Byredo 03 Definer Brush is a synthetic bristle brush and precision tool that delivers accurate contouring and seamless blending thanks to high quality cruelty free fibres. If uneven application or muddy edges frustrate you, this addition to professional makeup brushes delivers controlled placement and soft blendability for cream and powder.

• Precise contouring and sharp definition, reducing application time with densely packed synthetic fibres that pick up product evenly for exact placement.
• Seamless blending across cream and powder formulas, so looks stay natural rather than patchy or muddy, ideal as a precision contour brush.
• Balanced metal handle gives clear control and less wrist fatigue, letting longer sessions feel lighter and more accurate.
• Cruelty free and vegan design provides ethical confidence while matching the performance of natural hair brushes.
• Durable fibres hold shape through regular cleaning, maintaining performance and cutting replacement costs over time.
• Refined silver and black finish elevates professional kits and personal collections, offering a luxury appearance that competes with pricier alternatives.

Byredo engineered the 03 using advanced synthetic fibre technology to mimic natural hair structure, optimising pigment pickup and blendability (a detail that sets it apart from standard single purpose brushes). The metal handle is intentionally weighted for ergonomic balance, improving control for precise work. Vegan and cruelty free credentials mean ethical sourcing without compromising pro level performance for studio or everyday use.

Vegan, cruelty free and built to professional standards, this brush reflects Byredo's focus on quality and durability. Suitable for beginners and pros, it removes guesswork and simply performs — at least, that's what we've found.
