ROUND LAB Dokdo Cleanser: the mineral-rich K-beauty foam that strengthens while it cleanses

What 1025 Dokdo water is and why it matters in skincare

The "1025" in ROUND LAB's product names refers to the depth — 1025 metres below the sea surface — at which the brand sources its deep sea water from the area near Dokdo Island off Korea's eastern coast. At this depth, seawater is free from surface contamination and contains a concentrated profile of trace minerals (magnesium, calcium, potassium, sodium) at levels significantly higher than surface water or filtered tap water. These mineral compounds support skin barrier enzyme function and skin cell metabolism in ways that pure water cannot — the cleanser's mineral-rich base is functionally different from a standard foam cleanser.

How the Dokdo Cleanser avoids barrier stripping

Standard foam cleansers rely on sodium lauryl sulfate or similar anionic surfactants that create a dense lather but also strip the skin's natural lipid layer more aggressively than necessary for basic cleanliness. ROUND LAB 1025 Dokdo Cleanser 150ml uses milder surfactant alternatives alongside the mineral water base, producing a moderate lather that removes sebum, environmental residue and water-soluble product layers without disrupting the ceramide and fatty acid components of the barrier. The result is skin that feels clean without the "squeaky" tightness that indicates barrier disruption.

Morning versus evening use of the Dokdo Cleanser

The Dokdo Cleanser works in both morning and evening contexts. In the morning, it removes overnight sebum and the small amount of skincare residue that persists through the night without the abrasion of mechanical exfoliation. In the evening, it serves as the second step of a double cleanse after an oil cleanser has removed SPF and makeup — its role as the water-based step that removes the emulsified oil and remaining water-soluble residue. The 150ml size is sufficient for approximately two months of twice-daily use, making it a practical everyday cleanser rather than a luxury that must be rationed.

Integrating the cleanser into a ROUND LAB system

The Dokdo Cleanser opens a ROUND LAB routine that proceeds through the Camellia PDRN Milky Toner, then to the appropriate treatment product (Camellia Firming Ampoule in the evening, Camellia Firming Sun Serum in the morning) and closes with the Birch Juice moisturizer or cream. Every step in this sequence uses ROUND LAB's signature mineral and botanical actives, creating a consistent ingredient environment where each product builds on the last rather than introducing a new active family that requires its own compatibility assessment.

Why cleanser selection matters more than most people acknowledge

The cleanser step is the shortest contact-time product in most routines (60 to 90 seconds) and the one most often selected based on feel rather than formulation. However, its cumulative impact on the skin barrier — applied twice daily, 365 days per year — is greater than any serum or moisturizer used at lower frequency. A cleanser that strips the barrier two times daily gradually reduces barrier integrity over months, requiring progressively more repair-focused products to compensate. The Dokdo Cleanser's mineral-supportive base represents a different philosophy: the cleanser strengthens even as it removes, so the rest of the routine starts from a stronger foundation.
