Eye Makeup Hygiene: How to Use Mascara, Liner, and Tools More Safely

Is your mascara still okay to use, and can you share an eyeliner pencil with a friend? Eye makeup sits close to a sensitive area, so a few everyday habits matter more than a complicated routine. The short version: use only products labeled for the eye area, keep them and their tools personal and clean, apply makeup while you are still, and stop if irritation starts.

Quick answer: Wash your hands, check that the product is meant for eyes, keep it to yourself, and use clean tools. Follow the label. The FDA says to discard mascara three months after purchase, throw away dried mascara instead of trying to revive it, and avoid eye makeup when you have an eye infection or inflamed skin around the eye.

Start with a product made for the eye area

Before opening mascara, liner, or another eye product, read the label and make sure it is intended for use near the eyes. A product that is fine for lips or cheeks is not automatically suitable for eyes: the FDA specifically advises against using lip liner as eye liner, because the color additives or contamination risks may differ, as the FDA explains in its eye cosmetic safety guidance. If the label does not clearly say the product is for the eye area, leave it off your eyes.

Keep eye makeup personal. Do not share or swap mascara, liner, or applicators, even with someone you know. At a store, avoid shared testers where possible. If you choose to sample a product, ask for a new, single-use applicator rather than using the shared wand or pencil. The FDA recommends this approach because shared eye-makeup testers can be more likely to become contaminated. These hygiene steps are not a guarantee that any cosmetic is sterile or risk-free; see the FDA’s eye cosmetic safety guidance.

Start with clean hands and clean instruments. The FDA advises washing hands before applying eye cosmetics and making sure instruments placed near the eye are clean, as described in its eye-cosmetic safety checklist. Follow the product and tool makers’ care directions; do not assume that every tool should be cleaned in the same way. Close containers when you finish and keep them away from excessive heat, such as a hot car.

Apply eye makeup from a still, clean setup

Choose a stable place where you can sit or stand without rushing. Keep a mirror steady and put the products you plan to use within easy reach before you begin. The useful safety check is simple: if you have to balance, reach awkwardly, or move while a wand or pencil is near your eye, pause and reset your setup.

Do not apply or remove eye makeup in a moving vehicle, even as a passenger. A bump or sudden stop can make an applicator strike the eye. When placing or removing makeup, move carefully around the eye rather than pressing a tool against the eyeball or another sensitive area. The FDA warns that an applicator scratch can lead to a serious infection; its eye makeup guidance explains why applicators should be kept away from the eyeball.

Use each product as its label directs. Do not add water or saliva to mascara that has dried out; the FDA says either can introduce germs, and water can dilute the preservative; see its mascara safety advice. If a brush, curler, or other tool looks dirty, set it aside until you can clean it according to its instructions. A clean surface and a still setup make the routine easier to control, but they do not replace product directions or remove every risk.

Stop using a product when irritation or infection is a concern

If an eye cosmetic causes irritation, stop using it. The FDA advises seeking medical advice if the irritation persists, according to its eye-cosmetic safety checklist. Do not try to cover discomfort by adding more makeup or switching products around the eye. This guide cannot identify the cause of redness, itching, swelling, pain, or a change in vision; a health professional can help assess symptoms, especially if they are severe, worsening, or affecting vision.

Avoid eye cosmetics when you have an eye infection or inflamed skin around the eye, and wait until the area has healed. The FDA says to discard eye cosmetics you were using when the infection began because they may have become contaminated; see its guidance for eye cosmetics. If you are unsure whether a product is safe to use again, ask a health professional rather than testing it on the eye area.

Keep track of when you buy mascara. FDA’s eye-cosmetic safety checklist says to discard mascara three months after purchase and to throw away dried-up mascara sooner. The FDA’s cosmetic shelf-life guidance also notes that manufacturers commonly recommend discarding mascara within two to four months; follow the product’s own directions if they call for an earlier replacement. The same FDA shelf-life guidance explains that U.S. cosmetics generally are not required to carry a specific shelf-life or expiration date, so a purchase or opening note can help you remember. Do not add liquid to stretch a tube’s life.

Your quick eye-makeup check

• The label says the product is intended for the eye area.
• Your hands, product container, and tools are clean; the product is not shared.
• You are still, settled, and able to see what you are doing.
• You know when you bought the mascara, and it is not dried out.
• If irritation begins, you stop; if it persists, you seek medical advice.

Eye makeup is optional. If you choose to use mascara or liner, a label check, clean personal tools, and a still setup are useful places to begin. For the specific safety details, see the U.S. FDA’s guidance on eye cosmetic safety, cosmetic shelf life, and using cosmetics safely.
