L4B Quantum Glow Liquid Radiance Droplets


or 4 installments from $26.25 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.




The concept:

A true quantum radiance blast. Out of this world concentrations of proven all-star ingredients. Equally beneficial and powerful for both acne and aging concerns.

Try bakuchiol – the plant-based retinol dupe that creates the exact same skin renewal that makes retinol the ingredient millions reach for when addressing acne or fine lines but without the irritation or safety concerns of retinol. Most, if not all skincare, includes bakuchiol at 1% – we have boosted it to 5% in this ultra concentrated formula for next-day results.

Tetrahecyldecyl Ascorbate is a stable, very powerful form of Vitamin C. Here are some statistics illustrating how multi-correctional and beneficial it can be:

  • At 0.1% reduces melanin synthesis by 80%
  • At 10% eliminated age spots in 16 weeks
  • At 0.1% increases collagen by 50%
  • Acne clearing at 10% with 80% patient satisfaction
  • Increases collagen synthesis 2-3x better than ascorbic acid
  • Inhibits inflammatory proteins MMP-2 and MMP-9 better than ascorbic acid

We’ve included this uber-ingredient at a whopping 15%.

Lastly, bisabolol is included at 0.5% for it’s anti-inflammatory and anti-bacterial properties.

What makes this so exquisite however, is the gorgeous base of oils these star ingredients are coddled in.

Rare unrefined honeydew melon oil (similar to cucumber, watermelon and Kalahari melon oils) and unrefined blackberry oils (similar to raspberry oil).

Has a very faint beautiful natural scent that is completely essential oil free and is simply due to the fact that these oils are ultra pure and unrefined. 

Last but not least, we include an absorption enhancer to ensure these powerful ingredients are getting delivered to the skin to work their magic.
