Role of Sunscreen in protecting skin

We all know our skin is our first line of defense against germs, dirt, skin diseases, and the sun’s harmful UV rays. UV rays or ultraviolet rays of the sun are emitted at a frequency beyond the tolerance level of the human skin. This is why UV rays can cause eye problems, sunburn, premature aging, and, in severe cases, melanoma – skin cancer. 

Hence, it is imperative that we take good care of our skin by using sunscreen to protect it from the harmful ultraviolet rays of the sun. In fact, sunscreen’s role in skin care is currently more critical than ever in history because of environmental crises such as ozone depletion and climate change.   

This brings us to the question: 

Why is sunscreen important in skin care? 

However, before that, let’s learn how sunscreens work.  

How do Sunscreens Work? 

How do Sunscreen Work?

Sunscreens protect the skin from the damaging effects of ultraviolet (UV) radiation emitted by the sun by forming a protective barrier over it. There are two types of sunscreens – physical and chemical.  

Physical sunscreens contain active ingredients such as zinc oxide and provide broad-spectrum protection. Chemical sunscreens contain compounds such as avobenzone, oxybenzone, and various oxalates that are light on the skin and easier to apply.  

Sunscreens also have different SPF ratings. SPF, or sun protection factor, measures how much UV radiation is required to damage the protected skin. Hence, the higher the SPF rating, the better the skin protection.  

5 Reasons Why Sunscreen is Important for Skincare 

Sunscreens are highly effective in protecting our skin from the sun’s harmful rays, which can also affect us on cloudy days. 

Here are a few pointers on the role of sunscreen in skincare: 

Using Sunscreen Mitigates the Risk of Sunburn 

Dermatologists and skin/medical professionals worldwide emphasize the role of sunscreen in mitigating the risk of sunburn. The protective layer of sunscreens prevents premature wrinkling and skin cancer, common side effects of sunburns.  

Sunscreens Lower the Chances of Skin Cancer 

UV rays from the sun and tanning beds can cause mutations in the skin cells, causing skin cancer. Regular use of sunscreen with a proper SPF rating can significantly reduce the chances of skin cancer. The role of SPF in sunscreen is to determine the level of protection your skin gets from UV radiation. Dermatologists might take into consideration the duration of exposure to the sun. This factor helps them determine which type of sunscreen is best for your skin. 

Sunscreens Help Prevent the Signs of Ageing 

Prolonged exposure to the sun’s UV radiation can cause skin photoaging. It is a process in which the skin cells mature prematurely due to collagen breakdown. The role of sunscreens in preventing the signs of aging is significant, as the rejuvenating features of many modern sunscreens prevent leathery skin, discoloration, fine lines, and collagen breakdown.  

There are various procedures involving lasers that prevent the signs of aging. If you invest in such procedures, you must protect this investment by using the right sunscreen for your skin.  

Sunscreens Help Maintain an Even Skin Tone 

Exposure to UV rays can cause uneven skin tone and sunspots. Using the right SPF sunscreen can help even the skin tone. Sunspots are hard to get rid of, even with chemicals like retinol. Hence, the role of sunscreen is vital to prevent uneven skin tone.  

Sunscreens Reduce Inflammation 

Our skin can become painfully red and swollen when exposed to UV light. It is challenging for people suffering from skin conditions like psoriasis or rosacea. Regular and everyday use of sunscreen, especially physical sunscreens that contain zinc oxides, helps to reduce the risk of inflammation significantly.

Tips to Choose the Right Sunscreen 

Various products are available in the market, making it difficult to choose the right one for us. So, how do you decide which type of sunscreen is best for you

Check for Broad-Spectrum Protection 

As stated earlier, physical sunscreens provide broad-spectrum protection from the sun’s harmful UV rays. Opting for a broad-spectrum sunscreen is recommended because it protects against both UVA and UVB types of ultraviolet radiation.   

Choose Your SPF Wisely 

SPF measures how much UV radiation your skin can take without harmful effects. Taking this into consideration, sunscreens are formulated to provide optimum protection from the sun. The role of sunscreen in skincare is incomplete without a suitable SPF rating.  

An SPF 30 variant is often advised to use for daily activities since it protects skin from 97 percent of the UVB radiation.  

Consider Your Skin Type and Sensitivity 

Pick a sunscreen that is appropriate for your skin type. Look for formulations marked “for sensitive skin” or “hypoallergenic” if you have delicate skin or are prone to allergies. Physical sunscreens containing zinc oxide and titanium dioxide are often kinder and may be suitable for people with sensitive skin. 

Wrapping Up 

If skincare is a grand symphony, the role of sunscreen is that of the conductor. Sunscreen is your defense against the sun’s unseen forces, not merely a lotion you apply before spending the day at the beach.  

Its function broadly applies from shielding your skin from sunburns to long-term skin health protection. Sunscreen prevents early aging and the risk of skin cancer by providing a barrier against the damaging effects of UV radiation. 

Regularly using good sunscreen can significantly improve your skin and health and prevent health-related complications.
