Harmful Skincare Ingredients to Avoid - Ingredient Safety Guide

A major transparency revolution is happening in the beauty industry now. For many years, manufacturers have been putting all sorts of complex chemical compounds in our beauty care products, and we had no idea what they were or even how to pronounce them. We have seen a huge shift from "Clean Beauty" being a niche or low-volume trend to now being a global standard because consumers want to know what is being placed on their skin, and in response to the emergence of "greenwashing", it is more difficult to distinguish between safety and marketing terminology.

In this guide, we will help you to identify the red flags within your vanity by breaking down the harmful skincare ingredients and giving you a good way to achieve a cleaner, healthier, and more transparent skincare routine.

Why You Should Care About Harmful Skincare Ingredients

Your skin is absorbent! Studies show that up to 80% of everything you put on your skin gets absorbed into your bloodstream. While using synthetic preservatives on rare occasions is unlikely to have a major impact on your health, it is the "Cocktail Effect" (the accumulation of multiple types of chemicals from dozens of different products, over the course of many days) that experts find concerning. 

By learning to identify harmful skincare ingredients and knowing how to spot them, you will empower yourself to learn how to protect yourself from the risks of developing chronic irritations, disrupting hormones and causing long-term damage to the environment.

The "Dirty List": Ingredients to Avoid in Clean Beauty

When you start to look for a clean beauty product, one of your first steps will be to flip over the back of the product and see what is on that ingredient list. These are the types of ingredients you want to avoid, according to experts:

1. Parabens (Methyl, Ethyl, Propyl, Butyl)

Parabens are very cheap preservatives that are used to stop mold and bacteria from growing. As they can act like oestrogen in the body, they disrupt the endocrine system. Some studies have found that they may be linked with problems with reproduction and can even be found in breast cancer tissue.

2. Sulfates (SLS and SLES)

Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) are the surfactants that create the suds in many of the lotions and shampoos we use. They are often too harsh for your skin and will remove the natural oils, causing damage to your natural barrier. The effect of removing the natural oils can be dry, red, and sensitive skin.

3. Phthalates

Many phthalates are hidden behind the blanket term 'fragrance.' Phthalates help the longevity of a scent and soften plastics. Like parabens, phthalates are also endocrine disruptors and are linked with both developmental and reproductive toxicity.

4. Synthetic Fragrances

The fragrance loophole in the industry is one of the most significant difficulties in the industry. There are no requirements for manufacturers to disclose the various chemicals in their fragrances. Fragrance in skincare risks include allergic reactions, headaches, and can lead to respiratory problems. If you are interested in buying clean beauty products, look for either essential oils or "fragrance-free" options.

Identifying Toxic Beauty Ingredients in Your Daily Routine

Although most people have heard of the "big three" (parabens, sulfates, and phthalates), there are several other toxic beauty ingredients that often get overlooked. Some examples include:

• Formaldehyde Releasers:  They are usually found in DMDM hydantoin or Diazolidinyl urea. This is actually two different chemicals used to slowly deliver formaldehyde—an established carcinogen—to keep a product from going bad.
• Mineral Oil and Petrolatum: While these two ingredients are natural (derived from crude oil), they can block pores and are frequently not sustainably-sourced.
• Chemical Sunscreens (Oxybenzone & Avobenzone): These products can cause allergic reactions to skin, and they have been shown to damage coral reefs, so they should not be used if you are looking for eco-friendly skincare brands.
• Toluene: Often found in nail polish, toluene can be harmful to the immune system and can cause birth defects.

Your Non-Toxic Skincare Guide: How to Shop Smarter

Shopping for non-toxic skincare is overwhelming if you don’t have a reference guide. Follow these guidelines for an easier shopping experience.

1. Read the Full Label: Do not be fooled by the “Natural” or “Organic” claims on the front. Always read the back of the bottle.
2. Use Tech Tools: There are many apps, such as Think Dirty and EWG Skin Deep, that let you scan barcodes to get a safety rating for thousands of products.
3. Support Transparency: There are many brands that list all ingredients in their products, as well as details on their extracts.
4. Prioritise Local and Ethical: If you are looking for high-quality formulations, searching for best skin care NZ or locally made artisan products often leads you to brands that prioritise small-batch integrity over mass-produced chemical fillers.

The Environmental Impact of Conventional Beauty

Conventional beauty has harmful effects on the environment. Many harmful skincare ingredients are non-biodegradable, for example, microplastics and siloxanes. After you wash off your face with products containing these ingredients, they end up in our oceans through the waste, causing long-term damage to marine animals. By switching to more eco-friendly skincare products, you can help prevent further damage to healthy ecosystems around the world while getting a glowing complexion.

FAQ: Ingredients to Avoid in Clean Beauty

1. What are the most common harmful skincare ingredients to avoid? 

Parabens, sulfates, and phthalates are considered to be the “big three.” Parabens are known to disrupt hormones; sulfates cause severe irritation on the skin; and disrupt the body’s pH, especially parts normally protected by the acid mantle. Phthalates have been associated with reproductive problems. Therefore, it is important for consumers to always read the clean beauty ingredient lists for these preservatives and surfactants.

2. Why is fragrance considered a toxic beauty ingredient? 

 "Fragrance" is a loophole within applicable law that allows manufacturers to hide many potentially toxic chemicals—over 3000 total—including phthalates under just one name ("fragrance"). Therefore, you could be unknowingly using products containing many toxic substances when using “clean” beauty products with the word “fragrance”. The aforementioned phthalates have adverse effects on our health by causing migraines, respiratory concerns, and chronic allergic conditions. To minimize expos will help you avoid the use of toxic fragrances in beauty products, try finding an eco-friendly skincare brand that uses either essential oils as fragrance, or has clear/non-confusing labelling where you will easily identify fragrances.

3. How do I transition to a non-toxic skincare guide? 

Start replacing products that cover a large surface area, such as moisturiser and facial cleansers or toners. Choose skin care brands or from local artisans that use botanical actives in their products, as opposed to using toxic beauty ingredients such as mineral oil or formaldehyde-releasing ingredients.

Conclusion: Empowering Your Beauty Ritual

Understanding harmful skincare ingredients is not about fearing the ingredients involved but rather about ensuring your makeup choices reflect your knowledge and understanding of the ingredients. By removing toxic beauty ingredients from your skin routine, you are supporting your body’s long-term health and well-being. Further, you are being an eco-conscious user.

If you are searching for specialised skin care products from New Zealand or global eco-friendly skin care brands, locate the power in your ability to read product labels. Once you identify your most frequently used products (e.g., moisturiser and cleanser) that you want to replace, in no time you will have made your complete beauty ritual a source of well-being rather than apprehension. Beauty should never involve compromising your health.
