Understanding Sun Protection

Understanding sun protection is no easy task. With so many products and SPF levels available, it can be a bit overwhelming to choose the right one. Don’t worry—we’ve got you covered. Let’s explore what SPF levels mean, the difference between physical and chemical SPF, and why daily sun protection is essential, especially in sunny Southern California.

What Does SPF Mean?

Do you want clear skin?

SPF stands for Sun Protection Factor, and it indicates how well a sunscreen can protect your skin from harmful UVB rays, which are the main cause of sunburn and contribute to skin cancer. Here’s a quick breakdown of what different SPF levels mean:

  • SPF 15: Blocks about 93% of UVB rays.
  • SPF 30: Blocks about 97% of UVB rays.
  • SPF 50: Blocks about 98% of UVB rays.

While higher SPF numbers offer slightly more protection, no sunscreen can block 100% of UVB rays. The key is to apply it generously and reapply regularly.

Physical vs. Chemical SPF: What’s the Difference?

When it comes to sunscreens, there are two main types: physical (mineral) and chemical. Here’s what you need to know:

Physical (Mineral) SPF:

  • Ingredients: Typically contain zinc oxide or titanium dioxide.
  • How it Works: Forms a barrier on the skin’s surface that reflects and scatters UV rays.
  • Benefits:
    • Works immediately upon application.
    • Less likely to cause skin irritation.
    • Often considered better for sensitive skin.
    • Broad-spectrum protection against both UVA and UVB rays.
  • Products We Offer:

Chemical SPF:

  • Ingredients: Common ones include avobenzone, octinoxate, and oxybenzone.
  • How it Works: Absorbs UV rays and converts them into heat, which is then released from the skin.
  • Benefits:
    • Tends to be thinner and easier to apply without leaving a white cast.
    • Often more water-resistant.
  • Product We Offer:

How Often Should SPF Be Reapplied?

To maintain effective sun protection, it’s crucial to reapply sunscreen regularly:

  • Every Two Hours: Reapply every two hours when spending time outdoors.
  • After Swimming or Sweating: Reapply immediately after swimming, sweating, or towel drying.
  • Daily Use: Even on cloudy days or when indoors, it’s beneficial to apply sunscreen, as UV rays can penetrate windows and clouds.

Why Daily SPF is Essential, Especially in Southern California

Southern California is famous for its sunny weather, which is wonderful but also means increased UV exposure. Here’s why daily SPF use is crucial:

  • Prevent Skin Damage: Daily sun exposure can lead to premature aging, sunspots, and an increased risk of skin cancer.
  • Consistent Protection: Even on cloudy days, up to 80% of UV rays can reach your skin.
  • High UV Index: Southern California often has a high UV index, meaning the intensity of UV radiation is strong, and protection is necessary to prevent damage.

And while you are working on clearing acne, you are using active ingredients, including mandelic and lactic acids, retinols, and benzoyl peroxide. It’s imperative that you protect your skin while using these active ingredients so you don’t experience hyperpigmentation. These ingredients make your skin more sensitive to the sun, increasing the risk of dark spots and uneven skin tone if not adequately protected.


Understanding sun protection and choosing the right sunscreen for your skin type and lifestyle is essential for maintaining healthy skin. Whether you prefer the lightweight feel of a chemical sunscreen like our Sun Guard SPF 30 or the immediate protection of a physical sunscreen such as UV Shade or Sol RX, it’s crucial to make SPF a daily habit. Reapply regularly, and don’t forget to protect your skin, especially during those sunny Southern California days.

Stay protected, stay beautiful, and enjoy the sun safely!

Cheer to clear!
