Cleansers are the unsung heroes of any skincare routine. Nobody posts their face wash on social media for clout, but use the wrong one and everything else in your routine fights an uphill battle. The Round Lab 1025 Dokdo Cleanser has been steadily gaining cult status in K-beauty circles, praised for being gentle enough for the most reactive skin while still actually cleaning your face. That's a balance most cleansers get wrong.
After four weeks of using it as my sole morning and evening cleanser, I can tell you whether that reputation holds up — and where it falls short.
First Impressions
The packaging is clean and ocean-themed — a nod to the Dokdo deep sea water that gives this cleanser its name. It's a 150ml squeeze tube, sturdy and practical. Nothing about it screams luxury or hipness; it looks like a serious skincare product that doesn't need bells and whistles.
Squeezing out the first amount, the texture is a low-foam gel — semi-translucent, very slightly thick, almost like a diluted hair gel. It's not a rich cream cleanser and it's not a foaming face wash. It occupies this middle ground that I've come to associate with well-formulated Korean cleansers.
Lathered in my hands with water, it produced a soft, thin lather — nothing like the thick foam of a sulfate-based cleanser. First wash felt incredibly gentle. Almost too gentle, honestly. I found myself wondering, "Did this actually clean anything?" But my skin felt clean to the touch without any tightness, which was a good sign. No fragrance that I could detect.
Key Ingredients
The "1025" refers to the Ulleungdo deep sea water sourced from 1,025 meters below the surface near Dokdo Island in Korea. This isn't a gimmick — deep sea water at that depth is rich in minerals (magnesium, calcium, potassium, and zinc) that have been shown in dermatological studies to support skin hydration and barrier function. It's a meaningful ingredient, not just a marketing story.
The formula also includes panthenol for soothing and moisture retention, hyaluronic acid for hydration (unusual in a cleanser, and welcome), and betaine as a gentle surfactant that cleans without stripping. The pH is formulated to be slightly acidic (around 5.5-6.0), matching the skin's natural pH — which is important because many cleansers are too alkaline and compromise the acid mantle.
What's notably absent: sulfates (SLS/SLES), parabens, artificial fragrance, essential oils, and alcohol. The ingredient list is clean without being performatively minimalist. Every ingredient serves either a cleansing or a skin-caring function.
How I Used It
I used the Dokdo Cleanser twice daily — once in the morning on bare skin, and once in the evening as my second cleanser (after an oil cleanser for makeup and sunscreen removal). I dispensed about a nickel-sized amount, worked it into a lather in my wet hands, then massaged it across my face for about 30-45 seconds before rinsing with lukewarm water.
For testing purposes, I also tried it a few times as my only evening cleanser (no double-cleanse) to see how it handled light makeup and sunscreen on its own. My skin during testing: combination, occasionally reactive, with some mild redness on the cheeks. I was also using a vitamin C serum and a lightweight moisturizer in my routine.
Results After 4 Weeks
Gentleness: This is where the Dokdo Cleanser absolutely excels and earns its reputation. In four weeks of twice-daily use, my skin never once felt stripped, tight, or dry after washing. Not once. For someone with combination skin that's prone to post-cleanse tightness, that's remarkable. The days I used a harsher cleanser as a comparison (week 3, for science), I immediately noticed the difference — the Dokdo formula was clearly much kinder to my skin.
Cleansing ability: Here's the honest truth — as a sole cleanser for heavy makeup and waterproof sunscreen, it's not quite enough. I could feel a slight film remaining when I tried to use it without oil cleansing first on heavy makeup days. However, as a second cleanser (after oil cleansing) or as a morning cleanser, it's perfect. It removes light residue, overnight products, and natural sebum without issue.
Skin condition: Over the four weeks, my overall skin condition improved noticeably. The mild redness on my cheeks calmed down — I attribute this partly to the gentle, pH-balanced formula not aggravating it twice a day. My skin's texture felt smoother, and my other products (vitamin C, moisturizer) seemed to perform better on properly cleansed but not stripped skin.
