TOUN28 Face Wash: S-Series Cleansing Soap Buyer's Guide
TOUN28 takes an ingredient-first approach to facial cleansing: each Face Wash in the S-series is a 100g solid soap with a different active ingredient pairing designed to target a specific skin concern. The 9 soaps range from oil-absorbing Calamine to ceramide-based moisturizing formulas to Amazon Mud. This guide maps each S-series product to its active ingredients, its intended skin concern, and who should choose it over the others.
Why TOUN28 Uses Solid Bar Format
Solid cleansing bars offer a higher active ingredient concentration than foaming gel cleansers because they do not require the preservative systems and water content that liquid formulas need. TOUN28 uses this format to pack functional actives - ceramide, squalane, sulfur, castor oil, propolis - into a stable 100g bar. The bar format also uses less packaging per product and is easy to travel with.
All TOUN28 Face Wash products are noted as 'slightly acidic' or 'weakly acidic' on the formulas that include pH descriptors (S2, S3, S10, S11). Korean skincare emphasizes low-pH cleansing as a way to preserve the skin's acid mantle and reduce post-cleanse tightness - the slightly acidic pH range is around 5.5, which is closer to skin's natural pH than traditional alkaline bar soaps.
S10 and S11: Ceramide-Based Formulas
Two soaps in the S-series use ceramide as the main active. The S10 Ceramide Elasticity Slightly Acidic Cleansing Soap (100g) pairs ceramide with an elasticity focus - suited to skin that feels lax or has lost some firmness. The S11 Ceramide Squalane Lasting Moisturizing Slightly Acidic Cleansing Soap (100g) adds squalane to the ceramide base, targeting skin that needs both barrier repair and sustained moisture. Both are slightly acidic, so they work without disrupting the skin's acid mantle.
For dry skin that wants a cleansing soap rather than a foam, S11 is the most moisturizing option in the range because squalane is a highly effective emollient. If skin concerns are more about texture and firmness than dryness, S10's elasticity focus is the better pick.
S3 and S8: Oil Absorption and Sulfur Salt
The S3 Calamine Hyaluronic Acid Oil Absorption Cleansing Soap targets combination and oily skin. Calamine (zinc oxide and iron oxide mixture) is a traditional oil-absorbing ingredient that controls shine and calms mild inflammation. The hyaluronic acid in S3 prevents the over-drying that pure oil-absorbing formulas can cause. This balance makes S3 practical for oily skin that still needs some hydration post-cleanse.
The S8 Sulfur Salt Castor Oil Cleansing Soap (100g) targets acne-prone skin more directly. Sulfur is an anti-bacterial and keratolytic active that has been used in acne treatment for decades. Castor oil in the formula prevents the drying effect that sulfur alone can cause. S8 is suited to active breakout skin that can tolerate a mild sulfur cleanser.
S7 and S16: Botanical Oil Formulas
The S7 Noni + Tamanu Oil Face Wash (100g) combines two tropical plant oils. Tamanu oil has documented anti-inflammatory and wound-healing properties often used in post-acne scar care; noni fruit provides antioxidant coverage. Together they make S7 a good choice for post-acne skin that still has some hyperpigmentation or texture from previous breakouts.
The S16 Camellia + Grapefruit Oil Face Wash (100g) pairs camellia oil - a light, non-comedogenic oil widely used in Japanese and Korean skincare for its oleic acid content - with grapefruit for a brightening angle. S16 suits normal to dry skin that wants a nourishing cleansing experience with some radiance benefit.
S15 Propolis and Honey
The S15 Propolis + Honey Face Wash (100g) draws on two ingredients associated with anti-bacterial and moisture-retention properties. Propolis is a bee-derived compound with well-established antimicrobial and anti-inflammatory activity in skincare research. Honey is a humectant and mild antibacterial. Their combination targets skin that is prone to breakouts but still needs gentleness and hydration - a different angle from the more aggressive S8 sulfur formula.
S15 sits between the oil-control and moisturizing camps in the TOUN28 range. It is a reasonable starting choice for mildly acne-prone skin that finds sulfur too drying or too clinical.
S17 Amazon Mud
The S17 Amazon Mud Face Wash (100g) uses mud as a drawing and detoxifying ingredient. Mineral-rich muds adsorb excess oil and skin surface impurities during cleansing. The Amazon Mud source points to a high-mineral-content clay base. This formula is suited to oily skin or congested pores that benefit from a drawing cleanser rather than a pure surfactant foam.
S17 functions as a deeper daily cleanse option within the TOUN28 range. It is not a once-weekly mask but a daily bar, so its approach is gentler than a concentrated clay mask, appropriate for regular use without over-stripping.
S2 Lean Seed Oil (Weakly Acidic)
The S2 Lean Seed Oil Weakly Acidic Cleansing Soap (100g) uses lean seed oil - a plant seed oil with a high essential fatty acid content - in a weakly acidic base. This is the most moisture-focused formula in the range alongside S11, and the 'weakly acidic' descriptor emphasizes barrier-friendly pH. S2 is well suited to dry or normal skin that wants a simple, nourishing daily cleanse without functional actives like ceramide, sulfur, or mud.
The weakly acidic designation is one step below 'slightly acidic' - both describe pH ranges below 7, with weakly acidic suggesting a more pronounced acid-mantle compatibility. For skin with chronic dryness or compromised barrier, S2 is the least interventional daily cleanser in the TOUN28 range.
