This MARY & MAY Citrus Unshiu + Tremella Fuciformis Serum 30ml is formulated with 83.5% of Citrus Unshiu Fruit Extract and 9.7% of Tremella Fuciformis Extract to help revitalize tired and dull-looking skin. Citrus Unshiu is known for its brightening properties, while Tremella Fuciformis is a type of mushroom that has been used for centuries in traditional Chinese medicine for its moisturizing and anti-inflammatory benefits. Together, they work synergistically to improve skin elasticity, control sebum production, fade hyperpigmentation and promote a healthy, youthful glow. This Mary & May skincare serum suitable for all skin types and is perfect for those looking to achieve a more radiant, hydrated complexion. The lightweight and fast-absorbing formula penetrates deep into the skin to deliver long-lasting hydration, leaving your skin feeling soft, supple, and refreshed.
