The Dermatest tolerance test

Dermatest GmbH tested all four products in January 2026 with a patch test on 30 people per product. Each was rated "Excellent". A tolerance test checks how well skin tolerates a product. It does not measure results.

Certified vegan

All four products are certified vegan by the Korea Agency of Vegan Certification and Services. The certificates are valid until March 2028.

Sun protection, measured on people

The Soothing Veil Mineral Sunscreen was tested in three ways by a dermatology research institute in Korea in January and February 2026:

• SPF, measured on people according to ISO 24444. It is labelled SPF 50+.
• UVA protection, measured on people according to ISO 24442.
• UVA protection in the laboratory, measured according to ISO 24443.

Together the results meet the EU recommendation for UVA protection: at least one third of the SPF, with a critical wavelength of at least 370 nm. That is what the UVA seal on the pack stands for. Zinc oxide is the sunscreen's only UV filter.

The consumer study

In 2026 each of our four products was tested on its own in a consumer study run by an external test lab. For every product, 30 women in Europe aged 26 to 60 (28 to 60 for the essence and the cream) used it for 28 days.

At the end they said how far they agreed with statements about how the product felt and how their skin felt. It is a self-assessment: it shows how the products felt to the women who used them, not a measurement of skin.

We publish a statement only when at least 24 of 30 women agreed with it, and a result belongs only to the product that was tested. The results for each product are on its product page.

Fragrance-free, and EU safety rules

None of our four products contains added fragrance.

Like every cosmetic product sold in the EU and the UK, each of ours has a safety assessment and is notified in the EU portal for cosmetic products (CPNP) and the UK's Submit Cosmetic Product Notifications (SCPN).
