COSRX Red Rice Inositol Pore Deep Cleanser 150ml

Features

COSRX Red Rice Inositol Pore Deep Cleanser is a multi-care, 3-in-1 solution designed to provide a deep cleansing routine that refines skin texture while managing pores and sebum. The cleanser features a unique, dense pink texture derived from Vitamin B12, which adheres to the skin to effectively absorb impurities and excess sebum. Formulated as a mild, low-pH cleanser, it is designed to maintain a healthy skin balance and is suitable for daily use, even on sensitive skin.

The product utilizes fermented red rice, which contains more than double the active ingredients of regular white rice, to provide powerful skincare benefits. Its versatile 3-in-1 formula allows it to function as a facial pack, a cleanser, and a skincare-boosting step, leaving the skin feeling moisturized and smooth without any tightness after washing.

Benefits

This cleanser helps remove impurities and excess sebum while refining skin texture. The formula is designed to boost skincare effects, ensuring that the skin remains hydrated and protected by a moisture barrier even after cleansing. It effectively clears away makeup residue, blackheads, and whiteheads while providing gentle exfoliation.

Usage instructions

For daily cleansing, take an appropriate amount, create a lather with water, and gently massage over the entire face before rinsing. To use as a wash-off pack, apply a generous layer to a dry face, avoiding the eye and lip areas. Leave on for 1–2 minutes, then gently roll with lukewarm water and rinse thoroughly. It is recommended to use the pack method 2–3 times per week based on individual skin conditions.
