How to use

Apply generously to the face every morning as the final step of your skincare routine. Overexposure to the sun is dangerous: do not stay too long in the sun, even when using a sunscreen product. Applying an insufficient amount significantly decreases the level of protection.

The dermatologist advice

"The most powerful anti-ageing step for skin longevity is daily photoprotection.
Light exposure occurs every day, and cumulative damage accelerates collagen breakdown and cellular fatigue.
Applying sunscreen daily helps preserve skin structural integrity, protect mitochondrial function, and maintain long-term skin resilience."

Clinically proven results

Proven 8H protection and reinforced skin

While conventional sunscreens can degrade or wear off throughout the day, SUNLUTION Lumi-Shield Daily Fluid is visually proven to maintain a uniform protective film for up to 8 hours. Even after a full day of wear, the shield remains intact, ensuring continuous protection.

Beyond long-lasting surface defence, our PhotoAdaptive Technology™ reinforces UVA protection in real time as light intensity increases.

After 28 days of use, skin is not only protected, but visibly strengthened:

  • Stronger integrity: the skin barrier is significantly reinforced against daily environmental stress.
  • Refined skin texture: clinically proven to smooth the skin and reduce the appearance of crow’s feet.

Clinical & technology results

Enhanced UVA defence and cellular protection

PhotoAdaptive Technology™ helps reinforce UVA protection in response to light exposure while supporting more stable, long-lasting photoprotection. It also contributes to reducing UV-induced oxidative stress and mitochondrial damage, helping preserve skin integrity and long-term resilience.

Additionally, Triactionβ Film Technology™ forms a lightweight, even film that optimises coverage while helping soothe light-induced stress and reinforce the skin barrier.

Methods

1) Sustain UVA protection for up to 8 hours: Based on instrumental testing under continuous UV exposure conditions. Results may vary depending on usage conditions.

2) Enhanced UVA protection under UV exposure: Based on internal in vitro testing using PMMA plates under high-intensity UV irradiation. Under accelerated conditions,
60 minutes of exposure simulates approximately 8 hours of natural sunlight.

Expert Answers from Dermatologist

Thierry Passeron,
MD, PHD
Sunlution’s founder

Why should I use Lumi-Shield Daily Fluid everyday, even when the sun is not out?

Skin is exposed to light everyday, not just when the sun is visible. UVA rays, which contribute to photoageing, are present year-round and can penetrate through clouds and windows. In addition to UV, modern skin is also exposed to visible light and urban environmental stressors, such as pollution, that can contribute to oxidative stress. Using Lumi-Shield Daily Fluid as part of your daily routine helps protect skin from these invisible aggressors while supporting long-term skin resilience and helping to prevent signs of light-induced ageing.

It's advanced Tri-Action Film Technology™ forms a flexible protective layer on the skin that helps the formula remain stable during normal daily activities.

We recommend reapplying after swimming, sweating or towel drying to maintain optimal protection throughout the day.

Lumi-Shield Daily Fluid has been formulated with lightweight, breathable ingredients designed to sit comfortably on the skin without clogging pores. The fast-absorbing fluid texture allows the formula to create an even protective layer while remaining suitable for daily use on most skin types, including combination and oily skin.
