Top 6 Useful Tips for Checking Cosmetic Ingredients

To check cosmetic ingredients, it's essential to have basic knowledge about the function of various ingredients and know how to read the ingredients list on a product. Since the FDA (Food and Drug Administration) does not mandate precise percentages for ingredients, the most reliable way to assess a product is by looking at the order in which ingredients are listed. According to ingredient listing regulations, the highest concentration ingredients appear first and are listed in descending order. However, ingredients present in concentrations below 1% may appear either before or after higher-concentration ingredients. This means that an ingredient with 0.01% could be listed before one with 0.9% in the product’s ingredient list.

When reviewing a skincare product, focus on the first few ingredients, as these make up the bulk of the product.

Typically, the ingredient list follows a general order from most to least abundant: Primary ingredients with the highest concentration – Active ingredients – Emulsifiers – Fragrances – Preservatives.

• For shampoos or facial cleansers, focus on the first 3 to 5 ingredients.
• For products like creams or serums, pay attention to the first 8 to 10 ingredients.
• Also, be cautious of any harmful ingredients present in the product to make the right choice.

However, for beginners, remembering the names and functions of ingredients can be tricky. Fortunately, there are numerous websites available to help users check cosmetic ingredients, so you can ensure you are getting accurate information.

CosDNA, short for Cosmetics DNA, is a website designed to check the ingredients in a cosmetic product, its effects, and the safety of the product. It is often described as a “cosmetic encyclopedia.” The site features products from major brands as well as popular labels from Japan, Korea, the UK, the US, and more. New products are regularly updated.

How to Use CosDNA:

Step 3: View the product analysis results from CosDNA. The results appear in a table with five columns:

• Ingredient: the ingredients found in the product.
• Function: the function of each ingredient.
• Acne: the potential of the ingredient to cause acne, with 5 being the highest risk and 1 the lowest. An empty space means the ingredient does not cause acne.
• Irriant: the potential for the ingredient to irritate the skin, rated similarly to acne.
• Safety: the safety level of the product, rated from 1 to 9, with green representing safe, yellow moderate, and red indicating high risk.

For sunscreen products, there is also an additional UV column, with black dots representing the level of protection against UVA and UVB rays.

Cosmetics are substances or products used to enhance or alter a person's appearance or body fragrance. These products are designed for use on the face, hair, body, and more. They typically consist of a blend of chemical compounds, some derived from natural sources (like coconut oil), while others are synthetically made. Common cosmetic products include lipstick, mascara, eyeshadow, foundation, blush, setting powder, facial cleansers, body lotions, shampoo, hair styling products, perfumes, and more.

Cosmetics have become increasingly essential for everyone, especially for women. Today, there are thousands of different cosmetics on the market, each with its unique combination of ingredients. Each product can contain anywhere from 15 to 50 ingredients, sometimes even more. According to research from American scientists, through the use of cosmetics, a woman is exposed to an average of about 515 chemicals in a single day.

However, most people are unaware of what they are putting on their skin, or more specifically, the ingredients in the cosmetics they use and the exact function of those ingredients. Any potential impact on health primarily depends on the ingredients used to make them. Just because a product is widely advertised and popular doesn’t mean its ingredients will be suitable for your skin, especially for those with sensitive skin. Without sufficient knowledge and the right information, it’s easy to end up purchasing cosmetics that are ineffective or even cause irritation, or worse, skin cancer.

For these reasons, it is evident that checking the ingredients in cosmetics is incredibly important in order to make the right choice for your skin.

