About Varentis

A Swiss consultancy for ESG documentation.

Varentis exists so that cosmetics brands say only what they can prove.

01. The Company

Varentis reviews cosmetic and personal-care claims against their evidence and builds the documentation behind them. We are a new, founder-led practice based in Ticino, working with brands, contract manufacturers and agencies.

02. The Gap We Solve

Claims on packs, product pages and adverts must be true and provable. New rules on environmental claims have applied in the EU since 27 September 2026, and Switzerland has required proof for climate claims since 1 January 2025. Often the claims are there, but the evidence file behind them is not. We build it.

03. The Founder

An MBA in Sustainability Management

Varentis is run by Mirriam Costa, based in Ticino. She holds an MBA in Sustainability Management and has published fourteen articles on EU and Swiss cosmetics regulation.

Mirriam also founded STEMOVA, a Swiss skincare brand. Varentis keeps client information entirely separate from STEMOVA: separate systems, separate storage, and a written conflict check before every engagement. If you consider STEMOVA a competitor, tell us before sharing anything and we will discuss whether we are the right provider.
