Martha Stewart, the 84-year-old lifestyle entrepreneur, has publicly endorsed Lancôme's Teint Idole Ultra Wear Foundation, highlighting its longevity and resilience. In a sponsored Instagram video, Stewart described the product as a "really good thing," emphasizing that the waterproof formula "can take the heat."

Stewart's endorsement details her use of the foundation across a range of activities, from baking to attending a cocktail party. The product is marketed as a long-wearing, breathable, and hydrating formula designed to last up to 24 hours.

She also expressed approval for Lancôme's newer Teint Idole Shape Stick. Stewart mentioned in an interview with InStyle that she uses the stick for added coverage where needed and in darker shades for subtle contouring along her cheekbones and jawline. She noted that the product allows for "quick complexion perfection without any fuss," blending seamlessly for a polished, natural appearance. The Shape Stick is versatile, capable of serving as a highlighter, blush, contour, or foundation depending on the shade chosen.

Other celebrities, including Kathy Hilton and Kris Jenner, have previously shared positive experiences with Lancôme products. Jenner remarked that the foundation "goes on so easily" and has a "silky" feel, while Angela Bassett has also featured the brand in promotional content.
