L4B Porcelain Water Balm


or 4 installments from $9.75 by Afterpay More info

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.

At the end of the year we consult all of our L4B participants and consider adding a favorite L4B formulation to the permanent moss collection.

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.





This beautiful pressed serum is intended to be the most hydrating and protective balm you have ever experienced.

While balms typically include oils, waxes and butters, this “superbalm” includes all that and so much more.

Ceramides and phytosterols are added to help balance and repair the lipid matrix of the skin barrier.

Vitamin C, Bisabolol and Poria Cocos Extract enhance repair, soothe inflammation and thicken the skin barrier respectively.

A plant derived co-polymer works wonderfully to prevent trans-epidermal water loss and seal hydration into the skin.

Lastly, a hydric hydration complex infuses the skin with quenching ingredients such as hyaluronic acid, panthenol, anti-inflammatory oat proteins and more.

The oils, butters, waxes and other ingredients used in Porcelain are designed to be acne-safe.

16ml/8ml size
