Helps reduce expression lines and chapped areas, leaving lips looking velvety. Enriched with nourishing oils, antioxidants and anti-aging ingredients, this Lip Filler improves texture and provides a volumizing effect on the lips. They look irresistibly fuller, with accentuated shape and shine. Due to its skin-safe pH level, this product is suitable for daily use. How to use In the morning: apply to clean mouth skin. You can then use your favorite lipstick or lip gloss. Reapply several times throughout the day as needed. At night: apply to clean mouth skin and leave on overnight as a hydrating lip mask. A temporary tingling sensation is expected.
