Z Clear Shikimic Hydroxy-Biome Facial Serum

30ml
$109.00

Clear skin. Intelligently delivered.

Z Clear Shikimic Hydroxy-Biome Facial Serum is a next-generation daily serum designed to target the five key features of acne-prone skin: excess oil, clogged pores, visible redness, breakouts and microbiome support.

Powered by the Hydroxy-Biome System, it combines Shikimic, Mandelic and Salicylic Acids to deliver triple-hydroxy acid exfoliation that helps decongest pores, refine texture and reduce excess oil. A dual prebiotic complex helps support a balanced skin microbiome while barrier-supporting actives maintain skin comfort throughout use.

With continued use, skin appears clearer, more balanced and visibly refined.

Apply 2-3 pumps to the face and neck in the morning and evening after cleansing. It is recommended to apply this serum once daily on alternative days, before gradually building tolerance to apply twice daily.

Hydroxy-Biome System

Shikimic Acid (AHA) – a gentle exfoliating acid that helps refine skin texture, smooth roughness and reduce the appearance of redness, making it well suited to blemish-prone skin requiring efficacy with tolerance.

Mandelic Acid (AHA) – a larger-molecule AHA that provides controlled, surface-level exfoliation to help improve uneven texture, support skin clarity and assist in reducing excess oil.

Salicylic Acid (BHA) – an oil-soluble exfoliant that penetrates into pores to clear excess sebum, impurities and dead skin cells, helping to reduce congestion and minimise the formation of breakouts.

Microbiome Support

Inulin + Alpha-Glucan Oligosaccharide – a dual prebiotic complex that helps nourish beneficial microorganisms, support a balanced skin microbiome and reinforce the skin barrier for healthier-looking and more resilient skin.

What You Need To Know

Z Clear Shikimic Hydroxy-Biome Facial Serum is ideal for oily, combination and breakout-prone skin, including adult acne. It's also suitable for anyone concerned with congestion, excess oil, enlarged pores or uneven skin texture.

Unlike traditional acne serums that focus on drying the skin, this serum takes a more balanced approach. Our Hydroxy-Biome System combines three complementary hydroxy acids with dual prebiotics to exfoliate and visibly clarify congestion while supporting the skin barrier and microbiome.

Shikimic Acid is a next-generation Hydroxy Acid that occurs naturally in Star Anise, an aromatic culinary spice. Its larger molecular structure allows for more gradual exfoliation, helping to smooth skin texture, refine pores and promote clearer-looking skin while maintaining skin comfort.

The Hydroxy-Biome System combines Shikimic Acid, Mandelic Acid and Salicylic Acid to deliver multi-level exfoliation. Dual prebiotics help support a balanced skin microbiome and healthy skin barrier, creating a more complete approach to clearer-looking skin.

"If you previously used Ultra Clear Treatment Lotion, think of Z Clear Shikimic Hydroxy-Biome Facial Serum as the next evolution in acne care.

While Ultra Clear Treatment Lotion focused primarily on breakouts, Z Clear Shikimic Hydroxy-Biome Facial Serum takes a more advanced, multi-layered approach. Our Hydroxy-Biome System combines Shikimic Acid, Mandelic Acid and Salicylic Acid to deliver multi-level exfoliation to help reduce breakouts, while dual prebiotics help support the skin microbiome and maintain the skin barrier.

The result is a more complete approach to clearer-looking skin that not only targets congestion and excess oil, but also helps support healthier-looking skin."

Yes. The serum is designed for daily use. Apply morning and evening after cleansing and before moisturiser. It is recommended to apply this serum once daily on alternative days, before gradually building tolerance to apply twice daily. We recommend wearing SPF during the day when using exfoliating acids.

Yes. This serum is dermatologically tested and suitable for sensitive skin. The formula has been developed to deliver effective exfoliation while supporting skin comfort. If you have sensitive skin or are new to exfoliating acids, introduce the serum gradually and increase usage as your skin adjusts.

As this serum already contains a blend of exfoliating acids, we recommend avoiding multiple exfoliating products in the same routine unless advised by your skincare professional.

Yes. It's also suitable for anyone concerned with congestion, enlarged pores, excess oil or uneven skin texture, even if they don't experience regular breakouts.
