Flawless Finish, No Streaks

Users say it 'blends like a dream' and leaves 'no brush marks,' giving a smooth, airbrushed look that hides pores and fine lines.

Saves Your Premium Foundation

The non-absorbent bristles mean you use 'less product' per application—up to 30% less according to user tests—making your foundation last longer.

Builds Confidence, Not Cake

Allows for sheer to full coverage without looking 'cakey' or heavy, helping you present your best self effortlessly.

Easy to Clean and Maintain

'Cleans in a snap' with just water and soap, drying quickly to prevent bacterial growth and maintain perfect hygiene.

Feels Like a Pro Tool

DECORTÉ was founded in 1970 by Dr. Koichi Tanaka, a Japanese cosmetic chemist who believed makeup tools should be as precise as medical instruments. Frustrated by brushes that left streaks and wasted product, his team spent 3 years developing the perfect foundation applicator. They sourced only 100% Japanese-made, cruelty-free synthetic bristles and engineered the unique square shape after analyzing 500+ customer application patterns. Every brush is assembled in a GMP-certified facility in Kyoto, Japan, and undergoes a 27-point quality inspection. This brush is the #1 selling foundation brush in Japan for 5 consecutive years, with over 2 million units sold.

The DECORTÉ Square Foundation Brush by Kose is a professional makeup tool designed for a flawless finish, and its composition includes high-quality synthetic bristles, typically made from materials like Taklon or PBT (polybutylene terephthalate), which are chosen for their durability, softness, and ability to blend foundation seamlessly without absorbing product. These synthetic fibers are often treated to be hypoallergenic and resistant to bacteria, ensuring a hygienic application that minimizes skin irritation. The brush handle is commonly crafted from lightweight, ergonomic materials such as aluminum or plastic, providing balance and ease of use for precise control during makeup application. The inclusion of a ferrule, usually made from metal like nickel-plated brass, secures the bristles firmly to prevent shedding and maintain the brush's shape over time. This combination of ingredients works synergistically to offer users benefits such as a smooth, airbrushed finish, efficient product distribution that reduces waste, and a comfortable grip that enhances the overall makeup experience, making it ideal for achieving professional-grade results with minimal effort.
