Sunscreen & how it works to protect our skin

Sunscreen shields the skin. It is essential for safeguarding the skin by blocking ultraviolet (UV) radiations of the sun. UVA and UVB are the two forms of UV radiation that harm us. UVA is always present and has the ability to penetrate deeper into the skin. It causes damage to the deeper skin layers, hastening the ageing process and raising the risk of skin cancer. Your skin requires protection year-round since UVA rays are strong all over the year. On the other hand, the strength and time of year of UVB radiation varies. They cause sunburns and skin cancer by harming the skin's outermost layers. On the sunscreen, a label named SPF is mentioned. It is known as the sun protection factor, that is a measure of how well the sunscreen protects against ultraviolet rays. Higher SPF means more protection from the sun rays.
You are exposed to the heat and the sun's damaging rays during the spring and summer, so you can wear sunscreen every day. But should you use sunscreen throughout the winter? The answer is that sunscreen should be worn every day of the year, even during the chilled winter weather. The sun's ultraviolet (UV) rays may not feel as warm or intense on your skin during the winter time but it continues to tear down the skin cells at a very fast rate resulting in a condition called photoaging. This will make you appear older than you are by hastening the development of wrinkles, sunspots, fine lines and discolouration. A sunscreen product blocks UV photons before they can harm the skin by acting like a very thin bulletproof vest. It has both inorganic and organic pigments. Inorganic molecules absorb, scatter, and reflect UV whereas organic sunscreen molecules absorb UV.
This winter, you can protect your skin as much as you can by:
  • Applying sunscreen on your exposed skin and even on your lips.
  • Wearing sunscreen 20 minutes before going outside.
  • Reapply sunscreen again at least every two hours.

Why You Should Wear Sunscreen in Winter

It's a big mistake to forgo sunscreen in the winter even if the sun rays might not feel as strong. No matter the weather, you ought to always use sunscreen. Here are some reasons why using it in the winter is extremely crucial:

Thin ozone in winters

The ozone layer is at its thinnest during the winter. This inevitably means that during this season, the ozone layer will absorb fewer ultraviolet (UV) rays and your risk of UV exposure will significantly rise. Therefore, your best defence against UV exposure throughout the winter is a sunscreen with a high SPF.

Anti- ageing benefits

The harsh winter climate makes your skin dry and dull. Your skin's collagen and elastin are harmed by UV rays, which accelerates the appearance of fine lines and wrinkles. It is therefore strongly advised that you apply sunscreen as it shows anti- ageing properties.

UV radiation is also caused by indoor lights

In winter months sun exposure may be lower and entails a larger reliance on electric lighting. However, the UV rays are also emitted by ambient, blue, and infrared lights. Increased UV exposure can also harm skin and raise the chance of developing skin cancer. Therefore, even if you are inside during the winter, it is crucial to use sunscreen.

Snow reflect sunlight causing sunburn

Higher the sea level, the greater the risk of UV radiation. Every thousand feet above sea level, UV radiation has been observed to increase by 5%. Even in the winters, you are at major risk of getting a sunburn due to the reason that snow actually reflects sunlight back at you. If you're in the mountains, remember to reapply sunscreen frequently.

Sunscreen loses its effectiveness more quickly in the winter

Sunscreen will wash off more quickly if you sweat in the summer heat, swim, or spend time on a sandy beach. As a result, you must frequently reapply. Many individuals are unaware that the harsh winter temperatures will also quickly decrease sunscreen's effectiveness. The effect of sunscreen reduces by wind, snow, sleet, and even the cold temperatures, so you should reapply often for maximum protection.

How To Choose The Right Sunscreen for Winter?

When including sunscreen in your daily skin care regime, factors to take into consideration are as follows:

Broad spectrum

Skin cancer and sunburn are both brought on by UVB radiation. In addition to this, photoaging and early skin ageing is caused by UVA rays. If your sunscreen is only protecting against one of the rays you are not getting full protection. Always look for broad spectrum sunscreen that gives protection from both UVA and UVB rays.

Water resistant

Choose water resistant sunscreen so that it protects you from the harsh wind and rain. Also, wear it during swimming or other physical activities involving sweating. There are some sunscreens that are extra resistant to water so they last more.

SPF 30 or higher

In the winters, it's crucial to choose a high level of protection because UVA radiation can still cause sunburn even when there are clouds in the sky. Applying a sunscreen with SPF less than 30 will provide insufficient coverage. Therefore always choose sunscreen with SPF 30 or more than that.
