AUREVIA SUN / THE GUIDE
A clear guide to sunlight, SPF and building a sun care routine that fits your day.
01 / THE SPECTRUM
Sunlight contains ultraviolet radiation, visible light and infrared radiation. They are different parts of the spectrum, with different evidence and ways of measuring their effects.
What it is: Ultraviolet light at approximately 315–400 nm. It reaches us throughout the year, including on cloudy days, and some UVA passes through ordinary window glass.
Skin effects: UVA reaches deeper into skin than UVB. It contributes to visible ageing and can damage DNA, adding to skin-cancer risk.
What it is: Ultraviolet light at approximately 280–315 nm. Its intensity varies with time of day, season and location.
Skin effects: UVB acts mainly in the outer layers of skin. It is the primary cause of sunburn and contributes to DNA damage and skin-cancer risk.
What it is: The higher-energy end of visible light, often discussed around 400–450 nm. Sunlight is a much stronger everyday source than typical screens.
Skin effects: Research links visible light exposure to persistent pigmentation, particularly in darker skin tones. SPF alone does not measure visible-light protection.
What it is: Infrared-A, approximately 780–1,400 nm, is part of sunlight’s infrared spectrum and contributes to the warmth we feel.
Skin effects: Laboratory studies have found changes in pathways linked to collagen breakdown. The impact of normal everyday solar exposure remains under study. SPF does not measure IR-A protection.
A product’s SPF rating does not establish HEV or IR-A protection. Check each product’s own information for its stated protection.
02 / THE NUMBER
Both can be part of a daily sun care routine. A higher SPF provides more protection against sunburn when applied correctly, but the number is not a timer for how long you can stay in the sun.
Using enough product, covering all exposed skin and reapplying it matters as much as the number on the pack.
An option for everyday use when paired with shade, clothing and regular reapplication.
A higher SPF option for people who want additional sunburn protection during outdoor activities.
03 / EVERYDAY PRACTICE
Sun protection works best as a combination of habits, not a single product.
Cover exposed skin evenly before going outdoors. Follow the directions on your chosen product, including the instructions for children.
Reapply at least every two hours outdoors, and after swimming, sweating or towel-drying. Check the product label for specific directions.
Seek shade when UV is strongest. Add protective clothing, a broad-brimmed hat and sunglasses when spending time outside.
Spray enough to cover exposed skin, then spread evenly. For the face, spray into your hands first and apply while avoiding the eyes. Avoid inhaling the spray.
04 / THE RANGE
Choose a texture and application format you will use consistently. These are guides to the formats described for each product.
| Product | Protection | Format | Consider it for |
|---|---|---|---|
| Essential | SPF 30 | Lightweight lotion | Everyday face and body use |
| Advance | SPF 50 | Lotion | Daily and outdoor face and body use |
| Mineral+ | SPF 50 | Hybrid mineral fluid | Those who prefer a fluid, dry-touch finish |
| Sport | SPF 50 | Cream-gel spray | Active days and outdoor use |
| AirLight | SPF 50 | Clear spray | A lightweight, dry-feeling spray |
| After Sun | No SPF | Cooling gel | Moisture and comfort after time outdoors |
| Aurevia Everyday | SPF 50 | Spray | Everyday sun protection |
05 / COMMON QUESTIONS
It means the sunscreen is designed to protect against both UVA and UVB radiation. Check each product’s label for its stated protection.
No. SPF is not a measure of hours outdoors. Apply enough of either product and reapply according to its directions.
UV can still reach you when the sky is cloudy. Use the UV Index and your planned time outdoors to guide your protective habits.
No. Water resistance does not mean a sunscreen stays in place indefinitely. Reapply after swimming, sweating or towel-drying as directed.
No. After Sun helps skin feel comfortable after outdoor exposure, but it does not provide SPF protection.
