The Science Behind Our Most Powerful Acne Serum

Acne is rarely just about oil. 

It’s shaped by hormones, inflammation, bacteria, stress and increasingly, the health of the skin’s microbiome. Which is why targeting it effectively requires more than a single active. 

It calls for a more complete, considered approach. 

For years, acne products have taken a singular path: reducing excess oil or clearing pores, often aggressively. While this can deliver short-term results, it can also disrupt the skin’s natural balance, leading to sensitivity, dehydration and recurring breakouts. 

Today, acne care is evolving. 

According to our Head of Research & Development, Dr Sally Noushini, effective acne care is no longer just about treating visible breakouts. "We're seeing a shift away from aggressive treatment alone and towards formulations that support overall skin health," she tells us. 

At the centre of this shift is Z Clear Shikimic Hydroxy-Biome Facial Serum, our latest innovation for blemish-prone skin. Powered by our advanced Hydroxy-Biome System, it combines targeted exfoliation with microbiome support to help reduce breakouts while maintaining skin balance. 

Rather than relying on a single acid, the Hydroxy-Biome System works across multiple levels of the skin. 

Salicylic Acid penetrates within the pores to help clear congestion at its source, while Mandelic Acid offers controlled, surface-level exfoliation to refine texture. Shikimic Acid, with its slower, gentler action, works at the surface to smooth and support clarity. 

Together, they create a layered, more intelligent approach, addressing breakouts from the surface through to the pore. Because acne is rarely driven by a single factor. 

But effective acne care goes beyond exfoliation. 

Healthy skin depends on a balanced microbiome: a delicate ecosystem that helps support the skin's natural defences and maintain overall skin function. When this balance is disrupted, skin can become more reactive, more congested and more prone to recurring breakouts. 

That’s why the Hydroxy-Biome System goes further. 

By incorporating dual prebiotics, Inulin and Alpha-Glucan Oligosaccharide, the formula helps support the skin's natural microbiome while maintaining hydration and comfort. 

"The future of acne care lies in balancing efficacy with skin health," says Dr Sally. 

The result is skin that feels calmer, more stable and better equipped to maintain clarity - exactly as skin should.
