Lanluis insights
Healthy skin does not begin with fixing — it begins with protecting
UV exposure, pollution, and oxidative stress can gradually weaken the skin barrier and affect skin’s clarity, comfort, and resilience. That is why prevention matters: supporting skin earlier is often more effective than waiting to correct the signs later.
With antioxidants and barrier-supporting ingredients, Day Defence Serum is designed to help skin stay steadier through daily environmental stress:
・Niacinamide helps strengthen the skin barrier and build resilience over time.
・Vitamin C and Vitamin E help defend against oxidative stress caused by UV exposure and pollution.
・Resveratrol helps support skin as it faces the gradual visible effects of daily environmental damage.
・Prebiotics help support a healthier skin environment, keeping skin more balanced and comfortable through the day.
Together, these ingredients help skin stay clearer, calmer, and better protected — not just for the day ahead, but for the long term.
Ingredient insights
-
Resveratrol
A well-known antioxidant derived from grape skin and plant sources. Often referred to as a “longevity molecule,” resveratrol helps support skin against oxidative stress while caring for visible signs of photoageing, helping skin maintain a smoother, more resilient look over time.
-
Sodium Ascorbyl Phosphate (Vitamin C)
A stable form of Vitamin C that helps brighten uneven skin tone, support collagen, and defend skin against free-radical stress caused by daily UV exposure.
-
Inulin
A plant-derived prebiotic that helps support a healthier skin microbiome environment. It contributes to skin balance and barrier comfort, helping reduce dryness and sensitivity while keeping skin in a steadier, more comfortable state.
