Round Lab 1025 Dokdo Sunscreen SPF 50+ PA++++ — Lightweight Korean Sunscreen for Sensitive & Acne-Prone Skin

The Korean Sunscreen That Protects, Hydrates & Never Leaves a White Cast

Meet the Round Lab 1025 Dokdo Sunscreen SPF 50+ PA++++ — the mineral-rich, essence-like Korean sunscreen that delivers powerful broad-spectrum protection while simultaneously hydrating, calming, and balancing the skin. Formulated with Ulleungdo Island Deep Sea Water, Triple Hyaluronic Acid, patented ACZERO™ (7 plant extracts), Niacinamide, and five next-generation UV filters, this is the go-to daily sunscreen for anyone with sensitive, oily, combination, or acne-prone skin who refuses to compromise on either protection or finish.

Inspired by the pristine, mineral-rich deep sea water sourced 1,025 metres below the surface of the East Sea near Ulleungdo Island and the Dokdo Islets — one of South Korea's most protected natural environments — this sunscreen delivers something rare: maximum sun protection in a formula that actually improves your skin over time. No white cast. No greasy residue. No pilling under makeup. Just smooth, healthy, protected skin from the first application.

Why You'll Love It

☀️ SPF 50+ PA++++ — Maximum Broad-Spectrum Protection
Clinically validated to deliver the highest levels of both UVB and UVA protection. PA++++ indicates a UVA protection factor of 16 or above — meaning both burning rays and the deeper, ageing UVA rays are comprehensively blocked. Five advanced, next-generation UV filters work in concert to achieve this protection level while maintaining a lightweight, skin-friendly formula.

🌊 Ulleungdo Deep Sea Water — Mineral-Rich Hydration at the Core
The hero ingredient of the entire 1025 Dokdo range. Sourced from 1,025 metres below the surface of the East Sea near the Ulleungdo and Dokdo Islands — one of South Korea's most pristine and protected natural environments — this mineral-rich deep sea water is extraordinarily clean and rich in naturally occurring minerals that balance the skin's moisture and oil levels, leaving the complexion clear, calm, and genuinely nourished throughout the day.

💧 Triple Hyaluronic Acid — Hydration at Every Skin Layer
Three molecular weights of Hyaluronic Acid — Sodium Hyaluronate (high molecular weight), Sodium Acetylated Hyaluronate (medium), and Hydrolyzed Hyaluronic Acid (low molecular weight) — deliver moisture simultaneously at the skin's surface, mid-layers, and deeper dermal levels. The result is plump, comfortable, visibly well-hydrated skin throughout the day — even under SPF.

🌿 Patented ACZERO™ — 7 Plant Extracts for Sebum Control & Soothing
ACZERO™ is Round Lab's exclusive patented complex comprising seven plant-derived extracts including White Willow Bark Extract, Green Tea Extract, Centella Asiatica Leaf Extract, Pine Leaf Extract, Bergamot Leaf Extract, Coffee Bean Extract, and Okamura Horseradish Extract. Together they actively regulate excess sebum, minimise shine, soothe irritation, and provide antioxidant protection — making this sunscreen particularly well-suited to oily, combination, and acne-prone skin types.

✨ Niacinamide — Brightens While It Protects
A multitasking Vitamin B3 derivative that reduces the appearance of dark spots and hyperpigmentation, regulates sebum production, minimises pore appearance, and strengthens the skin barrier — delivering meaningful skincare benefits with every morning application, not just UV protection.

🌱 Reef Safe Formula — Kind to Your Skin & the Ocean
Round Lab's 1025 Dokdo Sunscreen is certified reef safe, containing no oxybenzone or octinoxate — the two UV filters most commonly linked to coral reef damage. Conscious sun protection for skin and sea alike.

🧴 Essence-Like Texture — No White Cast, No Pilling
Despite its high SPF rating, this sunscreen applies like a lightweight essence-lotion hybrid — spreading effortlessly, absorbing quickly, and leaving no white cast, no sticky finish, and no residue that would cause makeup to pill or separate. A genuine daily-wear sunscreen that works as the last step of your skincare and the first step of your makeup routine.

🫧 Easy-Rinse Formula — Removes with Your First Cleanse
Unlike many high-SPF sunscreens that require a dedicated makeup remover or oil cleanser to remove fully, the 1025 Dokdo Sunscreen is formulated to rinse away completely with a standard water-based cleanser on the first wash — making it ideal for sensitive skin types that struggle with heavy-duty double cleansing.

🔬 Non-Comedogenic & Clinically Tested
Completed a non-comedogenic human application test — clinically confirmed not to clog pores. Dermatologist-tested and suitable for acne-prone and sensitive skin.

Key Ingredients — What They Do

Ulleungdo Island Deep Sea Water
Sourced from 1,025 metres below the East Sea near the Dokdo Islets — one of the world's most protected and pristine marine environments. This mineral-dense sea water is naturally rich in magnesium, calcium, potassium, and trace minerals that help balance the skin's oil-moisture ratio, maintain a healthy complexion, and deliver genuine hydration that standard filtered water cannot replicate.

