COSRX Ultimate Nourishing Rice Overnight Spa Mask
The COSRX Ultimate Nourishing Rice Overnight Spa Mask is a popular K-beauty staple designed to brighten and hydrate the skin while you sleep. Formulated with over 68% Oryza Sativa (Rice) Extract, this versatile 3-in-1 product functions as a sleeping pack, a wash-off mask, or even a rich daily moisturizer. Rice extract is a powerhouse for evening out skin tone and providing intense nourishment, while Sunflower Seed Oil and Betaine work together to lock in moisture and soothe the complexion. The texture is creamy and luxurious, designed to leave the skin feeling supple, soft, and 'bouncy' by morning. While it offers significant benefits for those struggling with dullness or dehydration, its rich formulation includes several heavy emollients that provide a protective barrier. It is a go-to choice for users looking to achieve a radiant 'glass skin' glow, but its specific oil profile means it requires careful consideration for those with certain skin concerns.
Our Analysis
Our analysis flags the COSRX Ultimate Nourishing Rice Overnight Spa Mask as a high-risk product for those with acne-prone skin. While it contains beneficial rice extract, the formula includes Palm Oil and Palm Kernel Oil, both of which have a high comedogenic rating of 4/5. These ingredients are rich in saturated fats and Lauric Acid, which can create a heavy, pore-clogging film on the skin. Additionally, the presence of Cetearyl Alcohol, while typically a low-risk emollient, can increase the potential for congestion when formulated alongside certain other ingredients. For breakout-prone individuals, these ingredients may trigger comedones.
Skin Type Recommendations
This mask is best suited for individuals with very dry or dehydrated skin who do not experience regular breakouts. However, it is poorly suited for oily, combination, or acne-prone skin types. Due to the high comedogenic rating of its oil components, it is likely to cause clogged pores.
Flagged Ingredients
High saturated fat (Palmitic Acid) content creates a heavy, clogging film.
Similar to Coconut Oil; high in Lauric Acid and clogging.
Fatty alcohol emollient with low-moderate comedogenicity on its own. However, when combined with Ceteareth-20, the synergistic effect can significantly increase pore-clogging potential (combined rating of 4).
