Choosing the Right Facial Brush for Your Skin Type
Best Sonic Facial Brush
The best sonic facial brush works well for normal to combination skin. It’s perfect for quick, effective cleansing without intense exfoliation. Look for silicone bristles and multiple vibration modes.
Ultrasonic Face Brush
An ultrasonic face brush is ideal if you’re targeting blackheads, acne, or early signs of aging. Its micro-vibrations reach deeper than sonic tools—making it more effective for collagen stimulation and serious skin renewal.
