HARUHARU WONDER Black Rice Night Knight Retinol Serum 20ml

HARUHARU WONDER Black Rice Night Knight Retinol Serum 20ml is a targeted anti-aging night serum under the HARUHARU WONDER brand, with two core selling points: "fermented black rice extract + stabilized retinol" and "night-focused repair".

The "Black Rice" in the name refers to its core natural ingredient—fermented black rice extract, which is rich in antioxidants, amino acids, and vitamins. It soothes the skin, enhances moisture retention, and reduces irritation caused by retinol while brightening the complexion. The "Retinol" is the key anti-aging ingredient: the product uses stabilized retinol (to maintain long-term activity) with a moderate concentration, which can promote collagen synthesis, smooth fine lines, improve skin elasticity, and accelerate keratin renewal to refine pores and texture.

The "Night Knight" positioning emphasizes its night-specific repair function—retinol works best in a dark environment (avoiding UV-induced degradation), and the serum’s formula helps the skin repair aging damage during sleep. The 20ml capacity is suitable for 1-2 months of night use (when building tolerance, the dosage is lower). The texture is a lightweight, fluid emulsion that absorbs quickly without clogging pores or causing greasiness. It is positioned as a "mild, effective entry-level anti-aging serum", suitable for users who want to start anti-aging care without irritating the skin.
