L4B Jade Tea Water Balm


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 includes an amazing array of butters:

Cupuacu (an intensely moisturizing, lanolin-like (vegan/plant-based) substance)

Kokum (dry and waxy feeling, kokum has incredible antioxidant and anti-inflammatory properties)

Bacuri (a butter so dark brown it’s almost black, bacuri contains unique antioxidants and nutrients)

Ucuuba (very unique and acidic, useful for resolving skin barrier issues and powerfully mitigating for acne)

Murumuru (has been called vegetable silicon, unique silky skin feel and blurring capabilities)

We use all acne safe oils:

Pracaxi – amazing for cell regeneration and scarring resolution

Sapote – both intensely nourishing and also active against acne

Milk Thistle – detoxifying, anti-inflammatory and healing, high in phytonutrients

White Mustard – another oil that is not only acne-safe but also actively preventative, naturally high in sulphur compounds.

Bayberry and green tea esters create a breathable layer of protection.


Blue tansy and oat help soothe inflammation.

A very high percentage of ceramides and sterols is added for helping to balance and thicken the lipid matrix in the skin barrier.

Other skin loving ingredients include stable Vitamin C, bisabolol (which helps with acne inflammation specifically) and a hydration complex based on fermented sugars that has been shown to help skin hold greater hydration levels for 72 hours from application.

(Please note, this formula is an evolution of Porcelain Water Balm and the label will still say “Porcelain Water Balm” when you receive the product.)

16ml/8ml size
