Chemical vs. Physical Sunscreen: Which Is Better for You?

In This Article

Wearing sunscreen daily is one of the most powerful acts of self-care you can give your skin. There are two kinds of sunscreen—chemical and physical—and understanding the difference can help you choose the formula that aligns with your skin’s unique needs.

So many of life's most treasured moments occur outside in the sun: picnics in the park, walks with friends, and exploring a new neighborhood or destination. But while soaking up the sunshine it's imperative to protect your skin with sunscreen, wearing it each and every day. Did you know there are two kinds of sunscreen; chemical sunscreen and physical sunscreen? Understanding the difference between the two iterations is fairly simple and can help you uncover your perfect SPF formula. Read on to discover everything you need to know about the two types of sun protection and the best option for your skin type.

What is Physical Sunscreen?

Physical sunscreen contains active mineral ingredients, like titanium dioxide or zinc oxide, making it a mineral sunscreen. A physical sunscreen works by sitting on top of your skin to form a shield and reflect against harmful and damaging UV rays.

What is Chemical Sunscreen?

Chemical sunscreen contains organic compounds, like oxybenzone, octinoxate, octisalate, and avobenzone. These compounds gently sink into the skin by absorbing UV rays and changing them into heat and then releasing that heat from the skin.

Physical Sunscreen vs. Chemical Sunscreen

Both sunscreens are wonderful and necessary – it just depends on your personal preference.

Pro: Physical Sunscreen is Non-Irritating

Physical sunscreen is a natural broad-spectrum sunscreen, as it offers sun protection from both UVA and UVB rays. It also protects your skin from the sun as soon as it’s applied – you do not need to wait for it to take effect.

Physical sunscreen is ideal for those with sensitive skin or acne-prone skin, as it is less likely to cause stinging and clog pores. Its shelf life is also longer than chemical options and it’s more photostable, so it doesn’t need to be reapplied as often as a chemical sunscreen.

Con: Physical Sunscreen White Cast

It is important to note that physical sunscreen can sweat, rinse, or rub off more easily. For full protection, you need to apply a generous amount and ensure it is rubbed completely into the skin.

Physical sunscreen can also leave a whitish cast if the formula has a high zinc percentage. Zinc oxide is wonderfully anti-inflammatory and particularly great for sensitive and reactive skin – but it can give a sunscreen a thicker consistency and white cast. (Although newer innovations, especially Japanese sunscreens, are formulated so as to not cause either a white cast or greasy feel, so don’t count it out!)

Pro: Chemical Sunscreen Applies Easily

Chemical sunscreen tends to be thinner and spread more easily and flawlessly on the skin, so it can be more suitable to wear under makeup. They often don’t rely on zinc formulas, so they won’t commonly have a white tone, making them ideal for darker skin tones. Also, the formula often includes ingredients that treat and protect the skin, like peptides, antioxidants, and enzymes. Making them a one-two punch of skincare and sun protection.

Con: Chemical Sunscreen Can Be Irritating

Multiple active ingredients are combined to achieve UVA and UVB chemical protection, so there may be a higher chance of stinging and irritation for some, especially dry skin – and this potential irritation increases as the Sun Protection Factor increases, especially for sunscreens with SPF 50 or more.

Additionally, chemical sunscreens need at least 10 to 15 minutes after application to achieve full protection. And it’s ideal to reapply frequently, as protection dwindles under direct UV light.

Prone to dark spots? It’s highly unusual, but some dark-spot-prone chemical sunscreen users can see an increase in existing dark spots and discoloration. This is because of the chemical reaction when using chemical sunscreens that increases your internal skin temperature slightly. And one of the two main causes of melasma is heat. It should be noted that this interaction is very rare, and almost all SPF coverage helps prevent dark spots – not cause them.

Speaking of reactions, some chemical sunscreens can cause clogged pores for acne-prone users, causing blemishes. This can occur when the oils or comedogenic ingredients used in some formulas irritate the skin, causing an adverse reaction. But this can also occur in physical sunscreens. To avoid any irritation, look for products that note they’re non-comedogenic.

Dual Chemical AND Physical Sunscreen

For the best of both worlds, some SPFs combine both chemical and physical sunscreen in one product. The formula can take away the woes associated with each type of protection, allowing greater ease of application, longer-lasting wear, and stronger coverage.

Which is Best for You?

The most important thing is to wear sunscreen daily. There is no superior SPF protection – whatever option you’ll use daily is the best sunscreen for you. There are many outdated and negative associations with sunscreen, like stinky, thick, or sticky formulas. But it’s an exciting, innovative time in skincare: modern sunscreens – whether they are chemical, physical, or a blend of both – are wonderfully advanced and not only protective, but oftentimes have cosmetic benefits that improve the skin’s overall health. Still can’t decide which is right for you? There are a few things to consider that’ll help you narrow down your search.

