Full Review
The distinction between dehydrated and dry skin is one of those textbook dermatology lessons that most skincare shoppers ignore at their own expense. Dehydration is transient — it's what happens when the stratum corneum loses water faster than it's being replenished, and it responds well to humectants, occlusives, and general hydration support. Dry skin is structural — it's what happens when the skin's oil and lipid production is insufficient over time, and it needs different ingredients: emollients, ferments, soothing support, sometimes phytoestrogen-like compounds for mature skin concerns. Round Lab's Dokdo line is designed around the first problem; the Soybean line is designed around the second. Understanding which of the two you actually need is the whole question this toner answers.
The Soybean Nourishing Toner sits at the water-based step of the Soybean routine, paired with the Soybean Nourishing Cream for a two-product approach to dry and mature skin. The first ingredient on the INCI list is fermented Glycine Soja (soybean) seed extract, which replaces purified water as the formula's base and ties the product into Korean traditional skincare aesthetics around fermented soy products as nourishing and softening. Soybean extract carries amino acids, isoflavones like genistein and daidzein, and small peptides, and while the clinical evidence base on topical soybean is smaller than for single ingredients like niacinamide, it's not purely marketing either — published research has suggested possible benefits for mature-skin concerns at meaningful topical concentrations.
The supporting cast is where Round Lab's formulation discipline shows up. Niacinamide at Round Lab's consistent 2% provides broad barrier and tone support without compounding irritation when layered with other Soybean or Dokdo line products. Bifida ferment lysate, a popular Korean probiotic-derived ingredient, adds emerging evidence for skin resilience and recovery. Lactobacillus-fermented soybean extract reinforces the fermentation theme. Panthenol, allantoin, and a botanical tail of centella asiatica, houttuynia, portulaca, licorice, camellia, and rosemary handle soothing and anti-inflammatory support. Humectancy comes from glycerin, sodium hyaluronate, trehalose, and betaine — a slightly heavier load than the minimalist Dokdo Toner to match the nourishing positioning. The whole formula is fragrance-free, alcohol-free, and free of essential oils, and notably, unlike the Soybean Cream, the toner is fungal-acne safe because there are no olive emulsifiers or polysorbates to feed Malassezia.
In use, the toner is slightly more substantial than a minimalist hydrating formula — it's still watery, still absorbs quickly, but there's a noticeable softness and very slight viscosity from the fermented base that distinguishes it from pure humectant toners. Applied by hand-patting in 2-3 layers onto damp skin, it leaves a comfortable, slightly plumped finish without stickiness. Users with dry skin typically report immediate softening and reduced tightness, with cumulative nourishment building over the first few weeks. It's particularly effective in winter or as a dedicated nourishing step for users on retinoids or exfoliating routines that can exacerbate dryness.
The honest limitations are narrow but relevant. Soy allergies are a real concern — the formula is built on soybean extract and includes a second fermented soybean component, so anyone with a soy sensitivity needs to avoid it entirely. Oily and combination-oily skin will probably find it slightly heavier than they want; the 1025 Dokdo Toner is the better fit for those users. The Soybean line is also less famous than the Dokdo line, which means user review volume and long-term commentary is thinner, but the formulation quality is consistent with Round Lab's overall track record. For dry, mature, and winter-compromised skin, this toner is a legitimate upgrade over a minimalist hydrating step, and paired with the Soybean Nourishing Cream, it forms one of the more thoughtful dry-skin routines in K-beauty at this price point. Just make sure your problem is actually dryness and not dehydration before committing — the 1025 Dokdo Toner is still the right call for most users, and picking the wrong Round Lab toner for your skin type will leave you underwhelmed in ways the brand doesn't deserve.

Evidence
Science
The Science
The evidence behind this toner is strongest for the supporting cast rather than the fermentation story. Niacinamide is one of the most rigorously studied ingredients in topical dermatology, with robust evidence for supporting barrier function through increased ceramide synthesis, reducing transepidermal water loss, and improving skin tone through reduced melanosome transfer. Panthenol converts to pantothenic acid in the skin and has published evidence for accelerated barrier repair and reduced inflammation. The humectant blend — glycerin, sodium hyaluronate, trehalose, betaine — draws on well-established water-binding agents with clear evidence for supporting stratum corneum hydration. Allantoin has documented soothing and mild keratolytic activity. The fermentation side of the formula has a smaller but growing evidence base: bifida ferment lysate has published research suggesting benefits for supporting skin resilience, recovery from environmental stress, and reduced UV-induced damage, though these studies are typically smaller than the foundational niacinamide literature. Fermented soybean extract contains isoflavones like genistein and daidzein, which have been studied for their mild phytoestrogen-like activity and possible benefits for mature-skin concerns. The overall coherent story is that the toner's calming and hydration claims are well-supported, while the nourishment claims rest on an emerging but still meaningful evidence base. Compared to Round Lab's 1025 Dokdo Toner, the formulation differences are modest but real — the Soybean Toner is genuinely built for a different skin need, not just a marketing repositioning.
