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

Remove the cap and discard the protective inner disc. Twist the base to reveal the Serum Stick.

Glide the stick generously and evenly over the face and delicate areas, including around the eyes, ears, nose, lips, and scars.

Reapply throughout the day as needed, especially after sun exposure, swimming, or sweating.

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.

  • Antioxidants
    Our antioxidant blend helps defend the skin against free radical damage caused by UV exposure and pollution. It supports skin resilience, helps protect against visible signs of stress like dullness and premature aging.

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.
