The Science Behind Phage-Based Acne Care

What Are Bacteriophages?

Phyla uses 'phages'—naturally occurring microorganisms that selectively target C. acnes, the bacteria associated with acne. By focusing only on acne-causing bacteria, phages support a balanced skin microbiome.

Acne and the Skin Microbiome

Acne and the Skin Microbiome

Healthy skin depends on a balanced microbiome—a community of beneficial bacteria that protects the skin barrier. When C. acnes bacteria become dominant, inflammation and breakouts can occur.

Unlike traditional treatments that disrupt bacteria broadly, bacteriophages selectively target C. acnes while leaving beneficial bacteria intact.

Phyla vs. Traditional Treatments

Traditional Treatments

Many acne treatments eliminate bacteria broadly, which can disrupt the skin barrier and microbiome.

Phage Technology

Bacteriophages are naturally occurring microorganisms that selectively target C. acnes, leaving beneficial bacteria intact.

Phyla’s serum contains billions of bacteriophages that activate on contact with the skin. These phages selectively infect C. acnes, helping reduce acne while preserving beneficial microbes.

Hormonal Acne

Linked to fluctuations in hormones particularly during puberty, menstruation, pregnancy, or menopause.

Phyla’s Approach: Helps regulate the inflammatory response triggered by hormonal changes.

Cystic Acne

A more severe form of acne caused characterized by large, painful, pus-filled, bumps deep beneath the skin.

Phyla’s Approach: Targets the bacteria associated with deep, inflamed breakouts to help calm skin.

Teen Acne

Very common during puberty and is driven by hormonal changes that increase sebum production.

Phyla’s Approach: A gentle, microbiome-friendly approach that avoids irritating treatments that are harsh on young skin.

Nodular Acne

Consists of hard, painful bumps beneath the skins surface. Often inflamed and can persist for weeks or months.

Phyla’s Approach: Targets the bacteria associated with deep, inflamed breakouts to help calm skin.

Blackheads

Open comedones appearing as small, dark spots on the skin’s surface. The color is from oxidized sebum, not dirt.

Phyla’s Approach: A balanced microbiome supports healthier pores and helps reduce clogging.

Whiteheads

Closed comedones that occur when pores are clogged with sebum or dead skin cells.

Phyla’s Approach: A balanced microbiome supports healthier pores and helps reduce clogging.

Hormonal Acne

Linked to fluctuations in hormones particularly during puberty, menstruation, pregnancy, or menopause.

Phyla’s Approach: Helps regulate the inflammatory response triggered by hormonal changes.

Cystic Acne

A more severe form of acne caused characterized by large, painful, pus-filled, bumps deep beneath the skin.

Phyla’s Approach: Targets the bacteria associated with deep, inflamed breakouts to help calm skin.
