SOME BY MI Yuja Niacin Brightening Sleeping Mask | KoreanShopBD

Yuja, also known as yuzu, is a Korean citrus fruit exceptionally rich in vitamin C, at concentrations significantly higher than common citrus sources. It inhibits melanin production, protects against oxidative stress from pollution and UV exposure, and delivers a brightening effect that compounds with consistent overnight application. Niacinamide reinforces this by blocking melanin transfer to the skin surface, controlling sebum, and strengthening the barrier simultaneously. For skin in Bangladesh that deals with sun-induced hyperpigmentation, post-acne marks, and daily dullness from heat and pollution, this sleeping mask provides an effective and low-effort brightening treatment that works passively every night.
