Daily SPF is something I take very seriously. It is the cornerstone of my skincare routine, and I never miss it. For that reason, I am always interested in formulas that not only protect but also make it easy to use. Like most people, I find reapplication a challenge and so when I was introduced to Klira The Dayscript which promises 8 hours of sun protection in one application at an event earlier this summer, I was eager to try it. Here’s what you need to know.
What is Klira The Dayscript?
This is Klira’s latest innovation: a 7-in-1 targeted daily skincare treatment with SPF50 PA++++. It is described as an all-in-one daytime skincare solution. Rather than layering multiple products, it has been formulated to meet the skin’s daytime biological needs in a single application.
It combines:
- High-level UV protection with SPF50 PA++++ and encapsulated sunscreen technology for up to 8 hours of protection.
- Antioxidants including resveratrol bioferment, ubiquinone, Phytexcell Liquorice, and Vitamin E, which defend against oxidative stress, pollution, and visible light damage.
- Peptides to support collagen and maintain firmness.
- Hydrating ingredients for comfort throughout the day.
- Soothing actives to calm and strengthen the skin barrier.
Crucially, this is not a generic formula. It is tailored to your SkinSize profile, identified via an online consultation, ensuring you receive the precise formulation that aligns with your skin’s needs.
The Science Behind It
Daytime is when the skin is most exposed to stressors such as UV rays, pollution, and oxidative damage. It is also when DNA repair enzymes are at their most active, and antioxidant defences are in demand.
The Dayscript is designed to map directly onto this daytime molecular profile, supporting:
- DNA repair when it is most needed
- Advanced mitochondrial defence (key to cellular health and longevity)
- Collagen synthesis and structural support
- Antioxidant protection exactly when the skin requires it
This intelligent design places it in a category beyond a conventional daily SPF.
Review of Klira The Dayscript
I have been testing it over the past few months, and here are my considered thoughts.
My Experience
I trialled The Dayscript from a plain sample tube, which made the experience feel almost like testing a secret prototype.
The texture is lightweight and smooth, blending easily without leaving residue, pilling, or a white cast. It feels hydrating, yet weightless, and crucially, it sits beautifully beneath makeup. In fact, it functions very effectively as a primer, helping foundation to apply evenly and last longer.
I generally apply two layers, three pumps each, which provides ample coverage. Knowing that the encapsulated sunscreen technology is delivering up to 8 hours of protection gives me enormous peace of mind, especially on days when reapplication isn’t practical. Game changer!!
How It Compares to Klira’s Night Product
Klira’s original launch was a one-step night treatment. While I admire the innovation, I must admit I found it difficult to embrace. I enjoy the ritual of layering different treatments at night, and the Klira night formula did not feel sufficient for my skin’s hydration needs.
The Dayscript, however, is entirely different. It is practical, protective, and perfectly suited to mornings, particularly when time is short. This is the product from Klira that I can genuinely integrate into my lifestyle.
Subscription and Personalisation
The Dayscript can be purchased individually, but Klira recommends the auto-replenish subscription. This ensures you receive a fresh formulation each month (potency is prioritised) and gives you access to Klira’s Dermatology Team for ongoing support. Subscriptions also provide a cost saving, which makes sense for a product designed for daily use.
Results
I have really enjoyed using this over the summer and here are my summarised thoughts on it:
- Confidence in sun protection – I felt assured wearing this all day without topping up
- Hydration and comfort – my skin remained balanced and comfortable throughout wear
- Enhanced makeup performance – I think using less product genuinely improved makeup longevity
- Simplicity – one step in the morning, no risk of ingredient incompatibility.
Although I still enjoy experimenting with other product combinations, on long days out, particularly in the sun, this is the formula I prioritise.
Klira The Dayscript – FAQs
What is Klira The Dayscript?
A 7-in-1 daily skincare product combining SPF50, antioxidants, peptides, hydration, and primer-like benefits in one step.
How long does it last?
Klira The Dayscript offer up to 8 hours of UVA/UVB protection, thanks to encapsulated sunscreen technology. Reapplication is only required after swimming or heavy perspiration.
Is it suitable as my only morning product?
Yes. It is designed to replace serum, moisturiser, primer, and SPF in a single application.
How is it personalised?
You complete an online consultation that determines your SkinSize. Klira then prescribes the formulation that best meets your profile.
What differentiates it from a standard SPF?
First of all it provides all day UV protection, but beyond that, it actively supports the skin’s daytime biology, delivering antioxidant defence, mitochondrial support, and collagen maintenance.
Final Thoughts
For me, Klira The Dayscript represents a genuine step forward in intelligent, dermatologist-designed skincare. It streamlines the morning routine without compromise, provides reliable long-lasting protection, and enhances the performance of makeup.
It is rare to find a product that feels both practical and sophisticated. The Dayscript achieves this balance, and I can see it becoming indispensable for those who value efficiency, efficacy, and for anyone that wants to reapply sunscreen but find it really hard to do that!
