The last blog post discussed many of the problems with topical sunscreens and sunblocks. This includes any sunscreens or sunblocks that may be in makeup. If your makeup or other skin products have an SPF (Sun Protection Factor), beware!
Here’s an overview of the primary dangers of sunscreens:
–Sunscreens block the production of Vitamin D
–Sunscreens really don’t protect you from UVA rays very well
–SPF ratings are extremely misleading. First of all, they only describe UVB protection, NOT UVA protection at all. But also SPF ratings are theoretical, produced in a lab where the amount of sunscreen used on the subject is copious. In reality, sunscreen users almost always use far less than the amount used in testing. Furthermore, sunscreen use often accompanies cavalier attitudes toward sun exposure–leading to longer exposure and more damage.
–Many active ingredients in sunscreens are unstable. These chemicals actually break down in the sun, forming free radicals that further damage your skin.
–Many sunscreen ingredients are also toxic, passing through your skin and into your bloodstream where they circulate throughout your body. Some of these ingredients can be poisonous, while others actually alter your hormonal levels.

The EWG Rated 1400 Sunscreens in 2010
Yet you may still feel you need to wear sunscreen in certain situations–and it’s probably better than getting burned!! The Environmental Working Group (EWG) reviewed 1400 sunscreen products and rated them all, recommending a small number of them. In order to ensure the sunscreen you purchase has the least amount of hazardous chemicals as possible, please check the following links for recommended products. You can also search for the products you currently use to see how they rate. But remember, there’s no substitute for avoiding prolonged sun exposure.

Frequently Asked Questions
Q1. What are the sunscreen hazards discussed by the Environmental Working Group (EWG)?
The Environmental Working Group (EWG) has raised concerns about certain sunscreen ingredients that may be absorbed into the body or contribute to environmental harm. Ingredients such as oxybenzone, octinoxate, homosalate, and octocrylene are frequently discussed because studies have explored possible hormone disruption, skin sensitivity, and ecological effects. EWG also emphasizes that some sunscreens may provide weaker UVA protection than consumers expect.
Q2. Why does EWG recommend mineral sunscreens?
EWG generally recommends mineral sunscreens containing zinc oxide or titanium dioxide because these ingredients are currently considered safer and more effective by many researchers and regulators. Mineral filters primarily sit on the surface of the skin and reflect ultraviolet radiation rather than being significantly absorbed. EWG reports that these ingredients also provide reliable broad-spectrum UVA and UVB protection when properly formulated.
Q3. What concerns does EWG have about high SPF sunscreens?
EWG states that extremely high SPF values can create a false sense of security because SPF numbers mainly measure UVB protection and not UVA protection. According to EWG’s research, SPF values above 50 provide only slightly higher UVB blocking while encouraging longer sun exposure. The organization recommends focusing on broad-spectrum protection, proper application, and reapplication rather than relying only on high SPF marketing claims.
Q4. Why does EWG caution against spray sunscreens?
EWG has expressed concerns about spray sunscreens because aerosol particles may be inhaled during application. Some spray sunscreens have also faced recalls due to contamination concerns involving benzene in recent years. In addition, studies cited by EWG suggest spray products may provide uneven skin coverage compared to creams or lotions, potentially reducing the level of UV protection users receive.
Q5. What sun protection recommendations does EWG provide besides sunscreen?
EWG recommends using sunscreen as only one part of a broader sun protection strategy. Additional recommendations include wearing hats and protective clothing, seeking shade during peak sunlight hours, avoiding sunburn, and using sunglasses to protect the eyes from ultraviolet radiation. The organization also advises consumers to reapply sunscreen regularly and avoid prolonged direct sun exposure whenever possible.
