Natural Beauty



Thanks to social media, we are bombarded with constant ‘noise’ about how to be healthy. It’s becoming more and more difficult to decipher what is true and who to trust to guide you on your personal health journey. We've created this Replete Wellness online journal as your doctor-approved, trusted source for online health content.


The Replete Guide to Non-Toxic Personal Care Products

We totally get it, the ‘clean’ make up & skin care world can be absolutely overwhelming. That’s why we are all about educating our patients on the worst offenders to look out for in their beautiful products while encouraging these replete beauties to make small changes to their daily beauty routines.

Ingredients found in your skincare products have sadly been shown to cause endocrine disrupting effects, including thyroid disturbance, cancer and hormonal issues. While most of these ingredients have some research showing possible safety when used in small quantities no one has ever done a study on the cumulative effects of all of these chemicals when applied daily. It’s not one product or one chemical that’s worrisome, it’s the accumulation of a number of products, and the reapplication of those beauty products every single day for years. On average, Canadian women use 9 personal care products daily, which exposes us to hundreds of unique chemicals, most of which haven’t been accurately safety tested.

While The following chemicals are the worst offenders and should be avoided when possible:

Petroleum jelly:

  • What is it? It’s mixture of mineral oils and waxes that results as a by-product of crude oil extraction.
  • Where to find it: Petrolatum is in one out of every 14 cosmetic products on the market, including 15 percent of lipsticks and 40 percent of baby lotions and oils.
  • Why it’s a problem: There’s a high risk of contamination from polycyclic aromatic hydrocarbons (PAHs); cancer-causing chemicals found in crude oil and its by-products.
  • Aliases: petrolatum, white petroleum, and soft paraffin


  • What is it? A colorless poisonous gas synthesized by the oxidation of methanol and used as a preservative.
  • Where to find it: Formaldehyde-releasing agents are used as preservatives in a wide range of cosmetics and most nail polishes and nail-hardeners contain residual formaldehyde concentrations up to 0.5 per cent.
  • What it’s a problem: Formaldehyde is well-document human carcinogen.  Though presently banned in the EU, Health Canada considers formaldehyde to be safe when used in small concentrations on the skin. Their claim is that it is such a small amount it cannot be harmful, however repeated, long-term exposure is shown to be associated with poor overall health outcomes.
  • Aliases: Diazolidinyl urea, 3-diol Imidazolidinyl urea, DMDM Hydantoin, Quaternium-15, Nitorpropane-1, Formalin, Methanal, Methyl Aldehyde, Methylene Oxide.

Oxybenzone (benzophenone): 

  • What is it? Oxybenzone is an organic compound used in sunscreens.
  • Where to find it: Sunscreens
  • Why it’s a problem: Benzophenone has anti-thyroid effects by blocking thyroid hormone receptors and TPO. Oxybenzone is designed to be easily absorbed; a 2008, study reported that oxybenzone was found in the urine of 97% of people tested. It’s also considered a hazardous eye irritant and allergen. Is causes hormone disruption in humans, affecting estrogen production in women and testosterone production in men.
  • Aliases: Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-

SLS / Sodium laureth sulfate:

  • What is it? A soap-like compound that lathers easily.
  • Where to find it: SLS is commonly used in cosmetics as a detergent and also to make products bubble. It is found in most conventional shampoos, shower gels, facial cleansers and dish soap.
  • Why it’s a problem: Due to the manufacturing process they’re commonly contaminated with measurable amounts of chemicals ethylene oxide and 1,4-dioxane – known human carcinogens. While ethylene oxide and 1,4-dioxane are prohibited on Health Canada’s Cosmetic Ingredient hotlist, it is not controlled for as a contaminant of cosmetic manufacturing. Health Canada has categorized sodium laureth sulfate as a “moderate human health priority” and flagged it for future assessment under the government’s chemical management plan, but for now it’s unregulated and found in in most shampoos, soaps and body washes.
  • Aliases: sulfuric acid monododecyl ester sodium salt, sodium salt, hydrogen sulfate, dodecyl alcohol, sodiumdodecanesulfate, and sodium monododecyl sulfate


  • What is it? Fluoride is an inorganic, monatomic anion with the chemical make up very similar to iodine (needed to make thyroid hormones).
    Where to find it: Toothpaste
  • What it’s a problem: Studies show that fluoride negatively impacts TSH and free thyroid hormone levels, even when you’re exposed to the accepted ‘safe’ concentration of less <0.5 mg/L. Fluoride also inhibits T4 to T3 conversion by interfering with deiodinases enzymes that convert T4 to T3, leaving you with less biologically active T3. T3 is important for your metabolism and energy production and fluoride exposure can lead to under diagnosis of hypothyroidism since TSH (the marker your GP uses to screen for thyroid disease) may look normal even when T3 levels are suboptimal. Prolonged fluoride exposure can even shut down thyroid gland function.
  • Aliases: Acidulated Phosphate Fluoride, Atomic number 9, Calcarea Fluorica, Fluorophosphate


