In part two of her series, Sarah Darbandi, MD discusses the role of cosmetics in Demodex and the importance of daily ocular hygiene.
Q: Is there a correlation between cosmetics and Demodex?
A: Yes. Typically what I see under the microscope is layers of dead skin, collarettes, with mascara stuck to it and eye shadow particles entrapped in the sleeves of debris on the lashes. Since some ingredients in makeup are toxic for dry eye patients who are already very sensitive, this is just one more insult to their eyelids. They typically have red, irritated eyes, and with makeup they are adding waxes and parabens that block the glands and add more inflammation.
