For a good dose of Vitamin D, health experts have recommended getting sunlight in the morning, with the best time being 7am to 9am. Your skin naturally produces Vitamin D when it’s exposed to sunlight, therefore it’s vital that you get some sunlight in the early morning. That said, it can be harmful and damaging to your health and your skin if you’re exposed to sunlight when the sun’s UV rays are the strongest, which is between 10am to 4pm.
Unfortunately, there are still many people out there who could care less about applying SPF onto their skin for protection against the strong sun, thinking it couldn’t possibly bring them that much harm, but it does. Being exposed to UV rays can do a lot of damages on your skin and put your health at risk, like getting skin cancer. With SPF sunscreen, you’re minimising or even preventing the potential harms it could’ve otherwise caused. If you’re still not convinced about applying sunscreen with UV protection, perhaps you’ll change your mind after knowing these three reasons why you should use sunscreen everyday:
- Regular application of sunscreen can prevent dark spots and wrinkles
Those who are often exposed to strong sunlight without sunscreen as protection end up with ugly wrinkles and dark spots. In a 2013 research which compares skin ageing in 900 Australian women and men between 1992-1996, it was found that those who use sunscreen on a daily basis (by applying an SPF 15 and above to arms, neck, face and hands) had less or very minimal dark spots and wrinkles after about five years compared to participants who didn’t. In short, the participants who used sunscreen on a daily basis had 24% less skin ageing than their counterparts who didn’t. This shows that sunscreen can make us look young and protects us from skin cancer.
- Sunscreen can protect you from skin bagging and sagging
In another 2014 research, it was found that there’s a specific kind of UV radiation (which we’re all exposed to on a daily basis) called the UVA1 rays that can harm your skin cells. Participants who are exposed to UVA1 without sunscreen after only two days showed darkened skin with destroyed collagen. This means the UVA1 rays damages your skin by causing your skin cells to create molecules which can break your collagen – the vital skin protein you need to keep your skin youthful, smooth and firm.
- Nighttime hours are not a guarantee that you’re safe from UV damages
You might be thinking that when the clock strikes 7pm (or when the sky’s getting dark) you’ll be safe from sun damages, but you’re wrong. Surprisingly, while UV rays immediately damage your skin cells, other damages occur at nighttime hours after exposure to the sun. In a 2015 study, it was found that UV radiation damages your DNA immediately and continues to happen even hours later at night. However, researchers said that you can still apply sunscreen after sun exposure to minimise or prevent further damages.
If the points mentioned made you change your mind in using SPF sunscreen, how do you choose which one is the right one for you? There are so many types of SPF sunscreen in the market that it can get a little confusing.
As a rule of thumb, the lighter your skin tone, the higher SPF you’ll need, as lighter skin has less melanin which provides natural defense against UV rays. An SPF 8 can protect you for two hours, so higher SPF will protect you longer. Consider your needs and situation.
