Our SPF and UV Testing Services

We offer a complete range of SPF and UV testing services designed to support your cosmetic product claims.

SPF In Vivo Testing - ISO 24444:2019

SPF In Vivo Testing determines the Sun Protection Factor (SPF) of sunscreen products through controlled testing on human skin. This method evaluates the effectiveness of a formulation in protecting against UVB-induced erythema and supports the substantiation of SPF claims for sunscreens and cosmetic products.

SPF In Vitro Testing - ISO 23675:2024 Double Plate Method

Our SPF In Vitro Testing service using the ISO 23675:2024 Double Plate Method evaluates the sun protection performance of sunscreen formulations through a standardised laboratory procedure. The method uses two types of PMMA plates to assess sunscreen film characteristics and UV transmission, supporting the determination of in vitro SPF.

The SPF Double Plate Method provides a standardised approach to evaluating sunscreen performance and supports cosmetic manufacturers in the development, assessment and optimisation of sun protection formulations.

UVA In Vitro Testing - ISO 24443:2021

UVA In Vitro Testing evaluates the UVA protection performance of sunscreen formulations using spectrophotometric measurements. In accordance with ISO 24443:2021, the method supports the determination of UVA Protection Factor (UVA-PF), critical wavelength and the UVA-to-UVB protection ratio.

This laboratory testing method provides valuable data for assessing the broad-spectrum protection performance of sunscreen products and supporting the substantiation of UVA-related product claims.

UVA In Vivo Testing - PPD Method, ISO 24442:2022

UVA in vivo testing service evaluates UVA protection using the Persistent Pigment Darkening (PPD) method in accordance with ISO 24442:2022. This method determines the UVA Protection Factor (UVA-PF) by assessing the skin’s response to UVA radiation under controlled conditions.

UVA testing supports the evaluation of broad-spectrum sun protection and helps substantiate UVA protection claims for sunscreen formulations and other cosmetic products designed to protect the skin against UVA radiation.

Sunscreen Water Resistance Testing - ISO 16217:2020 and ISO 18861:2020 / FDA Guidelines

Sunscreen water resistance testing services evaluate the ability of sunscreen products to maintain their sun protection performance following water immersion. Testing can support the assessment and substantiation of water resistance claims in accordance with applicable testing standards and, where relevant, regulatory guidance.

Water resistance testing is particularly important for sunscreen products intended for swimming, outdoor activities and other situations involving water exposure. The results help manufacturers evaluate product performance and support appropriate water resistance labelling.

Additional Cosmetic Testing Services

In addition to SPF and UV protection testing, we offer specialised testing services to support the comprehensive evaluation of sunscreen products and cosmetic formulations. Our additional services include:

  • Sweat resistance testing – evaluation of sunscreen performance under relevant perspiration-related conditions.
  • Wash-off efficacy testing – assessment of product removal and the persistence of relevant product performance following washing.
  • Photoallergy testing – assessment of potential photoallergic responses to relevant cosmetic ingredients or formulations.
  • Phototoxicity testing – evaluation of potential adverse skin reactions resulting from the interaction between a substance and light exposure.

These services complement SPF and UVA testing by supporting the assessment of cosmetic product performance and selected aspects of skin safety.

Regulatory Standards and Global Compliance

All SPF and UV tests are conducted under recognized international standards, including:
