# Which Sunscreen Should I Use? And Is Sunscreen Safe?

Many patients have asked me over the years, “Doctor, which sunscreen should I use?”

More recently, I’m hearing another question: “Is sunscreen actually safe?”

There is a lot on social media about sunscreen ingredients and possible links to cancer. So, here’s what I tell my patients.

In Australia, sunscreens are regulated by the Therapeutic Goods Administration (TGA). Sunscreens sold as therapeutic sunscreens must meet Australian standards for safety, quality and effectiveness.

The important thing to remember is that we have very strong evidence that UV radiation damages the skin and causes skin cancer.

UVA penetrates deeper into the skin. It contributes to skin ageing, pigmentation and skin cancer.

UVB is the main cause of sunburn and is strongly associated with DNA damage and skin cancer.

So what do I recommend?

I keep it simple: use a broad-spectrum SPF 50 or 50+ sunscreen.

Personally, I like sunscreens that contain zinc oxide. Zinc is a mineral UV filter that provides broad protection against UVA and UVB and is generally well tolerated.

But you don’t need to become obsessed with finding the “perfect” sunscreen. Choose one you like, because the sunscreen you actually use regularly is far more useful than an expensive one sitting in the bathroom cupboard.

And sunscreen isn’t everything. A hat, protective clothing and shade remain very important—particularly under the Australian sun.

My advice? Don’t let social media make you more frightened of sunscreen than of UV radiation. Protect your skin, keep it simple, and use sunscreen regularly.
