Just seen on the season finale of Die Höhle der Löwen on VOX. We built sun matters because sunscreen should actually feel good. No sticky residue, no heavy layers - just ultralight, microbiome-certified SPF 50 protection. For your skin. Every single day.

You got the problem?

  • Dehydrated Skin

    Sun and environmental stress can leave skin feeling dry, tight, and unbalanced.

  • Sensitive or Irritated Skin

    Many sunscreens feel heavy or irritating, especially for sensitive or acne-prone skin.

  • UV Stress

    Daily sun exposure can weaken your skin barrier and accelerate premature skin aging.

Application Steps

Light serum SPF50

Apply evenly over skin as the final step in your skincare routine. Follow with makeup if desired. Reapply every two hours and after water exposure.

Barrier Boost Sun Support

Take two capsules daily with plenty of water. For best results, use consistently over a longer period.

Stay Consistent

Continue for at least 28 days to experience the full, clinically proven results — because lasting skin transformation takes time.

The hero ingredients

  • 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.

  • 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.

  • 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.

  • Vitamin D
    Regulates the skin's immune response and supports cellular renewal, ensuring you harness the full restorative benefits of sunlight.

  • Omega-3 & Omega-6 Fatty Acids
    Fortify the skin's protective barrier, seal in moisture, and reduce inflammation — preserving long-term skin health from within.

  • Vitamin B3 (Niacinamide)
    Reinforces barrier function, enhances moisture retention, and visibly reduces redness and sensitivity for a calm, even-toned complexion.

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.
