Understanding scores

Not all sunscreen products are the same when it comes to sun protection and ingredient health hazards. The scoring system for EWG’s Guide to Sunscreens is designed to help the public find products that are safer, avoid ingredients of concern, and are more effective in reducing potential health harms from ultraviolet A and B exposure.

Every product in the guide gets a hazard and efficacy rating. The top scoring products have both a low hazard rating and an excellent UVA/UVB balance rating.

HOW WE DETERMINE SCORES

Hazard score

The hazard score, from 1 to 10, reflects known and suspected hazards linked to the ingredients. Beyond this 1 to 10 ranking, the EWG Verified® mark on a sunscreen means a product meets EWG’s strictest criteria for transparency and health.

Scoring legend
WEIGHT-OF-EVIDENCE APPROACH

A product’s hazard score is not an average of the ingredients’ hazard scores. It is calculated using a weight-of-evidence approach that factors in all of the hazards or health impacts associated with the ingredients.

EWG Verified Process

EWG Verified logo
EWG VERIFIED

Beyond the hazard score, the EWG Verified® mark on a sunscreen indicates that a sunscreen company’s ingredient disclosures show the product has met our full criteria to ensure it adheres to our strictest standards for efficacy, ingredient safety and transparency.

A SUNSCREEN CAN BECOME EWG Verified IF IT:
  • Meets EWG's criteria for overall product hazard score
  • Is formulated to provide balanced UVA/ UVB protection
  • Does not contain any ingredients on EWG's "Unacceptable" list
  • Discloses all ingredients, including those in fragrance.

TIPS

Sunscreen alone
is not enough

VIEW THE LIST

Wear clothes

Shirts, hats, shorts and pants shield your skin from the sun’s UV rays, reducing burn risk.

Plan around the sun

Go outdoors in early morning or late afternoon when the sun is lower in the sky.

Find shade - or make it

Picnic under a tree or take a canopy to the beach. Keep infants in the shade, reducing the risk of multiple burns by 30%.


Don’t get burned

Red, sore, blistered skin means you’ve gotten far too much sun.

Sunglasses are essential

Not just a fashion accessory, sunglasses protect your eyes from UV radiation.

Check UV index

The UV Index provides important information to help you plan your outdoor activities in ways that prevent sun overexposure.
