Immediate intensive hydration
Developed through extensive in-house research, the Louis Widmer Biostimulators Complex is a proprietary blend of nine precisely selected amino acids and forms the core of most Louis Widmer skincare formulas. As the brand’s signature ingredient, it supports resilient, revitalised skin and delivers its benefits deep within the skin layers.
The biostimulants provide noticeable hydration within just 30 minutes, help reinforce and restore the skin barrier, and enhance cell vitality by stimulating renewal processes and collagen production.
When paired with carefully chosen complementary key ingredients, each formula unfolds its targeted effectiveness while remaining exceptionally well tolerated.
