Have you ever found yourself in front of the sunscreen display only to come down with a severe case of option exhaustion. What's the right SPF? Water-Resistant or Not? What the heck is broad-spectrum? What is mineral sunscreen and why is everyone telling me to use it?


So, leaving your research for another day, you grab what's on sale, or the same old bottle you've been using since childhood.


There's been a lot of chitter chatter about sunscreen over the last few years, particularly around ingredients, efficacy, and what's considered safe for our bodies, the reefs and the planet. We often get asked about the difference between mineral and chemical based sunscreens so let us break it down for you:


Mineral-Based Sunscreen (may also be referred to as a physical sunscreen):

A mineral or physical sunscreen is a formulation of physical UV filters, primarily zinc oxide or titanium dioxide that provides broad-spectrum UV protection by physically reflecting UV rays from the skin (Adamson & Shinkai, 2020). In essence, they are blocking the sun's UV radiation by providing a physical barrier.


Since they work by creating a physical barrier, mineral sunscreens start protecting you as soo as they're applied to the skin.


Chemical-Based Sunscreen:

Chemical-based sunscreens make up the majority of sunscreens on the market and are the sunscreens most commonly found at your local drugstore. Chemical sunscreens contain UV filters that absorb UV radiation (Adamson & Shinkai, 2020). Instead of sitting on top of the skin, the UV filtering chemicals in these sunscreens penetrate the skin and protect you from UV radiation without forming a visible layer on the skin . The most common active ingredients in chemical sunscreens are: oxybenzone, octinoxate, homosalate, octisalate, octocrylene, and avobenzone (EWG, 2017).


Since they need time to absorb, chemical sunscreens need to be applied about 15-20 minutes before sun exposure.



How to choose:

Both mineral and chemical sunscreens can offer the same broad-spectrum UVA/UVB protection. Of course, this can vary from brand to brand so it's important to do your own research. If protection quality is similar, some other influential factors when choosing between the two include:


Appearance / Texture:

Mineral sunscreen is traditionally thicker, creamier and can leave a white cast on the skin (think retro sunscreen ads with white, pasty noses.) If the appearance of sunscreen on the skin is a concern, you may opt for a chemical sunscreen that leaves no trace on the skin, or a tinted mineral one, or some of the newer mineral formulations that are marketed as having 'no white-cast'.


Ingredients:

Mineral sunscreens made with zinc oxide and titanium dioxide are classified as safe ingredients and research shows that few, if any, zinc or titanium particles penetrate the skin. The ingredients in chemical sunscreen on the other hand are associated with a number of health concerns including allergies and hormone disruptions (EWG, 2025).


If you're concerned about the ingredients in your sunscreen, a great place to start is the Environmental Working Group's 'Skin Deep' Database. This comprehensive database provides consumers with full reports on personal care items, ingredients, toxicity ratings, and a list of 'EWG Verified' products. The EWG verification means a product has met the strictest standards for health and safety and contains none of the EWG's identified chemicals of concern. Many mineral-based sunscreens are EWG verified, particularly if they do not contain synthetic fragrance. If choosing a chemical sunscreen, look for low-hazard ratings.


Environmental Impact:

If you've been on a snorkeling trip recently, your guides have likely required that all snorkelers use reef-friendly sunscreen. This is due to the adverse impacts of sunscreen on aquatic life, including the damage to coral reefs as well as reproductive, developmental and endocrine effects on marine organisms (Lebaron, 2022). For this reason, only sunscreens with zinc oxide or titanium dioxide are considered reef-safe.


Bonus - some manufacturers of mineral / reef-friendly sunscreen are values-based companies that truly care about the environment so they often employ other eco-friendly practices in their manufacturing process (like plastic-free packaging!)



Whichever your choice, you'll find a well-curated and intentional collection of both chemical and mineral based sunscreen at the Apothecary featuring brands like Sun Bum, Ombrelle, Attitude (Sunly + Oceanly), Green Beaver, and The Sunscreen Company.


My Favourites:

Personally, I've been a fan and a user of mineral-based sunscreen for over a decade. For me, it's the balance of protecting myself from the sun, while still being mindful of the ingredients I'm exposing my body to. If you're in need of a recommendation - here are my faves.


  • Favorite All-Over Sunscreen: Plastic-free Mineral Sunscreen Stick Spf 30 - EWG Verified & sold here at Teasdale Apothecary Co.

    • The stick application makes this SO easy to use and the butter base makes my skin feel nourished and hydrated. Simply rub on, and blend! (Bonus - great for travel as it's a solid, so it can go right in my carry-on without compromising limited liquid allowances!)


  • Favorite Daily Facial Sunscreen: Solid Tinted Oil Spf 30 with Zinc Oxide & Ave Isa Sun-e-Serum Drops SPF 35 Sunscreen - both EWG verified and sold here at the Apothecary.

