The full review.
While the industry markets breakthrough actives and clinical concentrations, the Etude Soon Jung pH 5.5 Relief Toner offers something different: the absence of irritants. The product is defined by what it leaves out. This restraint makes it a top recommendation in the global sensitive skin community.
It has thirteen ingredients. You can read the entire INCI list in the time it takes to shake the bottle. Water, propanediol, glycerin, betaine, madecassoside, green tea extract, skullcap root extract, and a few texture and preservation agents make up the formula. There are no surprises or complex ingredients to evaluate. For anyone who cross-references a toner’s ingredient list against a comedogenic database, this simplicity works.
The pH 5.5 formulation is a functional design choice. The skin’s acid mantle, which protects against bacteria and moisture loss, sits at pH 4.5-5.5. Cleansing, especially with foaming or soap-based cleansers, raises this pH and leaves the barrier vulnerable. Applying a pH-matched toner after cleansing restores the acid mantle faster and reduces this vulnerability. For chronically reactive skin, these small adjustments matter.
The humectant system uses three layers: glycerin, propanediol, and betaine. Each works differently—glycerin forms hydrogen bonds with water, propanediol improves penetration and feel, and betaine stabilizes cellular hydration as an osmolyte. Together, they hydrate more thoroughly than a single humectant. The Etude Soon Jung pH 5.5 Relief Toner quenches skin rather than just sitting on the surface.
Madecassoside provides therapeutic benefits. As a purified triterpene from Centella asiatica, it offers anti-inflammatory and wound-healing effects. Research shows madecassoside stimulates collagen synthesis, promotes fibroblast proliferation, and inhibits inflammatory cytokines. In this toner, it helps irritated skin heal.
The texture is a lightweight liquid with enough viscosity to cling to your palm. It absorbs in seconds without leaving a film, residue, or sensation. For sensitive skin users who worry if a product “will sting,” the lack of sensation is reassuring. It disappears and leaves skin feeling calmer.
The Etude Soon Jung pH 5.5 Relief Toner is ideal for the Korean seven-skin method. The minimal formula prevents ingredient overload when stacking three, five, or seven layers. Each layer adds weightless hydration, creating a dewy, plumped base that helps subsequent products absorb better.
The 200 mL bottle lasts three to five months with twice-daily application, or less if using the seven-skin method. The 350 mL size offers better value. The packaging uses clear plastic and a disc cap; it is functional, hygienic, and recyclable.
The Etude Soon Jung pH 5.5 Relief Toner does not treat active skin conditions, provide anti-aging benefits, or deliver dramatic results. It does not brighten, exfoliate, mattify, or firm. It hydrates, soothes, maintains pH balance, and stays out of the way. This is exactly what most people with sensitive, reactive, or post-procedure skin need.
The Etude Soon Jung pH 5.5 Relief Toner is popular in the K-beauty community because of its simplicity. While other products compete to add trending ingredients, this toner succeeds by knowing what to leave out. It does not win awards for innovation, but for people whose skin needs to be left alone, it is a top choice.

The science.
The Science
The pH 5.5 formulation is grounded in skin physiology research. Studies published in the British Journal of Dermatology have demonstrated that the skin's acid mantle (pH 4.5-5.5) plays a critical role in barrier function, antimicrobial defense, and enzyme activity. Research has shown that products formulated above pH 5.5 can disrupt the acid mantle and impair stratum corneum integrity, while pH-matched products support barrier recovery.
The triple humectant system leverages three distinct moisture-binding mechanisms. Glycerin, the most extensively studied humectant, has been shown in multiple clinical trials to improve skin hydration and barrier function. A meta-analysis in the British Journal of Dermatology confirmed that glycerin-containing moisturizers significantly reduce TEWL and improve hydration scores. Betaine adds cellular-level protection as an osmolyte — research published in the Journal of Investigative Dermatology demonstrated that betaine protects keratinocytes from osmotic stress, maintaining cellular hydration under challenging environmental conditions.
Madecassoside has demonstrated anti-inflammatory efficacy in multiple published studies. Research in Planta Medica showed that madecassoside inhibits nuclear factor-κB (NF-κB) activation, a key inflammatory pathway. A separate study in the International Journal of Molecular Sciences confirmed its ability to stimulate type I and type III collagen synthesis in fibroblasts, supporting its wound-healing applications.
Scutellaria baicalensis (skullcap) root extract contributes through its primary flavonoid, baicalin, which has documented anti-inflammatory and antioxidant properties. Research has shown that baicalin can suppress UVB-induced MMP expression, suggesting potential photoprotective benefits even in a rinse-off product context.

