1. Immediately Replace the Lid
One of the simplest things you can do to keep your makeup fresh is to ensure that you immediately replace the lid after using any product. This will help to prevent air from getting in and drying out your products or allowing bacteria to enter.
2. Use a Makeup Brush Cleaner Regularly
Another way to keep your makeup looking fresh is by regularly cleaning your makeup brushes with a good quality brush cleaner. This will help remove any build-up of products, bacteria or dirt which could transfer onto your skin when applying makeup and cause breakouts or irritation. Ideally, you should cleanse your brushes once a week but if you are using them daily then more frequent cleansing may be necessary.
