On May 6, Sulwhasoo announced the launch of its 'Yeoyun Pack' Overnight Mask, a product designed to provide intensive overnight skincare.
The Sulwhasoo Yeoyun Pack delivers the core message of "firm skin density care experienced while you sleep." In particular, the mask helps reduce "sleep marks"-such as repeated pressure imprints and sleep wrinkles that occur during sleep-so that skin feels firmer and healthier the next morning.
Sulwhasoo focused on the fact that pressure and compression caused by sleeping posture overnight can leave long-term marks on the skin. To address this, the product features the Night Recharge Complex™, which boosts skin energy and strengthens the skin barrier to help tired skin recover quickly.
In addition, the mask contains adenosine, a functional ingredient for wrinkle improvement, and Sulwhasoo’s proprietary Jaumdan® complex to enhance the skin’s foundation. Squalane and panthenol provide powerful moisturization, while antioxidant ingredients such as vitamin C derivatives and vitamin E help promote clearer and more radiant skin.
The formula has been developed with a soft, creamy texture that is gently absorbed by the skin, leaving a fresh finish. Its non-sticky formula allows for a comfortable overnight use and is designed not to transfer to the pillow, maximizing convenience as a sleeping mask.
An Amorepacific representative said, “According to the customer satisfaction survey conducted after four weeks of use, we recorded 100% satisfaction for the statement ‘My skin feels more lively and recovered in the morning.’ In terms of reducing repeated pressure imprints and fine lines during sleep, satisfaction was over 96%. Satisfaction with the absorption, adherence, and scent of the product also exceeded 96%.”
