What is the L4B?

moss founder Celestyna created the L4B as a place to fulfill her curiosity and creativity. New ingredients, formulations, and techniques are tested, including ultra powerful and specific products Celestyna creates for her seasonal needs. Some of these exceptional creations we make available for you as couture experimental skincare – extremely limited quantity and always expertly hand-crafted by the proprietress herself.

Please note, due to the foundational concept of the lab, each batch will vary slightly – it may have slightly different ingredients and different percentages of ingredients. The L4B is NOT a conventional, static skincare line – it is a formulator’s playground.
