How does The Day Script work?

The Day Script optimises 7 functions of the skin in one daily application: Advanced UV Protection via 8-hour time-release encapsulated sunscreen; Inflammation Prevention with Red Algae Water; Synergistic Anti-Oxidants combining Phytexcell Liquorice, Resveratrol Bioferment and Vitamin E; Collagen Support with Polypeptide 121; Cellular Health with Matrixyl Morphomics; Deep Moisturisation with Polyglutamic Acid; and Skin Barrier Enhancement with Rosehip Seed or Jojoba Oil depending on your SkinSize™.

How do I use The Day Script?

The Day Script is your morning essential, replacing all morning serums and creams. Apply after cleansing and allow it to fully absorb before applying makeup. It is the optimum morning pairing to The Klira Special for 24-hour skin health.

What is the Klira routine?

The Dayscript and The Klira Special are bespoke, one-step formulas tailored to your skin's unique needs — morning and evening — for complete 24-hour skin support. Powered by your SkinSize™, they form your bespoke Klira routine, designed by dermatologists to make optimising skin health effortless.

What if my SkinSize™ answer is wrong?

The test is grounded in global dermatological research and designed to accommodate some variation in responses while still delivering an accurate result — answer the questions honestly and there's no way to get it wrong. Your answers, along with your photographs and any relevant medical information, will be carefully reviewed by our Dermatology Team as part of a full consultation.

What ingredients will I get?

We only work with the most well-evidenced molecules available. Core ingredients across all SkinSize™ variants include Advanced UV Radiation Screen, Red Algae Water, Phytexcell Liquorice, Resveratrol Bioferment, Vitamin E, Polypeptide 121, Matrixyl Morphomics, Polyglutamic Acid, and Rosehip Seed or Jojoba Oil. Additional ingredients are tailored to your SkinSize™ — for example, Nano-Lipobelle H-EQ10 for hyperpigmented skin types, and Fermented Oat Extract and Lipid Concentrate for dry skin types.
