RoseKin Cosmetics

Jessica Gross noticed a pattern many know: sunscreen was in the bathroom – but it wasn’t used daily. The texture was too heavy, the step too much, the feeling on the skin not satisfying enough.

At the same time, dermatological studies clearly showed that UVA radiation is one of the main factors of premature skin aging – and that this protection is relevant not only on vacation but daily and all year round.

Her answer was not a campaign for more awareness. It was products that structurally solve the problem: integrating sunscreen where it is already applied. Foundation. Powder. Day cream.

For the formulations, Jessica Gross turned to Korean expertise – an industry that has treated daily sunscreen for decades not as an extra step but as the foundation of skincare. Combined with Swiss design standards, this resulted in RoseKin: a brand that rethinks sunscreen – not as an obligation, but as a natural part of the daily routine.

Most people think of sun protection as something for the beach and summer. The reality is different: UVA rays are active year-round, penetrate clouds and window glass, and reach the deeper layers of the skin – regardless of whether you are outside or not.

While UVB rays are mainly responsible for sunburn, UVA rays are the main factor in light-induced skin aging: fine lines, pigmentation changes, loss of skin elasticity. These damages do not result from a day at the beach but from years of everyday exposure – in the car, at the office window, during a walk.

Korea integrated this insight into its cosmetic culture earlier than most other countries. The local sun protection industry has developed textures over decades that don’t feel like sun protection – light, non-greasy, invisible on the skin. This enables actual daily use, not just theoretical.

RoseKin uses this formulation expertise and focuses it on a clear goal: UVA protection in everyday life, integrated into products that people really use daily. Because the most effective sun protection is the one that actually ends up on the skin.