How to Choose Between TOUN28 S-Series Soaps
The clearest way to choose is by primary skin concern: oily or congested skin - S3 Calamine HA or S17 Amazon Mud. Active acne - S8 Sulfur Salt Castor Oil. Post-acne texture and hyperpigmentation - S7 Noni Tamanu Oil. Dry, barrier-compromised skin - S11 Ceramide Squalane or S2 Lean Seed Oil. Mild blemish-prone skin that needs gentleness - S15 Propolis Honey. Normal skin wanting nourishment with radiance - S16 Camellia Grapefruit Oil. Elasticity and firmness focus - S10 Ceramide Elasticity.
Since each bar is 100g, the cost of trialing a formula is low. If your skin concern shifts seasonally - oilier in summer, drier in winter - you can keep two S-series bars on hand and rotate based on your skin's current state.

Frequently asked questions
FAQ
Frequently asked questions
Which TOUN28 Face Wash is best for oily skin?
The S3 Calamine Hyaluronic Acid Oil Absorption Cleansing Soap and the S17 Amazon Mud Face Wash are the best options for oily skin in the TOUN28 range. S3 uses calamine to absorb excess oil while hyaluronic acid prevents over-drying. S17 uses mineral-rich mud to draw out oil and impurities. Both are 100g bars suited for daily use on oily skin.
Which TOUN28 Face Wash targets acne-prone skin?
The S8 Sulfur Salt Castor Oil Cleansing Soap is the most targeted acne formula in the TOUN28 range. Sulfur has antimicrobial and keratolytic properties that address active breakouts. Castor oil balances the drying effect of sulfur. For mildly acne-prone skin that finds sulfur too strong, the S15 Propolis + Honey Face Wash provides gentler antibacterial action with more hydration.
What is the difference between the TOUN28 S10 and S11 ceramide soaps?
The S10 Ceramide Elasticity Slightly Acidic Cleansing Soap (100g) focuses on skin firmness alongside barrier support from ceramide. The S11 Ceramide Squalane Lasting Moisturizing Slightly Acidic Cleansing Soap (100g) adds squalane for enhanced moisture retention. Choose S10 if your primary concern is elasticity and skin texture. Choose S11 if your primary concern is dryness and sustained post-cleanse moisture.
What does slightly acidic or weakly acidic mean on TOUN28 soaps?
Slightly acidic and weakly acidic describe the pH of the cleanser, which is below 7. Skin's natural acid mantle sits around pH 4.5-5.5. Most traditional bar soaps are alkaline (pH 9-10), which temporarily raises skin pH after washing. TOUN28's slightly acidic and weakly acidic soaps are formulated closer to skin's natural pH, which reduces post-cleanse tightness and helps maintain the acid mantle's protective function.
Why does the TOUN28 S7 Face Wash contain tamanu oil?
Tamanu oil has documented anti-inflammatory and wound-healing properties. In skincare it is used specifically for post-acne hyperpigmentation and textural scarring. The S7 Noni + Tamanu Oil Face Wash (100g) is formulated for skin recovering from acne - not active breakout treatment, but the repair and evening of tone and texture that follows. Tamanu oil combined with noni's antioxidant content makes S7 the most skin-repair-focused cleanser in the TOUN28 range.
Who should use the TOUN28 S15 Propolis + Honey Face Wash?
The S15 Propolis + Honey Face Wash (100g) suits mild to moderately blemish-prone skin that needs antibacterial action without the harshness of sulfur. Propolis provides antimicrobial and anti-inflammatory properties; honey adds humectant moisture. S15 is a good middle-ground option for combination skin with occasional breakouts that finds S8 too drying but still wants more than a basic cleanse.
How long does a 100g TOUN28 Face Wash bar last?
A 100g solid cleansing bar typically lasts 4 to 8 weeks with daily use, depending on how much is lathered per wash. Bar soaps used with a lathering net or gloves require less product per use. Keeping the bar dry between uses (not sitting in a pool of water) significantly extends its life by preventing the bar from softening and dissolving faster than it is used.
How do I use a TOUN28 Face Wash bar?
Wet your hands and the bar, then lather the soap between wet palms until you have a foam. Apply the foam to a wet face and massage for 30-60 seconds, focusing on any congested or oily areas. Rinse thoroughly with lukewarm water. Using a cleansing net produces a denser, gentler foam that requires less product per wash and reduces the need to rub the bar directly against your face. Follow with toner immediately after rinsing to restore moisture balance.
Can I use the TOUN28 S17 Amazon Mud Face Wash every day?
Yes. The S17 Amazon Mud Face Wash (100g) is formulated as a daily cleansing bar, not a once-weekly mud mask treatment. The mud content provides a drawing and detoxifying effect during the wash and rinse cycle rather than a prolonged mask application. Daily use is appropriate for oily or congested skin. For drier or sensitive skin, daily use of a mud cleanser may be too clarifying - those skin types should opt for S11, S2, or S10 instead.
What skin type is the TOUN28 S16 Camellia + Grapefruit Oil Face Wash suited to?
The S16 Camellia + Grapefruit Oil Face Wash (100g) is best suited to normal to dry skin. Camellia oil is a lightweight non-comedogenic oil high in oleic acid that nourishes without clogging pores. Grapefruit adds a brightening note for a cleaner, more radiant finish. This formula is not suited to oily or acne-prone skin that is sensitive to oil-based cleansers. For oily skin, S3 or S17 are better choices.
