Karine Joncas Hydra-Defense +C Serum is a daily illuminating treatment designed to target the first signs of aging and boost skin radiance. Formulated with 99% natural origin ingredients, its key component is Australian plum extract, a superfruit containing 100 times more Vitamin C than an orange. This potent serum delivers a smoothing effect, diminishes signs of fatigue, and provides an anti-pollution shield to protect against environmental stressors. The hypoallergenic, fragrance-free formula also features four types of hyaluronic acid for 24-hour hydration, leaving skin visibly radiant and plump. Suitable for all skin types, this versatile 4-in-1 serum can be applied day and night to the face, eye contour, neck, and décolleté.
