UVA vs. UVB protection: which labels matter

SPF primarily measures protection against UVB-related sunburn. For skin aging and deeper-penetrating radiation, however, UVA matters. In Europe, a product is only considered balanced if UVA protection reaches at least one third of the stated SPF. You can recognise this by the UVA circle symbol on the packaging. In Korea and Japan, UVA protection is usually shown with the PA system, which is based on the PPD value. PA++++ stands for very high UVA protection. In the US, the label Broad Spectrum signals that a minimum level of UVA protection is present, based on critical wavelength.

Remember this: the combination of a high SPF and clearly stated UVA protection is the best indicator that a product truly offers broad-spectrum protection. A PA++++ in Korea or Japan generally corresponds in practice to a high PPD value that compares well with European requirements. For your own risk assessment, origin matters less than whether these claims are transparent and easy to verify. For more background, see Difference between UVA and UVB in sun protection.

Test methods in the EU, Korea and Japan explained briefly

In the EU, SPF is determined in vivo (ISO 24444), while UVA protection is generally measured in vitro using the transmission method (ISO 24443). In addition, the Colipa criterion ensures that UVA-PF is at least one third of SPF. In Korea and Japan, procedures follow similar internationally recognised standards. The PA value is based on the PPD concept and derived through standardised methods. The result: even if the labels look different, all systems aim to provide reproducible, comparable statements about UVB and UVA protection. What matters is that you look for reliable signs such as the UVA circle or PA++++ and, for official imports, compliance with the EU cosmetics regulation.

UV cameras and smartphone tests: the limits of the evidence

UV-camera clips are impressive, but they are not lab tests. What they show depends on the light source, camera sensor, filters, shine, and application technique. Different filter types also behave differently in front of a camera: organic filters often look darker, while mineral filters can appear lighter because of scattering. Tints, primers, skin shine, and even image contrast can change the result. So the rule is simple: use such images as illustrations at most, not as proof. For your buying decision, standardised lab values such as SPF, the UVA circle, PA rating, and reliable product information are far more meaningful than influencer comparisons using phone gadgets.

Filter types and why comparisons are often misleading

Modern formulas combine several filters to optimise UVB and UVA coverage. Organic filters such as Uvinul A Plus, Tinosorb S or Uvinul T 150 offer strong protection that often feels very elegant with little white cast. Mineral filters such as titanium dioxide and zinc oxide reflect and scatter light, are often well tolerated, but can be more visible on skin. In UV photos, these different systems can look very different without the real protection profile being worse. What matters is the overall formulation: filter mix, stabilisation, film formers, and your skin preferences.

How to buy and use sunscreen safely

Even the best formula only protects if you apply enough and apply it correctly. And serious labelling helps you recognise real quality.

• Amount: For face and neck, about 2 mg per cm² — in practice this usually equals the 3-finger rule for sunscreen.
• Reapplication: Reapply every 2 hours, and again after sweating, swimming, or towel-drying — reapplying sunscreen over makeup is possible.
• UVA recognition: In the EU, look for the UVA circle. In Korea and Japan, look for PA ratings — ideally PA++++.
• Water resistance: Only rely on it when it is explicitly declared.
• Shelf life: Check the open-jar symbol, avoid overheating, and respect the expiry date.
• Reliable source: Buy from official retailers so labelling and storage are correct.
• Sensitive skin? Prefer low-alcohol, fragrance-free products and patch-test on a small area first.

For very sensitive skin, mineral options are often the first choice, for example AXIS-Y Mineral Sunscreen — suitable for sensitive skin.

FAQ

Are Korean sunscreens still safe?

Yes, if they are labelled correctly and you buy from reliable retailers. Look for high SPF plus clearly stated UVA protection — in the EU that means the UVA circle, in Korea and Japan PA++++. Some incidents in the past led to greater transparency, and many brands now publish additional test information. Regardless of origin, amount, reapplication, and shelf life remain crucial. For easily irritated skin, soothing Heartleaf-based formulas such as ANUA sunscreen can be a good fit.

Are Korean sunscreens better than European ones?

Not automatically better or worse. Asian formulas often stand out for lighter textures and modern filters, while European products are known for strict UVA requirements. What matters is what works for you: high SPF, reliable UVA protection, and a texture you will use generously every day. If you have especially sensitive skin, mild Japanese formulas can be an excellent option. More on that here: Is Korean sunscreen better than European?

Which Korean sunscreen is good?

Use clear criteria instead of hype: SPF 50 or 50+, PA++++ or, in the EU, the UVA circle; low-alcohol and fragrance-free formulas for sensitive skin; and a texture that makes generous application easy. Popular options include ISNTREE sunscreen — lightweight filters with good tolerability.

Fluff-free conclusion: you can judge whether Korean sunscreen is safe by looking at SPF, the UVA label, and reliable points of sale.
