They primarily target hydration and deep moisture, offer sun protection and color-correcting (tone-up) effects, and provide anti-aging or firming benefits.

Textures range from water-like essences and watery gels to lightweight, fast-absorbing serums. Finishes are typically non-sticky and dewy or sheer—often described as a glass-skin look—making them suitable for layering under makeup.

Many listings state suitability for all skin types; others specifically target dry or combination skin, and several explicitly note compatibility with sensitive skin.

They’re used as daily hydrating serums applied morning and night—often on damp skin—to boost moisture. They can act as lightweight makeup bases or primers, and some mist formulas can double as toner, hydrating serum, or a makeup-setting spray.
