You use the wrong water temperature
Water that’s too hot will dry your skin, while cold water won’t let your pores open, says Michele Green, MD, a New York-based cosmetic dermatologist. “Tepid water is the best water temperature,” she says. “Not too hot and not too cold.” Make sure you never, ever do these things to your skin.
You wash too often
People with dry skin might only need to cleanse once a day, and even those with more oily skin should wash twice a day at max. Any more than that could dry out your skin, making it produce even more oil to compensate, says Mona Gohara, MD, associate clinical professor at Yale’s department of dermatology. If you do wash just once, make it at night rather than in the morning. “You wash off the day’s grime and pollutants that accumulate during the day,” she says. “Not only does sun give aging, but pollutants do as well.” These are the morning skin-care routines and the nighttime skin-care routines of people with great skin.
You exfoliate too often
An exfoliating cleanser or device can slough away dead skin cells and leave the skin glowing, says Ivy Lee, MD, a dermatologist based in Pasadena, California. But daily exfoliation can lead to dryness and flakiness. “That squeaky clean feeling will lead to irritation,” she says. Limit exfoliation to just once a week. Exfoliating too much is just one of many reasons your skin hates you.
You use a dirty washcloth
Using a clean, soft washcloth is effective for cleaning your face, but unless you use a new one every day, you should probably stick with using your hands to scrub, Dr. Green says. Ideally, you should change the towel you use to dry your face every couple of days to keep bacteria at bay, Dr. Gohara says. “That’s hard for a lot of people, but it’s important to switch it out,” she says. “Moistness can accumulate bacteria.”

Your washcloth isn’t soft enough
A soft washcloth can be a good way to apply cleanser, but an overly abrasive one will be tough on your skin, Dr. Lee says. “Any one where you can feel the fibers is too rough,” she says. Don't miss these secrets your skin is trying to tell you.
You use facial wipes
Face wipes are better than nothing in a pinch, but you shouldn’t rely on them for your normal face-wash routine, Dr. Green says. “They don’t clean the skin and they have chemicals,” she says. Stash some wipes in your gym bag, but give your face a full wash with cleanser and water when you can.
You use the wrong products
Foaming washes work well for oily skin, while a more hydrating cleanser is better for dry skin, Dr. Gohara says. Those with oily skin can benefit from alpha-hydroxy acids or salicylic acids, but those ingredients can be too harsh on people without oily skin, Dr. Green says. “If you have delicate skin, you don’t want something irritating. If you’re acne-prone, a mild wash will only work if you use an astringent later,” she says. “They’re not bad products, they’re just for the wrong kind of skin.” These are beauty products dermatologists wish you would stop using.
You use a soap-based product
Never substitute a soap-based product for a non-soap cleanser. “Soap-based products strip the skin of natural oils and leave skin irritated, dry, and more likely to be inflamed,” Dr. Gohara says. “Non-soap cleansers hydrate the skin and replenish the skin barrier, so the skin is much more healthy.” You don’t have to nix any bar cleanser—Dove, for instance, is a non-soap cleanser—but read the label before using a product that looks like soap.

You rub in your cleanser wrong
For the most effective wash, rub in your cleanser using circles that go outward to stimulate blood flow and encourage your lymph to carry waste from the tissues. “It’s like a little massage,” Dr. Gohara says. “Increasing blood flow plumps up skin and primes it to sit in an upward position instead of sagging.”
You rub too vigorously
You don’t need to scrub aggressively to get rid of impurities on your skin—gently rubbing it in will do the trick without being too rough on your skin. “You don’t want to scrub it off—that’s a myth,” Dr. Green says. “With the right cleanser, you shouldn’t have to scrub hard.”
You rub your face dry
Rubbing a towel against your face will remove the lipids, proteins, and fatty acids that protect your skin from irritation, Dr. Gohara says. “It’s better to pay dry to keep that barrier intact,” she says.
You wait to moisturize
The best time to apply creams and serums is right after you’re done washing your face, so don’t wait to put them on. “Your face is the cleanest it’ll be, and you’re locking in the hydration from the water,” Dr. Gohara says. The exception? Acne products. “Acne medications can be irritating when applied on wet skin,” Lee says. “Wait until it’s dry, because you don’t want to absorb as much of the acne medication right away.” You can also try these home remedies for acne.

You let products build up
If you don’t adequately scrub off face products or makeup, or you don’t rinse your cleanser off thoroughly, your skin could get irritated and break out, Dr. Lee says. “If you’re using a foaming cleanser, rub long enough to get foam to cover and lather throughout your face,” she says. “If it’s a cream, rub enough to spread a thin layer over your whole face.” Next, read about the surprising signs of disease that your skin can reveal.
