The eyes may be one of the easiest facial features to play around with when it comes to makeup. All it takes to add something special to your look is a perfectly lined eye or a slick or two of volumising mascara. The options for the eyes are endless, too, with eyeshadow palettes available in every shade imaginable. 

But it’s vital to keep your eye makeup products and the tools you use clean to ensure that no bacteria brews and no infections occur. Here’s what you need to know about good eye hygiene… 

Is it really necessary to clean your makeup tools?

Yes, says Dr Mamello Ntsele, a dermatologist in KwaZulu-Natal.  "It's crucial to clean makeup tools regularly to prevent bacterial buildup and contamination." This is especially true for makeup tools that are used around the eye area, as this area is delicate and prone to infection. 

Ensure you clean your makeup brushes with mild soap and water and sanitise them with a mixture of water and antibacterial soap or a special brush cleaner, says Dr Ntsele.

This thorough cleaning of tools should take place at least once a week, or more often if you use your eye makeup tools frequently.

How often should you replace your make up tools and products?

If you ever notice your brush’s bristles falling out or becoming harder, it’s time for them to be replaced. While keeping your brushes clean and cared for will help them last longer and maintain their effectiveness, there comes a time when all good brushes need to be replaced. The same goes for makeup products. 

Dr Ntsele shares her advice on how often eye makeup products need to be replaced for optimal hygiene:

- Mascara: Replace every 3-6 months to prevent bacterial growth.

- Eyeliner: Replace every 6-12 months or according to the manufacturer's guidelines.

- Eye makeup brushes: Clean regularly and replace every 1-2 years or when bristles become worn.

What are the signs of an eye infection?

Failure to thoroughly clean your eye makeup tools and to replace products within the recommended time frame could result in an eye infection. Infections are also more common when products or tools are shared between two (or more) people, so the experts advise against doing this. 

Dr Ntsele says the below signs and symptoms may indicate an eye infection:

- Redness, swelling or inflammation around the eyes

- Discharge coming from the eye

- Itching or burning around the eye area

- Blurred vision or sensitivity to light

- Crusting or flaking around the eyes

How do you prevent and treat eye infections?

Good hygiene is essential when it comes to applying eye makeup, whether you apply makeup daily or only on special occasions. 

"Always wash your hands before applying makeup to your eyes, and avoid sharing makeup or tools," advises Dr Ntsele. If you do need to share products or tools with others, ensure the applicators are thoroughly cleaned in-between uses. If you're making use of a makeup artist, ensure they too are practicing good hygiene and that they replace their products on a regular basis. 

"Avoid touching your eyes unnecessarily and remove all makeup properly before sleeping," says Dr Ntsele. Also ensure that you use skincare products, like makeup removers, eye creams and serums that are suitable for your skin type and made specifically for use around the eyes.

If you do pick up an eye infection due to poor hygiene, makeup products that are in poor condition or due to any other reason, avoid wearing makeup until the infection has been treated and has cleared completely, advises Dr Ntsele. 

"Consult a doctor if you suspect an eye infection. Treatment may involve antibiotics, antiviral medication or anti-inflammatory creams," says Dr Ntsele.
