When your skin is angry, red, or just completely over it — this is the serum to reach for. The Beauty of Joseon Calming Serum is a lightweight, fast-absorbing formula built around three heavy hitters for sensitive and stressed skin: 50% Green Tea Leaf Water, 30% Mugwort Extract, and 5% Panthenol.

Here's what each one brings: Green Tea (Camellia Sinensis) is one of the most antioxidant-rich ingredients in skincare — its key compound EGCG actively soothes UV-damaged skin, neutralises free radicals, and helps prevent the kind of environmental stress that accelerates ageing. Mugwort has been used in traditional Korean medicine for centuries and is now recognised as one of the most effective plant-based calming ingredients available, providing deep moisture while reducing inflammation. Panthenol (Pro-Vitamin B5) at 5% creates a moisture shield on the skin's surface, locks in hydration, and supports barrier repair — the thing your skin needs most when it's irritated or compromised.

The formula has a naturally pale green tint from the mugwort, a light watery texture, and zero fragrance. It absorbs instantly and works beautifully as a pre-moisturiser calming step, particularly on days when your skin has been exposed to sun, harsh weather, or active ingredients like retinol or acids.

Sul Skin note: One of the most genuinely soothing serums in the Beauty of Joseon range — the green tea and mugwort combo is particularly good for UV-stressed Australian skin.
