FREQUENTLY ASKED QUESTIONS

REYS is a science-backed dietary supplement designed to support your skin from within. It works alongside sunscreen by providing internal antioxidant and cellular support that topical SPF can’t reach. REYS helps defend against sun-related oxidative stress while supporting skin resilience, barrier function, and overall skin health over time.*

Up to 90% of visible skin aging is linked to sun exposure, making sun protection one of the most important investments in long-term skin health and appearance.

REYS is formulated for individuals who are sensitive to the sun, maintain active outdoor lifestyles, or prioritize skin longevity. By supporting the skin from within, REYS complements topical sunscreen and helps reinforce the skin’s natural defense and recovery processes over time.*

Most supplements focus on general wellness. REYS is targeted skin support.

Formulated in consultation with dermatologists, REYS uses clinically studied ingredients selected specifically for UV resilience, antioxidant defense, and skin longevity. No generic beauty blends, no unnecessary fillers, just purposeful ingredients designed to support how skin responds to sun exposure.*

While other companies have proprietary blends that make it a mystery to know what's in it, REYS wants you to know. REYS is powered by five science-backed ingredients selected to help protect skin from within while supporting long-term radiance, resilience, and overall skin health.

• Polypodium Leucotomos Extract (PLE)
  A fern extract clinically studied for its ability to help defend against UV-induced stress and support the skin’s natural inflammatory response.*
• Astaxanthin
  A potent antioxidant that helps support skin elasticity, hydration, and protection against visible signs of photoaging.*
• Niacinamide (Vitamin B3)
  Clinically studied to support skin barrier function, improve texture and elasticity, and help reduce the appearance of fine lines and uneven tone over time.*
• Vitamin C
  An essential antioxidant that supports collagen production, brightens the appearance of skin, and helps defend against environmental stressors.*
• Pomegranate (Punica granatum) Extract
  Rich in polyphenols that enhance antioxidant activity and work synergistically with PLE and astaxanthin to strengthen overall skin defense.*

Want to know more? Deep dive into the science.

Yes. Every active ingredient in REYS is supported by clinical research for safety and efficacy. We use dermatologist-approved doses that have been studied for their effects on UV defense, inflammation, and collagen preservation.*

Check out the clinical research in our science page.

When UV rays hit your skin, they create free radicals which are unstable molecules that cause oxidative stress and damage collagen. Antioxidants neutralize these free radicals, helping your skin stay calm, hydrated, and more resistant to environmental stress.*

Think of antioxidants as a shield that stops your skin from “rusting.” Just like metal oxidizes when exposed to air and moisture, your skin cells can oxidize under UV rays and antioxidants keep them stable and strong.

REYS supports your skin’s natural defense systems from the inside out. When your skin is exposed to sunlight, UV radiation triggers oxidative stress, inflammation, and cellular damage that can accelerate visible aging and compromise long-term skin health.

REYS is formulated with clinically studied, antioxidant-rich ingredients that work on multiple biological pathways involved in sun-related skin stress:

1. Neutralizes free radicals*
   UV exposure generates unstable molecules (free radicals) that damage collagen, elastin, and skin cells. REYS helps counter this oxidative stress with powerful antioxidants that protect skin at the cellular level.*
2. Calms sun-induced inflammation*
   Sunlight activates inflammatory responses in the skin that lead to redness, sensitivity, and long-term damage. Key ingredients in REYS help regulate this response, supporting a more balanced, resilient skin reaction to sun exposure.*
3. Supports cellular protection and repair*
   Ingredients in REYS have been studied for their ability to reduce UV-related cellular damage and support the skin’s natural repair processes—helping maintain healthier skin over time.*
4. Helps strengthen the skin barrier and overall skin health*
   By supporting hydration, elasticity, and barrier function, REYS helps improve how skin responds to environmental stressors, including daily sun exposure.*

Importantly: REYS does not block UV rays or replace sunscreen. Instead, it works as an internal layer of protection that complements topical SPF and protective clothing.

REYS can be taken daily or as needed, but consistent use delivers the greatest benefits over time. For optimal results, we recommend one of the following approaches—listed from most effective to least:

1. Daily Use (Most Effective)
   Take one serving each morning as part of your daily routine. Regular use allows the benefits to build, supporting long-term skin health and resilience.
2. Trip Prep
   Take one serving daily for 1–2 months leading up to travel, outdoor events, or periods of increased sun exposure to help prepare your skin in advance.
3. Day-Of Use
   Take one serving 1–2 hours before sun exposure. If you’ll be in the sun for an extended period, we recommend a second serving later in the day to maintain optimal support.

REYS begins supporting the skin’s natural defense processes after your first dose, with individual response varying based on skin type, tone, and sun sensitivity. With consistent daily use, longer-term benefits of improved skin resilience, barrier function, and overall skin health can be noticeable in as little as four weeks.

Yes! REYS works best with consistent use. Building antioxidant levels in your system helps your skin maintain year-round protection and radiance.*

Yes. On high-exposure sun days, we recommend taking up to four capsules total: two in the morning and two later in the day for extra defense.*

Yes. Just like sunscreen, REYS is designed for daily, year-round use. Sun exposure and environmental stressors don’t stop when summer ends—they can occur on cloudy days, through windows, and even during colder months. Taken consistently, REYS provides ongoing inside-out support to help maintain healthy, resilient-looking skin all year long.*

Store REYS in a cool, dry place away from direct sunlight. Keep the lid tightly closed to preserve freshness and potency.

No sunscreen is still essential. REYS is the layer you add underneath that supports your skin from the inside while SPF protects the surface.

No. REYS doesn’t affect your skin’s ability to tan. It simply helps reduce the damage, redness, and dehydration often caused by UV exposure — so your skin stays balanced and healthy.

People with higher sun sensitivity often notice the effects sooner, such as calmer, more comfortable skin after sun exposure. For others, benefits may appear more gradually. With consistent daily use, REYS supports skin resilience over time, with improvements in overall skin balance, tone, and texture becoming more noticeable as benefits build.*

REYS is designed for people who are sensitive to sun exposure, live an active outdoor lifestyle, or are focused on long-term skin health and appearance. It supports the skin from within for those who want smarter sun care without changing how they live. If you are pregnant or breastfeeding, consult your healthcare provider before use.

In most cases, yes. Our formula is designed to complement but not compete with your daily routine. If you're on medications or other skin-related treatments, it's always a good idea to consult your doctor.

Absolutely. REYS is formulated for daily, long-term use using plant-based antioxidants and vitamins that your body naturally recognizes. In fact, the longer you take it, the stronger your skin’s defenses become.*
