Bronzer sticks are a must-have in a professional makeup artist's kit. They are versatile and easy to use, providing a natural, sun-kissed glow or a dramatic contour, depending on the application. Here are some of the best bronzer sticks that I recommend for professional makeup artists:

1. **NARS The Multiple Stick in Laguna**: This multi-purpose stick can be used on eyes, cheeks, lips, and body. Its creamy formula and sheer color make it ideal for creating a natural, all-over glow. The shade Laguna is a universally flattering brown with golden shimmer.

2. **Milk Makeup Matte Bronzer**: This bronzer stick is vegan and cruelty-free. It has a matte finish, perfect for contouring and adding depth to the face. The formula is creamy and blendable, making it easy to use.

3. **Fenty Beauty Match Stix Matte Skinstick in Mocha**: This bronzer stick is long-wearing, light as air, and has a soft matte finish. It's perfect for contouring and can also be used as a concealer or touch-up stick.

4. **Charlotte Tilbury Beach Stick in Ibiza**: This bronzer stick is perfect for creating a youthful, sun-kissed look. The formula is creamy and dewy, providing a natural glow to the skin.

5. **Bobbi Brown Skin Foundation Stick in Almond**: Although technically a foundation, this product can be used as a bronzer for contouring. The formula is weightless and blends seamlessly into the skin.

6. **Hourglass Vanish Flash Highlighting Stick in Bronze Flash**: This bronzer stick provides a seamless, lustrous highlight and makes the skin look radiant. The formula is weightless and easy to blend.

Remember, the key to a great bronzer application is to blend well and choose a shade that complements your skin tone. Always consider the product's ingredients to ensure it aligns with your skin's needs and sensitivities.
