Erika demonstrates the versatility of the Hot Fluff Matte Multistick in Gingerbread by Jason Wu Beauty in her video review. She starts by applying it to her lips, creating a blotted, natural look. She then uses the product on her cheekbones, blending it with her fingers for a soft, flushed effect. Erika also applies the multistick to her eyes, concentrating on the outer corners for a blush-like appearance. She completes the look with eyeliner. Overall, the product seems to be easy to use and provides a natural, monochromatic look. However, it's worth noting that Erika mentions having eczema on her inner eyelids, which she tries to avoid by focusing on the outer corners. This could potentially be a drawback for individuals with sensitive skin.
