If you expose too much to the sun, you will be a victim of tan. However, even if you avoid exposing yourself to the sun, it does not mean it will prevent tanning.
Even if we want to prevent sun exposure, we cannot stop ourselves from getting close to nature, visiting a park, or even spending some time at the beach. So, we get exposed to the sun and cannot hide from the sun’s rays.
However, several products ensure to protect from harmful UV rays. But the question is, does sunscreen prevents tanning? Are they outstanding enough and protect your skin from skin damage. Even though the sun gives us tan, it also helps produce Vitamin D, which is an essential aspect of our lives.
What Are SPF and SPF Numbers?
Skin cancer is mainly caused due to the sun’s UV rays. SPF or Sun Protection Factor is essential for protecting your skin against them. It is a factorial measurement that detects how much UV exposure is required for sunburn on the skin if it is wearing sunscreen.
If the SPF number increases, then the sunburn protection increases directly. In short higher SPF means better sun-protective clothing. With the help of this SPF value, you can find how much time you can stay under the sun’s rays without getting the effect of harmful UV rays.
Almost all people get sunburn before they reach the age of 18 due to sun exposure. The number of SPF can detect if the sunscreen product can protect the skin layer or not. However, four types of SPF ratings can prevent skin cancer.
SPF Factor 15
Such values indicate that the product is at least 93.3 % potent in absorbing or reflecting the UVB rays.
SPF Factor 30
It indicates that the sunscreen product is 96.7% effective in reflecting and absorbing the UVB rays.
SPF Factor 45
Products with an SPF value of 45 shows 97.8% effectiveness against UVB rays.
SPF Factor 50
These products have high SPF and are most potent since they have 98% potential to absorb or reflect the UVB rays.
However, choosing broad-spectrum sunscreen over the SPF value is more beneficial since it can protect skin from UVA and UVB rays. Also, you must know what an ideal SPF is and how and how to choose your SPF value.
If you stay for too long outdoors, it is recommended to use a higher SPF sunscreen. Since sunscreen prevents tanning, it is found that with an SPF rating of 30, only three percent of UVB rays can penetrate your skin. Moreover, if you apply SPF 50 sunscreen, only two percent of UVB rays can penetrate your skin.
How Does Sunscreen Work?
Mainly there are two different types of sunscreen. The sunscreen protects from UVA and UVB rays. The chemical sunscreens are mainly octisalate and oxybenzone, and they can help you from sun damage. These sunscreens act as barriers to the sun’s harmful rays, but they do not come without any harmful side effects.
Natural sunscreens have fewer side effects than chemical sunscreen. However, the products made with natural materials provide zinc oxide, which is better and gives an extra layer to the skin and stops the UV rays from reaching the skin.
The blocking agents in the natural sunscreen are designated as GRAS (Generally Recognized as Safe and Effective) and approved by FDA(Food and Drug Administration).
Does Sunscreen Prevents Tanning?
Some people like the skin tone when they start developing a tan. People start worrying when they wear sunscreen. However, you must know that sunscreen does not prevent you from tanning. There is no such thing that can protect your skin from tanning.
Wearing sunscreen will keep you away from sun exposure and protect your skin from harmful UVB rays since it can cause skin cancer. But it would help if you accepted that sunscreen is not stopping you from getting tanned.
Even the UVA rays that are stopped by the sunscreen trigger the production of Vitamin D in our body. The vitamin produced helps regulate phosphate and some amount of calcium levels. Though Vitamin D can keep bones, teeth, and muscles healthy, it is not required in massive amounts.
If you stand in the sun just for 30 minutes a week, the body can accumulate enough Vitamin D required to regulate calcium in our body. However, if you have many calcium-based foods, you do not need the sun’s UV rays to produce Vitamin D.
Can Sunscreen Prevent Sunburn?
Sunscreen products allow people to stay out of the sun for a longer time. However, sun protection cannot last long. Even a sunscreen with at least an SPF rating of 50 tends to lose its effectiveness quite fast. So, it would help if you reapplied the sunscreen frequently.
Often you can face sunburn due to reflection and scattering of UVB rays. It can damage the skin and cause premature aging. So, sunscreen does not only limit tanning, but it can protect your skin cells from UV light from getting sun damage.
How To Prevent Tanning?
There are many options that people can try to prevent sun tanning.
You can avoid UV exposure by scheduling your outdoor activities before 10:00 A.M and after 4:00 P.M.
Also, it would be best if you tried to avoid the sun by walking in the shade.
Even you can try fabricated clothes specially designed to protect skin from the sun’s UV radiation.
Try to wear a wide-brimmed hat. It helps cover the exposed skin of the head, face, neck, and ears and stops from getting tan.
