The Hidden Dangers of Commercial Sunscreens and Why DIY Options Are a Safer Choice

Sunscreen has become a daily essential for many, especially during the warmer months. But while most people reach for the bottle thinking they’re protecting their health, they may actually be exposing themselves to ingredients that carry long-term risks. The truth is, not all sunscreens are created equal. Many store-bought brands contain chemicals that may do more harm than good, not only to your skin but also to your entire body.

If you're trying to live a more natural lifestyle or reduce your exposure to toxins, it may be time to rethink what you’re putting on your skin and consider making your own sunscreen at home.

What’s in Commercial Sunscreen?

A quick glance at the label of many popular sunscreen brands reveals a list of ingredients that can raise serious concerns. These often include:

Oxybenzone – A chemical that helps absorb UV rays, but it's also been shown to disrupt hormones. Oxybenzone can mimic estrogen in the body and has been linked to lower testosterone levels and reproductive issues.

Octinoxate – Another UV filter that may interfere with thyroid function and hormone balance. It’s also been banned in places like Hawaii for its harmful effects on coral reefs.

Retinyl Palmitate (a form of Vitamin A) – Under sunlight, this compound may speed up the development of skin tumors and lesions, according to some FDA reports.

Fragrance and preservatives – These are added to improve scent and shelf life, but many of them include phthalates or parabens that are known endocrine disruptors.

Nanoparticles – Some sunscreens use nano-sized zinc oxide or titanium dioxide, which may penetrate the skin and affect cells in ways we still don’t fully understand.

These ingredients are absorbed through the skin, and studies have shown that some of them remain in the body for days, even after a single use.

Why Your Skin Absorbs More Than You Think

Your skin is your largest organ, and it acts more like a sponge than a shield. What you put on it doesn’t just sit on the surface ... it can enter your bloodstream. This is why so many people with chemical sensitivity, autoimmune disorders, or hormonal issues often see flare-ups after using conventional skincare products, including sunscreen.

The irony is that while sunscreen is meant to protect you from harm, some commercial formulas may increase inflammation, disrupt your endocrine system, or contribute to long-term health challenges.

Why Homemade Sunscreen is a Safer Alternative

Making your own sunscreen gives you complete control over what goes on your skin. You can avoid synthetic chemicals and instead use ingredients that are not only safer, but nourishing.

Natural oils like coconut oil, shea butter, and raspberry seed oil contain some level of natural SPF. When combined with non-nano zinc oxide, which reflects UV rays rather than absorbing them, you can create a sunscreen that protects while also feeding your skin with vitamins and antioxidants.

Homemade sunscreen can also be tailored to your specific skin type, whether you need extra hydration, calming ingredients for sensitive skin, or a thicker balm for long outdoor days.

A Balanced Approach

It’s important to remember that some sun exposure is healthy. Your body needs sunlight to produce vitamin D, a hormone that supports immunity, mood, and bone health. The key is to avoid burning, not to avoid the sun entirely.

For extended time outside or on particularly strong UV days, DIY sunscreen made with safe, mineral-based ingredients can give you a layer of protection without the toxic load.

You don’t have to rely on store-bought sunscreen filled with questionable chemicals. With a few simple ingredients, you can make your own safe, nourishing sun protection at home. It’s one of the simplest ways to take charge of your health and protect your skin in the process. RECIPES 🌿 1. Shea Butter + Zinc Oxide Sunscreen
