Sunscreen is a product you put on your skin to protect it from getting burned by the sun and to lower the risk of skin cancer.
Having fun in the sun is a wonderful way to bond with your family, boost your mental well-being, and replenish your body’s vitamin D levels. It’s essential to be mindful of the sun’s powerful ultraviolet rays, which can be damaging to your skin if not properly protected. Thankfully, sunscreen acts as a crucial barrier against these harmful rays.
Navigating the vast array of sunscreen options available can be overwhelming, making it challenging to decide on the best choice for you and your loved ones. It’s important to explore factors such as SPF levels, water resistance, and potential allergens when selecting a sunscreen that aligns with the unique needs of your family’s skin to ensure effective sun protection.
You can be confident in what you’re putting on your skin all year round by reading this article, which will explain the various types of sunscreen and which ingredients are safest and which ones to avoid.
What is sunscreen?
Sunscreen, also referred to as sunblock or sun cream, is a specially formulated product available in various forms like lotions, sprays, gels, and other topicals designed to either absorb or reflect the harmful ultraviolet (UV) radiation emitted by the sun. It serves as a protective shield for the skin against the detrimental effects of UV radiation, which is a type of invisible light originating from the sun. This radiation has the potential to cause skin damage and elevate the risk of developing skin cancer, underscoring the vital importance of using sunscreen as a preventive measure for maintaining skin health and reducing the likelihood of serious health concerns.
What is the meaning of SPF?
The acronym for Sun Protection Factor is SPF. The Sun Protection Factor (SPF) measures how long it takes for redness to appear on skin in comparison to the absence of any product. It is tested in a laboratory.
For instance, if it takes ten minutes for skin without protection to become red, then an SPF30 sunscreen applied correctly should theoretically take thirty times longer, or three hundred minutes, to burn. Achieving this level of protection in real life can be quite challenging due to the multitude of factors that come into play. These factors include, but are not limited to, one’s specific skin type, the intensity of UV radiation present, the effects of activities such as swimming and drying, as well as the quantity and proper application of sunscreen. The successful attainment of effective protection requires a careful consideration and management of all these variables.
How does sunscreen work?
To keep your skin well-protected from UVA and UVB rays, it’s essential to have broad-spectrum protection. Sunscreen products are specifically made to prevent sunburn. UV radiation causes your skin’s collagen and elastin to break down, which results in wrinkles and disturbs the regular growth and function of your cells.
Sunscreens work differently depending on the components of your UV filter. Some sunscreens absorb UV rays while others reflect them, providing varying levels of protection against the sun’s harmful effects. In order to prevent UV rays from damaging your skin cells, sunscreens containing chemical-based ingredients, like homosalate, work by penetrating into the uppermost layers of your skin. Sunlight-blocking minerals, such as zinc oxide and titanium dioxide, form a protective layer on the skin’s surface that reflects ultraviolet radiation away from the skin. Certain sun protection products combine mineral and chemical sun filters in their composition.
What does sunscreen made of?
Sunlight is absorbed by chemical sunscreens, which function like sponges. Among their active ingredients are oxybenzone, avobenzone, homosalate, octisalate, octocrylene, and octinoxate. When applying these formulations, you will notice that they are more user-friendly due to their smooth texture, making it effortless to blend them onto the skin seamlessly without the undesirable white residue.
Sunscreens with minerals in them function similarly to a barrier. Sunlight is reflected by them as they remain on the surface of your skin. A few sunscreens that are physical also block out the sun. Zinc oxide and/or titanium dioxide are the active ingredients found in physical sunscreen. If you have sensitive skin, go for this kind of sunscreen.
Types of sunscreens
Since practically every skin care brand sells sunscreen, we are aware that choosing a product can be confusing. Nonetheless, bear in mind this when you think about the suggestions that follow, there are two main varieties of sunscreen available:
- Physical: serves as a shield against the sun’s rays by sitting on top of the skin. Given that they are intended to remain on the skin’s surface, they can be challenging to massage in and may cause the skin to appear somewhat pale. Some even feature eye-catching colors that children find appealing. Physical sunscreen is immediately effective when applied, but it is easily removed by sweat or water.
- Chemical: create a thin protective layer that blocks UV rays before they reach the skin; this is also known as organic sunscreen, because it contains carbon. Heat is produced by it from the rays, which is subsequently released from the skin. It doesn’t leave the same white film on the skin as minerals do because it absorbs into the epidermis, and it also doesn’t wash off as quickly. However, it may take fifteen to thirty minutes to get going.
What are the benefits of sunscreen?
Using sunscreen daily is essential not only on sunny days but also on cloudy or overcast days as it provides vital protection against harmful UV rays, reducing the risk of skin damage and premature aging. The following are some advantages of wearing sunscreen every day:
- maintains the barrier of defense that covers your skin
Applying sunscreen to your skin on a daily basis can help strengthen its barrier of defense. Sunlight can still affect you even when you’re just taking a short stroll outside. The simplest approach to shield yourself from dangerous UV (ultraviolet) radiation, guard against unanticipated sunburns, and soothe your skin is to wear sunscreen every day. Furthermore, skin conditions like acne, rosacea, and eczema can all be made worse by prolonged sun exposure.

