Defend
Block what SPF can't.
- Helps neutralize UV-triggered free radicals before they damage healthy cells.*
- Supports your skin's collagen and barrier function under sun stress.*
- Reinforces the cellular layer SPF can't reach.*
Two capsules. Every morning. Before the sun.
Here's how REYS becomes the easiest, smartest thing on your counter — and how the science actually works once it's inside you.*
Shop the Suncare Capsule →Defend. Restore. Preserve.
A daily layer of inside-out support — three jobs, one capsule, every morning.*
Restore
Bounce back, daily.
- Supports your skin's natural recovery after UV exposure.*
- Helps maintain healthy-looking skin tone after long days outside.*
- Supports collagen synthesis and antioxidant balance from within.*
Preserve
Future-proof your glow.
- Supports the collagen and elastin that keep skin looking firm, smooth, and youthful over time.*
- Helps defend against the cumulative UV-driven stress that drives roughly 90% of visible skin aging.*
- Built for skin longevity — today's habit shows up in how your skin holds up years from now.*
Sunscreen on top. REYS underneath.
Wear both.
On the surface
Sunscreen.
Filters and blocks UV before it hits your skin.
From within
REYS.
Supports your skin's resilience at the cellular layer SPF can't reach.*
“Sunscreen is great for supporting the skin's surface, but UV rays can still cause stress deeper in your skin. [REYS] would add an extra layer of resilience.”— Dr. Akash A. Patel, Dermatologist
REYS doesn't replace SPF. Always pair with topical sunscreen — REYS is the layer underneath.
From sun to skin to defense — in four steps.
UV exposure starts a chain reaction inside your cells. REYS is built to interrupt it.*
Sunlight hits your skin
UV rays penetrate past the surface SPF can't fully block.
Your cells get stressed
UV exposure triggers oxidative stress at the cellular layer.*
Free radicals form
Unstable molecules that damage healthy cells, collagen, and DNA over time.*
REYS neutralizes them
Five clinically studied actives go to work supporting your skin's defenses from within.*
The hero active
A fern that learned to live in the sun — so your skin could too.
POLYPODIUM LEUCOTOMOSBorn in the rainforest.
Born in the rainforest.
Studied in the lab.
For decades, dermatologists have studied Polypodium leucotomos — a Central American fern with a remarkable, research-backed ability to support the skin against UV-induced stress from within. It's the quiet hero of the REYS formula, dosed at the level the clinical research used.*
- 300 mg clinical-grade dose in every serving
- 20+ yrs of peer-reviewed dermatology research
- 1 fern doing what topical SPF alone can't
Five clinically studied actives.
Meaningful doses, every one — backed by research, not a token sprinkle.
Polypodium leucotomos
300 mg
Helps neutralize UV-triggered free radicals at the cellular layer.*
Nicotinamide
500 mg
Supports DNA repair following UV exposure and reinforces the skin barrier.*
Astaxanthin
4 mg
A clinically studied antioxidant up to 6,000× more potent than vitamin C in some lab models. Works synergistically with PLE.*
Vitamin C
250 mg
Supports collagen synthesis and the skin's antioxidant defense.*
Pomegranate extract
100 mg
Polyphenols studied for their role in supporting skin cell protection and tone.*
