The answer to this question is multi-faceted. Indeed, if you choose to use only ONE product ONCE a day, the risk of developing adverse side-effects to that product are likely relatively low. When we consider just HOW MANY PRODUCTS we use daily as well as where we live, the types of foods we consume and water we drink, we've got to consider the probable impact of our consumption. It's important to understand the terms Bioaccumulation and Biomagnification and what they mean to us. In simple terms, the more products we consume with harmful ingredients, the greater the likelihood of developing toxicity in the body, which can manifest as disease.

We've always got to consider the CUMULATIVE impacts of our consumption.

"FDA does not have the same legal authority to require allergen labeling for cosmetics as for food. So, if you are concerned about fragrance sensitivities, you may want to choose products that are fragrance free, and check the ingredient list carefully. If consumers have questions, they may choose to contact the manufacturer directly."
"The International Fragrance Association (IFRA) lists 3,059 materials that are reported as being used in fragrance compounds. Of these 3,059 ingredients, some have evidence linking them to health effects including cancer, reproductive toxicity, allergies and sensitivities.
A 2016 study assessed self-reported health effects from fragrance. This survey of a random sample of US residents found that 99.1% of participants are exposed to fragranced products at least once a week from their own use, others’ use, or both. Participants also reported an extensive list of health effects experienced when exposed to fragrance ranging from migraines and asthma to gastrointestinal problems and cardiovascular problems.
VULNERABLE POPULATIONS: All, especially pregnant women, infants"
"Parabens are a family of related chemicals that are commonly used as preservatives in cosmetic products. Preservatives may be used in cosmetics to prevent the growth of harmful bacteria and mold, in order to protect both the products and consumers.
The parabens used most commonly in cosmetics are methylparaben, propylparaben, butylparaben, and ethylparaben.
Product ingredient labels typically list more than one paraben in a product, and parabens are often used in combination with other types of preservatives to better protect against a broad range of microorganisms.
FDA doesn’t have special rules that apply only to preservatives in cosmetics. The law treats preservatives in cosmetics the same as other cosmetic ingredients."
"Personal care products are the greatest contributors to paraben exposure, as seen in studies comparing paraben levels in the bodies of women, men, adolescents and children who regularly use cosmetics and those who do not. Adolescent girls who wear makeup every day had 20 times the levels of propylparaben in their urine compared to those who never or rarely wear makeup (Berger 2018). The use of body and face lotions, hair products, sunscreens and makeup have all been predictors of and correlated with remarkably increased levels of urinary parabens (Sahki 2018, Nassan 2017, Braun 2014 and Fisher 2017).
Parabens can act like the hormone estrogen in the body and disrupt the normal function of hormone systems affecting male and female reproductive system functioning, reproductive development, fertility and birth outcomes. Parabens can also interfere with the production of hormones."
Originally extracted from Coal Tar, now is produced from Petroleum.
"Phthalates are a group of chemicals used in hundreds of products, such as toys, vinyl flooring and wall covering, detergents, lubricating oils, food packaging, pharmaceuticals, blood bags and tubing, and personal care products, such as nail polish, hair sprays, aftershave lotions, soaps, shampoos, perfumes and other fragrance preparations."
The American Academy of Pediatrics has published an article stating that infants exposed to infant care products, specifically baby shampoos, baby lotions, and baby powder, showed increased levels of phthalate metabolites in their urine (see “Baby Care Products: Possible Sources of Infant Phthalate Exposure,”External Link Disclaimer S. Sathyanarayana, Pediatrics, 2008, vol. 121, pp. 260-268).
Canada's Protecting It's Population:
Recent studies in human populations confirm some of the adverse impacts of DEHP on male reproductive tract development first identified in many experimental animal studies. A systematic review also finds that higher exposures to DEHP are associated with sperm abnormalities and lower testosterone levels.
Recent studies also show that prenatal exposure to phthalates is associated with adverse impacts on neurodevelopment, including lower IQ, and problems with attention and hyperactivity,
and poorer social communication. Researchers at the Harvard School of Public Health have found that sick infants treated in neonatal intensive care units can have high exposure levels to this reproductive and development toxicant. Outside the health care setting, people are exposed to DEHP and other phthalates from a variety of sources, including beauty products, PVC toys, vinyl shower curtains, car seats, wallpaper, and many other consumer products. https://noharm-uscanada.org/issues/us-canada/phthalates-and-dehp
"Diethanolamine is used in a number of consumer products, such as shampoos, cosmetics, and pharmaceuticals. Acute (short- term) inhalation exposure to diethanolamine in humans may result in irritation of the nose and throat, and dermal exposure may irritate the skin. No information is available on the chronic (long-term), reproductive, developmental, or carcinogenic effects of diethanolamine in humans. Animal studies have reported effects on the liver, kidney, blood, and central nervous system (CNS) from chronic oral exposure to diethanolamine. The National Toxicology Program (NTP) reported an increased incidence of liver and kidney tumors in mice from dermal exposure to diethanolamine. EPA has not classified diethanolamine for carcinogenicity."
