Buying Guide: THTHERAPY 100g Korean Bar Soaps

THTHERAPY's 100g soap collection covers nine bar varieties built around traditional Korean ingredients, fermentation techniques, and plant botanicals. From classic sesame and rice bran formulas to fermented blue tea and wormwood, each bar has a distinct active direction. This guide explains each variety's ingredients and intended use to help you choose the right THTHERAPY bar for your skin type and preferences.

100g Erseongchobinu

Erseongchobinu is a traditional Korean handmade soap that uses a fermentation-based lye process derived from plant ash. The name references an ancient Korean soap-making method where ash from burned rice straw or plant material is leached with water to create an alkaline base for soap. This type of soap is associated with gentle, skin-conditioning properties from the potassium-rich lye and the organic matter carried through from the plant ash fermentation. It suits people interested in traditional Korean cosmetics with historical roots predating synthetic detergents.

100g Sesame Soap

The THTHERAPY Sesame Soap uses sesame seed oil, which is rich in linoleic acid and naturally occurring antioxidants including sesamol and sesamin. Sesame oil has a centuries-long history in East Asian skincare as a nourishing base for dry or mature skin. In bar soap form, its fatty acid profile leaves the skin feeling soft after washing rather than stripped. The sesame soap suits dry to normal skin types and provides a mild, nutty scent from the oil's natural aromatic compounds.

100g Yulpi Soap

Yulpi (율피) means chestnut shell or chestnut bark in Korean. Chestnut shell extract is used in Korean traditional medicine for its high tannin content, which provides astringent and antioxidant properties. In soap form, yulpi extract helps tighten pores, control excess sebum, and protect the skin from oxidative damage. The Yulpi Soap suits combination to oily skin or anyone wanting a firming, toning cleanse rather than a moisturizing one. The distinctive brownish color of yulpi soaps comes from the chestnut extract itself.

100g Coconut Soap

The THTHERAPY Coconut Soap uses coconut-derived ingredients, most commonly coconut oil, which is a staple base in natural soap-making for its high lauric acid content. Coconut soap produces a generous, dense lather and has effective cleansing power for removing sebum and surface debris. On the skin, lauric acid has mild antimicrobial properties, making coconut soap practical for body and hand use. The formula suits normal to oily skin; very dry or sensitive skin may prefer the sesame or rice bran varieties, which have a gentler fatty acid profile.

100g Fortified Wormwood Soap

Wormwood (Artemisia, mugwort in common Korean use) is a well-established Korean traditional medicine botanical with anti-inflammatory and antimicrobial properties. THTHERAPY's fortified wormwood soap concentrates mugwort extract in the bar for a targeted soothing and clarifying effect. Mugwort soap is particularly popular in Korean skincare for sensitive and reactive skin prone to redness. The green tint common in wormwood soaps comes from chlorophyll in the plant extract. This is one of the most distinctively Korean formula directions in the THTHERAPY range.

100g Rice Bran Soap

Rice bran (the outer layer of the rice grain) contains ferulic acid, vitamin E (tocotrienols), and phytic acid, which together provide antioxidant activity and gentle exfoliation. Rice bran soap is a brightening and smoothing formula in Korean skincare - it lightens dullness, reduces oxidative damage, and leaves skin with a slightly luminous texture. The THTHERAPY Rice Bran Soap suits all skin types but is particularly practical for skin seeking a brighter, more even complexion from a facial soap. It is one of the most traditionally used Korean beauty ingredients in bar soap form.

Fish Candle Soap and Fermented Blue Tea Soap

The Fish Candle Soap is a novelty-form soap in THTHERAPY's 100g range, molded into a fish and candle shape. The name refers to the product design rather than a fish-derived ingredient. Korean bar soaps with decorative forms are commonly gifted. The Fermented Blue Tea Soap uses blue tea (butterfly pea flower tea) fermented to concentrate its antioxidant anthocyanins. Blue tea fermentation is a newer direction in Korean cosmetics, providing antioxidant activity alongside the skin-conditioning qualities of the fermentation byproducts. Both soaps are 100g and fit the same range.

Aloe 3% Renewed Aloe Soap 100g

The THTHERAPY Aloe 3% Renewed Aloe Soap specifies a 3% aloe vera concentration, providing a soothing and hydrating active at a measured dose. Aloe vera gel contains acemannan and polysaccharides that calm irritation and support moisture retention. At 3%, it is a practical cleansing product for sensitive or post-sun-exposure skin that needs a gentle, calming wash without harsh surfactants. The 100g size matches the rest of the THTHERAPY collection, making it easy to rotate with other varieties for different days or needs.

