What does SPF mean? Quick guide to PA++++, UVA/UVB
SPF (Sun Protection Factor) primarily indicates protection against UVB rays, which cause sunburn and reddening. PA, on the other hand, represents protection against UVA rays, which can lead to dark spots, dullness, and photoaging.
For daily commuting, SPF30 is generally sufficient; for extended outdoor activities, consider a higher protection factor.
Physical vs. Chemical Sunscreen: What's the difference? Summer sunscreen recommendations?
- Physical sunscreens primarily reflect UV rays using mineral ingredients, commonly Zinc Oxide and Titanium Dioxide. They are generally gentler and suitable for sensitive skin and pregnant women.
- Chemical sunscreens absorb UV rays and then convert and release them. Their texture is usually lighter and more transparent, but some skin types may experience irritation.
In recent years, many physical mineral sunscreens have improved to address issues of thickness and white cast, making them more suitable for daily use in Hong Kong's humid climate.
For example, Herbs’Oil's PINK CLOUD Hydrating Mineral Sunscreen SPF30 with Sea Fennel uses a dual mineral UV filter system with Zinc Oxide and Titanium Dioxide to effectively block UVA/UVB. It also contains ingredients such as Mediterranean sea fennel extract, Vitamin B3, Vitamin B5, green tea, and sea grapes, providing hydration, repair, and antioxidant benefits.
The brand's unique "PINK CLOUD Lightweight Adherence Technology" ensures that the sunscreen particles are finer and more adherent, reducing the thick and white cast often associated with traditional mineral sunscreens. The formula is alcohol-free and fragrance-free, making it safe for sensitive skin.
This product combines sun protection, hydration, soothing, and barrier repair functions, making it particularly suitable for daily skincare in hot and humid climates.
Sun cream, sun lotion, sun oil: How to choose?
| Type | Texture Properties |
|---|---|
| Sun cream | Richer texture, suitable for dry skin |
| Sun lotion | Lighter texture, suitable for daily use and summer |
| Sun oil | Usually more waterproof, suitable for outdoor activities |
Summer Sun Protection Tips for Different Skin Types
| Skin Type | Key Selection Points for Summer Sunscreen |
|---|---|
| Sensitive Skin | It is recommended to choose mineral sunscreens with simple ingredients, no alcohol, and no fragrance, as they are gentler and more stable for the skin. |
| Oily Skin | Prioritize lightweight, non-sticky products with good spreadability to reduce a stuffy feeling. |
| Dry Skin | It is recommended to choose sunscreens that also have moisturizing and repairing effects to help reduce dryness and tightness. |
How much sunscreen to apply? How often to reapply?
Recommendations:
- Apply 15 minutes before sun exposure
- Use about two finger-lengths for the face
- Reapply every 2 hours
- Reapply immediately after sweating or swimming
Sunscreen should also be the last step in your morning skincare routine.
