Sun Smart: Your Ultimate Guide to Safe and Savvy Sunbathing

Let’s face it, a sunburn isn’t just a painful nuisance; it can also put a damper on your summer fun. Sunburns often happen due to improper sun protection or not knowing how to apply sunscreen correctly. According to a 2015 survey, only a small fraction of people truly understand SPF ratings on sunscreen products. To help you achieve that perfect tan this summer while protecting your skin from harmful UV rays, we’ve put together a comprehensive guide to help you understand sunscreen labels better.

Understanding SPF

SPF stands for Sun Protection Factor. It’s crucial to know that the SPF scale measures protection against UVB rays only. UVA rays, which are also harmful, are indicated on the label with a special star symbol. The protection scale starts at 2, the lowest level, and goes up to 50+.

The ABCs of UV Rays

Understanding the different types of UV rays is essential for effective sun protection:

UVB (Short-Wave Ultraviolet B): These rays cause sunburns and damage the top layer of the skin, potentially leading to skin cancer. It’s essential to protect your skin from these rays to maintain a safe and healthy tan.
UVA (Long-Wave Ultraviolet A): UVA rays make up 95% of the UV radiation that reaches the Earth’s surface. These rays penetrate deep into the skin, affecting vital functions and contributing to aging and wrinkle formation. Like UVB rays, UVA rays can also cause cancer.
UVC (Short-Wave Ultraviolet C): UVC rays are the most dangerous of the three. Fortunately, they hardly reach the Earth’s surface as they are almost entirely filtered by the atmosphere.

SPF 15: The Universal Protection Level

SPF 15 is a universal protection level suitable for all skin types. Products with SPF 15 shield your skin from harmful solar radiation, not just giving you a golden hue. It’s not advisable to hit the beach or expose yourself to direct sunlight without first applying a cream with at least SPF 15, especially if you have sensitive or pale skin, to avoid skin damage. The British Association of Dermatologists recommends using SPF 30 and advises against using SPF 2 or 4.

Decoding Star Ratings

The star rating system indicates the level of protection against UVA rays, ranging from one to five stars. A four-star rating is the minimum protection you should look for during prolonged sun exposure. If the label says “medium” or “high” protection, don’t be confused; the number of stars will accurately indicate the level of protection. Research has shown that the necessary amount of sunscreen to apply to the body should be about two teaspoons for the face and two tablespoons for the body.

Proper Application and Timing

After applying sunscreen, you should wait about 30 minutes before going out into the sun. Many people make the mistake of applying sunscreen right before jumping into the water, which doesn’t give the cream enough time to absorb. Instead, it washes off as soon as your skin gets wet, leaving your body exposed to dangerous solar radiation.

Additionally, storing sunscreen on your cosmetic shelf for more than two to three years is not recommended, as the protective properties of the cream can diminish over time. An expired product can be as harmful to the skin as a cream that doesn’t protect at all. If you follow all precautions, you shouldn’t have much sunscreen left after the summer season.

The Most Dangerous Time for Sun Exposure

The period from 11:00 AM to 3:00 PM is the most dangerous time for solar activity. If you don’t want to subject yourself to serious consequences that go beyond just redness, you should spend these hours in the shade, enjoying the sunny landscapes from a safe distance.
