What To Look For In A Good Sunscreen
Posted on: 30 May 2019
One of the best ways to protect yourself against sunburn is by avoiding the sun. Realistically, this isn't always possible. Spending time outdoors is often necessary for leisure and working purposes, which means you need to focus on other forms of protection. One useful approach is to find a good sunscreen. By putting a little research into the one you choose, your skin should stay healthier for your next visit to the skin cancer clinic.
Focus On UVA And UVB Rays
UVA and UVB rays have different effects on your skin. While UVA rays penetrate deep into the dermis, UVB rays affect the epidermis. Both result in sunburn, which increases your risk of different types of skin cancer.
As UVA and UVB rays increase your risk of different skin cancer types, you need protection against both. Before buying your sunscreen, read the bottle thoroughly and make sure it's UVA and UVB protective. Some manufacturers publish clinical data detailing how effective their products are against each type, which you can read before making your final decision.
Aim For A High SPF
At an absolute minimum, sunscreens sold in Australia must have an SPF of 4. However, if you're going to achieve broad coverage, you need 30 or above. SPF 30 sunscreens filter 96.7% of harmful rays. Choosing an SPF of 50 means you'll filter 98% of harmful rays.
Look For Waterproof Protection
It's unlikely you'll spend time in the sun and avoid sweating altogether. As such, it makes sense to choose a sunscreen that is waterproof. This becomes even more important when you're engaging in heavy outdoor work, sports, swimming or you plan on venturing into the sea.
Even when you do find a product that provides excellent waterproof protection, always re-apply it around every two hours. Additionally, make sure your skin is as dry as possible at the point of application so that it sinks into your skin appropriately.
Find The Easiest Mode Of Application
Finally, consider how easy it will be for you to apply the cream you're choosing. If you're spending time in the sun alone, you may find that using a simple cream doesn't achieve even results. In contrast, a spray may help you reach key areas such as your upper back. To achieve the best coverage, use a combination of application techniques. Additionally, when using products such as sunscreen sprays, avoid using them outside as you may find that windy conditions prevent the coverage you want.
