Learn step-by-step how to use the PAT McGRATH LABS Skin Fetish Sublime Perfection Blurring Brush for concealer and setting powder, plus common mistakes to avoid.
Quick Answer
Use the Skin Fetish Sublime Perfection Blurring Brush with a tapping motion to blend concealer or press setting powder under the eyes for a soft-focus, airbrushed finish.
Why the Tapered Shape Matters for Under-Eye Application
The brush’s tapered design is not just aesthetic—it is engineered to fit the delicate under-eye curve. A flat or dense brush can push product into fine lines, whereas the narrow tip of this brush allows precise placement without disturbing the surrounding skin. This shape also helps you reach the inner corner of the eye where shadows often need extra coverage.
Common mistake: using a too-large brush that deposits product unevenly or drags the skin. The tapered head avoids this by letting you work in small, controlled sections.
Concealer vs. Setting Powder: One Brush for Two Jobs
This brush is versatile enough for both liquid concealer and loose or pressed setting powder. For concealer, use the brush to blend outward from the inner corner; for powder, use a gentle pressing motion to lock in coverage. The key difference is the amount of product—less is more for powder to avoid a cakey look.
Trade-off: If you prefer a very dense, buffing motion for powder, a fluffier brush might feel faster. The Blurring Brush excels at precision, not speed.
Step-by-Step Guide to Using the Blurring Brush
- Step 1: Prep the Under-Eye Area: Apply your usual eye cream or hydrating primer and let it absorb for 30 seconds. Then dot a small amount of liquid concealer along the under-eye hollow and inner corner. Wait for skincare to dry; otherwise, the brush will slip and push concealer into lines.
- Step 2: Blend Concealer with Tapping Motions: Using the tapered tip, gently tap (not swipe) the brush over the concealer, starting from the inner corner and moving outward. Use light, fast taps to diffuse the product without disturbing coverage. Swiping can lift concealer and create streaks. Tapping keeps the finish smooth.
- Step 3: Set with Powder (Optional but Recommended): Dip the brush into a loose or pressed setting powder, tap off excess, and press the powder onto the same under-eye area. Use a gentle pressing motion to lock the concealer in place. Too much powder leads to a dry, crepey look. Tap off thoroughly before pressing.
- Step 4: Clean the Brush Weekly: Rinse the bristles with lukewarm water, apply a mild brush cleanser, and reshape the tapered tip. Lay flat to dry. A clean brush prevents bacteria buildup and maintains the soft-focus effect. Don't soak the ferrule (metal part) – water can loosen the glue and shed bristles.
