It looks like I will buy any lipstick that has "Nude" in the name... although this isn't truly a lipstick.
This is the L'Oreal Colour Riche Balm. I purchased it in Nourishing Nude. It's the L'Oreal equivalent of the Revlon Colorburst Lip Butter (full post on those will follow soon).
I have read a few reviews that say these have a greasy, sunscreen texture, and I suppose they do. Revlon Lip Butters definitely have a heavier, thicker feel than these. The L'Oreal Balm has SPF 15, and I don't believe the Revlon Lip Butters have SPF.
They are available at Target for $5.99 and Ulta for $7.99 (although they are frequently Buy One, Get One 50% Off at Ulta).
