Mugwort in Skincare: Why Korean Brands Love It

 By Victoria  |  K-Beauty Ingredients · Education

Mugwort — 쑥 (ssuk) in Korean — has been used in East Asian traditional medicine for over 2,000 years. It shows up in Korean cuisine, in moxa therapy, and increasingly, in some of the most beloved K-beauty products of the past decade. COSRX's Mugwort line, Some By Mi's Mugwort Mask, and Beauty of Joseon's Ginseng + Mugwort formulas have introduced this ancient botanical to a global skincare audience — and for good reason.

What Is Mugwort?

Mugwort (Artemisia vulgaris or Artemisia princeps) is a perennial plant in the daisy family. In Korean skincare, Artemisia princeps — the Korean variety — is most commonly used, though Artemisia vulgaris and Artemisia capillaris also appear in formulas. The plant contains several bioactive compounds: flavonoids (particularly jaceosidin and eupatilin), volatile oils, tannins, and vitamins C and E. Together these compounds deliver the anti-inflammatory, antibacterial, antioxidant, and soothing effects that make mugwort so effective in skincare.

In K-beauty, mugwort extract is typically listed as Artemisia princeps leaf extract or Artemisia vulgaris extract on ingredient lists. Its characteristic light green-to-green color gives mugwort products their distinctive hue — the green tint in COSRX's Mugwort Pore Serum is entirely natural.

What Mugwort Does for Skin

Calms inflammation and redness. The flavonoids in mugwort — particularly jaceosidin — inhibit inflammatory pathways (COX-2 inhibition) that drive skin redness, sensitivity, and irritation. For reactive and rosacea-prone skin, mugwort provides immediate visible calming.

Antibacterial. Active against Staphylococcus epidermidis and Propionibacterium acnes — the bacteria most associated with acne and skin infection. This makes mugwort particularly useful for acne-prone skin as both a preventive and treatment ingredient.

Antioxidant protection. The combination of flavonoids, vitamins C and E, and tannins provides broad antioxidant activity — neutralizing free radicals from UV exposure and pollution that cause premature aging.

Pore refinement. The mild astringent properties of mugwort tannins contribute to tighter, cleaner-looking pores — particularly effective after cleansing.

Barrier support. Eupatilin — one of mugwort's key flavonoids — has been shown to strengthen the skin barrier and reduce transepidermal water loss, supporting moisture retention long-term.

Mugwort vs Centella Asiatica: Which Calming Botanical Is Right for You?

Mugwort and centella are the two dominant calming botanicals in K-beauty, and they're often compared. Both calm inflammation and support the barrier — but their profiles differ:

Choose mugwort if: Your skin is acne-prone (mugwort's antibacterial activity targets acne bacteria directly), you have oily or combination skin with visible pores, or you want antioxidant protection alongside calming benefits.

Choose centella if: Your skin is very sensitive or damaged, you're post-procedure, or you need the most intensive barrier repair. Centella's collagen-stimulating properties (madecassoside, asiaticoside) give it an anti-aging dimension that mugwort doesn't match.

Use both if: You have sensitive, acne-prone skin — mugwort handles the bacteria and antioxidant protection while centella handles the barrier and healing.

FAQ

Is mugwort safe for sensitive skin?
Yes — mugwort is one of the gentlest botanical actives in K-beauty. It's fragrance-free in most formulations and well-tolerated by reactive skin. Patch test if you have known plant allergies (particularly to the daisy/Asteraceae family).

Can mugwort be used during pregnancy?
Topical mugwort extract at cosmetic concentrations is generally considered safe. Mugwort essential oil and internal use should be avoided during pregnancy — but the cosmetic extract in skincare formulas is different from concentrated essential oil.

Does mugwort have a scent?
In whole-plant form, mugwort has a mild herbal, slightly woody scent. In skincare formulations, most mugwort extracts are deodorized — COSRX and I'm From mugwort products are near-scentless.

Korean Skincare Routine for Beginners (2026): 5-Step Glass Skin Guide

By Victoria | Updated May 2026 | You've heard about glass skin. You've seen the glowing, poreless, almost luminous complexion all over TikTok and Instagram — and it all traces back to one place: Korea. But where do you even start? I'm from Seoul, and I've been following a version of this routine for over 10 years. What surprises most of my readers is this: the famous "10-step routine" was never meant to be done every single day. It's a menu — you pick what your skin needs. For a complete beginner in 2026, 5 steps are all you need to start seeing real results. What Is the Korean Skincare Routine? The Korean skincare routine is a layered approach that prioritizes hydration, prevention, and skin barrier health over harsh correction.

Korean Sunscreen vs Western Sunscreen: Which Actually Protects Better? (Tested)

Image
By Victoria | Updated May 2026  If you've ever tried a Korean sunscreen after years of using Western SPF, you'll understand why so many people never go back. The texture is different. The finish is different. Even the way it sits under makeup is different. But is it actually better at protecting your skin? Or is it just more pleasant to use? Victoria's Note: At K&Global, SPF was one of the most requested categories from international buyers — especially from Southeast Asian markets where UV intensity is extreme. What surprised many buyers was how much better Korean SPF formulas performed under makeup compared to Western options they'd been using. That feedback confirmed something I already knew from living in Seoul: Korean sunscreen isn't just more pleasant — it's genuinely engineered for daily real-world use in a way most Western formulas aren't. I've been testing sunscreens from both sides for years — living in Seoul, where SPF is treated as se...
