What Is SPF and Why SPF Testing Matters

Sun Protection Factor (SPF) indicates a product’s ability to protect skin against UVB radiation, which causes sunburn and contributes to skin cancer.

SPF testing confirms that sunscreens and cosmetics offer the declared level of UVB and UVA protection.
While SPF measures UVB defense, UVA Protection Factor (UVA-PF) evaluates protection against photoaging, pigmentation, and DNA damage.

Our laboratory performs in vivo and in vitro SPF testing according to international standards:

ISO 24444:2019 – In vivo SPF determination
EN ISO 23675:2024 – In vitro SPF (Double Plate Method)

These validated methods ensure scientifically reliable and globally recognized results.

2. In Vivo UVA Testing – PPD Method (ISO 24442:2022)

Measures UVA protection using the Persistent Pigment Darkening (PPD) method.
Essential for broad-spectrum and anti-photoaging claims.

3. In Vitro UVA-PF Testing (ISO 24443:2021)

Assesses UVA Protection Factor (UVA-PF), critical wavelength, and UVA:UVB ratio using UV spectrophotometry.
Supports UVA protection and broad-spectrum product claims.

4. Water Resistance Testing (ISO 16217:2020, ISO 18861:2020 / FDA Guidelines)

Evaluates whether sunscreen products maintain their SPF after water immersion or sweating.
