Mugwort

Also known as: Artemisia, ssuk

What Is Mugwort?

Mugwort refers to several species of Artemisia, a family of aromatic herbs. In Korea, mugwort, called ssuk, has long been used in cooking, teas and traditional bathing rituals. Korean skincare typically uses Artemisia princeps or similar species, often grown in specific regions known for the plant, and may present it as an extract, a leaf water or a fermented form.

Mugwort contains a mix of plant compounds, including flavonoids and other antioxidants, that are associated with calming and protective effects on the skin. In practice, it is used for skin that looks red, feels warm, or is reacting to stress, weather or breakouts. Some essences replace much of the water in the formula with mugwort extract, giving a light, watery texture that suits layering.

It sits alongside centella asiatica and green tea as one of the most traditional calming botanicals in Korean skincare.

Mugwort Benefits for Skin

• Helps soothe the look of redness and irritation.
• Provides antioxidant support.
• Adds light hydration in essence and toner form.
• Popular for calming skin during breakouts.
• Works well in multi-layer Korean routines.

How to Use Mugwort

Use a mugwort essence or toner after cleansing, patting it into the skin before serums. Mugwort clay masks and wash-off masks can be used once or twice a week. It fits easily into a Korean skincare routine as the essence or toner step.

On days when skin is reactive, a simple routine of a mugwort essence and a gentle moisturizer is a good reset. Some people apply the essence with clean hands in several thin layers, pressing each one in, to build hydration without a heavy feel. Fermented mugwort products have a slightly different texture but are used the same way.

Side Effects & Precautions

Mugwort is in the Asteraceae family, the same family as ragweed, chamomile and daisies. People with known allergies to these plants, or to mugwort pollen, may react to it on the skin. Do a patch test before full use, and stop if itching, swelling or a rash appears.

Mugwort also has a naturally herbal scent, and some products add extra fragrance or essential oils to enhance it. If you have reactive skin, look for formulas that keep the ingredient list short. Mugwort clay masks can be drying if left on until fully set, so rinse them while still slightly damp and follow with a hydrating layer. Traditional practices such as steaming or burning mugwort are different from topical skincare and are not covered here.
