Science and research

Every ingredient has a reason.

Each LARSA product is built on ingredients that research has studied, and we share that research openly.

Our approach

Our approach to ingredients.

For each product we gather what peer-reviewed research says about its key ingredients, and show it here with links to the studies.

Hydration, balance, gentle exfoliation or sweetness without sugar: each key ingredient is there for a clear purpose.

Dentists and specialists explain our products in videos on our Instagram.

Research by product

These studies are about the ingredients in general, not about LARSA products specifically. This page is for information and is not medical advice.
