Sunscreen
The sun’s ultraviolet (UV) rays can harm us significantly. From damaging the structure of our skin and
speeding up the aging process to damaging the DNA of our skin cells which can lead to skin conditions like
skin cancer. Therefore, in order to protect ourselves from harmful rays, we must use sunscreen, also
known as sunblock, regularly. It will protect your skin from sun’s harmful rays and skin conditions like skin
cancer, maintaining your general health.
Ingredients
Sunscreens include a variety of effective ingredients like Carbopol, glycerin, etc. Take a look at some of the ingredients in sunscreen.
-
Glycerin
This is a crucial ingredient in the majority of sunscreens. Glycerin is well known for having exceptional
moisturizing qualities. It draws water from the surroundings and the skin's deeper layers into the outer
layer since it is a potent humectant. This moisture-drawing capacity keeps the skin moisturized and helps
avoid flakiness and dryness. Since glycerin doesn't leave skin feeling greasy because some other
moisturizing ingredients do, it works well on a variety of skin types, including combination and oily skin.
Besides that, enhancing the skin's natural barrier is one of glycerin's most important skincare roles. This
barrier is crucial for defense against microorganisms, irritants in the environment, and other dangerous
materials. Glycerin helps strengthen this barrier by ensuring that the skin holds onto moisture, which
increases its resistance to outside aggressors. Using this ingredient on a regular basis may greatly enhance
skin texture. It helps smooth and soften out rough areas of the skin, leaving it feeling more even and
velvety, while continuously hydrating the face. -
Cetyl Alcohol
Thanks to its superior emollient qualities, cetyl alcohol is frequently included in many skincare
products like sunscreens. By forming a barrier across the skin's surface, it functions as an emollient, which helps to smooth and soften the skin.
By retaining moisture, this layer keeps the skin moisturized and stops water loss. Because of its
hydrating properties, cetyl alcohol is especially advantageous for dry, rough skin types, as it helps
to enhance the skin's suppleness and smoothness. Cetyl alcohol also has moisturizing properties along with thickening formulas for skincare products. It gives creams, lotions, and other items a desired consistency and facilitates application
by stabilizing and thickening them. Because of its enhanced texture, products apply more evenly and penetrate deeply into the skin,improving the user experience. Another amazing benefit of this ingredient is that it has a mild
nature. Cetyl alcohol is gentle on delicate skin and doesn't irritate it like other types of alcohol that can be drying or irritating, making it a suitable substance for sunblock.
Because it doesn't deplete the skin of its natural oils or make it dry, it's a recommended
component for those with reactive or sensitive skin. Thanks to its mildness, it may be used in a variety of skincare products, including ones meant for sensitive regions like the face and the area around the eyes -
Zinc Oxide
Another important ingredient in sunscreens is zinc oxide. Zinc oxide is renowned for its ability to offer
powerful sun protection. It acts as a physical sunscreen by sitting on top of the skin, reflecting and
dispersing UV rays, including UVA and UVB, to stop them from getting through. This broad-spectrum
protection is essential for lowering the risk of sunburn, skin cancer, and UV-induced premature aging.
Zinc oxide is essential in sunscreens as it is the best option for sensitive skin since it doesn't cause irritation
as chemical sunscreens can, and it provides instant protection from UV rays without absorbing them and
turning them into heat. It promotes skin regeneration and repair. It helps small burns, abrasions, and
wounds heal. Its antiseptic qualities aid in preventing infections, and its capacity to create a barrier of
defense promotes the skin's natural healing process. -
Carbopol
Most people are aware of carbopol's function as a thickening ingredient in skincare products. This polymer
aids in raising formulation viscosity, giving gels, creams, and lotions a desired texture and consistency.
Carbopol ensures that products are easy to apply and distribute evenly throughout the skin by forming a
smooth and stable gel matrix. This thickening quality improves the user experience overall, adding
pleasure and effectiveness to skincare regimes.
Apart from its thickening properties, carbopol serves as a stabilizing agent in skincare formulas. By keeping
the components of water and oil from separating, it aids in maintaining the homogeneity of the goods.
Through stabilization, the product's active chemicals are dispersed uniformly, preserving its efficacy
throughout time. Formulations that contain Carbopol have a longer shelf life and are thus more
dependable, making it a suitable ingredient for sunscreens.
Moreover, a lightweight feel in skin care products like sunscreens is also facilitated by carbopol. It aids in
the production of non-greasy and skin-absorbing products. For those with oily or mixed skin, this light
texture is especially helpful because it hydrates without leaving a thick or sticky residue. Carbopolcontaining products provide an enjoyable application experience.
Steps to Choose the Right Sunscreen
Here are some tips to help you find a suitable sunscreen for your skin.
