Probiotic Strain: Lactobacillus Ferment
This protective ingredient fortifies your skin barrier against external stressors while soothing and hydrating. It's known to help repair damaged skin, rebalance skin flora, and reduce harmful bacteria growth.

Orobanche Rapum Extract 
Grown in southern France, and well known for its antioxidant activities and biological properties, this effective extract actively protects skin stem cells and balances the microbiome.

Meadowfoam Oil
With a similar texture to sebum, and rich in vitamin E, this efficacious and lightweight oil locks in moisture, balances the skin and enhances other skincare ingredients for softer, plumper skin.

Lactic Acid
As the gentlest of the Alpha Hydroxy Acids (AHAs), lactic acid helps improve skin’s natural moisture. And with continued use it helps firm skin, fade spots, and smooth fine lines and wrinkles.

Cell turnover is the continuous process of shedding old skin cells and bringing new ones to the surface; a process that slows as we age. We developed Layers Probiotic Serum to speed your skin’s replenishing cycle for continually vibrant, glowing skin.

Our highly concentrated, ultra-absorbing serum delivers probiotics, Orobanche rapum plant extract and meadowfoam oil deep within your skin's active layer. This potent blend accelerates skin cell turnover while protecting your microbiome for dramatic results without irritation. 

Our gentle but incredible serum protects healthy skin cells and increases their ability to replicate and rise to the surface to reveal visibly plumped, hydrated and luscious-feeling skin.

Layers Probiotic Serum is for all skin types. Whether you have dry skin, oily skin, or combination skin, Layers products bring balance to your microbiome.


After cleansing with Layers Balancing Milky Cleanser, apply one pump of serum to palms. Rub hands together to warm the product. Gently but firmly press palms over the entirety of the face, neck and chest in a stamping motion to layer an even veil of product to the skin. Follow with Layers Immunity Moisturizer.
