SGS Introduces Hybrid Diffuse Reflectance Spectroscopy Testing for Sunscreens

SGS, a leader in testing, inspection, and certification, has made a significant stride in the field of cosmetic safety by launching Hybrid Diffuse Reflectance Spectroscopy (HDRS) testing for sunscreens. This revolutionary testing method evaluates sun protection factor (SPF), UVA protection factor (UVA-PF), and critical wavelength, thereby aiming to enhance consumer safety and product efficacy.

The HDRS method was developed over five years and was officially adopted as an international standard in December 2024. Amol Dev, Head of Cosmetics and Personal Care at SGS in North America, noted that this development underscores their commitment to safety, innovation, and sustainability in consumer product testing. With consumers and brands increasingly seeking assurance regarding the effectiveness of SPF products, SGS is stepping up to fill that gap. The rise in testing requests for sunscreen and skincare products reflects the industry’s growing awareness of the need for reliable testing methods amidst recent concerns regarding product safety.

Sunscreen products are classified by regulatory bodies, such as the U.S. FDA, as over-the-counter drugs, necessitating rigorous testing to substantiate safety and effectiveness claims. To meet regulatory compliance, it is paramount that laboratories validate SPF ratings, ensure broad-spectrum protection against harmful UVA/UVB rays, and confirm water resistance capabilities. The increasing demand for ethically produced and effective personal care products further drives the need for credible testing methods like HDRS.

The HDRS technique is notable for its non-invasive approach, connecting both in-vivo and in-vitro testing processes to yield a thorough understanding of efficacy. Unlike traditional in-vivo testing that exposes skin to UV radiation to induce redness or pigmentation, HDRS employs an optical assessment that avoids inducing erythema, providing a safer alternative without compromising accuracy. The integration of both testing methods enhances the reliability of results, offering quick and cost-effective turnaround times.

Traditional methods have faced ethical scrutiny because they involve intentionally causing skin redness to measure SPF effectiveness. In contrast, while validated in-vitro alternatives exist, they often overlook the critical aspect of human skin exposure. The HDRS method offers a compromise, capturing essential data without ethical dilemmas and has been endorsed by the international ALT-SPF Consortium initiated by ISO/TC 217.

SGS's proactive strategy aligns with significant megatrends in the TIC industry, particularly the increasing demand for high-quality assurance in personal care products. With over 40 years of demonstrated experience in servicing cosmetics, hygiene, and personal care sectors, SGS continues to pave the way for innovation in product testing.

As consumers become more informed and seek products that not only perform well but are ethically tested, the introduction of HDRS testing represents a likely turning point in sunscreen efficacy assessments. With its commitment to high standards, SGS also aims to help brands navigate the regulatory landscape, ensuring compliance while fostering innovation.

Moreover, SGS extends an invitation to industry experts and interested parties to discuss HDRS testing further at the upcoming FLSCC 2025 Sunscreen Symposium, highlighting their dedication to collaborating with the industry in pursuit of higher safety standards.

SGS operates over 2,500 facilities across 115 countries, employing 99,500 professionals dedicated to helping organizations meet quality, compliance, and sustainability benchmarks. The firm has a legacy of over 145 years and prides itself on delivering precision and reliability in testing services, enhancing consumer trust in product safety.

As SGS positions itself as a trusted partner in the personal care industry, the launch of HDRS testing not only reinforces its role in verifying product claims but also exemplifies its overarching mission: ‘When you need to be sure.’ This commitment to excellence ensures that brands can navigate the complexities of regulatory requirements while maintaining the highest standards of quality and consumer safety.