-
Determine Your Skin Type
The type of sunscreen that is appropriate for you depends primarily on your skin. Choose a noncomedogenic sunscreen for skin that is oily or prone to acne, since it is unlikely to clog pores and result in
outbreaks. For these skin types, lightweight, gel- or water-based treatments work best. To help keep skin
hydrated, look for a sunscreen that has hydrating elements like glycerin or hyaluronic acid if you have dry
skin. Seek sunscreens that are hypoallergenic, devoid of harsh chemicals and odors, and limit skin irritation
if you have sensitive skin. -
Look for Required SPF Levels
When selecting a sunscreen, one of the most crucial things to take into account is the Sun Protection
Factor (SPF). Sunscreens with an SPF of at least 60 provide some protection from UVB radiation, which is
the main cause of sunburn. UVB rays are blocked by an SPF 30 of around 97% and by an SPF 50 of about
98%. Most people should apply sunscreen with an SPF of at least 30 every day, but those with fair skin
who burn easily or those who spend a lot of time in the sun may need to use one with a higher SPF.
Knowing SPF makes it easier to choose a product that provides sufficient protection for your individual
needs. -
Think about Physical or Chemical Sunscreens
Sunscreens come in two primary varieties: chemical and physical (mineral). Active mineral components
included in physical sunscreens, such as titanium dioxide or zinc oxide, lay on top of the skin and deflect
UV radiation. They are advised for youngsters, individuals with delicate skin, and those who are prone to
allergies because they are usually less irritating. In contrast, UV rays are absorbed by chemical sunscreens
and turned into heat. They are appropriate for daily usage since they are often more beautiful cosmetically
and simpler to apply without producing a white cast. When choosing between these sorts, take your skin's
tolerance and preference into account.
Common Myths and Facts About Sunscreen
Here are some myths about sunblock.
● Many people believe that wearing sunscreen will prevent you from absorbing essential vitamins like vitamin D. However, this is not true. While sunscreen block UV rays, it allows your body to take vitamin D.
● Another myth is that people with darker skin complexion don’t need sunscreen which is not true. Even though people with darker complexions are comparatively more protected from the sun, they must use sunscreen to avoid sunburn and medical problems like skin cancer.
● Many individuals also believe that if you are applying a high-level SPF like SPF 50, you don’t have to reapply it. However, this is a myth. No matter the SPF number, you must reapply sunscreen every 4-5 hours.
● One of the most common myths is that sunscreens don’t expire. Just like every other skincare product, sunscreens also have a shelf-life and expiry date after which you should not use it.
● People believe that sunscreens protect your body from tanning. While sunblock can protect against UV rays, it may not protect your body from tanning completely.
Here are some facts about sunscreen.
● Sunscreen allows you to decrease the chances of developing serious skin conditions like skin cancer. Remember, UV radiation can contribute to this medical condition. Not just that, UV radiation can also lead to other medical conditions like melanoma. Therefore, sunscreen is vital as it blocks the UV rays.
● One of the most important facts about sunscreen is that it can save you from excessive sun damage. It ensures that UV rays don’t enter the skin, reducing the chances of harming skin cells.
● Sunblock also protects you from sunburn. As you may already know, sunburn can boost the chances of developing serious medical conditions like skin cancer. Along with that, it can also worsen pre-existing skin damage over time. However, using sunscreen will ensure that you remain protected against sunburn.
● Another fact about sunscreens is that it can contribute to making your skin appear more even. It prevents overproduction of melanin, saving you from uneven skin tone and texture. It also stops pigmentation problems, improving your overall look.
Tips to Apply Sunscreen
● You must use a substantial amount of the product in order to attain the SPF rating stated on it. An adult should use roughly one ounce, or about a shot glass full, for their entire body. Use a dollop roughly the size of a nickel on the face and neck. Make careful to cover any exposed parts, such as the back of the hands, ears, feet, and neck.
● Apply the sunscreen for at least 15 to 30 minutes before going outside for the best results. This enables the substance to coat the skin in a barrier of defense. This permits the active chemicals in chemical sunscreens to properly bond to the skin.
● Reapplying sunscreen every two hours is recommended, or more regularly if you are perspiring, swimming, or toweling off. Even sunscreens that are water-resistant start to lose their potency after 40 to 80 minutes in the water. To make sure you can reapply as needed during the day, you should have sunscreen handy.
● To keep sunscreen useful, store it somewhere cool and dry. Heat can deteriorate the active components, so avoid putting them in heated places like a vehicle. Regularly check the expiration date and replace any sunscreen that has gone bad or has been incorrectly kept.
● A non-comedogenic, lightweight sunscreen is appropriate for everyday use, especially for the face. Use a stronger, more water-resistant product if you're going to be outside. Sticks and sprays make reapplication easier, especially when applying in difficult-to-reach places or when traveling.
● Ensure that you cover any exposed skin. This includes areas that are sometimes overlooked, such as the scalp if you have no hair or thinning hair, the back of the neck, the top of the feet, and the ears. Use an SPF-rated lip balm to provide your lips with the necessary protection.