Dermatologist Perspective
Dermatologists widely recommend pH-balanced, minimal-ingredient toners for patients with sensitive skin conditions including rosacea, eczema, and contact dermatitis. The Soon Jung Relief Toner's pH 5.5 formulation aligns with dermatological guidance to maintain the acid mantle. Board-certified dermatologists note that the humectant-rich formula (glycerin, betaine, propanediol) provides meaningful hydration without introducing sensitizing agents. The madecassoside component is recognized for its anti-inflammatory properties, making this toner appropriate for patients recovering from cosmetic procedures or experiencing acute skin sensitivity. Dermatologists recommend it as a foundational toner step that supports barrier health while being safe to combine with virtually any active treatment.
Guidance
Where it fits in your routine.
Pour a quarter-sized amount into your palm right after cleansing. Press it into your face and neck while skin stays slightly damp. For more hydration, repeat 2-3 times (or up to 7 layers using the Korean layering method), letting each layer absorb for a few seconds before adding the next. Follow with serum and moisturizer. Use morning and evening.
At $20 for 200 mL, the Soon Jung Relief Toner offers great value. The cost per milliliter matches drugstore prices, but the formulation quality — pH-balanced, clinically meaningful actives, and no irritants — beats most drugstore toners. The 350 mL size provides better value for regular users. For sensitive skin consumers who spent hundreds on toners that caused reactions, the reliability of the Soon Jung Relief Toner saves money.
This toner is for sensitive, reactive, rosacea-prone, or post-procedure skin. It works for skincare beginners needing a foolproof first toner, K-beauty enthusiasts using the 7-skin method, and anyone wanting a no-risk hydrating step.
Choose this if you want a toner with exfoliating acids, anti-aging peptides, or visible brightening effects. The Soon Jung Relief Toner provides gentle hydration and soothing, not active treatment. If your skin is robust and you want a multi-functional toner, look elsewhere.

The backstory.
The Soon Jung pH 5.5 Relief Toner became one of the K-beauty sensitive skin community's most recommended products almost immediately after its 2017 launch. Its appeal lies in its radical simplicity — in a market flooded with toners containing 30+ ingredients, the 13-ingredient formula offered sensitive skin sufferers a product they could trust without hours of ingredient research. The 5.5 pH level references the skin's natural acid mantle, positioning the toner as a product that works with the skin rather than against it.

Common myths.
A toner with a water-like texture does nothing for your skin.
Glycerin, propanediol, and betaine in this formula are proven humectants that increase skin hydration. Madecassoside provides anti-inflammatory benefits at concentrations below the sensory threshold. This lack of sensation is intentional — sensitive skin needs a formula that feels like nothing.
All toners need a low pH to exfoliate and clear the skin.
A pH of 5.5 matches the protective natural acid mantle. Exfoliating toners use a pH of 3.5-4.5 to activate acids. This toner hydrates and soothes instead of exfoliating. Maintaining the skin's natural pH helps barrier integrity.
FAQ.
What does the pH 5.5 in the Soon Jung Relief Toner mean?
The toner has a pH of 5.5, matching the skin's natural acid mantle—the slightly acidic film that protects against bacteria and moisture loss. Using a pH-balanced toner after cleansing (which can temporarily raise skin pH) restores this protective layer faster and supports barrier health.
Is the Soon Jung Relief Toner good for acne-prone skin?
Yes — the formula is oil-free, non-comedogenic, and fungal acne safe. Madecassoside provides anti-inflammatory benefits to calm acne-related redness, and the pH 5.5 supports the acid mantle to keep acne-causing bacteria in check. It does not treat active acne, but it is a safe, supportive toner for acne-prone routines.
Can I use this toner with the 7-skin method?
The lightweight, fast-absorbing texture works well for layering. Apply 2-7 thin layers, pressing each into the skin before the next. This builds hydration gradually without stickiness or heaviness. The minimal formula prevents ingredient overload from multiple layers.
Which size should I buy?
The 80 mL size is a low-commitment test for first-time users. For daily use, the 200 mL offers the best value and convenience. The 350 mL jumbo size works best for loyal users who use it for the 7-skin method or on the body.
Does this toner contain panthenol?
The original formulation includes panthenol, but versions vary by market. Check the ingredient list on your specific product — Etude has released multiple versions of the Soon Jung toner over the years, with slight ingredient variations across reformulations.