Most skincare products share the common goal of providing essential nutrients to the skin, helping it maintain vitality or recover from damage, and enhancing a healthy complexion. Here are some key ingredients commonly found in skin-beneficial cosmetics:

• Antioxidants: These are oxidation-fighting agents that prevent harmful oxidative substances and help combat aging. Extracted from blueberries, grapes, dark leafy vegetables, and fish, they are known for their skin-protecting properties.
• Collagen: A protein found in connective tissue, collagen contributes to skin firmness and elasticity. As we age, collagen levels decline, so skincare products enriched with collagen help restore this lost component, keeping the skin youthful and plump.
• Hyaluronic Acid (HA): Primarily known for its moisturizing properties, HA prevents water loss from the skin. It is commonly found in moisturizers and serums.
• Niacinamide: This Vitamin B3 derivative improves skin elasticity and soothes irritated or red skin effectively.
• Vitamin C: A powerful antioxidant, Vitamin C is known for brightening skin tone and protecting against pigmentation, as well as preventing premature aging.
• Chamomile: Derived from Roman chamomile, this ingredient possesses anti-inflammatory, antiseptic, and antibacterial properties, making it ideal for sensitive skin or those with eczema, as it helps calm the skin.
• Vitamin E: A potent antioxidant that prevents collagen breakdown and other early aging signs such as wrinkles and dryness.
• Glycerin: A natural humectant that draws moisture into the skin, glycerin helps keep the skin soft and prevents discoloration while maintaining hydration.
• AHA: A chemical exfoliant sourced from fruits, milk, sugar, and plants. Glycolic acid (from sugarcane) and lactic acid (from milk) are prominent examples.
• BHA: A chemical exfoliant that helps remove blackheads, tighten pores, and soothe the skin. BHA is recommended for sensitive skin and gentle exfoliation. Beginners should start with lower concentrations and gradually increase.
• Retinol: A high-dose Vitamin A derivative, retinol stimulates skin cell turnover, boosting hyaluronic acid and collagen production. It's an effective treatment for acne, smoothing skin, and reducing hyperpigmentation.
• Differin: A high-dose Vitamin A derivative used for treating acne. It is incorporated into creams, moisturizers, and hair care products.
• Zinc Oxide: Commonly used in sunscreens, this ingredient provides UV protection and is suitable for sensitive skin types.

In addition to the commonly listed ingredients, there are many other skin-friendly components such as aqua, calendula, arbutin, aloe vera, acal berry, geranium, and more. You can explore their benefits through trusted websites like Google.

The safety of a cosmetic product largely depends on the safety of each ingredient used in its formulation. Many chemicals in various cosmetic products have been scrutinized for their harmful effects on the skin and overall health. Some cosmetic products in the market may still contain banned ingredients in certain countries or exceed the allowable limit of certain substances.

Below are some harmful ingredients in cosmetics that can damage your skin, and you should be aware of:

• Paraben: This artificial chemical is commonly used in small amounts as a preservative in cosmetics. Experts suggest that frequent exposure to parabens can increase the risk of breast cancer in women and decrease sperm count in men. However, the harm depends on an individual’s skin condition, as well as the dosage and type of paraben used. Common parabens include methylparaben, propylparaben, and butylparaben.

• Sulfate: A surfactant used for cleaning, thickening, and emulsifying, sulfates create foam, helping ingredients penetrate deeply into the skin while cleaning. Sulfates strip away valuable moisture and the skin's protective barrier, making it more prone to irritation. Popular sulfates include sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).

• Phenoxyethanol: Used as a preservative and antibacterial agent in cosmetics and perfumes, phenoxyethanol is harmful to health when ingested, inhaled, or absorbed through the skin. It can affect the brain and central nervous system, causing irritation to the skin and eyes. This ingredient is particularly dangerous for breastfeeding women and infants.

• Silicone: A group of synthetic polymers mainly consisting of silicon, silicone is a common ingredient in skincare, makeup, sunscreens, and haircare products. It smooths and locks in moisture while adding a shiny finish to skin and hair. However, silicone is difficult to remove and may clog pores, leading to breakouts. It can also dry out the skin and reduce the efficacy of other ingredients.

• Alcohol: Found in some perfumes, haircare products, gels, sprays, foams, acne treatments, dandruff remedies, and deodorants, alcohol can dry out, irritate, and inflame the skin by disrupting its protective layers. This leads to increased bacterial growth, exacerbating acne and inflammation. Harmful alcohols include methanol, isopropyl alcohol, propanol, and benzyl alcohol.

Additionally, there are other ingredients like Mineral oil, unsaturated oils (PUFAs), and synthetic fragrances that may pose risks to skin health.
