I definitely agree with what others have said about paler shades. Although I call myself an NC15 I am really a bit lighter than that. I would also like a pump to come on all foundations in the world!
Most of all I would like to see more foundations at all coverage levels for truly sensitive skin, to include people with rosacea skin....they would be:
oil-free (that means zero oils - no essential oils, castor oil, or even "natural oils" - per Jane Iredale - such as jojoba)
fragrance-free (that includes citronellol, sandalwood, and any other esoteric or natural excuse for "parfum")
no chemical sunscreen agents (zinc and titanium would be fine, as would leaving sunscreen/sunblock out altogether)
no propylene or pentylene glycol (butylene glycol would be fine), SD or denatured alcohol, bismuth, aloe, arnica, anything citrus, natural extracts no one has heard of before that are destined to change your life (I'm talking to you Chantecaille!), kaolin, peptides, fruit acids or extracts or anything else designed to lift, tighten or otherwise physically help wrinkles or build collagen, triethanolamine or BHT
Face Atelier has the ingredients right, IMO, but their shades do not run pale enough (and probably not dark enough either) and they're very inaccessible. Their plus and minus shades are nice, but I found porcelain (the lightest foundation shade) so dark for me that I would have needed to buy full sizes of both it and zero minus for over $80, then play around with mixing, and then hope the resulting undertone would look okay.