Dermatologist Perspective
Dermatologists frequently recommend toners with humectant support for patients with dry or mature skin, and the Soybean Nourishing Toner fits this clinical frame. Board-certified dermatologists note that fermented ingredients like bifida ferment lysate have emerging evidence for skin resilience, though they typically emphasize that well-studied ingredients like niacinamide and hyaluronic acid carry most of the clinical weight in any given formula. For patients with soy allergies, dermatologists advise strict avoidance of topical products containing soybean extract, which disqualifies this formula for that population. For dry or mature skin patients without soy sensitivities, the fragrance-free, alcohol-free formulation is consistent with what dermatologists generally recommend as a safe hydration step, and the toner layers cleanly with prescription retinoids or other active treatments.
Guidance
Usage Guide
How to Use
Apply after cleansing morning and night. Dispense 2-3 pumps into clean palms and press and pat gently onto damp skin in multiple layers for meaningful nourishment impact — the Korean-style layered approach works especially well with this formula. Alternatively, apply with a cotton round as a pre-serum prep step. Follow with serums, treatments, and a richer moisturizer (ideally the Soybean Nourishing Cream for full-line benefits). Compatible with retinoids, vitamin C, and exfoliating acids. Store at room temperature; use within 12 months of opening.
Value Assessment
At around $19-22 for 200 ml, the Soybean Nourishing Toner is fairly priced relative to its formulation quality and competitive with other fermented Korean toners at twice its volume. Compared to prestige Western fermented-ingredient toners ($40-60 for similar sizes), it undercuts the category significantly. The 200 ml size lasts 2-3 months with twice-daily use, which keeps the cost-per-application reasonable for a targeted nourishing product. For its intended dry-skin audience, the value proposition holds up against most alternatives.
Who Should Buy
Dry, mature, and winter-compromised skin users looking for a nourishing-focused Korean toner with real fermentation support. A strong pick for users committed to the Soybean routine or pairing with the Soybean Nourishing Cream.
Who Should Skip
Users with soy allergies must avoid this product entirely. Oily and combination-oily users will find the 1025 Dokdo Toner better-suited to their skin type. Users looking for a cult hero product will get more consistent reviews and long-term community support from the Dokdo line.

Myth vs. Reality
Myths
Myth
Nourishing toners are just fancy hydrating toners.
Reality
The distinction is real: nourishing formulas typically use a ferment or botanical base, include peptides or amino acid sources, and target skin softening and resilience rather than pure hydration. This toner fits that description, even if some competitor products overstate the difference.
Myth
Fermented ingredients in toners are just marketing.
Reality
Bifida ferment lysate and other fermented actives have emerging evidence for supporting skin resilience and recovery. The evidence base is smaller than for well-studied ingredients like niacinamide, but it's not purely decorative.
FAQ
FAQ
How is it different from the 1025 Dokdo Toner?
The Soybean Toner is built on fermented soybean extract rather than deep seawater and includes fermented actives (bifida ferment lysate, lactobacillus soybean ferment) for a nourishment-focused profile. The Dokdo Toner is a minimalist hydrating formula. Use Soybean for dry, mature, or winter-compromised skin; use Dokdo for daily hydration.
Is it safe for soy allergies?
No — the first INCI ingredient is Glycine Soja (soybean) seed extract, with additional fermented soybean extract lower in the list. Anyone with a soy allergy should avoid this product.
Is it fragrance-free?
Yes — completely unscented, consistent with the rest of Round Lab's main lineup.
Can I use it with retinol or vitamin C?
Yes. The formula is non-reactive and works well as a nourishing buffer step before retinoids or vitamin C. The 2% niacinamide and humectant load specifically help reduce irritation from active routines.
Is it oily for combination or oily skin?
It's slightly richer than a minimalist hydrating toner, so oily skin may prefer the 1025 Dokdo Toner. Combination skin usually tolerates it fine, especially during dry or winter seasons.
