What Is Sun Protection
Sun protection involves shielding the skin from the damaging effects of solar ultraviolet (UV) radiation. Visible light is seldom a problem except in some specific photosensitivity disorders such as porphyrias. Exposure to UVA and UVB radiation contributes to skin ageing and is the main cause of skin cancer (eg, basal cell carcinoma, squamous cell carcinoma, and melanoma). UVB is also the main cause of skin reddening and sunburn through damage to the upper epidermal layers of the skin. Sun protection methods, including sunscreen and sun protective clothing, are important in reducing these damaging effects.
Advantages of Sun Protection
They provide fantastic protection
The minerals in physical sunscreen block out UVA and UVB rays, making them very effective at protecting the skin from cancer-causing radiation.
They work immediately upon application
Because they provide a physical barrier against the sun, physical sunscreens will be effective from the moment they are applied.
Great for sensitive skin
Physical sunscreen is not absorbed by the body, making it much less likely to irritate the skin, clog pores, or cause redness.

Sun Protection Ingredients for UV Protection
Niacinamide
Niacinamide, or nicotinamide, is a water-soluble topical version of vitamin B3. An essential nutrient for the body, it helps to develop proteins in the skin and locks in moisture. Along with good skin health, niacinamide protects the skin from sun damage. The active ingredient works in formulas to repair and restore healthy skin cells while simultaneously protecting the cells from UV damage.
Hyaluronic Acid
Hyaluronic acid (HA) is produced naturally in the body as a clear, gooey substance. The naturally-occurring glycosaminoglycan is formed from long, unbranched carbohydrates, or a group of sugar molecules, called polysaccharides.HA provides hydration and enables the body to retain moisture—one of its star qualities. The sun often causes skin to become dry and leathery; this is where sunscreen formulations with HA come in as they moisturize the skin (especially its top layer) when it doesn’t have enough water. The ingredient’s role is to support and lubricate the body and is produced in the body’s skin, eyes, and connective tissues.
Butyl Methoxydibenzoylmethane (BMBM)
Butyl Methoxydibenzoylmethane, or BMBM, is a synthetic, oil-soluble sunscreen used to protect the skin from the sun. The ingredient is known for being a sun filter and is formulated for the skin, scalp, and hair. It provides a defense against sun exposure by preventing the absorption of UVA or UVB rays. As the ingredient is hydrophobic (repels or fails to mix in water) and is oil-soluble, BMBM is applicable in water-repellent and water-resistant formulations. Approved for 3% use in formulations in the US and 5% in Europe at present, BMBM provides numerous benefits, including its ability to absorb UV light over various wavelengths and transform it into less damaging infrared radiation (heat). In addition, BMBM in product formulations also prevents natural and synthetic hair dyes from fading in the sun and improves chemical hair color stability.
Octocrylene
Octocrylene is a chemical sunscreen ingredient typically found in UV protection skincare products. A chemical sunscreen ingredient is one that works by protecting the skin against sun damage once it’s absorbed into the skin. The ingredient protects the skin from both UVA and UVB rays and helps stabilize and improve the efficacy of other chemical sunscreen ingredients in formulations—making it a popular and frequent choice for UV protection sunscreens. Octocrylene is also known to increase the water-resistance of sunscreen and helps protect the skin from sunspots and skin aging.
Titanium Dioxide
Titanium dioxide, a popular ingredient in physical sunscreens, is a broad-spectrum filter, which means it provides proportional UVA and UVB protection. However, it’s not able to protect the skin from long UVA1 rays, which refers to UV light in the range of 340–400 nanometers (nm). Titanium dioxide is used in many SPF-specific applications, including makeup, pressed powders, and lotions. Physical formulas rely on minerals such as titanium dioxide and are designed to sit on the skin and deflect the sun’s rays to protect the skin from damage.
Zinc Oxide
Zinc oxide is a mineral-based active ingredient used in sunscreens. Physical UV protection sunscreens require minerals such as zinc oxide and protect the skin by scattering the sun’s rays, preventing potentially harmful UV rays from reaching the skin. Available for physical sunscreen formulations, zinc oxide is deemed an effective, relevant, and photostable sunscreen choice for sensitive skin users. Zinc oxide can also effectively work as a barrier against the sun for babies and young children whose skin is not as developed and mature as adults’ skin.