    • Admittedly, I'm late to the game of ensuring my face is protected by an SPF everyday (I'm sorry to all of my estheticians who warned me about this 15+ years ago). When I finally listened at 37, I found myself struggling to find something that I felt comfortable incorporating into my daily routine. Alas, I found these two and brought them into the Apothecary. Most days I don't wear foundation, so that's when I reach for the tinted oil stick. Super easy to apply and it blends beautifully (if your skin is on the oilier side, it's available as a cream stick). I also want to try their shimmer cream stick! If I'm wearing foundation, I simply apply the serum drops before my foundation. It's silky-smooth, absorbs quickly and non-greasy.

Have you ever picked up a bottle of your favourite cleaner and had a ping of curiosity as to what it is, exactly? You read the ingredients only to be faced with a mountain of words you can’t pronounce. Sometimes it seems like ingredient lists can be as long as your arm - for everything from food to household cleaners and beauty products.


You would think that since we use these products on a regular basis, companies would make quality and safe ingredients their top priority, right? Wrong. Unfortunately for most commercial products, this isn’t high on the priority list. Many common household cleaners contain irritants to the skin, eyes, and lungs. There is also growing research around the link between asthma and prolonged exposure to common cleaning products. There are even products on the market that contain traces of cancer-causing chemicals like formaldehyde…yikes.[1]


Thankfully, there are many options (and perks!) in the world of green cleaning and we’ll be talking about this often on the blog. To start, we’ll introduce you to a few of our favourite tips and how you can start to think about ways in which you’d like to introduce more natural products to your home.



Get back to basics: A prime perk of switching to a natural cleaning routine is that many key ingredients can already be found in your kitchen or pantry – like vinegar and baking soda. A vinegar spray is as easy and cheap as it gets. Add equal parts water to equal parts vinegar to a spray bottle and you’ve got a simple and effective household cleaner. Don’t’ want your house smelling like a pickle? Add essential oils or infuse the vinegar with orange peels, lemon peels, or pine needles.


Wash it out: Have you ever wondered how the clothes you stuck at the back of the closet 6 months ago are still smelling like a fresh rose garden? You probably have your detergent or fabric softener to credit for that. A large portion of laundry detergents on the market contain a number of different chemical compounds that are harmful for the body and the environment. From the artificial fragrance to the surfactants used to clean the fabric, many of the ingredients are not ones that we want touching our skin daily.


A homemade laundry detergent can be a cheap, easy, and healthy alternative to the common liquid detergents sold at the store. One basic recipe from Mommypotamus contains:

  • 6 cups of washing soda (different than baking soda) (can also use 3 cups washing soda / 3 cups baking soda)

  • 3 bars of 4.5-5oz soap, finely grated with a cheese grater (Tallow soap flakes are recommended as but Kirk’s or Dr. Bronner’s castile soap work as well)

  • 100-150 drops of essential oil

  • Combine ingredients in a food processer and blend until a nice powder is formed. This recipe is suitable for top loader and HE washers, with about 3 tablespoons needed for a top loader and half that amount for a HE washer.

If you’re short on time or not into DIY, the Apothecary offers an excellent liquid laundry soap in bulk! It comes from 'Down East Cleaning Products' out of Dartmouth, Nova Scotia and is non-toxic and hypoallergenic. Swing by with your old laundry soap jug (or pick-up up a container from our donation table) and one of our staff can help with whatever you need and answer any questions you may have.


[Apothecary tip: If you can’t find a cleaner that’s scented with natural oils, buy an unscented version – that way if you must add scent, you can add your own essential oils.]


Breathe in the good stuff:

Another common product that has the potential to cause respiratory and health issues over time is air-freshener – running the gamut of plug-ins, aerosol sprays, you name it. For cleaning manufactures, many ingredients are not required to be displayed on the label. Since fragrance is considered a “trade secret”, we really have no idea what goes into scent profiles. Air fresheners have been found to contain many VOC’s (Volatile Organic Compounds) like formaldehyde, benzene, and toluene, just to name a few.[2] Lucky for us, there are lots of ways to keep our home smelling fresh without polluting our indoor air.

  • Use essential oils: essential oils are probably the most widely used, natural air-freshener. There are many ways to utilize the power of essential oils; by adding some to an electric or clay diffuser, wax candle warmer with water, or a clothes pin attached to a vent. The options are endless when it comes to essential oils; come check out our selection of pure and essential oil blends for every preference.*

  • Make a room spray: here’s an easy & quick recipe from The Organically Clean Home for a lemon-y fresh room spray:

- 1 cup distilled water; ½ cup vodka; 10-20 drops of lemon essential oil.

- Add ingredients to a spray bottle and shake to combine. Spray as needed. (Variation, substitute lemon with a combination of lavender and peppermint!

  • Pick something up at the Apothecary: If you’re looking for a ready-make product, we have an in-house room spray that is formulated with your health in mind. Made with a base of distilled water, witch hazel and sea salt, it boasts a fresh scent of eucalyptus and peppermint. Time to ditch artificial fragrance for good!


When we clean our homes, it gives us a sense of accomplishment and creates a warm and welcoming space for everyone who passes though the front door. While intentions are always good, the products we use may impact our overall health without us even knowing it. Taking the time to educate ourselves on harmful ingredients lurking in our products and healthier alternatives is something that your household, and future self, will thank you for.


Keep following along, as we share product recommendations, DIY recipes, and swaps for keeping your home clean, safe and cozy.