Hydration: My face felt more hydrated post-cleanse than with any previous cleanser I've used. The hyaluronic acid and deep sea minerals genuinely seem to leave something beneficial behind, even in a rinse-off product. I know that sounds counterintuitive, but the difference was noticeable.
Breakouts: I had one small blemish during week 2, which I attribute to hormonal timing rather than the cleanser. Overall, my skin was clearer and calmer than usual over the testing period.
Who Should (and Shouldn't) Use This
Ideal for: Sensitive skin types — this might be the gentlest effective cleanser I've ever used. People with dry or dehydrated skin who find most cleansers stripping. Anyone practicing a double-cleanse method who needs a reliable, gentle second step. People dealing with redness, irritation, or compromised barriers who need to minimize aggravating factors. It's also great as a morning cleanser for literally any skin type.
Less ideal for: If you wear heavy, full-coverage makeup daily and want a single-step cleanse, this won't cut it alone — you'll need an oil cleanser first. People with very oily skin who prefer that "squeaky clean" feeling may find this underwhelming (though that squeaky feeling is actually your barrier being stripped, but I understand the preference). If you want a cleanser with active ingredients like salicylic acid or glycolic acid built in, this isn't that product.
Pros & Cons
Pros:
- Exceptionally gentle — no stripping, tightness, or dryness whatsoever
- pH-balanced formula (5.5-6.0) that respects the skin's acid mantle
- Deep sea mineral water provides genuine hydrating and skin-supporting benefits
- Contains hyaluronic acid and panthenol — unusual and valuable in a cleanser
- No fragrance, sulfates, or common irritants
- Skin redness and irritation visibly calmed over 4 weeks
- Works for virtually all skin types as a morning or second cleanser
Cons:
- Insufficient alone for removing heavy makeup or waterproof sunscreen
- Low-foam texture may feel "not enough" for those used to rich lathers
- 150ml tube size means frequent repurchases with twice-daily use
- No active treatment ingredients — it's purely a cleanser
The Verdict: 4.5/5
The Round Lab 1025 Dokdo Cleanser earns a strong 4.5 out of 5. In a category where most products are either too harsh or too gentle, this one threads the needle almost perfectly. It genuinely cleans without stripping, leaves skin hydrated rather than tight, and uses meaningful ingredients — not gimmicks — to support skin health. The half-point deduction is for its limitations as a standalone makeup remover, which is honestly an unfair expectation for a water-based cleanser anyway.
If you've ever thought your cleanser might be part of your skin problems rather than the solution, try this one. It changed my perspective on what a good cleanser should feel like.

Frequently Asked Questions
Can the Round Lab Dokdo Cleanser remove makeup on its own?
For light makeup and non-waterproof sunscreen, it does a reasonable job. For heavy, full-coverage makeup or waterproof products, I recommend using an oil cleanser first and following with the Dokdo Cleanser as your second step. It excels in the double-cleanse method.
Is the Round Lab Dokdo Cleanser good for acne-prone skin?
Yes. Its pH-balanced, gentle formula is unlikely to irritate acne-prone skin or strip the barrier (which can actually worsen acne). It doesn't contain salicylic acid or other acne-fighting actives, but it provides a clean canvas for those products to work on afterward.
What does the 1025 Dokdo deep sea water actually do for skin?
The deep sea water is sourced from 1,025 meters below the surface near Dokdo Island and is naturally rich in minerals like magnesium, calcium, potassium, and zinc. Research shows these minerals support skin hydration, strengthen the barrier, and can help calm inflammation. It's a meaningful active ingredient, not just a marketing element.
How does the Round Lab Dokdo Cleanser compare to CeraVe or La Roche-Posay gentle cleansers?
All three are excellent gentle cleansers, but they differ in approach. CeraVe includes ceramides, La Roche-Posay uses thermal water, and Round Lab uses deep sea mineral water. The Dokdo Cleanser has a slightly more hydrating post-wash feel in my experience, with a lower-foam texture. If you've been happy with CeraVe or LRP, this is a K-beauty alternative worth trying for the mineral water benefits and hyaluronic acid inclusion.