Consider Your Skin Type

Note your skin type – certain skin might enjoy using a physical sunscreen over chemical, or vice versa. Have reactive or sensitive skin? Tend to breakout a few times a week or month? A physical sunscreen (or a non-comedogenic chemical) is probably best for you. More oily skin? Or resilient, non-reactive skin? A chemical sunscreen might work beautifully for you. (That said, again, whatever sunscreen you enjoy using is the best sunscreen for your skin.)

Consider Your Skin Tone

Those with deeper skin tones can find physical sunscreens difficult to apply without leaving a frustratingly ghostly cast behind. Chemical protection can provide a more seamless, invisible application. But don’t count physical out entirely: there is a new genre of tinted physical sunscreens that might work perfectly for medium to dark tones.

The Best Physical & Chemical Sunscreens

At Tatcha, we take the honor of caring for your skin very seriously, especially when it comes to something as important as sunscreen. We recommend choosing a broad-spectrum sunscreen with at least SPF 35 protection. Here are a few of our favorite formulas.

Dual Chemical & Mineral Sunscreen

Consider our Silken Pore Perfecting Sunscreen, which is a weightless sunscreen with broad-spectrum protection (meaning it provides coverage from both UVA and UVB rays). The SPF 35 blends effortlessly and invisibly for refined pores and a matte finish. It features both chemical and mineral SPF, allowing for a nearly invisible finish, while also providing lasting protection against the sun.

Hate thick sunscreens? You’ll love this weightless option then, the lightweight protection is formulated with silk extract for a silky-smooth feel, and Japanese wild rose to help tighten the look of pores and smooth skin texture. Meanwhile, loquat leaf extract offers a rich source of antioxidants to protect and calm your skin.

Archaic sunscreen used to sit uncomfortably under the skin, but Silken Pore Perfecting Sunscreen is perfect as a primer for your makeup, without leaving a chalky finish. Our sunscreen is non-comedogenic, dermatologist-tested, and cruelty-free, and is formulated without parabens, synthetic fragrances, mineral oil, sulfate detergents, phthalates, DEA, or TEA.

Mineral Sunscreen

Looking for a silky, lightweight, invisible sunscreen with 50+ mineral coverage? Allow us to proudly introduce our newest innovation – The Silk Sunscreen.

For the base of our brand-new sunscreen, we turned to a timeless ingredient used in beauty rituals for nearly two thousand years – silk. Silk features an amino acid structure similar to that of skin, which allows the silky liquid to provide a protective veil of hydration without weighing your skin down.

Not only does the new Silk Sunscreen feel impossibly light, but the invisible protection also impressively minimizes pollutant and allergen disruption. In addition to silk extracts, niacinamide visibly evens skin tone, reduces redness, and visibly firms the look of pores. And hyaluronic acid helps to immediately boost skin’s natural moisture levels, softness, and skin tone. Basically, it makes your skin feel healthier, while also providing incredible sun protection.

Most importantly though, the sheer liquid provides 50 broad-spectrum protection against UVA and UVB rays, with 10 percent zinc oxide for a mineral, reef-safe filter.

Can’t decide between Silk Sunscreen and Silken Pore Perfecting Sunscreen? If you’re looking for higher sunscreen protection with a more milky, liquid format, Silk Sunscreen is perfect for you. If you prefer a cream, with both mineral and chemical protection, our bestselling Silken Pore Perfecting SPF 35 Sunscreen is a superb option.

No matter what broad-spectrum sunscreen protection you choose though, the most important thing is to apply it daily. Basking in the sun is one of life’s simple pleasures – but only if you have SPF coverage on to enjoy it.

The Best Foaming Facial Cleanser

Foaming cleansers can be effective for all, but the secret to using them correctly is discovering a formula that is ideal for your skin type. A creamy foaming cleanser, which imparts a soft hydration onto the skin as cleansing, is more ideal for dry skin, while a refreshing foaming cleanser that includes oil-balancing ingredients is more ideal for combination and oily skin tones. Some formulas work by allowing the dense bubbles to grasp onto debris, sebum, and makeup, washing away in a single step. While other formulas might need an oil cleanser first to break down these trickier long-lasting ingredients.