"Petrolatum comes from crude oil, and as such is not a renewable resource.
A study that was published in Pediatrics in 2000 found that extremely-low-birth-weight infants treated with petroleum jelly were more likely to develop systemic candidiasis; it created a warm, moist place for fungi to grow...petrolatum is an occlusive barrier, locking in moisture – but it does not allow moisture to be absorbed from the atmosphere
The EWG says – and governments and the CCTFA acknowledge – there is a risk of contamination from polycyclic aromatic hydrocarbons (PAHs), cancer-causing chemicals found in crude oil and its by-products. While no studies have ever shown a direct link between petrolatum and cancer, the European Union put numerous grades of petrolatum on a list of dangerous substances. Only highly refined petrolatum can be used in cosmetics there."
"When properly refined, petrolatum has no known health concerns. However, with an incomplete refining history, petrolatum could potentially be contaminated with polycyclic aromatic hydrocarbons, or PAHs. PAHs are byproducts of organic material combustion, commonly stored in fats upon exposure due to its lipophilic properties. There is no way to confirm proper refinement unless a complete refining history is provided.
HEALTH CONCERN: Cancer. The primary concern with petrolatum is the potential contamination with PAHs. The National Toxicology Program (NTP) considers PAHs as a class to contain reasonably anticipated carcinogens; the International Agency for Research on Cancer (IARC) lists 14 PAHs as probable or possible carcinogens and one PAH as a known carcinogen. A study on Long Island, NY, found that those women with high levels of PAH-DNA adducts had a 50 percent greater risk of breast cancer. The formation of PAH-DNA adducts, an indicator of PAH exposure, is linked to cancer development. 
VULNERABLE POPULATIONS: All populations
REGULATIONS: The EU mandates that for cosmetic use, the full refining history of the petrolatum must be known and proven to be non-carcinogenic. The US sets no requirements on refinement and the PAH content in the petrolatum used in personal care products."https://www.safecosmetics.org/get-the-facts/chemicals-of-concern/petrolatum/
Phenoxyethanol is thought to cause central nervous system damage in exposed infants.
"...FDA issued a warning about Mommy’s Bliss Nipple Cream (as Christine noted), “because the product contains potentially harmful ingredients that may cause respiratory distress or vomiting and diarrhea in infants.” The FDA warned consumers not to use the product (intended for nursing mothers), explaining:
Potentially harmful ingredients in Mommy’s Bliss Nipple Cream are chlorphenesin and phenoxyethanol. Chlorphenesin relaxes skeletal muscle and can depress the central nervous system and cause respiratory depression (slow or shallow breathing) in infants. Phenoxyethanol is a preservative that is primarily used in cosmetics and medications. It also can depress the central nervous system and may cause vomiting and diarrhea, which can lead to dehydration in infants." https://www.ourbodiesourselves.org/2008/05/fdas-mommys-bliss-nipple-cream-warning-disapp/
"Sodium laureth sulfate (sometimes referred to as SLES) is used in cosmetics as a detergent and also to make products bubble and foam. It is common in shampoos, shower gels and facial cleansers. It is also found in household cleaning products, like dish soap.
Depending on manufacturing processes, sodium laureth sulfate may be contaminated with measurable amounts of ethylene oxide and 1,4-dioxane. i The International Agency for Research on Cancer ethylene oxide as a known human carcinogen and 1,4-dioxane as a possible human carcinogen. Ethylene oxide can also harm the nervous system iiand the California Environmental Protection Agency has classified it as a possible developmental toxicant based on evidence that it may interfere with human development. iii 1,4-dioxane is also persistent. In other words, it doesn’t easily degrade and can remain in the environment long after it is rinsed down the shower drain. 1,4-dioxane can be removed from cosmetics during the manufacturing process by vacuum stripping, but there is no easy way for consumers to know whether products containing sodium laureth sulfate have undergone this process. iv
The industry panel that reviews the safety of cosmetics ingredients notes that sodium laureth sulfate can irritate the skin and eyes (though approving of its use in cosmetics). v
Health Canada has categorized sodium laureth sulfate as a “moderate human health priority” and flagged it for future assessment under the government’s Chemicals Management Plan."
Also called: PEG, Polysorbates, Laureth, Ethoxylated Alcohols, dioxan, p-dioxane, diethylene dioxide, diethylene oxide, diethylene ether and glycol ethylene ether
Found in products that foam.
"1,4-Dioxane is a likely human carcinogen and has been found in groundwater at sites throughout the United States. The physical and chemical properties and behavior of 1,4-dioxane create challenges for its characterization and treatment. It is highly mobile and does not readily biodegrade in the environment."
