[update] How ISO's Endorsement of Two Test Methods Will Enlighten Sunscreen Development

After 10 years, sunscreen developers are nearing the finish line for more ethical, cost efficient, reliable and faster testing thanks to ISO's endorsement of two standards. The final vote was in September 2024. Here, two experts explain what this means.

The authors believe that adding the properties of a wide range of commercial sunscreens to the system database will increase the rate of appropriate sunscreen usage by customers.

AmorePacific, Hanyang Univ. Dynamically Visualize UV Dose on SPF-protected Skin

Work by AmorePacific and Hanyang University, Seoul, published in Skin Research & Technology, reveals a dynamic approach to visualize UV dose based on MED, weather, outdoor activity, etc., on SPF-protected skin.

To prevent and repair UV-induced skin damage, a sustainable ingredient was developed from Sargassum vulgare, a brown seaweed that naturally evolved phlorotannins to defend against UV damage. The algae was fermented using a proprietary yeast to enrich this bioactive content; the resulting ingredient was tested as described here for skin benefits.

Brown Seaweed Ferment Propagates UV Damage Protection for Skin

To prevent and repair UV-induced skin damage, a sustainable ingredient was developed from Sargassum vulgare, a brown seaweed that naturally evolved phlorotannins to defend against UV damage.

TDF Blu Viole Sunscreen specifically protects the skin from not only sun damage but blue light as well, preventing hyperpigmentation, melasma and brown spots.

TDF Blu Voile Sunscreen Found to Protect Against Blue Light

The skin-protecting efficacy against the effects of blue light irradiation was analyzed, as well as the quantitative and qualitative evaluation of protein carbonylation in human skin explants.

The skin care industry has typically focused its testing on skin types 1 through 3, leaving 4% of tests with skin types 5 and 6.

Report: Superdrug Commits to Increase Sunscreen Testing on Darker Skin Tones

Impaired Barrier Affects Skin's Sensitivity to UV Radiation

Skin care products that improve skin conditions associated with UV sensitivity, and include sunscreen are important for protection against the hazards of UV radiation.

(Depiction only) The new method uses the spectroradiometric measurement of residual UV from a single pre-irradiation dose through a thin layer of sunscreen applied to a multi-layer substrate.

7 Years in the Making: CE Recommends In vitro SPF Double Plate Test Method

"... No in vitro method had [previously] advanced to the stage that CE could recommend it. So those who did not want to use an in vivo method could use any ... unvalidated method; this should no longer be the case."

Knowledge in sun protection has become more comprehensive, making sunscreen testing and development more challenging. This article explores what we know and what is needed in terms of sunscreen testing, regulation and consumer communication.
