Cosmetics have been a part of human culture for thousands of years, with the earliest recorded use of cosmetics dating back to ancient Egypt. Over time, the industry has grown exponentially, with a seemingly endless variety of products available to consumers. However, with so many options to choose from, it can be difficult to know what ingredients are used in these products and what impact they may have on our bodies and the environment.
Mercury and other dangerous cosmetic chemicals have a long history of use as an ingredient in cosmetics, dating back to ancient times. The ancient Egyptians, Greeks, and Romans all used mercury in various forms for their beauty routines.
In ancient Egypt, mercury was used in the form of a red powder called cinnabar, which was used as a cosmetic to color the cheeks and lips. Cinnabar was also used to make a type of eye paint called kohl, which was applied to the eyes and thought to have medicinal properties.
In ancient Rome, women used a white lead and mercury ingredient mixture called cerussa to whiten their skin. This mixture was also used to cover scars and blemishes.
From common ingredients found in everyday products to new and emerging ingredients, we will explore the benefits and potential risks associated with their use. Whether you’re a seasoned beauty enthusiast or just starting to build your skincare routine, this exploration will help you make informed decisions about the products you use.

Emollients – A Protective Cosmetic Ingredient
Emollients are a type of ingredient commonly found in skincare products. They work by creating a protective barrier on the skin’s surface, helping to lock in moisture and prevent water loss. This can help improve the skin’s texture, reduce dryness and flakiness, and even alleviate symptoms of certain skin conditions such as eczema.
Emollients come in many different forms, including oils, butters, and waxes. See INCI names. Some common emollients found in cosmetics and personal care products include:
- Mineral oil – a lightweight, odorless oil that is commonly used in moisturizers and makeup removers.
- Petrolatum – a thick, occlusive emollient that is often used in ointments and balms to help soothe dry, cracked skin.
- Shea butter – a rich, nourishing emollient derived from the nuts of the shea tree. It is often used in body butters and creams to help moisturize and soften the skin.
- Cocoa butter – another nourishing emollient derived from cocoa beans. It is commonly used in body lotions, lip balms, and other moisturizing products.
- Jojoba oil – a lightweight, non-greasy oil that is similar in composition to the natural oils produced by the skin. It is often used in facial serums and moisturizers to help balance and hydrate the skin.
While emollients are generally considered safe, it is important to note that some individuals may be sensitive to certain types of emollients, particularly those with oily or acne-prone skin. It is always a good idea to patch test a new product before applying it all over your face or body.
Emollients are an important ingredient in cosmetics and personal care products, helping to keep the skin hydrated and healthy.
Humectants – A Water Attracting Cosmetic Ingredient
Humectants are a type of ingredient commonly found in skincare products, particularly those designed to hydrate the skin. They work by attracting water molecules from the surrounding environment and binding them to the skin, helping to keep it hydrated and plump.
Some common humectants found in cosmetics and personal care products include:
- Glycerin – a clear, odorless liquid that is widely used in moisturizers, cleansers, and other skincare products.
- Hyaluronic acid – a natural molecule found in the skin that can hold up to 1,000 times its weight in water. It is often used in serums and moisturizers to help hydrate and plump the skin.
- Urea – a humectant and mild exfoliant that can help soften and smooth the skin.
- Aloe vera – a plant extract known for its hydrating and soothing properties. It is often used in after-sun products and other skincare products designed to calm and hydrate the skin.
- Honey – a natural humectant that is rich in antioxidants and antibacterial properties. It is often used in facial masks and other skincare products to help hydrate and brighten the skin.
While humectants can be highly effective at keeping the skin hydrated, it is important to note that they can also be drying if used in excess. This is because they can draw water from the deeper layers of the skin if the surrounding environment is too dry. It is important to use humectants in moderation and to always follow up with a moisturizer or other occlusive product to help lock in hydration.
Humectants are a valuable ingredient in skincare products, helping to keep the skin hydrated and healthy. However, it is important to use them wisely to avoid any potential drying effects.
Surfactants are a type of ingredient commonly found in skincare products that help to cleanse the skin by removing dirt, oil, and other impurities. They work by breaking down the surface tension of water, allowing it to more easily penetrate and remove dirt and oil from the skin.
Some common surfactants found in cosmetics and personal care products include:
- Sodium lauryl sulfate – a strong, effective surfactant that is often used in body washes and facial cleansers to deeply cleanse the skin.
- Cocamidopropyl betaine – a milder surfactant that is often used in gentle cleansers and shampoos.
- Sodium cocoamphoacetate – a mild, gentle surfactant that is often used in baby products and other sensitive skin formulations.
- Sodium lauryl sarcosinate – a mild, foaming surfactant that is often used in facial cleansers and other products designed for sensitive skin.
While surfactants can be very effective at removing dirt and oil from the skin, they can also be harsh and irritating if used in high concentrations or on sensitive skin. It is important to choose products with surfactants that are appropriate for your skin type and to use them in moderation to avoid over-drying or stripping the skin. Additionally, some surfactants can be environmentally harmful, so it is important to choose products with surfactants that are biodegradable and sustainable whenever possible.
Natural Ingredients in Cosmetics
As consumers become more conscious about the products they use, there has been a growing demand for natural ingredients in cosmetics. Natural ingredients are derived from plants, minerals, and other natural sources and are perceived as healthier and safer alternatives to synthetic ingredients. In this chapter, we will explore the benefits of natural ingredients in cosmetics and some of the most popular natural ingredients used in cosmetics today.
