Blue light: A type of visible light that makes up about ⅓ of the light we can see. The primary source of blue light is the sun, but it can also come from TV screens, computer monitors and smartphones. Blue light can contribute to visible signs of aging like skin pigmentation and dark spots.

Broad spectrum: An SPF labeled “broad spectrum” protects against both UVA and UVB rays.

Chemical SPF: A type of sunscreen that works as a sponge to absorb UV rays. Chemical sunscreens can be formulated to leave no white cast and are a great option for all skin tones.

Epidermis: The outermost layer of your skin.

Hyperpigmentation: According to Dr. Deirdre Hooper, hyperpigmentation is dark patches on the skin that can be triggered by trauma, acne and UV damage.

Mineral SPF: Also known as “physical” SPF, mineral sunscreens contain mineral actives, such as titanium dioxide or zinc oxide, that sit on top of the skin (like makeup!) and work as a physical shield to block UV rays. They can never be 100% invisible but can be formulated to be sheer and blendbale. Plus, they can be a great option for those with sensitive skin.

SPF: Sun Protection Factor, which is the measure of protection from the sun’s UVB (burning) rays.

SPF 30: The minimum amount of daily SPF protection you should be wearing; it helps protect your skin from approximately 97% of UVB rays.

SPF 50: Helps protect your skin from approximately 98% of UVB rays.

SPF >50: Anything over SPF 50 won’t protect your skin from that much more of the sun’s rays and may give a false sense of all-day protection.

Sun damage: What can happens to your skin when it goes unprotected against UVA and UVB rays. It typically refers to signs of aging and/or skin cancer.

UV radiation: Invisible rays that come from sources like the sun.

UV index: A numbered scale from 1 (low) to 11+ (extremely high) that measures the expected risk of overexposure to the sun’s UV rays.

UVA rays: Also known as aging rays, these rays can cause signs of premature skin aging like wrinkles and age spots. They maintain the same strength all year round, and can even shine through clouds and windows.

UVB rays: Also known as burning rays, these rays can cause skin damage like sunburn, blistering and skin cancer.

Vitamin C: A powerhouse ingredient known to help visibly brighten skin. Vitamin C breaks down when exposed to the sun, so is only truly effective when worn with SPF.

Vitamin D: A nutrient that helps build and maintain healthy bones. Contrary to popular belief, vitamin D can be obtained from many other sources in addition to the sun (like your diet!).

Do Supergoop! products provide broad spectrum protection?
Of course! All of our products provide broad spectrum protection from both UVA and UVB rays.

If I wear SPF 30 and SPF 15 does it add up to SPF 45?
SPF numbers don’t “add up” — your skin is only protected by the highest amount of SPF that you put on. So if you apply both an SPF 15 and an SPF 30 then the highest amount your skin will be protected by is the SPF 30.

Do I need to wear SPF indoors?
Yes! The sun’s UVA rays (also known as “aging” rays, which can cause signs of premature skin aging like wrinkles and age spots) can shine through clouds and windows.

Why do I need to reapply SPF?
Sunscreens wear off throughout the day and some can be broken down by the sun’s rays. That’s why it’s important to reapply sunscreen at least every two hours, or immediately after toweling or being in water.

If I have to reapply SPF every two hours, does that countdown start when I first apply my sunscreen or when I go out into the sun?
You should reapply SPF at least every two hours starting from when you first apply it! For example, if you were to apply SPF at noon and then go outside at 1pm, you would need to reapply at 2pm (two hours after application, not two hours after going outdoors).

Are Supergoop! products cruelty-free?
Absolutely! Since day one, we have never tested on animals. Moreover, nearly all of our products are vegan, meaning they're not formulated with any animal byproducts. You can learn more about our ingredients here.

Can mineral SPF be invisible?
Nope! While mineral sunscreens can be sheer and blendable (like our Mineral Unseen Sunscreen SPF 40), they can never be 100% invisible. This is because they’re made with mineral actives, which are white powders that sit on top of the skin and work as a physical shield to block UV rays.

What’s the difference between mineral and chemical SPF?
The primary differences between chemical and mineral sunscreens are their active ingredients and how they protect your skin from UV rays. Get the breakdown below!
