Benefits
136% improvement in surface hydration after one use - Green Tea-HA and multi-weight hyaluronic acid flood the skin with refreshing moisture instantly, with deep hydration improving by 23.27% from the very first application.
Proven barrier repair on irritated skin - clinically shown to reduce moisture loss by 62-63% on skin compromised by chemical or physical irritation, making it the right recovery step after exfoliants, peels, or environmental stress.
Lightweight enough for reactive skin to tolerate daily - watery, non-sticky texture absorbs in seconds without heaviness, confirmed hypoallergenic across a five-week clinical study on 52 subjects.
Antioxidant protection built in - Green Tea-HA delivers antioxidant benefit alongside hydration, protecting skin from the environmental stressors that trigger sensitivity in the first place.
Hero Ingredients
Green Tea-HA
What it does: Beauty of Joseon's exclusive ingredient - Green Tea water used as the formula base rather than plain water, delivering antioxidant, soothing, and hydrating benefits from the first ingredient down. Combined with hyaluronic acid, it provides 136.2% improvement in surface hydration and 18.99-30.19% improvement in soothing effects on irritated skin in clinical testing.
Why we chose it: Using Green Tea water as the base rather than adding it as a supporting extract is a formulation decision that shows genuine commitment to the ingredient - it's what makes this serum distinct from basic hydrating alternatives.
Panthenol
What it does: Provitamin B5 at a meaningful concentration - forms a moisture veil over the skin that reduces transepidermal water loss and conditions the barrier so hydration from the Green Tea-HA complex stays in the skin rather than evaporating. Clinical results showed 62-63% improvement in moisture loss on compromised skin after consistent use.
Why we chose it: Panthenol is the barrier-locking mechanism that gives this serum its repair credentials - without it, the hydration would be temporary rather than cumulative.
Artemisia Capillaris Extract - Mugwort
What it does: A traditional Korean botanical with well-documented calming and anti-inflammatory properties, working alongside Green Tea to reduce visible redness and support skin recovery. Particularly effective for skin experiencing reactivity from active ingredient use or environmental exposure.
Why we chose it: Mugwort is one of the most credible calming botanicals in K-beauty formulation - its presence here alongside Green Tea and Panthenol creates a genuinely layered soothing approach rather than a single-ingredient claim.
Studio Pick
The Beauty of Joseon Calming Serum is our go-to recommendation for skin that's struggling - reactive, over-exfoliated, or just in need of a reset. The Green Tea-HA base is a genuinely thoughtful formulation decision that goes beyond standard botanical marketing, and the clinical data on compromised skin is the kind of evidence we require before calling something a barrier repair product. Alcohol-free, fragrance-free, and vegan, it's one of the most universally appropriate serums in our catalogue - and one of the easiest to recommend with confidence.

Frequently Asked
Is this suitable for acne-prone skin as well as sensitive skin?
Yes - it's clinically confirmed non-comedogenic after a four-week study on acne-prone subjects and hypoallergenic after a five-week study on sensitive skin. The alcohol-free, fragrance-free formula contains no known acne-triggering ingredients, and the calming Green Tea and Mugwort base actively helps settle the redness and inflammation associated with breakouts. It works well as a daily serum for skin that struggles with both sensitivity and congestion.
Where does this sit in my routine and can I layer it with actives?
Apply after cleansing and toning, before moisturizer. On evenings when you use exfoliating acids or retinol, this serum is an ideal follow-up step - clinical testing showed 62-63% improvement in moisture loss on chemically irritated skin, making it a reliable buffer between actives and your moisturizer. It's also gentle enough to use on the same evening as most actives without concern.
What is Green Tea-HA and why does it matter?
Green Tea-HA is Beauty of Joseon's proprietary ingredient - Green Tea leaf water used as the formula's water base rather than plain water, with hyaluronic acid incorporated into it. Using Green Tea water as the base means every drop of the formula carries antioxidant and calming benefit from the ground up, rather than adding Green Tea extract as a minor supporting ingredient at the bottom of the list. Combined with HA, it delivers hydration and environmental protection simultaneously.
My skin is very dry - how much should I apply?
Apply a small amount first and allow 60 seconds for full absorption before adding more. Layering is more effective than applying a large amount at once - two or three thin layers absorbs more completely than one heavy application. Applying on slightly damp skin (just after toning) significantly improves the hydration effect for dry skin types. Follow immediately with a rich moisturizer to prevent moisture loss.
How long will 30ml last?
Used twice daily with 3-4 drops per application, 30ml typically lasts 6-8 weeks. The dropper format makes it easy to dispense consistently without waste. For maximum hygiene, avoid letting the dropper make direct contact with your skin or palms - decant into hands before applying. Store at room temperature away from direct sunlight.