- minimizes skin cancer risk
You can greatly lessen your exposure to these harmful rays that can cause skin cancer by using sunscreen with a high SPF. UVB, or ultraviolet B rays are harmful and can cause sunburn as well as skin cancers such as melanoma, squamous cell carcinoma, and basal cell carcinoma. Sunscreen shields the skin from these harmful rays.
- aids in preventing early aging
One common tactic used by marketers is bombarding us with an abundance of advertisements aimed at convincing us to purchase anti-aging products. However, it is crucial to remember that an effective preventive measure against premature skin aging is diligent sun protection. Therefore, by shielding your skin from the harmful effects of the sun’s rays, you can significantly delay the signs of aging and maintain a youthful appearance.
Brown spots, wrinkles, and uneven pigmentation can all be avoided with regular use of sunscreen.
Should babies wear sunscreen?
Sunscreen is a must for all children. All children should use sunscreen with an SPF of 30 or higher, according to the American Academy of Dermatology (AAD). This applies to children of all skin tones. While tanning is an indicator of sun damage, dark skin has more melanin for protection and tans more readily than burns. Painful sunburns can also occur in children with dark skin.
Infants under six months old should not be exposed to the sun. Wear light clothing that covers your baby’s arms and legs when they go outside. A brimmed hat should also be worn. Apply a small amount of sunscreen to your baby’s exposed skin, such as their hands and face, if you are unable to protect them from the sun.
Additionally, set an excellent example for others. Your kids will learn good sun etiquette and you can lower your risk of skin damage by wearing sunscreen with SPF 30 or higher every day and limiting your time outside.
How long does sunscreen last?
Sunscreen fades and breaks down over time, even if you apply a lot of it. The secret to the best protection is to apply frequently and early.
Allow sunscreen to work for about half an hour before venturing outside because its active ingredients take some time to activate. Apply again no less than every two hours. Furthermore, put on new sunscreen every time you swim and towel off, even if the label claims it is waterproof.
When should I use sunscreen?
It is essential to remember to apply sunscreen daily on any exposed skin areas when spending time outdoors. This precaution is crucial as the sun’s harmful UV rays are present throughout the year. Even when the sky is overcast, almost 80% of these detrimental UV rays can still filter through the clouds. Therefore, protecting your skin with sunscreen is a proactive way to guard against potential sun damage and reduce the risk of skin-related issues in the long run.
Where should I use sunscreen?
All exposed skin, or any area that won’t be covered by clothing, should be heavily covered in sunscreen. People frequently overlook the following specific areas that need to be prioritized:
- Face: Use lip balm with SPF, protect the delicate skin around your eyes with sunscreen designed specifically for the face, and don’t forget about your ears.
- Neck: Remember to avoid getting sunburned on the back of your neck.
- Ears: Your ears’ backs and tips are exposed to the sun and are susceptible to burning.
- tops of feet: Sunscreen is also required here!
- Hands: Throughout the day, they are exposed to a lot of sun.
- Bald head or thinning hair: Wear a hat or slather your scalp in sunscreen to protect yourself.
How to apply sunscreen?
It is best to apply sunscreen 20 minutes before being exposed to UV radiation in order to create the desired protective barrier. To apply it on clean, dry skin, use a generous and even application.
Applying roughly 5mL, or one teaspoon, of the product to each arm, leg, front, back, and face—including the neck and ears—is advised for adults. For a full body application, that comes out to a total of 35mL, or roughly seven teaspoons.
Regardless of the sunscreen’s water resistance, it is always necessary to reapply sunscreen at least every two hours. Sunscreen should always be reapplied after swimming, sports, perspiring, and towel drying as these activities can diminish the product’s efficacy.
What kind of sunscreen is best?
Sunscreen is available in a variety of unique formulas, including sticks, gels, sprays, lotions, and creams. The sunscreen that you really use is ultimately the best.
Naturally, proper application is necessary for a sunscreen to work. Every square inch of exposed skin should have one ounce of sunscreen applied. Don’t forget to reapply every two hours or right away after intense perspiration or swimming. Save a nickel-sized dollop for your entire face.
For a more even application, spray sunscreen directly onto your hands and use your fingers to apply it to your face if you’re just using a spray bottle.
Additionally, when selecting the ideal sunscreen for you, a few lifestyle factors may also be taken into consideration.
- Sensitive or acne-prone skin: Pick an SPF that isn’t scented or dyed in the physical form. Acne-prone skin types are best served by products marked as non-comedogenic.
- Playing sports: Your sunscreen’s effectiveness may be diminished by sweating. A sport sunscreen is formulated to withstand sweat and provide longer protection.
- Spending time outdoors: Always go with the higher SPF if you spend a lot of time outside.
- Makeup and reapplication: Reapplying sunscreen after getting wet is advised every two to four hours. Select reapply-friendly sunscreen, like pressed powder or light moisturizing sunscreen, if you wear makeup.

Rather than rubbing the sunscreen in, try patting it on. This aids in preventing the white cast and ensuring even coverage.
Does sunscreen expire?
Sunscreen does, in fact, expire. According to the U.S. Food and Drug Administration (FDA) guidelines, sunscreen products must have an expiration date unless the manufacturer can demonstrate through stability testing that the product will remain effective for a minimum of three years.

In general, reapplying sunscreen is advised every two hours, particularly after perspiring or swimming. A second application might not be necessary if you work indoors and keep your desk away from windows.
Conclusion
It is crucial to prioritize the application of sunscreen on a daily basis to protect your skin from the harmful effects of sun exposure. Consider this invisible protection as your shield against sun damage, safeguarding you even when the sun’s rays catch you off guard. A good daily sunscreen routine that suits your needs should be in place. Speak with a dermatologist or healthcare professional if you’re unclear about the type of daily sunscreen that’s best for your skin.
Nonetheless, bear in mind that no sunscreen is 100% effective at blocking UV radiation. In addition to wearing sunglasses and a wide-brimmed hat, seeking shade and selecting clothing with built-in sun protection are other important aspects of good sun protection.
