Sun exposure is the primary external driver of skin ageing, collagen degradation, pigmentation and barrier disruption. Much of this damage occurs through daily, cumulative UV exposure, not just intense or prolonged sun exposure.

While SPF is essential, protection alone does not address the secondary biological effects of UV exposure, including oxidative stress, inflammation and increased transepidermal water loss (TEWL). These processes continue even after sun exposure has ended, contributing to long-term skin damage.

The UR Sun Defence System is a laboratory-developed, clinically intelligent solution designed to address the complete lifecycle of sun exposure – from protection through to recovery and visual enhancement.

By combining SPF50+ mineral UV defence, SPF6 radiance layering, optical glow enhancement, and barrier-supportive hydration, this system delivers a comprehensive approach to skin defence and appearance.

DEFEND – SPF50+ Mineral UV Protection

UR Sun Cream SPF50+

Formulated with zinc oxide, a physical UV filter that reflects UVA and UVB radiation before it penetrates the skin.

Supporting emollients such as Coco-Caprylate/Caprate and Caprylic/Capric Triglyceride improve spreadability and ensure even film formation for consistent protection. Lipid-supportive ingredients help maintain barrier integrity and reduce moisture loss.

Biological effect:

• Reduces UV penetration

• Helps prevent collagen breakdown and oxidative stress

• Supports long-term skin structure and elasticity

ENHANCE – SPF6 Radiance Layering & Optical Glow

Shimmering Sun Oil (SPF6)

A lightweight, multi-functional oil combining nourishing botanical lipids with zinc oxide (SPF6) and light-reflecting mineral pigments.

Key features:

• Delivers low-level sun protection suitable as a final layering step

• Enhances skin radiance and light reflection

• Rich in antioxidants and conditioning oils including jojoba, olive, avocado and sunflower oils

• Provides a non-greasy, luminous finish, particularly suitable for evening wear

Biological & visual effect:

• Improves surface hydration and lipid balance

• Enhances optical smoothness and glow

• Adds a finishing layer of radiance without compromising skin comfort

ENHANCE – Glow & Tone Optimisation

Glow Drops

A customisable radiance system enriched with botanical extracts and marine actives that help improve the appearance of skin tone and luminosity when mixed with moisturiser.

• Supports hydration through humectant pathways (e.g. glycerin, saccharide isomerate)

• Enhances skin appearance with optical and conditioning effects

• Designed to be mixed into daily moisturiser for a tailored glow effect

RESTORE – Barrier Hydration & Post-Sun Recovery

Algotherapy Body Lotion

A barrier-focused formulation combining marine extracts, lipid-rich emollients and humectants to support hydration and recovery after UV exposure.

Key ingredients such as Laminaria Digitata, Fucus Vesiculosus and Centella Asiatica help support skin resilience, while emollients and fatty alcohols reinforce the skin’s protective matrix.

Biological effect:

• Restores hydration balance

• Supports barrier repair

• Improves skin comfort and elasticity after sun exposure

Sun exposure triggers multiple biological pathways:

1. UV-Induced Collagen Breakdown

UVA penetrates into the dermis, activating enzymes that degrade collagen.

→ SPF50+ zinc oxide helps prevent this by reflecting UV at the surface.

2. Oxidative Stress

UV generates reactive oxygen species that damage cellular structures.

→ Mineral protection reduces exposure; antioxidants in oils support surface defence.

3. Barrier Disruption

UV increases transepidermal water loss, weakening hydration levels.

→ Lipid-rich formulations help maintain and restore barrier integrity.

4. Loss of Radiance

Dehydration and micro-inflammation reduce skin luminosity.

→ SPF6 oil and Glow Drops enhance light reflection and visible smoothness.

Result:

A multi-layered system that protects, enhances and restores – supporting both skin biology and visible skin quality.