  • What is it? Chemical derivatives of phenol that are often used as preservatives in makeup and skin care.
  • Where to find it: Lipsticks and moisturizers.
  • Why it’s a problem: The International Agency for Research on Cancer classifies BHA as a possible human carcinogen and definite endocrine disruptor. The European Commission on Endocrine Disruption has also listed BHA as a Category 1 priority substance, based on evidence that it interferes with hormone function. Long-term exposure to high doses of BHT has been proven to be toxic in mice and rat studies (this is the primary way we study substances & medications for human use in cases where using a human subject is deemed unethical) , causing liver, thyroid and kidney problems and affecting lung function.
  • Aliases: butylated hydroxyanisole + butylated hydroxytoluene


  • What is it? DEA is a chemical compound used to make cosmetics foamy, creamy or sudsy.
  • Where to find it: DEA is mainly found in moisturizers, sunscreens, soaps, cleansers, and shampoos.
  • Why it’s a problem: Exposure to high doses of these chemicals has been shown to cause liver cancers and precancerous changes in skin and thyroid. The European Union classifies DEA as harmful on the basis of danger of serious damage to health from prolonged exposure.
  • Aliases: diethanolamine


  • What is it? Despite being a known endocrine-disruptor with lasting effects on hormones and fertility (it’s banned in the EU!) Triclosan is a common antibacterial agent added to water-based skin care products.
  • Where to find it: You’re likely to find them in liquid products like foundations, concealer, mascara and lipgloss along with antiperspirants/deodorants, cleansers, and hand sanitizers as a preservative and an anti-bacterial agent.
  • What it’s a problem: Triclosan can pass through skin (studies show 75% of Americans have triclosan in their urine) and preliminary research shows that it likely interferes with hormone function. Environment Canada has categorized triclosan as toxic to aquatic organisms, bio-accumulative, and persistent – meaning it doesn’t breakdown easily and will end up in our water supply. It’s also believe that the extensive use of triclosan in beauty products may contribute to antibiotic-resistant bacteria.
  • Aliases: Irgasan DP-300, Lexol 300, Ster-Zac, Cloxifenolum


  • What is it? Parabens are the most widely used preservative in cosmetics.
  • Where to find it: Used as a preservative in many conventional personal care products (an estimated 75 to 90% of cosmetics contain parabens). They are also used as fragrance ingredients; as these recipes are considered trade secrets manufacturers are not required to disclose parapets in their list of ingredients.
  • Why it’s a problem: Parabens are rapidly absorbed through the skin and stored in our body tissues. Parabens have been detected in breast tumor tissues and are known to have hormone disrupting effects. It has been estimated that women are exposed to 50 mg per day of parabens from cosmetics and studies conducted by the CDC found four different parabens in human urine samples, indicating cumulative exposure despite the “very low” / “safe” levels found in beauty products.
  • Aliases: Methylparaben, butylparaben, propylparaben, isobutylparaben, ethylparaben, etc.)


  • What is it? The term fragrance on a cosmetic ingredients list represents a complex mixture of dozens of chemicals; over 3,000 chemicals are approved for use as fragrances in Canada.
  • Where to find it: perfumes, most personal care products – the word “fragrance” provides an opportunity for manufacturers to hide a lot of ingredients that don’t have to be listed on the label.
  • Why it’s a problem: Fragrances contain a number of endocrine disrupting chemicals; associated with thyroid disease, infertility, hormonal cancers, and early menopause. One common EDC found in perfumes called DEP, used to make smells last longer, is a known cause of hypothyroidism. “Fragrance” is also a term that is unregulated in Canada and there are thousands of chemicals that can be hidden in beauty products by simply calling them ‘fragrance’
  • Aliases: natural fragrance, perfume


  • What is it? These are chemicals mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity.
  • Where to find them: Perfume, hair spray, deodorant, almost anything fragranced (shampoo, laundry detergent, etc.) nail polish and insect repellent. DEHP is a particularly worrisome form of phthalate that is found in personal care products.
  • Why it’s a problem: Phthalates are thought to mimic and displace hormones and interrupt their production which can have a range of unpleasant effects including menstrual irregularities, infertility and hormonally-dependant cancers. Phthalates have been shown to cause infertility in both animals and humans and researchers believe that these changes to fertility can be passed on from generation to generation. Sperm counts have dropped significantly over the past few decades and these study results suggest that a parent’s exposure to endocrine disrupting chemicals can actually affect their baby’s future fertility.
  • Aliases: DBP (di-n-butyl phthalate), DEP (diethyl phthalate), DEHP (di-(2-ethylhexyl) phthalate or bis (2-ethylhexyl) phthalate), BzBP (benzylbutyl phthalate), and DMP (dimethyl phthalate)

