Ingredient breakdown

INGREDIENTS

Betula Platyphylla Japonica Juice (Birch Juice) 1,425ppmProven

Sap from silver birch trees harvested in Inje County, South Korea. Naturally rich in amino acids, minerals (calcium, magnesium, potassium), and vitamins that provide deep hydration and antioxidant protection.

  • Hydration: Contains natural sugars and minerals that form a moisture barrier on the skin surface
  • Anti-inflammatory: Betulin compounds in birch sap have documented soothing and anti-redness properties
  • Antioxidant: Rich in vitamin C and polyphenols that protect against environmental free radical damage
Unique to the Round Lab Birch line — sourced from a specific Korean region known for high-quality birch sap

Quad UV Filter Complex 4 FiltersProven

Four next-generation chemical UV filters approved in Europe and Asia deliver exceptional photostable protection across the full UV spectrum.

  • Uvinul A Plus (DHHB): Full UVA range protection (320–400nm), peak at 354nm. Photostable and up to 10% concentration
  • Uvinul T 150 (Ethylhexyl Triazone): Strong UVB absorption. Highly photostable even after extended sun exposure
  • Tinosorb M (Bisoctrizole): Hybrid UVA+UVB filter that both absorbs and reflects UV rays for broad coverage
  • Iscotrizinol: UVB + partial UVA protection. Ultra-photostable at low concentrations, oil-soluble for easy removal

  • Anti-aging: Shown to reduce fine lines and wrinkles at 4-5% concentration in clinical studies

Hyaluronic Acid Complex Dual-weightProven

Both Sodium Hyaluronate and Hyaluronic Acid are included to deliver hydration at multiple skin depths.

  • Sodium Hyaluronate: Smaller molecule that penetrates deeper for long-lasting internal hydration
  • Hyaluronic Acid: Larger molecule that sits on the surface holding up to 1,000x its weight in water
  • Synergy: Dual-weight approach provides both immediate plumping and sustained moisture throughout the day

Soothing Botanical ComplexPromising

A blend of plant-derived calming agents that work together to reduce irritation and reinforce skin resilience.

  • Allantoin: Plant-derived skin protectant that promotes cell regeneration and soothes irritated skin
  • Dipotassium Glycyrrhizate (Licorice Root): Anti-inflammatory humectant that calms redness and provides moisture
  • Portulaca Oleracea (Purslane): Rich in omega-3 fatty acids and antioxidants for soothing inflamed skin
  • Artemisia Annua: Traditional Korean botanical with antioxidant and anti-inflammatory properties

AdenosineProven

A Korean MFDS-approved anti-wrinkle active that stimulates collagen production and helps improve skin elasticity over time.

How to use

HOW TO USE
1

Dispense Generously

Squeeze approximately 2–3 finger lengths of product. For proper SPF protection, you need about 1/4 teaspoon for the face alone.

2

Dot & Spread Evenly

Place dots on forehead, cheeks, nose, and chin. Gently spread and pat the sunscreen across your entire face, neck, and ears. Avoid rubbing too aggressively.

3

Wait Before Makeup

Allow 1–2 minutes for the sunscreen to fully absorb and set before applying primer or makeup. It creates a smooth, non-sticky base.

4

Reapply Every 2 Hours

Reapply generously every 2 hours during outdoor activity, or immediately after swimming, sweating, or towel-drying. This is essential for maintaining full SPF protection.

06

Who is it for?

WHO

Perfect for you if:

  • You want a sunscreen that doubles as a moisturizer
  • You need high SPF without white cast on any skin tone
  • You have dry, dehydrated, or normal skin that craves hydration
  • You wear makeup daily and need a smooth, non-pilling base
  • You prefer next-generation UV filters with high photostability
  • You have sensitive skin and want a dermatologist-tested formula
  • You are pregnant or breastfeeding and need a safe daily SPF

Consider alternatives if:

  • You have very oily skin and need a completely matte finish
  • You are prone to fungal acne (contains potential FA triggers)
  • You need a water-resistant sunscreen for sports or swimming
  • You prefer 100% mineral/physical sunscreen filters only
  • You need a larger size — 50ml runs out fast with daily use
  • You are in the US and want FDA-approved filters (get the UV Lock version instead)

Skin type compatibility

SKIN TYPES
Dry Skin
Excellent

Hydrating enough to replace your moisturizer. Birch juice, glycerin, and dual hyaluronic acid keep dry skin plump and comfortable all day.

Normal Skin
Excellent

Perfect everyday sunscreen. Lightweight, moisturizing, and leaves a naturally healthy-looking finish without feeling heavy.

