Is Sunscreen the Culprit? Debunking Myths and Promoting Safe Sun Care
Recently, there's been a buzz on TikTok about sunscreen potentially causing cancer. If you're concerned about whether your sun protection is safe, let's clarify the facts to help you make informed decisions.
Understanding Sun Exposure and Skin Cancer
Skin cancer rates are increasing and are currently the leading type of cancer in the US, largely due to sun exposure damaging our skin cells. Melanocytes activate when exposed to the sun, which some mistake as a "base tan" – a misnomer, as any tan indicates UV damage. This prolonged exposure leads to DNA damage in our skin cells, increasing the risk of various skin cancers such as squamous cell carcinoma, basal cell carcinoma, and melanoma, which this year alone caused 8,000 deaths.
The Role of Sunscreen in Skin Protection
The good news is that sunscreen offers a simple yet effective way to prevent this damage. Regular use not only prevents wrinkles and premature aging but also significantly reduces the risk of developing skin cancers. Choosing the right sunscreen is crucial – opt for a broad-spectrum product with at least SPF 30, ideally water-resistant.
Types of Sunscreen
There are two main types of sunscreen: chemical and mineral. Both are effective, but mineral sunscreens are often preferred for sensitive or acne-prone skin due to their gentle formulation.
Proper Application for Effective Protection
Applying sunscreen correctly is key. For the face and neck, use about three fingers' length of sunscreen. For the body, a shot glass or two tablespoons is sufficient. Reapplication is crucial, especially after sweating or swimming.
Debunking Recent Claims
Despite recent media attention, there is no scientific evidence linking oxybenzone, a common ingredient in chemical sunscreens, to cancer. In fact, not using sunscreen increases your risk of skin cancer, making regular use essential for protection.

By staying informed and prioritizing sun protection, you can enjoy the outdoors safely and maintain healthy skin for years to come.
