Apply a generous, even layer to your face, neck, and ears. Use the two-finger method as a guide: Dispense two full lines of sunscreen along your index and middle finger for the face. Use as the final step in your morning skincare routine and allow it to fully absorb before applying makeup. For optimal protection, reapply every two hours when exposed to the sun, and after swimming, sweating, or towel-drying.

The hero ingredients

  • Ectoin
    Ectoin is a powerful natural molecule that protects skin cells from environmental stress such as UV light, pollution, and dryness. It helps soothe the skin, reduces irritation, and supports long-lasting hydration.

  • Hyaluronic acid
    Hyaluronic acid is a moisture magnet. It attracts and holds water in the skin, keeping it plump, smooth, and hydrated throughout the day. This helps the skin feel soft and look fresh while preventing dryness from sun exposure.

  • Photobiome™
    Photobiome™, winner of the Best Ingredient Award Korea, helps support the skin’s natural microbiome—the community of good bacteria on your skin. It strengthens the skin’s barrier, helps reduce the stress caused by sunlight, and keeps the skin looking healthy and balanced.

FAQ

While “reef-safe” isn’t officially regulated, Sun Matters formulas follow standards like Hawaii Act 104, which bans oxybenzone and octinoxate. All our products meet these guidelines.
  • UVA: Longer wavelength; contributes to skin aging
  • UVB: Shorter wavelength; causes sunburn

Easy way to remember:

  • A = Aging
  • B = Burning

Sun Matters sunscreens are broad-spectrum, meaning they protect against both.

At Sun Matters we use second-generation modern European UV filters that are specifically selected for their high performance, stability, and skin compatibility. These advanced filters provide strong, broad-spectrum protection against both UVA (aging) and UVB (burning) rays, while being gentler on sensitive skin compared to older sunscreen filters.

We pair these UV filters with skin-supporting ingredients like hydrators and plant-derived components to create formulas that feel lightweight, comfortable, and effective for everyday wear.
