How to Avoid Toxic Ingredients in Skincare (Updated 2025)

Skincare is an essential part of our daily routine, but have you ever wondered what ingredients are lurking in your favourite products? The truth is, many skincare products on the market today contain toxic ingredients that can have harmful effects on our bodies and the environment. From parabens and phthalates to synthetic fragrances and sulfates, it’s more important than ever to educate ourselves on what to avoid.

I’m not sure about you, but I find it very confusing and daunting trying to decipher the ingredients on my skincare products! The good news? In 2025, the clean beauty movement has gained tremendous momentum, with regulatory changes finally catching up to consumer demand for safer products.

The Reality Check: The average American adult uses about 12 personal care products daily, resulting in exposure to an average of 168 chemicals. While the European Union has banned over 2,400 toxic chemicals from personal care products, the FDA has historically restricted only about a dozen, though this is finally beginning to change in 2025.

Let’s look at the top toxic ingredients commonly found in skincare products, why they should be avoided, the latest regulatory updates, and provide alternative options for safer skincare. So grab your favourite moisturiser and get ready to dive into the world of clean skincare!

Recent Regulatory Progress (2025 Update)

Several significant legislative developments are reshaping skincare safety in 2025:

State-Level Bans:

• Washington State’s Toxic-Free Cosmetics Act took effect January 1, 2025, restricting certain toxic chemicals in cosmetics
• California, Oregon, Vermont, and Maryland have all implemented bans on harmful ingredients
• These states are leading the way in consumer protection

Federal Legislation: The “Safer Beauty Bill Package” has been reintroduced in Congress, which would:

• Ban two entire classes of chemicals (phthalates and formaldehyde-releasing preservatives)
• Prohibit 18 of the most hazardous chemicals, including mercury, formaldehyde, and lead
• Require transparency in ingredient disclosure
• Protect communities of colour and salon workers who face disproportionate exposure

While these changes are promising, it’s still crucial to be your own advocate when choosing skincare products.

1. Parabens: Hidden Dangers in Your Skincare Products

Parabens have long been used as preservatives in skincare products to extend their shelf life. However, studies continue to raise concerns about their potential health risks. Parabens can mimic estrogen in the body, disrupting hormonal balance and potentially leading to reproductive issues and even breast cancer.

What to Look For: Methylparaben, ethylparaben, propylparaben, butylparaben, isopropylparaben, isobutylparaben

Current Status: Several states have banned certain parabens (isopropyl and isobutyl parabens) as of 2025, with more restrictions likely coming.

Safer Alternatives: Look for skincare products labelled “paraben-free” and opt for natural preservatives such as grapefruit seed extract, rosemary extract, or vitamin E.

2. Phthalates: The Silent Threat to Your Skin

Phthalates are commonly used as plasticisers in skincare products to improve texture and enhance fragrance. They have been linked to hormone disruption, reproductive issues, and developmental abnormalities. The greatest concern lies in their potential impact on pregnant women and children.

What to Look For: Diethylphthalate (DEP), dimethylphthalate (DMP), dibutylphthalate (DBP), diethylhexyl phthalate

Current Status: Washington, Oregon, and Vermont have banned ortho-phthalates in cosmetics as of 2025. The federal Toxic-Free Beauty Act proposes banning the entire class of ortho-phthalates.

Safer Alternatives: Choose products labelled “phthalate-free” or opt for natural fragrances derived from essential oils.

3. Sulfates: The Foaming Agents That Strip Your Skin

Sulfates, such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), are commonly used in skincare products to create a rich lather. However, they can strip the skin of its natural oils, leading to dryness, irritation, and even allergic reactions. Sulfates are also harsh on the environment, as they are not easily biodegradable.

What to Look For: Sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES)

Safer Alternatives: Look for sulfate-free cleansers and opt for gentle surfactants derived from natural ingredients like coconut or sugar.

4. Synthetic Fragrances: A Recipe for Irritation

Synthetic fragrances are widely used in skincare products to create appealing scents. However, “fragrance” is a catchall term that can encompass hundreds of chemicals—and because it’s considered a trade secret under federal law, manufacturers aren’t required to disclose what’s in it.

These fragrances can contain a cocktail of potentially harmful chemicals, including phthalates and allergens, causing skin irritation, allergies, and sensitivities, especially for those with sensitive skin.

What to Look For: “Fragrance,” “parfum,” or “perfume” on the ingredient list

2025 Trend: Consumers are increasingly demanding fragrance transparency, pushing brands to disclose specific essential oils and aromatic compounds.

Safer Alternatives: Opt for products labelled “fragrance-free” or choose skincare products scented with disclosed natural essential oils.

5. Formaldehyde: From Embalming Fluid to Skincare

Formaldehyde and formaldehyde-releasing preservatives are used to prevent microbial growth in skincare products. However, they are known carcinogens and have been linked to respiratory issues, allergies, and skin sensitisation. Prolonged exposure to formaldehyde can have serious health consequences.

What to Look For: Formaldehyde, quaternium-15, DMDM hydantoin, imidazolidinyl urea, paraformaldehyde, and methylene glycol

Current Status: The federal Toxic-Free Beauty Act proposes banning the entire class of formaldehyde-releasing chemicals. Several states already restrict these ingredients.

Special Concern: Chemical hair straightening treatments often contain formaldehyde and can cause serious lung and eye irritation.

