Let's chat SPF
Although both sunscreen and sunblock are both effective ways of protecting your skin when outside and in the sun, there are a few things to keep in mind when choosing the right one for you. The most important thing to look for in your skin protectant is that it says broad spectrum on the bottle, this could be on either one but means that it protects against harmful UVA and UVB rays. The real difference between the two is in how they protect your skin from the sun and their ingredients.
Sunscreen works in such a way that it uses a reaction of the organic chemical compounds such as octyl methoxycinnamate, octyl salicylate, and ecamsule. This chemical reaction astoundingly enough actually turns the UV light in to heat so that it can be released from the skin instead of absorbed by it. There are also some other ingredients in sunscreen such as PABA (para-aminobenzoic acid) which can affect sensitive skin or cause reactions.
Alternatively, sunblock sits on the surface of the skin and as the name suggests actually creates a barrier layer to physically block the UV rays from getting to your skin. The opaque and thicker consistency which makes it harder to spread across the body comes from mineral ingredients like titanium dioxide or zinc oxide which unlike the chemical ingredients in sunscreen, are a lot easier on even the most sensitive skin types.
So even though sunblock may not be the easiest to put on or cause some white streaks and not always look the best it is going to protect your skin better. If these factors are going to result in you not putting it on as often then rather opt for sunscreen as most dermatologists recommend wearing a sun protectant year round as UV rays can still get to you through the clouds. To conclude, there is no right or wrong when it comes to these options, only what works best for you!
