A highlighter is a cosmetic product that imparts a luminous glow to the skin, making it appear fresher and more rested, while also allowing for facial contouring.\nIt helps conceal fine lines, corrects skin texture, and gives it a healthy hue.\nWith the use of a highlighter, you can visually enlarge your eyes and make them more expressive, accentuate your brow line, reduce the appearance of your nose, and add volume to your lips.
