This sheet mask comes from the "Reset" series, which includes the popular night serum "Immortelle Overnight Reset Serum." It is a single sheet priced at ¥2,420 (tax included).
In the season when you worry about skin damage from summer dryness, it is said to moisturize the skin in just 15 minutes of intensive care and lead to glowing skin as if you had slept deeply.
"Immortelle Overnight Reset Sheet Mask" for Glowing Skin in 15 Minutes
"Immortelle Overnight Reset Sheet Mask" was developed as the sheet mask of the "Immortelle Reset" series, which focuses on skin-sleep science. It is designed to charge moisture into the stratum corneum and comfortably cool down the skin.
According to L'OCCITANE en Provence's research, in a scoring evaluation comparing skin after eight hours of sleep with skin that had spent a day after eight hours of sleep and then used the sheet mask for 15 minutes, the mask was shown to lead to glowing skin as if the person had slept eight hours.
Main Features of the New Sheet Mask
Highly concentrated ingredients: Compared with one use of the Reset Serum, it contains about 20 times more of the immortelle ingredients (helichrysum italicum flower oil and helichrysum italicum extract) and gardenia extract (gardenia fruit extract). It is also said to contain about 28 times more of the spilanthes (Acmella oleracea) extract, which refines the skin's surface texture.
A material that clings to skin: It uses an ultra-thin 3D nano-structure mask that fits snugly against the skin. Made of an eco-friendly biocellulose derived from fermented coconut water, it is said to hold about 90 times its own weight in liquid.
Cooling effect: It is announced to cool down the skin by lowering its surface temperature by 4.6°C.