Ceramides
Ceramides are a class of long-chain fatty acids called lipids. These are naturally found in skin cells and make up around 50% of the outer layer of skin, called the epidermis. These acids connect with other molecules in the skin to encourage cellular function and produce a barrier to avoid permeability. The act of shielding the skin helps keep its moisture, preventing dryness and irritation. A recent study explored the benefits of using ceramide. Its researchers explored the impact of UV exposure on the skin and strived to understand the protective efficacy of a sunscreen containing ceramide and moisturizing cream. They found that creating a skincare regimen that includes a moisturizer and sunscreen formulated with ceramides can help protect against UV-induced skin barrier damage and improve overall skin barrier health against chronic sun exposure.
Basic Knowledge About Sun Protection Ingredients
SPF 30 means it would take 30 times as long for you to get a sunburn, compared to not wearing sunscreen. Say you burn after one minute of exposure. If you were to wear an SPF 30 sunscreen, it would take you 30 minutes to burn. Anything greater than SPF 50 has nearly the same benefit as SPF 50. SPF 30 blocks 97% of harmful rays and SPF 50 blocks 99%. It’s important to reapply your sunscreen as directed to keep that protection, which is typically every two hours.
Ultraviolet radiation, or UV, is present in sunlight. This type of sun ray can mutate the DNA in skin cells causing skin damage and skin cancer. About 95% of the UV radiation that reaches the earth’s surface is UVA while UVB accounts for the other 5%.
UVA plays a minor role in sunburn and skin cancer, but it contributes most heavily to photoaging like brown spots and wrinkles. UVB plays a major role in both sunburn and skin cancer, so it’s important to protect against this harmful ray.
Mineral sunscreens are made of such ingredients as zinc oxide and titanium dioxide. They are also called physical sunscreens because the ingredients physically act as a barrier between skin and the sun’s rays. These sunscreens work by blocking and scattering both UV and visible light, so they are less irritating to the skin, and they are immediately effective when applied. The drawback is that some formulations leave a white appearance when applied to the skin that some people might not like. Chemical sunscreens have ingredients like benzophenone, avobenzone, oxybenzone, and para-aminobenzoic acid (PABA).
These actually absorb light and then reemit it as energy, like heat. Chemical sunscreens need to sit on your skin for about 15 minutes before they take effect. They give less of a white appearance to the skin than mineral sunscreens.When it comes to sunscreen application, recommends selecting a lotion over a spray. I much prefer a lotion or cream because you are directly applying it to your skin, whereas when you apply sunscreen spray outdoors, a lot of it is just carried away in the wind.
How Does Sun Protection Ingredient Work
Sun protection ingredients prevent uv rays from damaging your skin. There are two categories of sun protection ingredients.
Physical blockers
Physical blockers contain minerals such as titanium dioxide or zinc oxide ground into fine particles. These minerals sit on the surface of the skin and reflect uv rays away from your skin a lot like a shield or mirror would. Sunscreen products that contain physical blockers are sometimes called sunblock or mineral sunscreens.
Chemical absorbers
Chemical sun protection ingredients form a thin protective film that absorbs uv radiation before it penetrates the skin. Sunscreen products that contain chemical absorbers are sometimes called organic sunscreens.
Both types of sun protection ingredients have pros and cons.
For example, physical blocker sunscreens generally do not cause irritation, stinging or allergic reactions, but they can be white and greasy. Meanwhile, chemical absorber sun protection ingredients are usually clear and easy to apply, but these are more likely to cause irritation and allergic reactions.
Many sunscreens use a combination of physical blockers and chemical absorbers to maximize the benefits and reduce the downsides. Additionally, many broad-spectrum sunscreens need a combination of ingredients to protect against uva and uvb rays, the two types of ultraviolet rays that cause skin damage.
These five tips from board-certified dermatologists tell you which type of sunscreen to use, how to apply it correctly, and when to reapply: Choose a sunscreen that has an SPF of 30 or higher, is water resistant, and provides broad-spectrum (UVA and UVB rays) coverage. When this sunscreen is also a tinted sunscreen with iron oxide, you better protect your skin from developing dark spots. Iron oxide protects your skin from the sun’s visible light.
Apply sunscreen before going outdoors
It takes approximately 15 minutes for your skin to absorb the sunscreen and protect you. If you wait until you are in the sun to apply sunscreen, your skin is unprotected and can burn.
