Skin cancer continues to be among the most commonly diagnosed cancers globally. Dermatologists report that using sunscreen is one of the easiest and most powerful ways to prevent skin cancer. While many only think of sunscreen when they are going on vacation, or when they are enjoying themselves outside in the summer, health experts stress that sunscreen needs to be applied daily, in order to prevent possible long-term risks.
The Relationship Between Ultraviolet Rays and Skin Cancer
The sun emits ultraviolet (UV) rays, which are one of the leading causes of most skin cancers. UVA rays penetrate the skin most deeply and can cause cellular alteration, leading to the development of melanoma. UVB rays are most often responsible for the development of sunburns and non-melanoma cancers. The more unprotected exposure to either of these UV rays that an individual undergoes only harms the DNA in their skin cells over time, which increases the chances of DNA mutations turning into skin cancer.
The Importance of Sunscreen
Sunscreen works by absorbing or bouncing back and deflecting harmful UV rays, so that they do not harm the skin tissue. Broad-spectrum sunscreens are highly recommended (as they protect against both UVA and UVB rays). Research consistently shows that those who wear sunscreen regularly not only lower their risk for skin cancer but also have fewer signs of premature aging, such as fine lines, sunspots, and uneven skin tone.
Professional Advice
The American Academy of Dermatology recommends using a sunscreen with an SPF of 30 or higher and reapplying at least every 2 hours if you are outside, or sweating, or in water. They also recommend using plenty of sunscreen on all exposed skin, including areas that are easy to forget, such as your ears, neck, and the backs of your hands. Also, sunscreen should not replace other prevention habits, such as wearing a hat, sunglasses, and seeking shade when the sun is at its height.
Consumer Questions
With so many offerings, consumers often ask which sunscreen is the best. "Is Sun Bum sunscreen safe?" is a frequent question that highlights a desire for clearly written guidance. Dermatologists like to stress that the safest sunscreen is one you are frequently applying to your skin, as long as it is:
• Broad-spectrum
• Appropriate SPF for your skin
• Day to day sunscreen for your skin type.
Conclusion
Experts agree on this point; sunscreen is a significant part of skin cancer prevention. Applying sunscreen every day, no matter what the weather, will significantly lower risk of exposure to harmful UV rays and long-term damage to your skin integrity. By ensuring that you are using the right sunscreen and applying it the correct way, you are ultimately protecting not just your appearance, you are protecting your health.
