Everything you ever wanted to know about sunscreen
How does sunscreen work?
Sunscreen is a lotion, gel, stick or spray that absorbs or reflects some of the sun’s ultraviolet radiation. This UV radiation consists of two types of UV rays that damage our skin. The first are the UVB rays. These cause sunburn and can play a major role in developing skin cancer. The second type of rays are UVA rays which cause skin damage that leads to aging signs and wrinkles. Sunscreen protects your skin from these harmful ultraviolet rays.
The glorious benefits of sunscreen
Everyone can and should reap the benefits of sunscreen. Firstly, sunscreen minimizes UV damage and decreases your risk of skin cancers and skin precancers. According to The Skin Cancer Foundation, regular daily use of SPF 15 sunscreen can reduce your risk of developing squamous cell carcinoma (SCC) by about 40 percent and lower your melanoma risk by 50 percent.
Secondly, sunscreen helps prevent premature skin aging caused by the sun. A study found that everyday use of sunscreen can slow or temporarily prevent aging signs. So long wrinkles, sagging skin and age spots!
How to choose the right sunscreen?
The number 1 rule when choosing sunscreen is: pick the one you’ll actually end up using. However, there are a few things you should watch out for. For starters make sure your sunscreen offers broad-spectrum protection. Why? Because all sunscreens protect against UVB rays but not UVA rays. Only the ones labelled as “broad-spectrum protection” or “UVA protection” shield you from both. Another great tip is that you look for water-resistant sunscreen with SPF 30 or more – this will deliver a good amount of protection while lasting longer through sweating or swimming.
What about the right sunscreen for your skin type? You should know that there are two types of sunscreen. Sunscreens that reflect the UV rays are called physical sunscreens and the ones that absorb them are called chemical sunscreens. Generally, physical sunscreens are recommended to people with sensitive skin. Moreover, sunscreen comes in so many forms (lotions, creams, gels, ointments, sprays etc.). For dry skin, creams work best. For oily skin, try something less heavy-duty like a gel or spray.
Your time in the sun certainly don’t rely on sunscreen alone. It’s a great way to protect yourself from the sun but it’s not perfect. Limit your time in the sun. Avoid sunbathing from 11am to 3pm when the UV rays are most intense. Likewise, use hats and sunglasses or cover up with clothing. Don’t forget to reapply sunscreen, especially if you’re sweating or going into the water. If you end up getting a sunburn anyway, don’t panic. In case of a severe sunburn, definitively see your doctor.
