I've been on a quest for a vitamin C serum that doesn't turn my sensitive skin into a red, irritated mess, and this Beauty of Joseon serum is the holy grail I never knew I needed. The first thing I noticed was the thoughtful opaque packaging – no light or air can sabotage this formula, which means every pump delivers fresh, active ingredients.

The gel-like texture is dreamy – it glides on like silk and absorbs instantly without any tackiness. I use two pumps every morning after toner, and it layers perfectly under my sunscreen and makeup. No pilling, no congestion, just a hydrated canvas that stays fresh all day.

What shocked me most? Zero irritation. Unlike other vitamin C products that left me stinging, this one uses 3-O-Ethyl Ascorbic Acid (a stable derivative) paired with soothing centella asiatica. After 4 weeks, my acne scars have faded from angry red to soft pink, and my skin has this lit-from-within glow that makes me skip highlighter.

Pro tip: Don't expect overnight miracles. Vitamin C works slowly but surely – by month three, even my stubborn sun spots had lightened. The pump bottle is genius too; I squeezed out every last drop with zero waste. If you're vitamin C-curious but scared of reactions, start here. It's like training wheels for radiant skin.
