Yuja Niacin Brightening Sleeping Mask

Name: Some By Mi Yuja Niacin Brightening Sleeping Mask
Brand: Some By Mi

Korea ranking #24 maskUS stock

An overnight mask that works on dullness and uneven tone while you sleep, built on yuja — a vitamin-C-rich Korean citrus — alongside 5% niacinamide. Its texture is light and quick to absorb for a sleeping pack, so it suits anyone who wants brightening care without waking up under a heavy film.

More detail

Yuja (Citrus junos) extract forms the base of the formula, joined by 5% niacinamide, arbutin, and several vitamin C forms including ascorbic acid and ascorbyl glucoside — a stack aimed at dull, uneven tone and post-blemish marks. Panthenol, glycerin, and madecassoside keep it hydrating and calming, while jojoba oil supports the skin barrier. The texture is light and refreshing, absorbing quickly rather than sitting on the skin. Apply it as the last step of your evening routine, leave it on overnight, and rinse off in the morning. Because it combines several brightening actives with citrus-derived ingredients, sensitive skin should patch test first, and daily sunscreen will help the brightening results hold.