Use enough sunscreen
Most adults need about 1 ounce — or enough to fill a shot glass — to fully cover their body. Rub the sunscreen thoroughly into your skin.
Apply sunscreen to all skin not covered by clothing. Remember your neck, face, ears, tops of your feet, and legs. For hard‐to‐reach areas like your back, ask someone to help you or use a spray sunscreen. If you have thinning hair, either apply sunscreen to your scalp or wear a wide‐brimmed hat. To protect your lips, apply a lip balm with an SPF of at least 30.
To remain protected when outdoors, reapply sunscreen every two hours, and immediately after swimming or sweating. People who get sunburned usually didn't reapply, used too little sunscreen, or used an expired sunscreen.
Your skin is exposed to the sun's harmful UV rays every time you go outside, even on cloudy days and in the winter. So whether you are on vacation or taking a brisk walk in your neighborhood, remember to use sunscreen.
What to Look for When Buying Sun Protection Ingredient
Choosing the right sunscreen isn’t always as easy as grabbing the first SPF you see on the skincare aisle. For starters, you’ll want to make sure your sunscreen-of-choice can protect your skin from both UVA and UVB rays while also being able to withstand sweat and water exposure. Below is a list of essential sunscreen considerations as recommended by the American Academy of Dermatology (AAD) and skincare experts.
The Right SPF
Sun protection factor or SPF refers to your sunscreen’s ability to protect your skin against UVB rays, so it’s commonly assumed that higher SPFs equal stronger protection. You should choose at least an SPF 30 sunscreen for daily use as it can filter up to 96.7 percent of UVB rays. But if you are fair-skinned, engage in outdoor activities, or have a higher risk for skin cancer, an SPF 50 sunscreen is your best bet. It can shield your skin from 98 percent of UVB rays and provide some room for error in case of under-application.
Broad-Spectrum
SPF values only indicate your sunscreen's coverage against UVB rays, which is why it’s important to make sure your sunscreen is also labeled as broad spectrum. A broad spectrum sunscreen means it offers protection from both UVB and UVA rays, which have longer wavelengths and can penetrate deeper into the skin.
Sunscreen Formulation
These days, sun protection comes in all shapes, sizes, and formulations—from lotions and creams to gels, sprays, and even powder. Ultimately, choosing the right formulation boils down to your personal preference and skin type, especially since sunscreen isn’t an apply-and-forget type of deal. You’ll want to pick a sunscreen that’s convenient for you to apply, reapply, and carry around throughout the day.
Additionally, consider your skin type. If you have dry skin, opt for creams and lotions to help your skin stay moisturized. Lightweight gels or powders with a matte finish are good for oily skin to help keep shine under control. Meanwhile, mineral, non-comedogenic, and hypoallergenic formulas are recommended for sensitive and acne-prone skin.
Water Resistance
No sunscreen is truly waterproof, but they can be water-resistant. Experts recommend opting for water-resistant sunscreens, especially if you’re swimming or sweating excessively from exercise or sports. According to the AAD, sunscreens can only be water-resistant for either 40 or 80 minutes, so make sure to reapply them consistently afterward.
Chemical vs Mineral Sunscreens
Sunscreens fall under two different types, chemical and mineral, and their main difference lies in their active ingredients. Chemical sunscreens, as the term implies, rely on a cocktail of chemical ingredients that work hand-in-hand to protect the skin from UVA and UVB rays. They absorb and degrade UV light and create a chemical reaction that turns them into heat before releasing it from the body.
Meanwhile, mineral or physical sunscreens harness the natural UV filtering properties of titanium dioxide and zinc oxide. These mineral blockers form a layer of protection on the skin that filters and deflect UV rays away from the body, much like a mirror that reflect light.
While both types of sunscreens are effective against UV radiation, most experts prefer mineral sunscreens over chemical ones because they are photostable, have a natural and broader UVA and UVB coverage, and work as soon as they are applied.
Your Level of Sun Exposure
Your level of sun exposure varies depending on your activities, the time of day, geographical location, and the UV index. If you frequently engage in outdoor activities for hours at a time or live in an area close to the equator, it’s best to choose an SPF 50 sunscreen to compensate for your level of sun exposure and adjust the frequency of reapplication.
