Sunscreen Friend Or Foe?

Yip, we’re entering the sunscreen debate and here’s what we’ve found: Sunscreen does not cause Skin Cancer (SC). There’s currently no scientific data, evidence or study to support that it does.

But the sun does cause most SC’s and there’s plenty of data to support this: UV exposure causes DNA damage in skin cells, which causes mutations that lead to SC. Getting sunburned at a young age increases your risk and is strongly associated with melanoma. Tanning is also a form of sun damage and contributes to the formation of SC.

Sunscreen helps to prevent SC, as shown in two Australian studies - melanoma was reduced by 50% and squamous cell carcinoma by 40% in those who wore sunscreen daily.

Good To Know:

Visible light and free radicals contribute to pigmentation issues like melasma. Iron oxides (the pigments used in tinted sunscreens), can help improve visible light protection. Zinc oxide is one of the most effective UV filters for coverage in the visible light range. Iron oxides are not enough on their own. MBBT is another strong option, while avobenzone offers very little protection.

Issues With Sunscreens:

1. Chemical Ingredients

Oxybenzone and octinoxate may disrupt hormones and harm marine life.

2. Skin Reactions

Increased demand for hypoallergenic and sensitive skin formulas.

3. Efficacy Mislabeling

Concerns about the accuracy of SPF ratings and claims on labels.

4. Environmental Impact

5. Application and Reapplication

Every 2 hours, regardless of whether you swim or not.

6. Consumer Education

How to choose the right sunscreen, including understanding broad-spectrum protection and the differences between chemical and physical sunscreens.

7. Sunscreen Expiration

8. Accessibility and Affordability

Access to quality sunscreens, particularly in lower-income communities.

These issues highlight the need for continued research, regulation, and consumer education to ensure effective and safe sun protection.

Tip:

Use sunscreen as part of a comprehensive sun protection strategy, which includes seeking shade and wearing protective clothing. But always do your research on the ingredients.
