Korean Sunscreen Guide 2025: SPF & PA Explained, Skin Type Tips, and Application Rules
Korean Sunscreen SPF/PA Complete Guide (2025 Update)
One daily application can change your skin’s future. Choose the right sunscreen for your lifestyle.
Understanding SPF and PA
SPF measures UVB protection (sunburn), while PA indicates UVA protection (photoaging). SPF relates to how long you can stay in the sun without burning, and PA uses plus signs to show UVA protection. For daily outdoor activities, SPF 30–50 and PA+++ or higher is a practical target.
Chemical vs Mineral Filters
Chemical filters feel lighter and layer well under makeup. Mineral filters are often preferred by sensitive skin but can leave a white cast—pair with a hydrating base and thin layers. Hybrid formulas balance feel and protection.
How Much and How Often?
- Amount: About 2mg/cm² for the face. A practical shortcut is the 3‑finger rule.
- Reapplication: Every 2–3 hours, especially after sweating, water, or mask use.
- Coverage traps: Don’t forget ears, neck, hands, hairline, and the back of the neck.
Skin Type Recommendations
| Skin Type | Recommended Formula | Key Points |
|---|---|---|
| Oily/Acne‑prone | Gel/Fluid, fragrance‑free | Non‑comedogenic, matte or natural finish |
| Dry | Cream/Lotion with ceramides or squalane | Long‑lasting hydration, minimize pilling |
| Sensitive | Mineral‑based or hybrid | Low alcohol/fragrance, thin layered application |
Choosing by Situation
- Indoor office: Lightweight chemical filter + one midday reapplication.
- Outdoor all‑day: SPF50+/PA++++, sweat‑resistant, plus hat and sunglasses.
- Sports/Water: Water/sweat‑resistant; reapply after towel drying.
FAQs
When should I apply sunscreen before makeup?
As the last skincare step; wait 2–3 minutes before primer or foundation to reduce pilling.
Is a sunscreen stick enough?
Coverage can be uneven. Pair with liquid/cream sunscreen or apply multiple overlapping passes in different directions.
How do I reduce white cast?
Don’t cut the total amount; apply thin layers twice and avoid mixing sunscreen directly with makeup.
