To cut to the chase: Estee Lauder Invisible is an awesome formula that's impressed me more than any other in a long time -- a lightweight, applies-perfectly-with-fingers-and-without-a-mirror milk that seems to give a natural satin finish on almost all skintypes, and good medium+ coverage while hardly adding any texture to the skin. All this without any of the drying, irritating alcohol with which the likes of Chanel Vitalumiere Aqua and most popular Japanese milk sunscreens are filled.
Lancôme Teint Idole Ultra 24Hour...not so much. Full of alcohol yet dragging upon application and setting to an unflattering flat matte finish, while offering only marginally more coverage than Invisible, it actually seems to me to be a barely evolved version of Estee Lauder's most dated formula, DoubleWear. It does however beat Invisible in offering a much wider shade range -- I've swatched the palest shades from both formulas, with some other foundations for context.
Make Up For Ever Mat Velvet+ 15
Lancôme Teint Miracle 005
Teint Idole Ultra 24 Hour 005 (007 is a little darker and quite a bit pinker)
Estee Lauder Invisible 1N1
Estee Lauder Invisible 1CN1
Laura Mercier Silk Creme Soft Ivory
Suqqu Frame Fix Cream 101
I wondered before sampling why Invisible didn't have a 1W(arm)1 shade as other Estee Lauder foundations do... and now I know it's because both the 1N(neutral)1 and 1C(ool)N(eutral)1 shades run warm yellow. If you wear another EL foundation, I'd recommend 'sizing cool' in this one -- if you wear W, try N. If you wear N, try CN. If you wear C... best of luck but don't get your hopes up.
For your amusement, here is me testing an extremely light layer of Invisible 1CN1, with further washing-out by my camera:
Seriously, Lauder Corp, pale shades we can haz?
