Dolly Parton, the 73-year-old country music legend (and sweetest thang that side of the pond), just told the New York Times her best travel skin care tip when on the road: sleeping in your make-up.

“I clean my face in the mornings. You never know if you’re going to wreck the bus, you never know if you’re going to be somewhere in a hotel and there’s going to be a fire. So I leave my make-up on at night and clean my face in the morning.”

You do you Dolly (there’s nobody who pulls off the frosted look better), but this token of knowledge isn’t the best she’s dished out. We know washing your face at night is key for a clear complexion. Crusty concealer and foundation left on too long will clog pores by trapping pollutants, chemicals, and sweat under the surface of your make-up. This speeds up the ageing process and generally makes for less than lustrous appearance when waking up in the morning.  

Furthermore, a study published in the American Academy of Ophthalmology last year, warned of a 50-year-old woman who suffered extreme eyesight damage due to over 25 years of improperly removing her eye make-up. After complaining about chronic sore and itchy eyes, doctors found the woman had developed concretions (solid masses formed by the accumulation of material) under her lids, a result of mascara leaking into her eye over time while sleeping at night. The build-up ended up eroding her conjunctival surface, which would have led to blindness if it had gone on for any longer.

Dolly, you might want to pick up some BioDerma on your way home tonight.
