Why Should We Use Sunscreen?
UV rays are not only the main culprit of skin aging but can also cause skin cancer in severe cases. Sunscreen is one of the most effective ways to protect your skin from these UV rays. It’s important to apply it consistently every day!
Physical Sunscreen vs. Chemical Sunscreen: What’s the Difference?
Physical Sunscreen (Mineral Sunscreen):
- Key Ingredients: Zinc oxide, Titanium dioxide
- Mechanism: Forms a protective barrier on the skin’s surface to reflect UV rays.
- Pros:
- Less irritating to the skin, suitable for sensitive skin
- Immediate UV protection
- Cons:
- May leave a white cast
- Can have a somewhat thick texture
Chemical Sunscreen (Organic Sunscreen):
- Key Ingredients: Oxybenzone, Avobenzone, Ethylhexyl Methoxycinnamate, etc.
- Mechanism: Absorbed into the skin, then absorbs UV rays and converts them into heat energy.
- Pros:
- No white cast
- Smooth application and moisturizing
- Cons:
- May cause skin irritation
- Takes time for UV protection to take effect
Ingredient Analysis
Let’s take a closer look at each one. ๐ฌ
Zinc Oxide & Titanium Dioxide:
- EWG Rating: Mostly safe (Grades 1-2)
- Broad-spectrum UV protection (blocks both UVA and UVB)
- Nanoparticle Controversy: There are concerns that smaller particle sizes may penetrate the skin, but many studies to date indicate they are safe.
Oxybenzone & Avobenzone:
- EWG Rating: Oxybenzone is a high-hazard rating (Grades 7-8), Avobenzone is a moderate-hazard rating (Grades 3-4)
- Oxybenzone has controversies regarding potential hormone disruption and damage to marine ecosystems.
- Avobenzone is unstable in sunlight and needs to be formulated with other ingredients to maintain its effectiveness.
Research Findings
According to a study published in the *Journal of the American Academy of Dermatology* in 2021, physical sunscreens based on zinc oxide and titanium dioxide were found to be more suitable for sensitive skin. Clinical trials showed a lower incidence of skin irritation in the group using physical sunscreens.
Which Sunscreen is Right for Your Skin Type?
- Sensitive Skin: Physical sunscreen (Zinc oxide, Titanium dioxide)
- Oily Skin: Chemical sunscreen with a light feel (oil-free products)
- Dry Skin: Chemical sunscreen with a moisturizing feel (products containing hyaluronic acid, ceramides)
- All Skin Types: Products with carefully checked ingredients and that have undergone skin irritation tests
How to Use Sunscreen Properly
- Apply a sufficient amount 30 minutes before going out. (About the size of a 500-won coin)
- Reapply every 2-3 hours.
- Don’t forget to apply it even on cloudy days.
