Lancôme’s latest foundation, Teint Visionnaire, is unusual in that it includes two products in one: a corrector (High Coverage Corrector, according to the official description) and the foundation proper (Flawless Perfecting Foundation). In the UK, there are 18 shades available, making it a bit confusing to find your match unless you have access to a counter.
With that in mind, I have swatched the four lightest shades in the range for comparison purposes: 005 Beige Ivoire (pretty neutral), 007 Beige Rosé (very pink-based), 010 Beige Porcelaine (yellow-based fair colour) and 01 Beige Albâtre (very yellow-based).
The pictures below were taken in three different lighting conditions: the first is a mix of indoor lighting and a bit of natural light from a skylight far up; the second is natural light on a rainy day; the third is direct “rainlight” (I refuse to call it sunlight with the weather as it is!). Swatches are in order as above, with the corrector on the left and the foundation on the right. My arm is about N10 for reference.
