Buying guide

THTHERAPY buying guide: handmade Korean soap and herbal care

THTHERAPY is a Korean brand built around handmade cleansing bars and herbal skincare. Most of the range is soap, made with food-grade and botanical ingredients like mugwort, persimmon, sesame, rice bran, and coconut, with an erseongcho refine toner and lotion extending the same herbal base past the wash-off step. This guide covers what is in the range and where each piece fits.

What THTHERAPY is

THTHERAPY centres on handmade soap rather than the serum-and-essence stack most Korean brands lead with. The bars are formulated around single botanical or food-grade ingredients, so each one reads more like a kitchen-and-garden recipe than a lab formula. Alongside the soaps sit a smaller set of leave-on products, the erseongcho refine toner and the matching lotion, which take the brand's herbal signature into a fuller routine.

The soap lineup

The core of the collection is a row of 100g bars, each named for its hero ingredient: coconut, sesame, rice bran, fortified wormwood, and yulpi (persimmon). There is also the seongchobinu line, including a renewed seongchobinu soap and a 100g erseongchobinu bar built on mugwort. Because the bars share a size and base, the practical choice is which ingredient you want against your skin rather than which formula is stronger.

The herbal ingredients and what they bring

Mugwort (erseongcho) runs through the seongchobinu bars and the toner and lotion, and it is the ingredient Korean herbal skincare reaches for when skin feels reactive or congested. Persimmon (yulpi) shows up in its own soap, sesame and rice bran bring a softer, food-derived feel, and coconut gives a more conventional cleansing bar. Picking a bar is mostly picking which of these you want to wash with day to day.

Where the toner and lotion fit

The erseongcho refine toner (200ml) and the 200ml erseongcho refine lotion are the leave-on half of the range. The toner is the step after cleansing, used to wipe or pat over freshly washed skin, and the lotion seals the routine. Both keep the mugwort base, so they pair naturally with the seongchobinu bars if you want one herbal thread from cleanse to moisturise.

How to choose your first bar

If you want the brand's signature, start with a seongchobinu or erseongchobinu mugwort bar. If you would rather a gentler, food-derived wash, the sesame or rice bran soap is the easier entry. Coconut is the most familiar everyday option, and yulpi (persimmon) is the one to try if you specifically want that ingredient. Since the bars are 100g and share a base, it is low-cost to buy two and compare.

How to use the bars and leave-on steps

Work a bar into a lather with wet hands or a cloth, massage over damp skin, and rinse. Handmade soaps last longest when they dry fully between uses, so keep the bar on a draining dish rather than sitting in water. After cleansing, the erseongcho toner goes on next, then the lotion. You do not need every step from the start; a bar plus the toner is a sensible two-step beginning.

Sizing and value

The soaps are sold as 100g bars, a standard size that makes it easy to compare ingredients without committing to one for months. The toner and lotion come in 200ml bottles, enough for daily use over a long stretch. Buying a couple of bars to test before settling on a regular one is the cheapest way to find your fit across the range.

Korean sourcing and authenticity

THTHERAPY is a Korean brand, and the soaps carry Korean product names (seongchobinu, erseongcho, yulpi) that point back to their botanical roots. We list 24+ THTHERAPY products sourced as genuine Korean stock, so the bar or bottle you receive matches the brand's own range rather than a relabelled substitute.

FAQ

Frequently asked questions

  • Mostly handmade soap. The range is built on 100g bars made with single ingredients like coconut, sesame, rice bran, wormwood, and yulpi (persimmon), plus the seongchobinu mugwort bars. There is also an erseongcho refine toner and lotion for the leave-on steps. We list 24+ THTHERAPY products in total.

  • For the brand's signature, start with a seongchobinu or erseongchobinu mugwort bar. For a gentler food-derived wash, the sesame or rice bran soap is easier, and coconut is the most familiar everyday choice. Since the bars are 100g and share a base, buying two to compare is low-cost.

  • Erseongcho is mugwort, a herb Korean skincare leans on for reactive or congested skin. THTHERAPY uses it as the through-line of the brand, in the seongchobinu soap bars and in the erseongcho refine toner and lotion, so you can keep one herbal ingredient from cleanse to moisturise.

  • The soap is your cleanse step. After washing, the 200ml erseongcho refine toner goes on next, then the matching lotion seals the routine. All three share the mugwort base, so a seongchobinu bar plus the toner is a natural two-step start before you add the lotion.

  • Yes. THTHERAPY is Korean, and its product names (seongchobinu, erseongcho, yulpi) trace back to their botanical roots. The 24+ items we list are sourced as genuine Korean stock, so what you receive matches the brand's own range.
