Yes, Kylie blush is designed to be long-lasting.
Kylie Cosmetics markets its blushes as having a long-lasting formula. The formula is described as being silky, smooth, and vibrant, designed to blend easily and "melt" onto the skin, providing a long-lasting color payoff. This suggests that the blush is formulated to adhere well to the skin and maintain its color throughout the day.
While individual experiences may vary depending on skin type, application technique, and environmental factors, the product is generally formulated with longevity in mind.
