why we use chlorella vulgaris (microalgae) extract

Microalgae: A Versatile Skincare Powerhouse

Microalgae offer a wide range of benefits in skincare, depending on how they're sourced and processed. These single-celled organisms produce powerful bioactives—including antioxidants, peptides, and hydrating polysaccharides. As a result, they help protect against oxidative stress, improve hydration, boost cell renewal, and support microbiome balance.

Importantly, microalgae are also highly sustainable. They grow quickly, capture carbon efficiently, and require minimal land or resources. Thanks to this versatility and eco-profile, they’re becoming a staple in advanced skincare formulations.

Advanced Skin Renewal via Cellular Signalling

In Cipher formulas, we use a specialised extract from Chlorella vulgaris cell walls. We chose it for its ability to drive skin renewal and support the microbiome.

This prebiotic active promotes tissue repair and helps reinforce the skin barrier. It visibly improves clarity and resilience by activating key signalling molecules. In fact, studies show it outperforms epidermal growth factor (EGF) in supporting keratinocyte growth and movement.

Specifically, it stimulates transforming growth factor alpha (TGF-α) and Dikkopf-1 (DKK-1)—signals linked to epidermal thickening and repair.

Microbiome Modulation and Prebiotic Defence

This extract also actively supports a balanced microbiome. It encourages the growth of S. epidermidis (a beneficial skin species) while suppressing problematic microbes like P. acnes (acne), M. furfur (dandruff), and S. aureus (linked to atopic dermatitis).

At the same time, it strengthens the skin’s immune defences. It boosts production of antimicrobial peptides such as CXCL10, which helps calm inflammation and reinforce resilience.

Together, these effects create a comprehensive prebiotic effect. Clinical studies show it helps clear skin and reduce the visible impact of inflammatory reactions.
