Mascara is a cosmetic product that enhances the appearance of the eyes by thickening, lengthening, and darkening the eyelashes. It is usually applied with a brush and contains special ingredients that apply the product where it is needed in a precise and controlled manner. The safety of mascaras is established by selecting ingredients that are safe and suitable for this purpose, and they are assessed for their potential to cause skin irritation or allergic reactions.
Here are some positive and negative aspects of mascara ingredients:
Positive:
- Carbon black or iron oxide pigment: These pigments are used to darken lashes.
- Polymers: These form a film that coats lashes.
- Emollients, like isododecane, and silicones, like cyclopentasiloxane: These are included in waterproof mascaras to make them water-resistant.
- Jojoba esters: These are used in some mascaras to condition lashes.
Negative:
- Parabens: These are used as preservatives in many beauty products, including mascara, but have been linked to endocrine disruption, reproductive and neurological toxicity, and skin irritation.
- Formaldehyde: This is a known carcinogen and is often used as a preservative in mascara.
- Thimerosal: This is a mercury-based element that can cause conjunctivitis and eyelid dermatitis.
- Retinyl acetate: This is a known reproductive toxicant and is used in some mascaras as a moisturizing ingredient.
- Allergens: Some ingredients, such as propylene glycol, can be toxic and cause allergic reactions.
It is important to note that the FDA does not review or approve most beauty products or ingredients before they hit the market, and their safety standards are not as high as some consumers would like. Therefore, it is up to the consumer to know what to look for and what to avoid when selecting a mascara.