Benefits of Natural Cosmetic Ingredients
Natural ingredients offer a range of benefits for the skin and hair. They are gentle and safe to use, even for those with sensitive skin. Natural ingredients are free from harsh chemicals, synthetic fragrances, and preservatives that can cause irritation and allergic reactions. They are also biodegradable and eco-friendly, making them a sustainable choice for the environment. Look for ACA certified cosmetics and beauty products that meet standards for natural ingredients.
Furthermore, natural ingredients are often rich in vitamins, minerals, and antioxidants that nourish and protect the skin and hair. For example, some natural ingredients like aloe vera, chamomile, and lavender have anti-inflammatory properties that soothe and calm the skin. Others, like argan oil, coconut oil, and jojoba oil, are rich in fatty acids that moisturize and nourish the skin and hair.

Preservatives in Cosmetic Ingredients
Preservatives play a crucial role in cosmetics by preventing the growth of bacteria, mold, and yeast. Without them, cosmetics would quickly become contaminated and unsafe for use. However, there has been some concern about the safety of certain preservatives, and as a result, some companies have started to market “preservative-free” products. In this chapter, we’ll take a closer look at preservatives in cosmetics and examine their safety.
Why are preservatives necessary in cosmetics?
As mentioned, preservatives are essential in cosmetics to prevent contamination and spoilage. When cosmetics are exposed to air, moisture, and bacteria, they can quickly become a breeding ground for microorganisms, which can cause skin irritations, infections, and other health problems. Preservatives work by inhibiting the growth of these microorganisms, thereby extending the shelf life of the product and making it safer for use.
What are the common preservatives used in cosmetics?
There are many different types of preservatives used in cosmetics, including:
- Parabens – These are the most commonly used preservatives in cosmetics. They are effective against a wide range of microorganisms and have been used in cosmetics for over 50 years.
- Formaldehyde releasers – These preservatives work by slowly releasing formaldehyde into the product over time. Formaldehyde is a known carcinogen, which has led to concerns about the safety of these preservatives.
- Organic acids – These include benzoic acid, sorbic acid, and their salts. They are effective against fungi and some bacteria, but not as broad-spectrum as other preservatives.
- Quaternary ammonium compounds – These are cationic surfactants that have both preservative and conditioning properties. They are effective against bacteria, but not as effective against fungi and yeast.
- Phenoxyethanol – This preservative is effective against bacteria and fungi and is often used in combination with other preservatives.
Are preservatives safe for use in cosmetics?
The safety of preservatives in cosmetics has been a topic of debate for many years. Some preservatives, such as parabens and formaldehyde releasers, have been linked to health concerns such as endocrine disruption and skin irritation. However, it’s important to note that preservatives are used in cosmetics at very low levels and have been extensively tested for safety.
The use of preservatives in cosmetics is regulated by various organizations, including the FDA, the European Commission, and the International Fragrance Association. These organizations set limits on the amount of preservatives that can be used in cosmetics and require that they are tested for safety before they can be marketed.
Active Cosmetic Ingredients in Skincare
When it comes to skincare, many consumers are looking for products that not only feel good on their skin but also deliver real results. This is where active ingredients come in. Active ingredients are substances that have been scientifically proven to provide a specific benefit to the skin, such as reducing the appearance of fine lines and wrinkles or brightening the complexion.
There are many active ingredients used in skincare products, each with their own unique benefits. Here are a few of the most commonly used active ingredients and what they do:
- Retinoids: Retinoids and Retinol are derivatives of vitamin A and are known for their anti-aging properties. They work by increasing cell turnover, which helps to reduce the appearance of fine lines and wrinkles, and they can also help to even out skin tone and reduce the appearance of dark spots.
- Vitamin C: Vitamin C is a powerful antioxidant that can help to brighten the complexion and even out skin tone. It also helps to protect the skin from environmental damage and can help to stimulate collagen production, which can help to reduce the appearance of fine lines and wrinkles.
- Alpha Hydroxy Acids (AHAs): AHAs are a group of acids that are commonly used in skincare products to exfoliate the skin. They work by breaking down the bonds between dead skin cells, which helps to reveal smoother, brighter skin. AHAs can also help to reduce the appearance of fine lines and wrinkles and improve skin texture.
- Beta Hydroxy Acid (BHA): BHA is a type of acid that is commonly used in skincare products to exfoliate the skin. It works by penetrating deep into the pores to break down the buildup of oil and dead skin cells, which can help to reduce the appearance of acne and improve skin texture.
- Niacinamide: Niacinamide is a form of vitamin B3 that can help to improve the appearance of fine lines and wrinkles, reduce the appearance of dark spots, and improve skin texture. It also helps to strengthen the skin barrier, which can help to protect the skin from environmental damage.
- Hyaluronic Acid: Hyaluronic acid is a type of molecule that is naturally found in the skin and helps to keep it hydrated. When used in skincare products, it can help to plump up the skin and reduce the appearance of fine lines and wrinkles.
- Peptides: Peptides are small chains of amino acids that can help to stimulate collagen production in the skin. They can help to improve the appearance of fine lines and wrinkles and improve skin texture.
New molecules are being created with the help of artificial intelligence AI to develop skincare products like Fibroquin and other new skincare treatments.
When choosing skincare products that contain active ingredients, pay attention to the concentration of the active ingredient and to use products as directed. Some active ingredients, such as retinoids and AHAs, can cause skin irritation if used too frequently or in high concentrations, so it’s important to start slowly and build up to higher concentrations over time. Additionally, it’s important to use sunscreen daily when using active ingredients, as they can make the skin more sensitive to the sun.
