Neutrogena Stubborn Acne Ultra-Thin Blemish Patches are designed for acne-prone skin. These hydrocolloid patches help flatten the appearance of pimples with consistent use. These non-medicated triangle-shaped acne patches come in different sizes to suit small clusters or larger breakout zones. The facial patches turn white as they draw out fluid, so you can see them in action. Ultra-thin and flexible, they create a protective barrier that creates an optimal healing environment. The large acne patches are perfect for the cheeks, jawline, and body, while the smaller ones work well on nose, forehead, and chin. To use, apply to clean, dry skin and leave on for 8 hours or overnight. When ready, gently peel from one edge and stretch to release.
