How to Find the Best Sunscreen

BY: Editors | May 15, 2017

By the power of sunscreen, you can work and play outdoors without suffering from sunburn or premature signs of aging, all the while minimizing your risk of skin cancer. Due to increasing awareness of the importance of sunscreen, it's now ubiquitous, available as the classic white lotion and present in everything from makeup to moisturizer to clothing.

Yet with so many different types of sunscreen in varying SPF levels available, it's tough to know which is the best sunscreen for your skin. Below, we created this helpful sunscreen buying guide so you know what to look for.

Sunscreen SPF

For most people, SPF (sun-protection factor) is the first thing considered when shopping for a sunscreen. The number indicates how well the product protects your skin against UVB rays, the type of radiation that causes sunburn.

Most skincare experts recommend using a product that has an SPF of at least 15, though people with fair skin or certain skin conditions may want to use a sunscreen SPF of 30 or higher.

Does higher SPF mean stronger protection?

Yes, but as the SPF number climbs, you get diminishing returns on your UVB protection. For instance: SPF 15 sunscreen blocks 93% of UV rays, SPF 30 blocks 97%, and SPF 50 blocks up to 98%.

What is broad-spectrum sunscreen?

Broad-spectrum sunscreens are key to skin-cancer prevention, and they help you maintain your skin's health and youthful appearance. They protect skin from both UVB and UVA rays. While UVB rays are responsible for sunburn, UVA rays cause premature signs of aging like wrinkles and age spots. Both types are harmful and can lead to skin cancer. Look for sunscreens, whether physical or chemical, with a mention of broad spectrum on the label.

Sunscreen Ingredients

Besides taking SPF into consideration, you'll also want to decide if you'd rather use a chemical or a physical sunscreen. What's the difference? Simple: a chemical sunscreen works by absorbing UV rays when they hit your skin, while a physical sunscreen serves as a physical barrier between your skin and the UV rays. This is why you might hear physical sunscreens referred to as "sunblocks."

Chemical Sunscreens

Kiss My Face Suncreen Face Factor SPF 50 ($15.71)

Ingredients to look for: oxybenzone, octinoxate, octisalate, and avobenzone

Pros:

Easily absorbed, so they're less likely to leave a filmy residue on your skin
Penetrate skin rather than sit on top of it, so you're less likely to have holes in your coverage

Cons:

May be irritating to those with sensitive skin
Need time to absorb before working, typically around 20–30 minutes
Can dry out skin and clog pores

Physical Sunscreens

Drunk Elephant Umbra Sheer Physical Defense Sunscreen SPF30 ($29.99)

Ingredients to look for: mineral-based ingredients such as zinc oxide and titanium dioxide

Pros:

Less likely to irritate skin
Starts working as soon as it's applied
Most are naturally broad spectrum

Cons:

Formulas are often thicker and harder to rub in
Rub off easier and need to be reapplied more frequently
May leave white marks on skin and clothing and can be hard to wear under makeup
Must be applied generously, since gaps in molecules can let UV rays in

Types of Sunscreens

Once upon a time, thick, gooey, white sunblocks were the only option. These days, though, lotions are lighter and easier to wear than ever, while the selection of sun-shielding products also includes sunscreen gels, sprays, moisturizers, and even makeups formulated with SPF. Here, we pick apart the three most common forms you're likely to come across.

Lotions

The Healthy Sunscreen Sport Luxe Face & Body Cream SPF 30 ($29.99)

Pros:

Creamy formulas may help hydrate skin (depending on the ingredients)
White color makes it easy to see where you're applying, so you're less likely to miss spots

Cons:

May easily come off with perspiration
Can leave white marks on clothes

Gels

Pros:

More resistant to perspiration; an excellent sunscreen to wear while exercising
Dries fast
No white marks on skin or clothing

Cons:

Usually clear, so more likely to miss spots during application
Must be frequently reapplied

Sprays

Alba Botanica Very Emollient Sunscreen Sport Spray ($14.20)

Pros:

Fast drying and non-greasy
Applies quickly
Easy to apply to hard to reach areas, such as the back or shoulder blades

Cons:

Hard to see where you're applying
May contain alcohol, which can dry out or irritate skin

Sunscreen for Kids

ThinkBaby ThinkSport for Kids Sunscreen SPF 50+ ($16.56)

There are special circumstances to consider when choosing the best sunscreen for kids. For example, kids often have sensitive skin, so a mineral-based sunscreen with zinc oxide and titanium dixoide might be best if irritation is a concern.

But consider how you'll be using sunscreen on your child as well. Are you worried about sun exposure while swimming? If so, you'll want water-resistant sunscreen, and you'll want to reapply it often. According to the FDA, sunscreen is "water resistant" when it stays effective after 40 minutes in the water and "very water resistant" after 80 minutes.

Also: if you and your kids are going to be outside for a long time, a spray sunscreen might be the most convenient, since it's easy to reapply every few hours. Just make sure you cover every spot!

Sunscreens by Skin Type

For oily skin: Try a lightweight, water-based formula with ingredients like silica or isododecane, which help absorb oil rather than add to it with plant extracts or fatty acids.

Try: EltaMD UV Physical SPF 41 ($35.25)

For dry skin: Try a moisturizing sunscreen with ingredients like lanolin, dimethicones, or other oils.

Try: PCA Skin Hydrator Plus Broad Spectrum SPF 30 ($24.90)

For fair skin: It's all about consistent coverage. Be sure to reapply frequently, especially if you're being active.

For dark skin: Chemical sunscreens blend easily into all skin types to provide invisible coverage (physical sunscreens can appear chalky on dark skin).

For mature skin: Look for ingredients such as retinol, peptides, and plant extracts, which may stimulate collagen production and even out skin tone. Antioxidants can also help to reduce lines and spots.

Try: Prevage SPF 30 Anti-Aging Moisture Cream Broad Spectrum Sunscreen ($34.99)
