What can I do to prevent eye infections from make up? Costly to replace it btw.

Complete removal. Many eye infections associated with makeup are from incomplete removal of mascara, eyeliner, etc. It helps to use a lid scrub or dilute baby shampoo to follow any standard makeup remover. Sterilizing eyeliner pencils and sharpeners with alcohol can also prvent recurrent infections, but the best answer is to purchase small containers of makeup and change to fresh every 90 days.
