Popularity be damned, this skincare fad needs to go. Here are 5 reasons why:
1. Coffee beans are highly susceptible to mold, rot and bacteria growth
Just like in the rainforest, coffee grinds in your scrub have a very good chance of going bad. The research available on this is extremely limited, but I first noticed it in my own formulations. Coffee grinds hold water very well, which means that when you introduce water to a scrub with coffee in it, the water will initiate bacteria growth (bacteria needs only water, oxygen and nutrients to grow, which is why you should NEVER buy an unpreserved natural beauty product that contains water). Most scrubs do not contain water in the formula, but they often become contaminated with water from our shower / bath / fingertips.
2. Coffee grounds, no matter how fine, clog your drain
Even Allure says so, beauties!! Whether you rent or own, coffee scrubs are a ridiculously expensive habit. Bat those eyelashes all you want, when the super hears that you're putting coffee grinds down the pipe, they will foot you with the plumbing bill.
"Coffee scrubs are one of the worst things you can put down your drain," says Jim Steine, the president of Atomic Plumbing in Virginia. Sorry, Pinterest enthusiasts. "Even if you use a finely-ground coffee scrub just once a week, it will eventually mix with the oils in your pipes and coagulate."
3. Coffee is going extinct
You read correctly, so ease up on that cold brew while you're at it. Due to climate change and its impact on temperature, disease and pollinators, high quality coffee could be unproductive by 2050- which is why companies such as Starbucks are acting now to protect their cash cow.
4. Harsh exfoliantes, like coffee grinds, cause skin tears
Oh youth, how invincible you are. You may be able to get away with harsh scrubs in your teens and twenties, but even that damage ads up in the long run. Abrasive exfoliants breakdown our skin barrier formation and damage tissue, which leads to deep tissue scarring and a higher susceptibility to infection and breakouts. Exfoliating is super important, just don't do it with ultra-hard or large-ground substances. I recommend sticking with ultra-fine to powder-fine grains, and to always avoid hard shells and minerals such as walnut and pumice.
5. Coffee creates water loss
Caffeine is an awesome diuretic, which means that it drains water from the body. This is a powerful tool to tackle bloating and puffy eyes, but not necessarily desirable for an all-over scrub down. For purposes of detox, hell yes, flush that water carrying toxins out of your body. On the daily however, most of us do not drink enough water as it is, so flushing it out only promotes dehydration, sagging skin, muscle cramps, nervousness and discomfort.
I hope you enjoyed this caffeinated-insight!
