Beauty of Joseon Glow Deep Serum: Rice + Alpha Arbutin
Rice extract, the oldest brightening story in Korean skincare, paired with alpha arbutin, one of the better-tolerated modern tone ingredients. Arbutin is a slow, gentle worker on the look of dark marks and uneven tone; rice contributes a soft-focus, slightly milky finish that flatters skin immediately. The texture is thin and disappears fast, which is a large part of why this became the brand's most reached-for serum after the sunscreen.
What it is built around
Who it suits
Normal, dry and combination skin working on the appearance of post-blemish marks and general unevenness, and a reasonable first step for anyone who found vitamin C too irritating. Oily skin will like the finish. It is not a fast fix for stubborn melasma, and anyone dealing with that should be talking to a clinician rather than shopping — topical brighteners alone rarely settle it.
How to use it
Morning or night after toner, before moisturiser. Two to three drops over the whole face rather than spot-treating, since uneven tone is rarely as local as it looks. In the morning it belongs under sunscreen, and sunscreen is the part that actually decides whether any of this holds. Give it eight to twelve weeks before judging.

What is the difference between essence and serum?
In Korean skincare, essence is typically a thinner, hydration-focused layer that preps skin, while serum is more concentrated with targeted actives like vitamin C or niacinamide. Essence usually comes first; serum follows. The line between them blurs, and not every routine needs both.
What is the difference between essence, serum and ampoule?
Essence is the lightest and most hydration-focused, serum is more concentrated and targeted, and ampoule is the most concentrated of the three. The boundaries are marketing convention, not regulated definitions.
