The Ultimate Skin Ageing Duo

Infrared (IR) radiation (especially IR-A) penetrates deeper into the skin than UV or blue light, contributing to heat stress, oxidative damage and accelerated skin ageing.

Infrared radiation cannot be blocked by traditional sunscreen filters, physical or chemical. There are currently no approved cosmetic ingredients that reflect or absorb infrared light in the way sunscreen filters protect against UV. Skincare products support the skin’s resilience to infrared-induced stress through actives. Age Defence contains a powerful antioxidant complex including: tocopherol (vitamin E), carotenoids, polyphenols and DNA repair enzymes. These ingredients don’t block IR but help defend against oxidative stress, inflammation and mitochondrial damage that IR exposure can trigger.

We’ve chosen not to make the “infrared protection” claim because no skincare product can truly block infrared.

Blue light (HEVL, 400–500 nm) is part of the visible light spectrum and cannot be effectively blocked by transparent skincare formulations. Only products containing visible light–reflective ingredients, such as iron oxides, provide real HEVL protection. This means true blue light protection requires ingredients that physically reflect visible light.

Antioxidants can help mitigate the damage caused by blue light. Age Defence contains carotenoids, polyphenols and vitamin E to help mitigate oxidative stress caused by blue light and support the skin’s natural defence and repair mechanisms This means our formulation helps skin recover from blue light exposure, but it does not block blue light itself.

That’s why we’ve chosen not to make a “blue light protection” claim, even though we could have.

Absolutely! Night Repair Therapy and Age Defence are our hardworking duo that keeps your skin in a state of protection and repair day or night.

Yes, it sits beautifully under makeup offering all-day hydration. Can be worn alone or under makeup.

If you want to, you can use a separate antioxidant product before applying the day cream. However, it’s been designed to offer antioxidant protection as your one-step daytime cream.

When you apply sunscreen, many experience flocculation issues (probably without realising it). This means that, despite your best efforts, your application isn’t always even and can clump together. Using encapsulated technology means the sunscreen applies like a protective film over the skin, reducing any gaps and forming a better UVA and UVB protection layer.

The base ingredients, especially the repair enzymes have a distinctive smell. We added a very small amount of fragrance to boost the experience of using this daily.

Our day cream has been shown in independent clinical testing to be suitable for sensitive skin. Our encapsulated filter technology means the sunscreen filters themselves are not in contact with the skin making it suitable for those who are sometimes sensitised by sunscreen filters. 

The formulation is mildly fragranced so if you are concerned about any specific allergies or irritation we recommend trialing a small amount first.

As much as we’d love to say yes, unfortunately not all of it. DNA Repair Enzymes can’t erase all past DNA repair, but it can mitigate some DNA damage, helping to  correct UV-induced errors before they cause permanent cellular changes. In turn, this also helps reduce the risk of precancerous skin changes.

Age Defence is a day cream that contains broad spectrum sunscreen filters meaning you can wear it as a sunscreen. We just recommend applying a 2 finger length amount to ensure adequate protection and it’s important to reapply throughout the day.

Yes, that’s completely normal. Our Night Repair Therapy is made with potent natural ingredients, which can have subtle variations in scent from batch to batch. These variations occur because many of our ingredients are plant-based and harvested seasonally. Due to factors like climate, rainfall, and soil conditions, the harvest timing may vary slightly each year, affecting the aroma natural extracts. This is a normal part of working with high-quality botanical actives, it’s nature’s fingerprint.
