L'Oreal Magic Perfecting Base (Face Primer). The box says 890 on the top, not sure if this comes in any different colors?
This retails at CVS and Walgreens for 12.99 normally, but sometimes goes on sale. I purchased it from CVS for $10.99. It has 0.5 fl oz in it, or 15 mL.
I have used this under my foundation on my t-zone, and my forehead was not oily, so I was happy. But I need to really test this on a day where I work and wear my foundation for 12+ hours.
So far my favorite use for this product, and the main reason I purchased it was to prime my undereyes before applying concealer. My undereyes have fine lines, especially when I smile, and I need to use a primer to prevent creasing. I'm trying out different products right now to see what works well for preventing or delaying the creasing with my new concealers.
This product is very good. I have tried out all my concealers, and using foundation as a concealer, and I have had much less creasing than without. When using my foundation, even a thicker layer, I don't have any creasing.
I also like the consistency. Its very creamy and soft, in fact, it feels like mousse, but so soft and silky. It dissolves into your skin, and feels very soft in the undereye area. It does not break me out either, which is important!!
I recommend this product if you are looking for a primer, but don't want to spend too much $$. I especially recommend this for undereyes!
