Yes, lip gloss can double as a highlighter. If you want to achieve a dewy and illuminated look, you can dab a small amount of clear lip gloss on the high points of your face, such as the cheekbones, brow bone, and bridge of the nose. Gently blend it with your fingertips for a subtle and natural glow. However, make sure to avoid using shimmery or colored lip gloss for this purpose.
