Most often used to slough away the surface layer of the skin, body scrub can help create a smoother surface and stimulate blood flow. This creates a deeper color in the skin, giving it a healthy-looking, vibrant glow. Certain brands of body scrub may be usable for both the face and other areas of the body; however, other brands are exclusively made for the face, and contain gentler ingredients which are less likely to cause skin irritation.
