Dior Ultra Shock (851) Rouge Dior Ultra Rouge Lipstick ($37.00 for 0.11 oz.) is a medium-dark red with neutral-to-cool undertones paired with a lightly glossy, cream finish. It yielded opaque pigmentation in one, fluid stroke, and the color applied evenly and didn't get into my lip lines. The texture was lightweight, lightly creamy, and smooth with a more balm-like feel, as it didn't have the thickness/plushness of creamier lipstick formulas (yet still had the glide). The lipstick stayed on well for six hours, left a barely-there stain behind, and was lightly hydrating over time.

Rouge Dior Ultra Rouge is the first incredibly long-wearing lipstick with the comfort of a lip ink*: a true revolution in the history of lipstick. Ultra Rouge offers a lightweight, ultra-comfortable formula and all the colour of a high-pigmentation lipstick. The colours seem more saturated with a luminous, semi-matte finish** for incredible sensoriality and hydration.