Safer Alternatives: Choose skincare products that use natural preservatives like rosemary extract or grapefruit seed extract.

6. Mineral Oil: A Barrier to Healthy Skin

Mineral oil is a common ingredient in skincare products due to its low cost and ability to lock in moisture. However, it forms a barrier on the skin that can clog pores and prevent the skin from breathing. This can lead to acne breakouts, skin irritation, and other skin disorders.

What to Look For: Mineral oil, paraffinum liquidum, petrolatum

Safer Alternatives: Choose plant-based oils like jojoba oil, argan oil, or coconut oil as moisturisers for healthier, non-comedogenic skincare.

7. PEG Compounds: The Unseen Dangers in Skincare

Polyethylene glycol (PEG) compounds are commonly used in skincare products as thickeners, solvents, and moisture-carriers. However, they can disrupt the skin’s natural moisture balance, leading to dryness and accelerated aging. PEG compounds can also be contaminated with harmful impurities, including the potential carcinogen 1,4-dioxane.

What to Look For: Polyethylene glycol (PEG), poly(oxyethylene), or ingredients containing “PEG,” “polyethylene,” “polyoxyethylene,” “-eth-,” or “-oxynol-“

Safer Alternatives: Opt for skincare products that use natural thickeners and emollients like aloe vera gel, shea butter, or cocoa butter.

8. Triclosan: The Antibacterial Ingredient to Avoid

Triclosan is an antibacterial agent that has been linked to hormone disruption, antibiotic resistance, and environmental toxicity. While the FDA has banned triclosan in certain products, it may still be present in some skincare items.

What to Look For: Triclosan, triclocarban

Safer Alternatives: Choose natural antibacterial ingredients like tea tree oil, witch hazel, or neem oil for a healthier alternative.

9. Silicones: The Slippery Slope of Skincare

Silicones are commonly used in skincare products to create a smooth, silky texture and provide a temporary “plumping” effect. However, they can form a barrier on the skin that prevents it from breathing and can lead to clogged pores and breakouts. Silicone-based products can also be difficult to remove, leading to product buildup on the skin.

What to Look For: Ingredients ending in “-siloxane” or “-methicone”

2025 Perspective: While silicones aren’t necessarily harmful to health, the trend toward barrier-focused skincare emphasises ingredients that support rather than occlude the skin.

Safer Alternatives: Choose lightweight, water-based moisturisers and serums that provide hydration without relying on silicones.

10. PFAS: The “Forever Chemicals” (New to Watch in 2025)

PFAS (per- and polyfluoroalkyl substances) are long-chain chemicals used in some cosmetics for water resistance and texture. They’ve been linked to serious health concerns, including cancer, immune system effects, and developmental issues. PFAS are called “forever chemicals” because they don’t break down in the environment or the human body.

What to Look For: Ingredients containing “fluoro,” “perfluoro,” or “PTFE”

Current Status: California has banned certain PFAS in cosmetics effective January 2025. Many other states are following suit.

Safer Alternatives: Choose products specifically labelled “PFAS-free” or from brands committed to waterless beauty formulations.

11. Mercury Compounds: Still Present in Some Products

Despite being highly toxic to the nervous system and kidneys, mercury compounds can still be found in certain skin-lightening creams and anti-ageing products, particularly those imported from other countries.

What to Look For: Mercury, mercurous chloride, calomel, mercuric

Current Status: Mercury is restricted by the FDA to trace amounts (less than 1 ppm), but enforcement on imported products can be inconsistent.

Safer Alternatives: For skin brightening, look for vitamin C, niacinamide, or liquorice root extract.

Embrace Clean Skincare for a Healthier You

When it comes to skincare, knowledge is power. By understanding the potential risks associated with certain ingredients, you can make informed decisions about the products you choose to use on your skin.

The 2025 Clean Beauty Revolution

The clean beauty movement has evolved beyond just a trend—over 70% of consumers now prioritise eco-friendly, transparent skincare. Key trends shaping 2025 include:

• Barrier-focused skincare: Products designed to support and repair the skin’s natural protective barrier with ingredients like ceramides, probiotics, and postbiotics
• Biotech innovations: Lab-grown botanicals and fermented ingredients that provide potent, sustainable alternatives
• Waterless beauty: Concentrated formulations that reduce packaging waste and eliminate the need for preservatives
• Minimal ingredient lists: Fewer, carefully selected ingredients that reduce irritants and allergens
• Radical transparency: Brands using QR codes and blockchain technology to provide complete ingredient sourcing information
• AI-driven personalisation: Custom formulations based on individual skin analysis

How to Choose Safer Products:

1. Read ingredient labels carefully and look for products free from the toxic ingredients listed above
2. Research brands’ sustainability sections to understand their commitment to clean formulations
3. Look for certification labels like EWG Verified, Made Safe, or Leaping Bunny
4. Use resources like EWG’s Skin Deep database to check product safety ratings
5. Be sceptical of “green” or “natural” marketing—these terms aren’t regulated, so always check the actual ingredients
6. Choose products that harness natural ingredients like essential oils, plant extracts, and nourishing botanicals
7. Consider certified organic options for additional assurance about ingredient quality

Whether you’re looking for an everyday moisturiser or specialised treatments like eczema cream, choose products that prioritise your skin’s health with clean, transparent formulations.
