Sunscreen Testing Lab
SPF (Sun Protection Factor) is a measure of a product’s ability to protect the skin from the harmful effects of ultraviolet (UV) radiation, which can cause skin damage and increase the risk of skin cancer. Testing SPF is essential for evaluating the effectiveness of sunscreens and other sun protection products. Accurate SPF testing helps consumers make informed decisions about their sun protection needs and provides the basis for substantiating product claims regarding UV protection.
At SIMA LABS, we specialize in providing precise and reliable SPF testing services. Our testing process strictly follows the ISO 24443:2021, Colipa, and FDA 2011 guidelines. With our advanced SPF transmittance analyzer, we ensure our testing meets the highest standards of accuracy and industry reliability. Trust SIMA LABS to deliver the best in sun protection product testing.

Ensuring Clean Air, Protecting Health
In Vitro SPF Determination: SPF assesses how much UV radiation is needed to cause sunburn on protected skin compared to unprotected skin. Higher SPF values indicate stronger protection.
Broad Spectrum Analysis: In accordance with FDA guidelines, this test evaluates a product’s ability to protect against both UVA and UVB rays—two primary types of ultraviolet radiation.
Boots Star Rating: Widely recognized in the UK, this system measures UVA protection by evaluating UV transmittance through sunscreen films on PMMA plates. It calculates the ratio of UVA to UVB absorbance before and after UV exposure.
Critical Wavelength Measurement: Sunscreens achieving a critical wavelength of ≥370 nm are classified as broad spectrum, confirming protection across a wider UV range.
Water Resistance Testing: This test compares a sunscreen’s SPF before and after water immersion, following the International SPF Test Method, to ensure product effectiveness during water exposure.
At SIMA LABS, we uphold the highest standards of quality in all our testing services. Our SPF testing undergoes stringent quality control to ensure precision and reliability. We routinely calibrate our SPF transmittance analysers and adhere to strict protocols to maintain consistency in every test.
