Face Brushes / The Concealer Brush FAQs

Get the most from your product with answers to frequently asked questions about application, ingredients, and care.

How do you clean the Kjaer Weis brushes?

Use a natural brush cleanser or a gentle natural soap or shampoo, and cleanse once a week to prevent bacteria buildup and keep the bristles performing at their best. Rinse thoroughly, then lay the brushes flat on a cloth to dry overnight. Make sure water does not get into the ferrule during cleaning.

What are the Kjaer Weis brushes made of?

All of our brushes are made from hypoallergenic synthetic fibers, dermatologically tested and gentle enough for sensitive skin, including those prone to irritation or redness. The synthetic fibers are specifically designed to pick up just the right amount of product for a precise, even application every time. The full range is vegan and never tested on animals.

How do you know which brush to use with which product?

As a general rule, denser bristles work best with liquid and cream formulas — the Buffer Glow Brush and Buffer Concealer Brush are both designed for this. The Concealer Brush is suited to more targeted, concentrated application. The Powder Brush, with its large, fluffy angled head, is designed for powder products across a wider area. The Soft Eye Brush is the go-to for eye shadow, applying color in smooth, blendable sweeps across the lid.

Why does Kjaer Weis use synthetic fibers instead of natural bristles?

Synthetic fibers allow for precise control over how much product the brush picks up and deposits, which means more consistent, even application. They are also hypoallergenic, easier to clean, and more durable over time. And unlike natural bristle brushes, which are made from animal hair, our synthetic brushes are fully vegan without any compromise on performance.
