The Founder

Silhouette by S is a French brand founded by Sarah Boudenne.
Sarah Boudenne started taking a passionate interest in beauty from an early age, especially the benefits of snail mucin, a natural, environment-friendly ingredient. In 2017, she decided to create her own brand to highlight her ground-breaking products made with snail mucin. She started out manufacturing and marketing just two products, her gentle soap and face repair gel, which both met with instant success. Sarah Boudenne soon expanded her Silhouette by S product range by developing a host of other cosmetics with her laboratory. She then created beauty routines for daily use catering to all skin types.


The products are formulated and manufactured in laboratories in France and Europe. All products are fully compliant with all current regulations, which set the highest standard in terms of safety and efficacy. Silhouette by S cosmetics contain 99% natural ingredients and are tested dermatologically.

Sarah Boudenne has designed several cosmetics ranges featuring snail mucin as their primary ingredient. Snail mucin has been used since ancient times and has long been studied in medicine. Its properties are well known in Japan. Snail mucin is brimming with active ingredients such as collagen, elastin, protein and glycolic acid. It will be your best ally in your daily beauty routine.

The benefits of snail mucin:

- Contains allantoin, which boasts healing and regenerative properties.
- Treats blemishes such as those caused by acne.
- Contains glycolic acid which boasts exfoliating, softening and lightening properties.
- Contains collagen to preserve skin structure.
- Contains elastin to maintain elasticity and a supple skin.
- Contains antioxidant vitamins A, C and E.
- Boasts natural antibacterial properties to fight infection.
- Attenuates scars, stretch marks and burns.

The mucus is harvested in a spirit of respect for the animal’s natural cycle, using a natural, animal-friendly process.