Triple Hyaluronic Acid (Sodium Hyaluronate + Sodium Acetylated Hyaluronate + Hydrolyzed Hyaluronic Acid)
Three complementary molecular weights of Hyaluronic Acid target hydration at different skin depths simultaneously. High molecular weight Sodium Hyaluronate sits on the surface to reduce moisture evaporation and restore the skin's protective film. Medium molecular weight Sodium Acetylated Hyaluronate — one of the most advanced HA derivatives available — penetrates slightly deeper to deliver lasting, plumping hydration. Low molecular weight Hydrolyzed Hyaluronic Acid permeates deepest, replenishing moisture from within and visibly reducing the appearance of fine lines.

ACZERO™ — Patented 7-Plant Extract Complex
Round Lab's proprietary blend of White Willow Bark Extract, Green Tea Extract, Centella Asiatica Leaf Extract, Pine Leaf Extract, Bergamot Leaf Extract, Coffee Bean Extract, and Okamura Horseradish Extract. This patent-protected complex was developed to address the specific needs of oily and acne-prone skin: controlling excess sebum, minimising breakouts, soothing redness and irritation, and providing powerful antioxidant defence against environmental stressors — all without compromising sun protection efficacy.

Niacinamide (Vitamin B3)
A clinically proven multi-tasking active that brightens uneven skin tone by inhibiting melanin transfer, minimises the appearance of enlarged pores, regulates sebum production, eases redness from inflammation and acne, and strengthens the skin barrier with continued use. Its inclusion in a daily sunscreen means your skin benefits from its brightening and balancing effects every single morning.

Panthenol (Provitamin B5)
A deeply penetrating humectant that attracts and binds moisture into the skin, soothes sensitivity, and supports barrier repair. Panthenol counteracts any potential dryness introduced during the day and ensures the skin remains comfortable and balanced under SPF all day long.

Allantoin
A well-researched skin-calming and cell-renewing ingredient that accelerates barrier recovery, soothes irritation, and promotes a smoother skin texture over time. Its inclusion makes this sunscreen particularly compatible with reactive and sensitised skin.

Adenosine
A clinically proven anti-ageing ingredient that improves skin firmness, smooths the appearance of fine lines and wrinkles, and supports a more youthful-looking complexion with consistent daily use.

Betaine
A naturally derived osmolyte that acts as a humectant and anti-irritant. Betaine helps the skin maintain moisture balance under environmental stressors, reduces the sensation of tightness, and contributes to the comfortable, non-drying finish that sets this sunscreen apart.

Tocopherol (Vitamin E)
A fat-soluble antioxidant that neutralises free radical damage from UV exposure and environmental pollution, conditions the skin surface, and enhances the photostability of the UV filter system — helping the sunscreen maintain its protective efficacy throughout the day.

Sunscreen Filters — Broad-Spectrum UV Protection

Ethylhexyl Triazone (UVB)
Considered one of the most effective UVB filters available globally. Highly photostable, odourless, and colourless, it provides the highest photostable absorption of any currently available UVB blocker — protecting across the full UVB range (280–320nm) with peak protection at 314nm.

Diethylamino Hydroxybenzoyl Hexyl Benzoate — Uvinul A Plus (UVA)
A next-generation UVA filter that provides deep UVA I protection — guarding against the UV wavelengths responsible for photoageing, DNA damage, and hyperpigmentation. Highly photostable and well tolerated across skin types.

Terephthalylidene Dicamphor Sulfonic Acid — Mexoryl SX (UVA)
A photostable UVA filter effective across the 290–400nm range, developed by L'Oréal. It provides particularly reliable mid-range UVA protection and holds FDA approval for use in select markets, making it one of the more rigorously tested UVA filters in global sun care.

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine — Tinosorb S (Broad Spectrum)
Widely regarded as one of the most effective broad-spectrum UV absorbers available. Tinosorb S covers both UVA and UVB with exceptional photostability and holds an outstanding safety profile. At maximum permitted EU concentration it delivers the highest SPF contribution of any single filter — and it actively prevents photodegradation of other UV filters in the formula, keeping the entire system stable under prolonged sun exposure.

Polysilicone-15 (UVB)
A silicone-encapsulated UVB filter that provides targeted protection in the 290–320nm range. Its silicone backbone contributes to the formula's elegant, non-greasy skin feel while offering additional photostability to the overall UV filter system.

How to Use

1. Step 1 — Apply as the final step of your morning skincare routine, after toner, serum, and moisturiser.
2. Step 2 — Dispense a generous amount (approximately ¼ teaspoon for the face) and spread evenly across the entire face and neck using light, upward strokes.
3. Step 3 — Allow to absorb fully before applying makeup. The essence-like texture absorbs quickly and does not require a long wait time.
4. Step 4 — Reapply every 2 hours during prolonged outdoor exposure, or after sweating or swimming.

💡 Pro Tip: For oily or combination skin, pair with the Round Lab 1025 Dokdo Toner before application to maximise the mineral balancing benefits of the Ulleungdo Deep Sea Water throughout your entire routine. For dry skin types, layer over a Hyaluronic Acid serum to amplify the triple HA hydration effect.