The Best Blemish Begone Skincare Products

Blemishes can be caused by a variety of things, and are a fact of life. But choosing the right skincare products can help you keep breakouts at arm’s length. Blemishes happen to all of us. But to some of us, they happen more often than not. We call ourselves blemish-prone. And in addition to our usual skincare routines for morning and night, we make active choices about the products we use to make sure blemishes stay away. The word blemish, from the French blessmiss—to make angry—might be the most polite way to refer to many types of skin blemishes like acne, pimples, zits, and all of the other names we ascribe to those skin reactions that cause small unusual bumps. A bit ironique, considering that the word we now associate with acne connotes an imperfection or something else wrong. And while acne can be caused by imbalances in the skin, it’s common enough for all of us not to make it such a big deal. These are not mountains. They’re even much smaller than molehills. Still, those who deal with blemish- or acne-prone skin know that not all skincare products are created for the same skin type. All of us need to choose the right cleanser and moisturizer for our skin, but how we do so is up to us—and, usually, to the specifics of our skin’s behavior. A dermatologist should be your first stop on your skincare journey, but the following guide can help shed a little light on the acne-prone skin type, and some of the common skincare choices (and the optimal acne skincare routine!) made by those who have it. What is blemish-prone skin? Blemish-prone skin is another term for oily skin, which is one of the major skin types. Oily skin is usually categorized by skin that produces more sebum than so-called “normal” skin, but there are a few ways to glean more information about how your skin behaves at baseline. “Oil” is a poetic name for sebum, the waxy substance made of lipids like cholesterol, squalane, and glycerides that is secreted from sebaceous glands that sit within pores and hair follicles. Sebaceous glands are an important mechanism that our skin uses to moisturize and protect itself. Many of our sebaceous glands can be found on our faces and scalps, though there are a few places we don’t have sebaceous glands—like on our lips, or the bottoms of our feet. Sebum is a protective substance that helps to seal moisture by shoring up our skin barrier. In other words, it’s a good thing to have. But those with oily skin can have too much of it, and too much can lead to a higher incidence of breakouts. While oily skin can be a genetic trait, it can also be influenced by the environment around us—the climate, for instance—and our own behaviors—like how we take care of our skin. How do blemishes occur? You’re unlikely to find the term “blemish” in dermatology coursework. Generally, when we’re talking about a blemish, we’re talking about a form of acne, which is described most concisely as a blocked hair follicle. The pores that dot our skin are small channels that house sebaceous glands and hair follicles; they help traffic sebum up and out of skin. When sebum and dead skin clogs a pore, it may become what is called “common acne”, though there are a few types. Blackheads and whiteheads are caused by sebum buildup, and are distinguished by whether or not they’re open (and black) or closed (and white). When an infectious bacteria is introduced, it can cause a more robust infection, resulting in other forms of acne like papules and pustules that are painful to the touch. If you need help identifying what kind of blemish has popped up on you, head to your nearest dermatologist’s office to find out. What are the most important blemish skincare steps? Perhaps the most important thing to do in the face of acne is: Not panic! Breakouts happen to all of us, and usually fix themselves on their own. But if you identify with the oily skin type, and find yourself devoting more time to quelling breakouts than you’d like, you might want to consider some of the skincare products for oily skin, which are popular among those with acne-prone skin. A few common switches include: Cleansing with a gel. Dermatologists at the University of Florida Health once proclaimed that “the most important thing you can do for oily skin is to keep your skin clean.” Those with oily skin may want a cleansing formula with more reach than surface-level face washes—something that can cleanse pores deeply, ensuring they remain clear of acne-causing buildup. Gel cleansers are usually the ones for the job. Water-based gel cleansers are slippery, clear, and tend to foam up. Tatcha’s brand new Matcha Cleanse is a soapless gel that deeply decongests pores— thanks to a unique gel-to-foam texture—to reduce oil, and visibly calm skin without stripping. The Matcha Foam Cleanser takes on oiliness with a gentle touch: balancing the microbiome, soothing, and calming. Exfoliating with acids. There’s a reason that the inventors of alpha hydroxy acids have been honored all over the world. Their contribution to skincare includes one of the most popular exfoliating acids of all time—and it’s a boon for those with oily skin. AHAs, as they’re known, help to “peel” the skin by breaking down the bonds between old and new skin cells. Exfoliation is essential for all skin types, but the ease of AHAs and their efficacy in removing dead skin makes them great for oily skin. They’re commonly recommended to those with oily and acne-prone skin, especially in the form of a daily treatment. A product like the Texture Tonic, which takes the form of a lightweight daily toner, allows you to fit gentle exfoliation into your regular skincare routine—right between cleansing and moisturizing. Its AHAs come from a cornucopia of fruit sources proven to resurface uneven and dull skin—leaving it smooth and radiant. Moisturizing with water Sure, the idea of moisturizing with nothing but water may sound counterintuitive, or downright impossible. And yet it's the animating idea behind the Water Cream, Tatcha’s best-selling moisturizer for oily skin. This lightweight, oil-free cream has a bursting effect when applied, flooding the skin with vital and necessary hydration. It’s also beloved for its powerful superplant ingredients that address traits commonly found in oily skin, like antioxidant-rich wild rose (which has the benefit of smoothing the appearance of large pores) and anti-inflammatory heartleaf extract (a natural azelaic acid alternative). Masking with clay When it comes to natural ingredients that help oily skin, you can’t beat clay. Clay helps absorb excess oil, and is said to also draw impurities out of the skin. Anyone who has used a clay mask can attest to its drying powers, which is why it’s not usually a daily ingredient. Instead, it's suited for more irregular use, like in a face mask. The Clarifying Clay Mask, formulated as a treatment for oily skin, uses marine mineral-rich kucha clay sourced from the islands of Okinawa. For centuries prior, Okinawan women have cherished kucha clay for its superb oil-absorbing properties, using it as a hair powder or face mask. When mixed with volcanic ash and exfoliating Japanese konjac, it makes for smoother, clearer skin in no more than three minutes. 180 seconds per week may not alone calm oily or blemish-prone skin, but good holistic skincare habits will.
