Most people are aware that using sunscreen can help shield them from the sun's damaging rays. Wearing sunscreen is a typical practice among people who spend a lot of time outside in the summer. What about the remainder of the year, though? What happens if you don't go outside much? One may ask: Is it necessary to wear sunscreen every day? Yes, to put it succinctly. Over time, sun damage accumulates even though you might not be aware of it. Additionally, you are exposed to ultraviolet (UV) radiation all the time, even if you don't spend much time outside. Applying sunscreen on a daily basis helps shield your skin from UV rays and their damaging effects.

Mineral vs. Chemical Sunscreen
Sunscreens made of chemicals and minerals protect skin in very different ways. Chemical sunscreens absorb UV rays and transform them into heat by penetrating the skin. These substances have the potential to degrade while being used and to cause skin irritation. This may not be the best option for sensitive skin.
Mineral sunscreens, such as titanium dioxide and zinc, on the other hand, disperse UV rays away from the skin. Imagine it as a protective layer that reflects sunlight away from your skin to block harmful UV rays.
Importance of Wearing Sunscreen
Here’s why wearing sunscreen every day is important.
Avoids Sunburn
UVB rays, which are responsible for the majority of sunburns, are blocked by sunscreen. The time of day and season have an impact on UVB intensity. Although it can burn you all year round, it is strongest at midday and in the spring and fall. You can still become sunburned on a cloudy day because UVB rays can pass through clouds.
Reduces the Chances of Sunburn
The DNA within skin cells is damaged by excessive UV exposure. Skin cancer may result from the unchecked growth and replication of aberrant skin cells. Sunscreen helps prevent cellular damage that can result in cancer by blocking UV exposure.
Prevents Premature Aging
UV rays break down the collagen and elastin in your skin. These proteins maintain the firmness and suppleness of skin. Over time, wrinkles, sunspots, sagging skin, and accelerated aging of the skin are caused by this damage to collagen and elastin. But sunscreen can prevent early aging and maintain overall appearance.
Minimizes the Appearance of Blotchy Skin
The tiny blood vessels in your face may become more noticeable if you are exposed to UV rays. This results in blotchy skin that doesn't go away and obvious red and purple patches. Daily use of sunscreen aids in the prevention of the formation of these swollen blood vessels.
Prevents Inflammation
Certain sunscreens have extra chemicals that may lessen UV-induced inflammation. Examples of anti-inflammatory sunscreen components that may help soothe skin disorders like rosacea and acne include vitamin E, aloe vera, and panthenol.
Maintains Skin Hydration
Hydrating elements found in certain sunscreens help maintain the integrity of the skin barrier while also hydrating the skin. Some moisturizing substances that are occasionally used in sunscreens are ceramides and hyaluronic acid.
The Appropriate Amount of Sunscreen
Generally speaking, you should apply a shot glass's worth of sunscreen to your body and two finger lengths to your face. Additionally, you should reapply every two hours or right away after perspiring or swimming.
Levels of Protection
We recommend SPF 30, which blocks up to 97% of UVB rays. Higher SPF numbers provide additional protection, but they don't contribute much more after that. SPF 15 blocks roughly 93% of UVB rays, SPF 30 blocks 97%, and SPF 50 blocks roughly 98%, according to comparisons of protection levels.
Re-application
Regardless of the SPF level, sunscreen should be reapplied every two hours or more frequently if you're swimming, perspiring, or towel drying.
Is SPF Really Necessary Every Day?
Even if you're not spending time outside, everyone six months of age and up should wear sunscreen every day, according to the Skin Cancer Foundation. This is because you are exposed to more sun than you think. In actuality, skin damage can occur after only 15 minutes of unprotected exposure. Therefore, wearing sunscreen every day is important.
How to Wear Sunscreen Correctly?
Apply a broad-spectrum sunscreen to protect yourself from UVA and UVB radiation.
Apply sunscreen 30 minutes before heading outside. This will allow your skin to have more time to absorb it.
Use enough sunscreen to ensure complete coverage. To use on the body, adults should use enough to fill a shot glass. Aim for a quarter-sized dollop for your face.
Remember your scalp (if exposed), lips, and ears when wearing sunscreen.
