Zinc Oxide

Zinc is an essential mineral widely used in cosmedical skincare for its barrier-supportive, healing and repairing qualities. In O COSMEDICS formulations, zinc appears in SPF products in the form of zinc oxide, the approved mineral filter responsible for providing broad-spectrum UV protection. As a physical sunscreen active, zinc oxide works by forming a uniform, protective layer on the surface of the skin that reflects and scatters UV radiation, helping prevent UV-induced skin damage and premature visible aging.

Beyond its UV function, zinc helps maintain a calm, balanced skin. It supports a healthy barrier, contributes to visible redness reduction and assists in regulating oil flow. These qualities make zinc valuable for skins that experience environmental exposure, sensitivity or oil imbalance.

Benefits For The Skin

Reflects UV rays providing broad-spectrum protection when used in SPF formulations

Supports barrier function by helping maintain a protective surface layer

Helps calm the look of redness and visible irritation

Assists in balancing sebum levels for clearer looking skin

Encourages skin healing to repair damage induced by external aggressors

Reduces inflammation and the appearance of breakouts

Form, Stability & Delivery

Zinc oxide is a naturally stable, inorganic mineral filter that maintains its integrity when exposed to heat, light and air, making it ideal for daily SPF protection. Because it does not oxidise, degrade or lose effectiveness when illuminated by UV it delivers consistent broad-spectrum performance throughout wear.

In O COSMEDICS formulations, zinc oxide is micronized and finely dispersed to ensure even coverage and a smooth finish. Its physical mode of action allows it to sit on the surface of the skin as a protective film supporting both barrier function and visible skin health.

How Zinc Oxide Works - Made Simple

1. Broad-Spectrum UV Protection
As zinc oxide in SPF formulas it reflects and scatters UVA and UVB radiation at the skin’s surface to provide broad-spectrum protection.

2. Barrier Strength & Support
Zinc helps maintain a protective barrier environment that supports hydration retention and resilience.

3. Calms Visible Redness
Its healing qualities help reduce the look of irritation

4. Surface Oil Balance
Zinc supports balanced sebum levels helping maintain clearer skin.

5. Environmental Defence
With antioxidant activity, zinc contributes to protection against environmental aggressors that impact visible skin health.
