We hear a lot about the importance of sunscreens these days. Most of the people are including sunscreens as a part of their daily skin care regimen. Be it clothing or cosmetics, the SPF products seem to come in every form. With every passing day, modern cosmetic manufacturers are coming up with highly developed sunscreens that aim to provide you with more protection than ever before. In the present scenario, it can be really confusing to figure out what is actually true. Here we are providing you with some of the sunscreen facts and myths.
Sunscreen Facts and Information
- UVA and UVB: Before discussing the facts related to sunscreens, you need to have a basic understanding of UVA and UVB light. Both of this are the forms of UV (ultraviolet) light that can have adverse effects on your skin when exposed. UVA is a longer form of wave that penetrates into the dermis, the thickest layer of skin. Exposure to this can cause wrinkles, skin aging, and a suppressed immune system. UVB is a shorter wave that is mostly responsible for tanning of your skin i.e. sunburn. Frequent exposures may cause permanent damage and people may even develop skin cancer.
- Sunscreen Prevents your Body from Absorbing Vitamin D: Vitamin D is one of the vital nutrients for human health. Many people think that applying sunscreens every time prevent a person from getting ample vitamin D. This is one of the most common sunscreen myths. However, research indicates that a person needs about 15 minutes of exposure a day. Even if you are not able to get those 15 minutes of exposure, there are some foods such as cheese, fortified milk, tuna, salmon etc. that can also provide vitamin D.
- People with Dark Skin do not Need Sunscreen: No matter how dark or fair you are, using sunscreen is equally important. Regardless of the complexion, every skin has the potential to burn, to prematurely age, and to develop skin cancer if remain unprotected for long. UVB rays may protect the darker skin against damage to a certain extent. This is due to the melanin that acts to diffuse UVB rays. However, melanin cannot block UVA damage.
- You do not Need to Apply Sunscreen If you have a Makeup with SPF: Most of the people get excited at the idea of owning a makeup with SPF. Nowadays, most of the brands manufacture foundations, pressed powders, bronzers, blushers with SPF. Well, you need to stop being in a false sense of security. The SPF on these products may not provide you with enough coverage. Is not it a nice idea to double up your protection using sunscreens as well.
- You do not Need to Reapply Sunscreen If it is Waterproof: With the newest FDA guidelines becoming more stringent, companies now using the term ‘water resistant’, instead of waterproof. The companies must also designate how long the product is protective while sweating or swimming. One of the most important sunscreen need-to-know facts is that you must reapply your sunscreens at least every 2-3 hours. Apart from this, always opt for a sunscreen with a ‘broad spectrum’ label. This means the sunscreen protects against both UVA and UVB radiations.
- You cannot get Tanned while Wearing Sunscreen: Does sunscreen prevent tanning? Well, yes, sunscreen does prevent tanning. You may think that you do not need to apply sunscreen when you are sitting under a beach umbrella. But, the fact is the sand reflects 17% of UV radiation. Sunscreen will protect the skin from most of the rays, but some will reach your skin.
- Sunscreen Works Better than Covering Up: Many people believe that sunscreens can help them to stay protected throughout the day. However, the fact is, it is always advisable to cover up your skin with sunscreen clothing and a long-brimmed hat even if you use sunscreen. This will ensure an added protection.
- Sunscreens Never Expires: You need to understand nothing lasts forever and sunscreens are no different. Always check the expiration dates mentioned on the label or edge of the tube. An expired sunscreen will certainly lose its effectiveness over time.
With all the information regarding sunscreen facts and myths, it seems to be a no-brainer to understand the importance of using sunscreens. Make sure you use it every day, even if it is cloudy outside.
