What it is
Summer skin is best with a "preparation oil." Introducing a new cool type of the "moist and cool" touch pre-care oil W Treatment Oil, packed with the moisture your skin needs in summer. On days when you don't feel like layering multiple treatments, simply apply this cool and comfortable oil to your bare skin. It absorbs smoothly, providing a cooling sensation while softening and loosening the skin, addressing dryness and loss of firmness. Light and cool, achieve a fresh base makeup and radiant, moisturized skin even in the hot season. POINT 1 For soft, radiant skin with lasting moisture. It cools the skin while replenishing moisture, preparing it to easily absorb* subsequent moisturizing lotions and other products. Luxuriously formulated with RMK's unique blend of "moisturizing ingredients" and "emollient ingredients" rich in the blessings of plants. "Double moisturizing power" balances moisture and oil on the skin's surface, leading to a soft texture even in summer when skin is prone to dryness and loss of firmness due to external environmental factors such as air conditioning. The smooth, moisturizing feeling lasts throughout the day, making it perfect for summer skincare when you don't want to layer multiple products. Makeup application and adhesion are also improved, resulting in a glossy and beautiful finish. *Up to the stratum corneum POINT 2 RMK's uniquely developed formula A refreshing, moisturizing texture RMK's uniquely developed "cooling oil formula" is used. By mixing two layers, the oil that holds water-based components creates a fresh moisturizing and cooling sensation, resulting in a refreshing and light feel despite being an oil. It gives a cooling sensation to the skin after a bath or before applying makeup, making it perfect for the hot season. The light and easily absorbed texture is also recommended as a first oil for those who do not like oils. POINT 3 A summer floral citrus scent blended with multiple fragrances The floral citrus scent common to the W Treatment Oil series has been updated for summer. Based on citrus notes such as orange and grapefruit, with refreshing mint, floral notes such as rose and jasmine are blended in, and herbal accents are added. Enjoy a refreshing yet complex scent that is pleasant even in the hot season.
