Targeted Biome Bacteriolysis™: A New Antimicrobial Approach

Targeted Biome Bacteriolysis™ occurs when an endolysin peptidoglycan hydrolase effectively targets specific pathogenic bacteria while sparing unintended targets. This technology leverages the action of a bacteriophage to create an engineered endolysin.

  • Stage 1

    In nature, phage DNA enters bacterial cells at local activity of virion-associated cell wall hydrolases.

  • Stage 2

    Once inside the cell wall, new phages are released from the infected host cell, creating soluble lytic enzymes. These endolysins lyse the cell wall, targeting essential bacterial structure and ultimately resulting in bacterial death.

  • Stage 1

    Copying what our body does naturally, Micreobalance® is the first engineered endolysin peptidoglycan hydrolase that can effectively target specific bacteria of the microbiome while sparing unintended targets.

  • Stage 2

    Working from the outside in, topically applied endolysins lyse the bacterial cell wall. By targeting the bad and protecting the good, topically applied endolysins balance the skin microbiome.

Temporal Shifts in The Skin Microbiome Associated with
Disease Flares and Treatment In Children with Atopic Dermatitis

A Skin Microbiome Balancing Act

Healthy skin requires a healthy microbiome. But eczematous skin is often in dysbiosis: an estimated 80% of atopic dermatitis patients are overcolonized with S. aureus, a pathogenic bacteria that drives eczema flares. ², ³

Overcolonization is a moving target: it can occur on certain areas of the body but not others and recur over time. Addressing persistent microbiome dysbiosis is critical to restoring AD patients’ skin health.

Generational Skincare Inspired by Real People

AD patients’ skincare needs evolve as they progress through life. We are committed to creating products that improve people’s lives across generations.

Our Formulations

We partner with leading researchers and dermatologists to develop products optimized for patients living with atopic dermatitis. All of our ingredients are intentionally selected to promote skin health.

  • Micreobalance®

    Our proprietary endolysin that targets pathogenic bacteria, including antibiotic resistant strains.

  • Ethyl Macadamiate

    An essential fatty acid derived from macadamia nut oil that prevents moisture loss. Allergy-safe: no nut protein present.

  • Jojoba Esters

    A non-greasy emollient derived from jojoba that acts as an anti-inflammatory skin conditioner. Superior stability.

  • Glycerol

    A hydrating trihydroxy alcohol that supports skin elasticity and barrier repair.

About Us

Gladskin & GladskinMD are on a mission to improve quality of life for millions of people living with inflammatory skin conditions worldwide.

Our revolutionary non-prescription products for atopic dermatitis use patented endolysin science to balance the skin microbiome and restore skin health. GladskinMD is a subsidiary of the Dutch & Swiss biotechnology company Micreos Holdings, which is developing sustainable alternatives to antibiotics.
