When you swipe on your favorite lipstick or blend out a new foundation, you are trusting a complex cocktail of chemicals with your skin’s health. While the beauty industry is often associated with glamour, the regulatory reality is far more utilitarian. In the United States, the U.S. Food and Drug Administration (FDA) does not require cosmetic products or ingredients—excluding color additives—to have FDA approval before they hit the shelves [1].
The burden of safety falls largely on the manufacturers and, ultimately, the consumer. This guide will teach you how to decode labels, identify prohibited substances, and verify the safety of your makeup kit.

1. Recognize Prohibited and Restricted Ingredients
Safety begins with knowing what legally should not be in your products. Although the FDA has less oversight than it does with drugs, it specifically prohibits or restricts several high-risk ingredients due to proven toxicity.
- Mercury Compounds: These are restricted to eye-area products at very low concentrations (under 65 parts per million) and only if no other safe preservative is available. Mercury is a neurotoxin that can be absorbed through the skin [2].
- Formaldehyde-Releasers: While not outright banned, ingredients like DMDM hydantoin and quaternium-15 release formaldehyde over time to prevent bacterial growth. Many consumers on Reddit’s r/SkincareAddiction community have reported contact dermatitis from these preservatives.
- Bithionol and Chloroform: These are strictly prohibited in cosmetics because they can cause skin sensitization to light or are known carcinogens [2].
When you are looking for a natural makeup look, prioritizing products with shorter, cleaner ingredient lists can reduce the risk of accidental exposure to these restricted substances.
Mercury compounds are only permitted at extremely low concentrations (under 65 ppm) when no other safe preservative is available to prevent bacterial growth. However, consumers should still be cautious as mercury is a known neurotoxin that can be absorbed through the skin.
Ingredients like DMDM hydantoin do not contain liquid formaldehyde but release it slowly over time to act as a preservative. This process can cause contact dermatitis or skin irritation for many users, particularly those with sensitive skin.
2. Check for Heavy Metal Contamination
Heavy metals like lead, arsenic, and cadmium are rarely added as ingredients; they are usually “unavoidable” contaminants from the earth or the manufacturing process.
The FDA has issued guidance to the industry recommending that lead levels in lipsticks and externally applied cosmetics stay below 10 parts per million (ppm) [3]. To ensure your products are safe:
Avoid “Kohl” or “Kajal”: Traditional eyeliners often imported from the Middle East or South Asia frequently contain high levels of lead [3].
Stick to Reputable Brands: Major manufacturers often have stricter internal quality controls for batch testing than smaller, unregulated “dupe” brands found on third-party marketplaces.
While the FDA recommends that lead levels stay below 10 parts per million (ppm) for safety, heavy metals are typically unintentional contaminants from the manufacturing process rather than added ingredients. Sticking to reputable brands helps ensure products meet these safety guidelines.
Traditional Kohl or Kajal liners imported from certain regions often contain high levels of lead as a primary component. To protect your vision and health, it is safer to use modern eyeliners from regulated manufacturers that comply with FDA safety standards.
3. Understand “Marketing Speak” vs. Regulatory Definitions
Cosmetic labels are often filled with “claims” that have no legal definition. Learning to distinguish between them is crucial for your safety.
- “Hypoallergenic”: According to the FDA’s official consumer resources, there are no federal standards or definitions governing the use of the term “hypoallergenic” [4]. A brand can claim this without proving it to a regulator.
- “Natural” vs. “Organic”: The term “natural” is not defined by the FDA or USDA in cosmetics. However, “Organic” refers specifically to the USDA’s agricultural standards for how ingredients are grown [4].
- Expiration Dates: The law does not require cosmetics to have expiration dates. Instead, look for the PAO (Period After Opening) symbol—a small open jar icon with a number followed by an “M” (e.g., 12M). This tells you how many months the product is safe to use after you first open it [4].
The term ‘hypoallergenic’ has no legal or federal definition, meaning brands can use the claim without proving it to regulators. If you have sensitive skin, it is better to perform a patch test rather than relying solely on this marketing label.
Look for the Period After Opening (PAO) symbol, which resembles a small open jar with a number and the letter ‘M’. This indicates how many months the product remains safe to use after it has been opened, regardless of when it was manufactured.
4. Evaluate Color Additives
Color additives are the one area where the FDA has strict pre-market approval power. All color additives must be approved for their specific intended use. For example, a color that is safe for your cheeks may not be safe for the area around your eyes.
Using a lip liner as an eyeliner is a common mistake that can lead to irritation or infection. Always ensure your quality cosmetics are used exactly as the label directs to maintain safety.
| Category | FDA Pre-Market Approval |
|---|---|
| Color Additives | Required (Specific use-case) |
| General Ingredients | Not Required |
| Product Safety | Manufacturer Responsibility |
Not necessarily; a color additive approved for use on cheeks or lips may not be approved for the sensitive eye area. Always check the label to ensure a product is specifically intended for the part of the face where you plan to apply it.
Color additives are the only cosmetic ingredients that require strict pre-market approval from the FDA. Each pigment must be safety-tested and approved for its specific intended use before it can be legally sold.
5. Screen for Microbial Safety
Even the “cleanest” formulation becomes dangerous if it grows mold or bacteria.
The Sniff Test: Changes in smell or color are immediate red flags. If a cream product begins to separate or smells “sour,” throw it away [4].
Preservation Matters: While many people seek “preservative-free” makeup, these products have a significantly higher risk of microbial contamination, especially if they are water-based.
Actually, preservative-free products can be more dangerous because they have a higher risk of growing harmful mold and bacteria. This is especially true for water-based products, which require preservatives to stay shelf-stable and hygienically safe.
Immediate red flags include a ‘sour’ or unusual smell, changes in color, or the product beginning to separate. If a cream or liquid foundation changes consistency or scent, it is best to dispose of it to avoid infection.
Summary of Key Takeaways
Action Plan for Consumers:
- Read Every Label: Don’t just look at the front of the box; check the back for “Red Flag” ingredients like Mercury, Bithionol, or Formaldehyde releasers.
- Verify the PAO Symbol: Write the date of opening on the bottom of the bottle with a Sharpie to track its “active” life.
- Cross-Reference Ingredients: Use the Environmental Working Group’s (EWG) Skin Deep Database to search for specific product ratings based on toxicity.
- Perform a Patch Test: Apply a small amount of any new product to your inner forearm for 24 hours to check for allergic reactions before applying it to your face.
- Wash Your Hands: The FDA emphasizes that hand hygiene is the easiest way to prevent contaminating your makeup with germs [4].
Checking your makeup safety isn’t about fear; it’s about being an informed consumer. By understanding that “hypoallergenic” is a marketing term and that lead can be an accidental contaminant, you can make smarter choices that protect your skin and health in the long run.
| Metric | Action Recommended |
|---|---|
| Red Flags | Avoid Mercury, Bithionol, and Formaldehyde-releasers |
| Expiry | Check the PAO symbol (e.g., 6M, 12M) |
| Testing | Always perform a 24-hour patch test |
| Hygiene | Wash hands before application and check for odor changes |
You can use the Environmental Working Group’s (EWG) Skin Deep Database to look up specific products and ingredients. It provides toxicity ratings and safety data to help you make more informed purchasing decisions.
Hand hygiene is critical because your fingers can easily transfer bacteria and germs into your makeup containers. Once contaminated, the product becomes a breeding ground for microbes that can cause skin breakouts or eye infections.