Combination Skin
Good

Works well across different face zones. May feel slightly dewy on the T-zone by midday — blotting papers help if needed.

Oily Skin
Moderate

The moisturizing finish can feel too dewy for very oily skin. Consider the Round Lab Dokdo sunscreen or a mattifying primer underneath.

Sensitive Skin
Excellent

Dermatest certified, fragrance-free, and loaded with soothing botanicals (allantoin, purslane, artemisia). Ideal for reactive, easily irritated skin.

Acne-Prone Skin
Good

Non-comedogenic with low pore-clogging risk. Niacinamide helps control sebum. However, those with fungal acne should patch test first.

Frequently asked questions

FAQ

Yes, this sunscreen is generally considered safe for use during pregnancy and breastfeeding. It does not contain retinoids, salicylic acid, hydroquinone, or oxybenzone — the ingredients most commonly flagged during pregnancy. The chemical UV filters used (Uvinul A Plus, Uvinul T 150, Tinosorb M, Iscotrizinol) are newer-generation European filters without known reproductive risks. However, always consult your OB-GYN or dermatologist before introducing new skincare products during pregnancy.

Use with caution. This sunscreen contains Coco-Caprylate/Caprate (an ester) and Polyglyceryl-3 Methylglucose Distearate, both of which are flagged as potential malassezia triggers by ingredient databases. If you are actively managing fungal acne, we recommend patch testing first. For a fully fungal acne-safe alternative, consider the Round Lab Birch Juice Moisturizing Sun Stick, which has a cleaner FA profile.

Yes, absolutely. This sunscreen is compatible with all common actives. In fact, wearing SPF 50+ daily is essential when using retinol, vitamin C, or chemical exfoliants (AHA/BHA), as these ingredients increase photosensitivity. Apply your actives first (or use retinol at night), let them absorb, then apply this sunscreen as the final step in your morning routine. Multiple reviewers confirm comfortable wear even after using strong actives the previous evening.

This sunscreen is best suited for dry, normal, and sensitive skin types. Its moisturizing formula with birch juice, dual hyaluronic acid, and glycerin makes it exceptionally hydrating — many users skip their morning moisturizer entirely. Combination skin types will also enjoy it. However, those with very oily skin may find the dewy finish too shiny by midday. For oily skin, consider the Round Lab 1025 Dokdo Sunscreen, which has a more mattifying finish.

UV protection is immediate upon application. Hydration benefits are felt instantly as well. For brightening and skin tone evening from the niacinamide, expect visible improvements in 4–6 weeks of consistent daily use. Long-term sun damage prevention (preventing new dark spots, wrinkles, and premature aging) is an ongoing benefit that compounds over months and years of regular SPF use.

Apply as the very last step of your morning skincare routine, after cleanser, toner, essence, serum, and moisturizer (if needed). Because this sunscreen is highly moisturizing, many users with normal-to-oily skin skip the separate moisturizer step. Wait 1–2 minutes after application before applying makeup or primer. Reapply every 2 hours during sun exposure.

This sunscreen has a very low comedogenic risk, rated 1 out of 5. It has been Dermatest certified and passed non-comedogenic testing. The formula avoids heavy pore-clogging oils and waxes. Numerous reviewers with acne-prone skin report no breakouts even after prolonged daily use. The one potentially comedogenic ingredient (Sorbitan Oleate in some versions) appears very low in the ingredient list.

The Period After Opening (PAO) is 12 months. Once opened, use within 12 months for optimal UV protection efficacy. The packaging also includes a printed expiration date for reference. Store in a cool, dry place away from direct sunlight to maximize shelf life. At the recommended daily usage amount, a single 50ml tube typically lasts 4–6 weeks with once-daily facial application.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: The Round Lab Birch Juice Moisturizing Sunscreen is one of the best moisturizing chemical sunscreens on the market and a K-beauty staple for good reason. Its quad UV filter system delivers excellent photostable broad-spectrum protection, while the birch juice, niacinamide, and dual hyaluronic acid complex provide genuine skincare benefits that go well beyond basic sun protection. The lightweight, no-white-cast formula absorbs beautifully and works as a 2-in-1 moisturizer and sunscreen — perfect for those who want to streamline their morning routine. It loses half a point for its small size relative to its price, its dewy finish that may not suit very oily skin, and potential fungal acne triggers. But for dry, normal, and sensitive skin types seeking premium UV protection with real skincare benefits, this is a top-tier daily sunscreen that lives up to its cult-favorite status.

lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
