Toun28 Soap
TOUN28's soap line is mostly a run of slightly-acidic S-numbered face washes - solid cleansing soaps built around one hero ingredient each, from S1 rosehip and shea butter to S10 ceramide and S11 ceramide-squalane, plus a S9 Houttuynia and Centella version for sensitive, reactive skin. The range also covers an S23 grapefruit body wash bar and an S12 evening primrose infant soap, so the S-number is the fastest way to tell a gentle everyday face wash apart from a targeted or body-specific bar.

TOUN28 Soap Guide: S-Number Face Washes Explained
Most of TOUN28's soap range is a face wash, not a body bar - each S-number solid soap is built around a single hero ingredient and a slightly acidic pH meant to sit closer to skin's natural balance than a standard alkaline bar. This guide walks through what each numbered formula targets so you can pick by skin need rather than by scent.
Why 'slightly acidic' matters on the label
Most of TOUN28's face wash soaps are labeled slightly acidic, which means the bar is formulated closer to skin's natural pH than a typical alkaline soap. That matters most for reactive or barrier-compromised skin, where an alkaline wash can leave skin feeling tight or stripped right after rinsing.
S1 and S10 for dry or barrier-stressed skin
S1 pairs rosehip oil with shea butter for a richer, more cushioning cleanse, while S10 leans on ceramide to support the skin barrier during the wash step itself. S11 goes further, combining ceramide with squalane for a formula marketed as lasting moisture - worth trying if S10 still feels slightly drying for your skin.
S9 for sensitive or easily irritated skin
S9 pairs houttuynia (eoseongcho) with centella asiatica, two ingredients commonly used in Korean skincare to calm redness and reactivity, and it's sold as a 2-pack. If your skin flushes or stings with most cleansers, S9 is the formula built specifically for that.
S3 and S8 for oil control and congestion
S3 combines calamine with hyaluronic acid for oil absorption without sacrificing hydration, while S8 uses sulfur, salt, and castor oil for a more purifying, deep-clean formula. Both lean toward oilier or congestion-prone skin rather than dry or sensitive types.
S15 for a nourishing, elasticity-focused wash
S15 is built around propolis and honey, positioned for elasticity and nourishment rather than oil control or barrier repair specifically. It suits normal-to-dry skin looking for a softer, more conditioning face wash.
Beyond the face: S23 body wash and S12 infant soap
Not every bar in this collection is a face wash - the S23 Grapefruit Oil bar is a body wash aimed at skin elasticity and evening tone on the body, and the S12 Evening Primrose Oil soap is formulated specifically for infant skin. Check the product title before assuming every TOUN28 soap here is meant for the face.
How to use a TOUN28 face wash soap
Work the bar between wet hands or a soft cloth to build a light lather, apply to a damp face, and rinse thoroughly. Because the bar sits on a dish rather than staying sealed like a bottle, letting it dry out between uses keeps it from turning soft or mushy before it's used up.
Picking your S-number
Match the number to the concern rather than the price or packaging: S1/S10/S11 for dryness and barrier support, S9 for sensitivity, S3/S8 for oil and congestion, S15 for a nourishing everyday wash, and S23/S12 for body or infant use specifically.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Which TOUN28 soap S-number is best for dry skin?
S1 (rosehip oil and shea butter) and S10/S11 (ceramide-based, with S11 adding squalane) are the formulas built for dryness and barrier support. Between the two ceramide options, S11 is positioned as the more moisturizing of the pair.
Is there a TOUN28 soap for sensitive or reactive skin?
S9 combines houttuynia and centella asiatica specifically for sensitive, easily irritated skin, and it's sold as a 2-pack. It's the formula to reach for if most cleansers leave your skin red or stinging.
Are all the TOUN28 soaps in this collection face washes?
No - most are S-numbered face washes, but S23 (grapefruit oil) is a body wash bar and S12 (evening primrose oil) is formulated for infant skin. Check the product title to confirm before buying.
What does 'slightly acidic' mean on a TOUN28 soap?
It means the bar is formulated closer to skin's natural pH than a standard alkaline soap, which is generally gentler on the skin barrier and less likely to leave skin feeling tight after rinsing. Most of the S-numbered face washes in this range carry that label.
Which TOUN28 soap works best for oily or congested skin?
S3 pairs calamine with hyaluronic acid for oil absorption without over-drying, while S8 uses sulfur, salt, and castor oil for a deeper, more purifying clean. S8 is the stronger option if congestion is the main concern.
How long does a TOUN28 soap bar typically last?
Because it's a solid, water-free cleanser rather than a liquid face wash, a bar generally lasts longer per gram than a bottled cleanser of the same size, provided it's kept on a draining dish instead of sitting in water between uses.