How to Switch to Clean Beauty:

Start with exposure: 

Start by taking a look at your makeup bag, bathroom & shower caddy and think about which of these products cover the most surface area on your body. For most people this is body lotion, foundation, deodorant and blush / bronzer. Replace these products first since they cover such a large area and are used with consistency. We also encourage you to purchase a few clean lip sticks / lip balms since these products have direct access to your digestive tract through your mouth (your lips are at the end of the digestive system, now you know!). We’ve been committed to cleaner cosmetics for over a decade now and just recently switched to a natural mascara (Ilia lengthening mascara is everything!), so there’s no need to go full tilt when you’re just starting out.

Transition to ‘Clean’ beauty as you finish up old product:  

This is our top tip for transitioning to cleaner beauty products because it is far less wasteful than doing a full makeup kit overall. Slowly replace your old favourites with clean beauty dupes. Not only will you feel less overwhelmed but this strategy also gives you more time to ‘research’ your next purchase. Ask those ‘granola’ girlfriends of yours which brands they’re using, or check out some green beauty blogs for clean cosmetic inspiration.

Trusted Clean Makeup Brands

The world of clean beauty has changed so much over the past decade. Us haute hippies now even have a ton of chic and effective beauty options available at Sephora! These are our tested and approved clean beauty brands and go-to products if you’re looking for a place to start:

ILIA – Their lipstick is everything:

  • Tint Skin – combines skincare + SPF + light coverage, it’s perfect for that sheer barely-there makeup look.
  • Tinted Lip Conditioner – we’re obsessed with these sheer, hydrated lipsticks & own them in almost every shade. Arabian Knights + Nobody’s Business are favourites.
  • Mascara – This is one of our all-time favourite products; the mascara that finally made us given up our lance obsession.

RMS Beauty – This brand was our first experience with clean beauty and it set the bar really high. Their make up is creamy, dreamy and very natural:

  • Un Cover-up Concealer – thick enough to cover dark bags and blemishes while feeling light and moisturizing on the skin.
  • Living luminizer – this holy-grail product is a favourite of every clean beauty blogger and eco-conscious celeb. Give it a try and you’ll see why.
  • Lip to Cheek – this 2 in 1 lip and cheek tint comes in gorgeous vibrant colours and is a great place to start if you’re looking for a fun way to start experimenting with natural beauty.

Alumier MD – we loved this line so much we’re going to start carrying it in the clinic + our online store (stay tuned):

  • Sheer Hydration Broad Spectrum Sunscreen SPF 40 – physical sunscreen (meaning zinc replaces ozybenzone as the protective ingredients) provides powerful broad-spectrum protection against harmful UVA and UVB rays while moisturizing & protecting your skin with vitamin E, resveratrol and grapeseed extract.
  • Retinol Resurfacing 1.0 – While retinol is somewhat controversial in the clean beauty space there’s nothing like it when it comes to preventing fine lines and wrinkles. This version works! but is also free or parabens, SLS, etc.

Beauty Counter – while we’re not normally a fan of ‘MLM’ this make up line is just too good to write-off, their products speak for themselves (not all of them, and we have to admit quite a few are over priced, but they have some serious must-have beauty products):

  • The Clean Deo – we’ve been waiting months for this to arrive to Canada and it was well worth the wait. The smells are lovely (we’re partial to rose), packaging 10/10 & best of all they really work.
  • Overnight Resurfacing Peel – one of those ‘maybe a little more expensive than it should be but still incredible products’. Slap this on before bed under your favourite serum and you’ll wake with noticeably glowy skin.
  • Conditioning Lipstick – Pearl is the perfect subtle wear to work colour that leaves our lips moisturized and a tiny bit shimmery.

Misc – we pick up a the following miscellaneous one-off products from our favourite online retailer the detox market:

  • Vintner’s Daughter Serum – it’s quite the splurge, but totally worth it. One bottle lasts almost 6 months and our skin has never looked better.
  • Rahua Shampoo – smells like palo Santo and leaves hair squeaky clean for days while somehow keeping it soft and moisturized.
  • Fit Glow lip Serum – hydrating and plumping (actually works) with beautiful colours. We’ve partial to ‘Liv’ a sheer but bright pink.
  • Takesumi Dry Shampoo – shake it into your hair before bed and it magically removes all the greasy without contributing to a lot of build up on the scalp.
