Lancome Blanc Scintillant is a slightly warm-toned, light white with a sparkle finish. It is a limited edition eyeshadow that retails for $26.00 and contains 0.045 oz.
Lancome Blanc Scintillant Petit Tresor Eyeshadow ($26.00 for 0.045 oz.) is a bright, sparkling white with subtle, warmer undertones and a sparkling, metallic finish. It had semi-sheer coverage applied dry and semi-opaque coverage applied damp. The consistency was soft, a little dry and looser in the pan, and this particularly shade was better used with a damp brush, as it applied more evenly. The color lasted for eight and a half hours both dry and damp, but this was nowhere near the 16-hours claimed.
The Petit Tresor formula is supposed to have a "delicate and creamy formula" that "does not crease" and can be used "dry or wet to increase color intensity," per Lancome's website. One additional claim, which was on several other retailers for this product, was that the formula is supposed to have 16-hour wear. The formula is comparable to ones like MAC Extra Dimension and NARS Dual-Intensity. It felt smooth in the pan, blended out easily on the skin, and tended to have richer pigmentation and a stronger, more metallic finish applied damp than when used dry. I think that the formula looks better in person than in just photos, as it has a very "lived-in" kind of finish--a little melted in, so there's an illusion of wetness but not creasing on the skin.
As long as you're not a stickler for wear time, I actually quite enjoyed these and felt like they created a beautiful, sparkling finish on the lid.
For eyes that sparkle, Lancome presents 4, ultra-pigmented shades in a new, limited edition delicate & creamy formula. Upon application, the fomula has a smoothing effect on the eyelid and does not crease.