Choosing the right THTHERAPY bar for your skin

Dry skin: Sesame or Aloe 3% for their fatty acid and soothing profiles. Oily or congested skin: Coconut or Yulpi for deeper cleansing and pore-tightening. Sensitive or reactive skin: Fortified Wormwood or Aloe 3% for anti-inflammatory botanicals. Dull or uneven complexion: Rice Bran for brightening ferulic acid and phytic acid. Antioxidant focus: Fermented Blue Tea or Rice Bran. Traditional Korean experience: Erseongchobinu or wormwood. Gifting: Fish Candle for its decorative form. With 9+ varieties in the THTHERAPY 100g collection, building a small rotation of two or three bars across different skin needs is straightforward and cost-effective at the 100g bar size.

FAQ

Frequently asked questions

  • Nine THTHERAPY 100g bar soaps are available: Erseongchobinu (traditional fermented), Sesame, Yulpi (chestnut shell), Coconut, Fortified Wormwood, Rice Bran, Fish Candle, Fermented Blue Tea, and Aloe 3% Renewed Aloe Soap.

  • Erseongchobinu (어성초비누) is a traditional Korean soap made using a lye derived from burned plant ash, often rice straw. The ash-leaching process produces a potassium-based alkaline solution rather than sodium hydroxide, resulting in a softer, more conditioning soap. It is one of the oldest soap-making traditions in Korean cosmetics. THTHERAPY's erseongchobinu bar uses this traditional fermented-lye method.

  • Yes. Mugwort (Artemisia/wormwood) has anti-inflammatory and antimicrobial properties that actively soothe reactive and sensitive skin. The Fortified Wormwood Soap is one of the better THTHERAPY options for skin prone to redness and irritation. Patch test on the inner arm first if your skin reacts to botanical extracts. The green color of wormwood soaps comes from the plant chlorophyll and is a normal characteristic of this formula type.

  • Rice bran contains ferulic acid, phytic acid, and vitamin E (tocotrienols). Ferulic acid is an antioxidant that protects against UV-induced damage. Phytic acid provides mild chemical exfoliation that removes dead surface cells. Together, these compounds address dullness by reducing oxidative discoloration and gently resurfacing the skin during each wash. With consistent daily use, a rice bran soap can contribute to a brighter, more even complexion over several weeks.

  • Yes. Yulpi (chestnut shell) extract is high in tannins, which have astringent properties that tighten pores and reduce sebum secretion at the skin surface. The THTHERAPY Yulpi Soap suits combination to oily skin types. Using it as a facial soap can help manage midday shine and congested pores over time. Follow with a light, non-comedogenic moisturizer after washing to prevent the skin from producing excess oil in response to over-drying.

  • The Fish Candle Soap has a decorative molded form, which makes it a natural gift option. The name refers to the soap's fish and candle shape rather than any fish-derived ingredient. It is a functional bar soap in the same 100g size as the rest of the THTHERAPY line, not a display-only item. The decorative form makes it popular for Korean skincare gift sets.

  • At 3%, aloe vera gel provides a measurable dose of acemannan and polysaccharides, which calm irritation and support moisture retention during and after washing. Korean cosmetics that specify ingredient concentrations on the label meet the disclosure requirement for active claims. The 3% level makes this bar practical for post-sun, post-procedure, or reactive skin that benefits from every product in a routine actively soothing rather than neutral. It is gentler than soaps with higher astringent actives like the Yulpi or Coconut varieties.

  • Blue tea (butterfly pea flower, Clitoria ternatea) has a deep indigo color from anthocyanin pigments, which are potent antioxidants. The fermented version concentrates these pigments through microbial action, which increases bioavailability. In a soap, fermented blue tea provides antioxidant protection at the point of cleansing. The indigo color also gives the soap its distinctive blue-purple appearance.

  • Yes. Skinsli sources THTHERAPY products directly from Korean B2B suppliers and ships them to US customers. All THTHERAPY 100g bar soaps listed are authentic Korean market items.

  • Most THTHERAPY varieties are formulated as face and body soaps. The rice bran, aloe, erseongchobinu, and wormwood bars are gentle enough for facial use with their soothing or brightening active directions. The coconut and yulpi bars have stronger cleansing action that suits body use or oily facial skin but may be drying for sensitive facial skin. Use any bar on a wet face, lather in hands first, and apply the foam rather than rubbing the bar directly on the face to control the dose.
