It’s a fact that wearing sunblock on a daily basis is one of the basic things that you can do to protect your skin from harmful UV rays, as well as prevent premature ageing signs. But, there are times where a sunblock can be bad for your skin. Here’s why. 

What Constitutes a Good Sunblock?

Let’s start with the basics…

A good sunblock should do the job of protecting your skin from UV rays being absorbed and causing many skin issues (pigmentations, wrinkles, spots). To achieve this you need one labelled “broad spectrum” – a sunblock that shields against UVA and UVB rays. UVA attacks the collagen fibres and tissues underneath the skin to cause them wrinkle, sag and spotty, while UVB is the one that causes your skin to burn.

Needless to say, both types of UV rays are no good, and overexposure to them can certainly put your wellbeing at risk in the long run.

Additionally, the sun protection factor (also known as SPF) is a key factor in whether a sunblock is good. The number (multiplied by ten) indicates how long you can stay outdoors underneath the sun until your skin starts to burn. So, for example, if your sunblock has an SPF15, you’re good to stay outdoors for up to 150 minutes before you start to burn. 

So…What’s a Bad Sunblock Then?

Okay, now to the bad news. When a sunblock is considered bad for your skin, it means the ingredients in the formula are harmful. 

One notable ingredient is oxybenzone, considered to be a very troubling ingredient…so much so that it was recently banned in Hawaii after discovering it is harmful to coral reefs. On your skin and in your body, it disrupts your hormones as it is a synthetic form of estrogen. Another ingredient that has similar effects to oxybenzone is octinoxate. This ingredient is also a  hormone disruptor that can be very damaging to your health. 

Avobenzone is another ingredient you need to look out for – it irritates the skin is not stable enough to provide adequate protection for your skin. Because of this instability, avobenzone needs to be mixed with some other concerning ingredients to make it “work”. Considering we have plenty of good ingredients to protect our skin, avoiding these ones should be a priority. 

Next time you’re shopping for sunscreen, make a note to look out for these three ingredients. A product that II highly recommend is the O Cosmedics Mineral Pro SPF 30+.  This offers not only sun protection for the skin (with a high concentration of zinc oxide; one of the highest compared to other formulas) but also works as a daily moisturizer with antioxidant resveratrol to calm and heals any inflammation. Perfect for anyone looking for a multitasking product that can save you time and space. Plus, Mineral Pro SPF30+ also comes in a tinted version if you prefer a light makeup look or to minimize the appearance of the white effect that is common with zinc oxide.
