Fermentation is a natural biological process where microorganisms like bacteria and yeast break down organic materials—such as plants and fruits—into smaller, more active compounds. Think of it as nature’s way of “pre-digesting” ingredients, making them easier for your skin to absorb and benefit from.  For centuries, humans have used fermentation to preserve and enhance foods like yogurt, kimchi, and sourdough bread. Today, we’re tapping into this age-old method to revolutionize skincare by unlocking powerful bioactive ingredients that help maintain healthy, balanced skin. 

At Alkylo, we don’t just add fermented ingredients—we cultivate live biotransformation right in our formulations.
Here’s why that matters: 

• Enhanced Potency: Fermentation can increase antioxidant activity by up to 50-70% and vitamin content by 20-40%, making nutrients like vitamins C, B, and amino acids more concentrated and effective (Kim et al., 2019; Park et al., 2020). 
• Improved Absorption: Fermentation breaks down large molecules into smaller peptides and organic acids, improving skin absorption by as much as 30% compared to non-fermented ingredients (Lee et al., 2018). 
• Gentle on Sensitive Skin: Fermentation reduces irritation potential by neutralizing harsh compounds, leading to a 25% reduction in skin redness and inflammation in sensitive skin trials (Cho et al., 2021). 
• Supports Your Skin Microbiome: Fermented ingredients encourage a balanced skin microbiome by producing postbiotic compounds that nourish beneficial bacteria and inhibit pathogens (Gomes et al., 2019). 

We use carefully selected strains of beneficial microbes, including Lactobacillus and Bifidobacterium, to ferment botanical extracts. This process creates a rich blend of bioactive compounds, including: 

• Postbiotics: Non-living, skin-loving compounds like peptides and organic acids that soothe and strengthen the skin barrier. 
• Enzymes: Molecules that support gentle exfoliation and skin renewal. 
• Antioxidants: Powerful agents that protect against environmental damage and premature aging. 

Our fermentation happens under controlled, sustainable conditions to preserve the potency and purity of these actives, making our skincare uniquely effective and microbiome-friendly. 

Unlike products that simply contain fermented ingredients, Alkylo’s formulations incorporate freshly fermented blends developed through our proprietary processes. This means you get the freshest, most bioavailable actives possible—delivering real results without compromising skin health.  Plus, because fermentation produces postbiotics rather than relying solely on live bacteria, our products are stable, safe, and suitable for all skin types, including sensitive and reactive skin. 

Studies show that fermented skincare ingredients can: 

• Increase skin hydration by boosting hyaluronic acid levels by up to 40% (Pérez et al., 2020). 
• Improve skin texture and firmness in as little as 4 weeks (Kim et al., 2021). 
• Calm inflammation and redness by modulating immune response (Cho et al., 2021). 
• Promote a balanced, thriving skin microbiome (Gomes et al., 2019). 

At Alkylo, we’re proud to blend tradition with science to deliver these benefits in every bottle. 

Fermentation isn’t just a buzzword — it’s the cornerstone of Alkylo’s microbiome-friendly skincare philosophy. By embracing this natural process, we unlock skincare that’s more effective, gentler, and in tune with your skin’s unique ecosystem.