If you're curious about what our FDA has to say about Dioxane, read about it here:
"1,4-Dioxane enters the body when people breathe air or consume water or food contaminated with 1,4-dioxane. People can also be exposed following contact with cosmetics, shampoo, or bubble bath that contain certain ingredients in which 1,4-dioxane may be a contaminant. 1,4-Dioxane does not remain in the body because it breaks down into chemicals that are removed quickly. Breathing: 1,4-Dioxane for short periods of time causes irritation of the eyes, nose and throat in humans. Exposure to large amounts of 1,4-dioxane can cause kidney and liver damage. Cancer classifications: (based on inadequate evidence in humans and sufficient evidence in animals):
Sunscreen is another popular product that may contain formaldehyde.
FRIGHTENING FACT: Formaldehyde is a chemical used to embalm people--preserve them--after death.
"Formaldehyde is a sensitizing agent that can cause an immune system response upon initial exposure. It is also a cancer hazard. Acute exposure is highly irritating to the eyes, nose, and throat and can make anyone exposed cough and wheeze. Subsequent exposure may cause severe allergic reactions of the skin, eyes and respiratory tract. Ingestion of formaldehyde can be fatal, and long-term exposure to low levels in the air or on the skin can cause asthma-like respiratory problems and skin irritation such as dermatitis and itching. Concentrations of 100 ppm are immediately dangerous to life and health (IDLH). New products that often contain high levels of formaldehyde include
"The Food and Drug Administration ( FDA) has classified propylene glycol as an additive that is “generally recognized as safe” for use in food. It is used to absorb extra water and maintain moisture in certain medicines, cosmetics, or food products. It is a solvent for food colors and flavors, and in the paint and plastics industries. Propylene glycol is also used to create artificial smoke or fog used in fire- fighting training and in theatrical productions. Other names for propylene glycol are 1,2- dihydroxypropane, 1,2- propanediol, methyl glycol, and trimethyl glycol. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature. It may exist in air in the vapor form, although propylene glycol must be heated or briskly shaken to produce a vapor. Propylene glycol is practically odorless and tasteless."
"In the US, it can be used as a direct and indirect food additive. In Europe, it is only allowed to be used in food as a solvent for colors, emulsifiers, antioxidants and enzymes, with up to 0.45 grams per pound (1 gram/kg) allowed in the final food product (9Trusted Source).
The World Health Organization recommends a maximum intake of 11.4 mg of propylene glycol per pound of body weight (25 mg/kg) per day. The estimated exposure to propylene glycol through foods in the US is 15 mg per pound (34 mg/kg) per day (9Trusted Source).
However, as current intakes are estimated to be above the recommended level, it may be wise to reduce dietary sources where you can, especially as the primary sources are highly processed foods."
Phenol was first extracted from COAL TAR but today is produced by PETROLEUM.
FRIGHTENING FACT: Along with formaldehyde, phenols are also used in the embalming process.
"irritation to the skin, eyes, nose, throat, and nervous system. Some symptoms of exposure to phenol are weight loss, weakness, exhaustion, muscle aches, and pain. Severe exposure can cause liver and/or kidney damage, skin burns, tremor, convulsions, and twitching. Workers may be harmed from exposure to phenol.The level of harm depends upon the dose, duration, and work being done.
Phenol is used in many industries. It’s used for medicine as a slimicide, antiseptic, and disinfectant and to manufacture a number of products."
Aluminum is the #1 effective ingredient in Anti-Perspirant due to it plugging up sweat ducts to stop the flow of moisture to your skin.
FRIGHTENING FACTS: Lead is so toxic that it was banned from paint and gasoline but is a common ingredient in LIPSTICK. Arsenic is found in EYELINER. Cadmium and mercury are found in MASCARA.
The FDA allows for 10 ppm in lipstick.
"Although most cosmetics on the market in the United States generally already contain less than 10 ppm of lead, a small number contained higher amounts, and we are aware that some cosmetics from other countries contain lead at higher levels. This makes guidance on recommended maximum lead levels all the more important as more products are imported into this country."
To our knowledge, however, the FDA has not studied the cumulative affects of using or wearing multiple products daily.
"Heavy metal toxicity has proven to be a major threat and there are several health risks associated with it. The toxic effects of these metals, even though they do not have any biological role, remain present in some or the other form harmful for the human body and its proper functioning. They sometimes act as a pseudo element of the body while at certain times they may even interfere with metabolic processes. Few metals, such as aluminium, can be removed through elimination activities, while some metals get accumulated in the body and food chain, exhibiting a chronic nature.... Metal toxicity depends upon the absorbed dose, the route of exposure and duration of exposure, i.e. acute or chronic. This can lead to various disorders and can also result in excessive damage due to oxidative stress induced by free radical formation."
