and does not disintergrate, or sweat off of oily skin.
5. It layers easily over serums and chemical sunscreens. There are no texture or shade shift issues.
Now, the bad:
1. If you do not have a (mostly) even-toned complexion, this will enhance the discoloration. This makes sense. It is a sheer-light coverage foundation that can be layered to deepen the veil of color, and reduce the peek through of your own undertones, but it is still a veil allowing discoloration to peek through…
2. Because this foundation has a sheer to light coverage, mineral sunscreens that leave you with a white cast, will peek through and muddle the “glow” aspect of this foundation. You will glow alright, but it will look a bit ashen because of the peek through. You need to use chemical sunscreens or truly transparent mineral sunscreens.
3. Despite allowing your own undertones to peek through, this foundation actually enhances the negatives of choosing a slightly off shade. I have many “not quite” shades, but they are masked mostly because the skin where it is applied is covered and looks uniform. When you use a shade with an off undertone, or overtone, it is ‘quietly’ noticeable with this foundation. What does that mean? At first you will think, wow some of the shades are so adaptable…then as it sets on your face you start to realize there is something kind of off with your skintone.
4. Using concealers with a different shade or texture will be obvious and not camouflaged. You may need to experiment with finding the right concealer to use with this product…or better yet, use no concealer at all, save for highlighter/concealer creamy pens.
5. Mixing two or more shades creates a muddled shade, not a super power shade.
6. Use a strong oil cleanser or makeup remover. This does not wash off easily. Preferable to double cleanse.
Overall, I still love the foundation, but I will not get a shade right now. I am between a BD40 and BD50. This is a great foundation for those who have relatively even-toned skin, or insignificant skin discoloration, but dull skin. It will be ideal to use a chemical sunscreen with this foundation. Make sure that the shade match you get is very good and works with your undertones. Since neither BD40 or BD50 match my undertone, there is a mild clash in the peek through that actually makes me look MORE uneven.
This foundation is great for those with a relatively clear and even skintone. But for those who need real coverage, this is not a good choice.
Hope this was helpful!
