· Eye Brightening: One of the most common uses is to brighten the eye area to reduce the appearance of dark circles and eye bags. Apply the highlighter to the bags and under-eye area under the eyes and tap gently with your fingertips or beauty sponge to blend evenly.

· Brighten T-Zone: If you want to highlight T-zone areas such as your forehead, bridge of nose, and chin, you can apply a highlighter pen to these areas. This can help brighten the center of the face and make it look more dimensional.

· Accentuate the chin: To emphasize the contours of the chin, apply highlighter to the underside of the chin and along the lower edge of the chin. This helps make the jaw line more defined.

· Brighten lips: If you want your lips to be fuller and three-dimensional, you can apply a highlighter pen on the top of your lips. This can help lips look fuller.

· Conceal blemishes: Highlighter pens can also be used to hide blemishes on the face, such as acne scars, hyperpigmentation, or redness. Dab the highlighter onto blemished areas and blend evenly to lighten their appearance.
