Sun protection

1. What is Sunscreen?

Sunscreen is a skincare product that protects your skin from ultraviolet (UV) rays. UV exposure can cause skin aging, pigmentation, and even skin cancer, so consistent protection is key.

2. Types of UV Rays and Their Risks

• UVA: Penetrates deep into the skin, causing aging and wrinkles.
• UVB: Affects the skin surface, causing sunburn and increasing skin cancer risk.

3. Understanding SPF and PA Ratings

• SPF (Sun Protection Factor): Measures protection against UVB rays. For example, SPF 30 means you can stay in the sun 30 times longer before burning.
• PA (Protection Grade of UVA): Measures UVA protection. More plus signs (PA+, PA++, PA+++) mean stronger protection.

4. How to Apply Sunscreen Properly

• Use enough: About 2 mg/cm² of skin, roughly a teaspoon for your face.
• Apply 20-30 minutes before going outside so it absorbs well.
• Reapply every 2-3 hours, especially after sweating or swimming.

5. Choosing Sunscreen by Skin Type

• Sensitive skin: Fragrance-free, alcohol-free, physical blockers like titanium dioxide or zinc oxide.
• Oily skin: Lightweight, gel-based formulas.
• Dry skin: Sunscreens with moisturizing ingredients.

6. Precautions When Using Sunscreen

• Avoid getting it in your eyes.
• Check expiration dates and storage conditions.
• Stop use and consult a dermatologist if irritation occurs.

Consistent use of sunscreen is the first step to healthy skin. Find the right product for you and use it properly to keep your skin safe!

1. Which sunscreens are best for swimming or sports (i.e., water-resistant)?

According to the U.S. FDA, sunscreens labeled \"water-resistant\" must maintain their SPF after 40 or 80 minutes of water exposure. These products are ideal for swimming, exercising, or sweating. Popular options include:

• Neutrogena Sport Face Oil-Free Lotion SPF 70
• Coppertone Sport SPF 50 Lotion
• Banana Boat Ultra Sport SPF 50

Remember: no sunscreen is \"waterproof.\" Always reapply every 40–80 minutes when in water or sweating.

2. What are the safest sunscreens for sensitive skin?

Sensitive skin users should opt for mineral (physical) sunscreens containing zinc oxide or titanium dioxide, which are less likely to cause irritation. Look for \"fragrance-free,\" \"hypoallergenic,\" and \"alcohol-free\" labels.

• La Roche-Posay Anthelios Mineral SPF 50
• CeraVe Hydrating Mineral Sunscreen SPF 30/50
• Aveeno Positively Mineral SPF 50

3. What does SPF really mean, and how much do I need?

SPF (Sun Protection Factor) measures UVB protection. SPF 30 blocks ~97% of UVB rays, SPF 50 about 98%, and SPF 100 about 99%. The American Academy of Dermatology (AAD) recommends SPF 30 or higher for daily use.

Choose higher SPF (50–100) for outdoor activities, especially at the beach or during intense sun exposure.

4. Are mineral (physical) sunscreens better than chemical ones?

Mineral sunscreens sit on the skin and reflect UV rays. They’re ideal for sensitive or acne-prone skin.

Chemical sunscreens absorb UV rays and convert them into heat. They tend to be lighter in texture and more water-resistant.

Best choice? It depends on your skin type and preferences. Both are effective when used properly.

5. Which sunscreens are reef-safe and eco-friendly?

\"Reef-safe\" sunscreens exclude harmful ingredients like oxybenzone and octinoxate, which damage coral reefs. Hawaii and some coastal regions have banned these ingredients.

• Thinksport SPF 50+
• Raw Elements Face + Body SPF 30
• Blue Lizard Australian Sunscreen (Sensitive)

---

6. Can I wear sunscreen under makeup? Will it still work?

Yes. Apply sunscreen as the last step of your skincare routine, before makeup. Wait 1–2 minutes for it to set. For touch-ups, consider a powder sunscreen or setting spray with SPF.

Makeup with SPF is helpful but should not replace a dedicated sunscreen layer.

---

7. How often should I reapply sunscreen, and how much should I use?

Use at least 1 ounce (a shot glass full) for the body and 1/4 to 1/2 teaspoon for the face. Reapply:

• Every 2 hours, even on cloudy days.
• Immediately after swimming, sweating, or towel drying.

Inadequate application is the #1 reason sunscreen fails.

---

8. What sunscreens are approved or recommended by dermatologists or the FDA?

The FDA does not \"approve\" sunscreens in the way it approves drugs, but it regulates them. Look for \"Broad Spectrum\" and \"SPF 30 or higher\" labels.

• EltaMD UV Clear SPF 46
• Neutrogena Ultra Sheer Dry-Touch SPF 55
• La Roche-Posay Anthelios SPF 60

---

9. Is spray sunscreen effective and safe to use?

Yes, but technique matters. Spray liberally until an even sheen appears, then rub it in. Avoid inhaling the spray—never apply directly to the face; spray onto hands first, then apply.

Great for quick reapplication, but lotion sunscreens are more foolproof for full coverage.

10. Can kids and babies use regular sunscreen, or do they need special formulas?

For babies under 6 months, avoid direct sun exposure. Use shade and protective clothing instead.

For kids over 6 months, use mineral sunscreens with zinc oxide or titanium dioxide. Choose fragrance-free, gentle formulas:

• Blue Lizard Baby SPF 50+
• Thinkbaby Safe Sunscreen SPF 50+
• Aveeno Baby Continuous Protection SPF 50
