Dd is like a milk bottle, and even palest shades are too orange. She has been using my Laura Mercier tinted foundation in the lightest shade, but still has a visible line. She wants really light coverage ...doesn't wear it every day, but for going out.
(she's nearly 17 btw in case anyone gets offended about a 12 year old wearing makeup!)
My whiter than white 15 yr old uses both Benefit's You Rebel tinted moisturiser in the palest shade or a fab MAC foundation also in a v pale shade.
Back before Xmas she was using god knows what and applying it with a trowel so I dragged her along to the MAC counter where we spent ages with the most wonderful chap who went through everything with her, showed her how to apply as well as how to make the most of her features. Now when she wears foundation she looks like a fresh faced teenager again!
My DD 14 loves Orgins Vitazing (llike sugarandspite said on page 1) it is brilliant - don't know how it does it, but it suits both our skins and I'm quite dark and she is very fair. Very natural looking.
