Washing 3 times a day	When the skin of 25 healthy volunteers was washed with an automated device 3 times a day for 4 days, water loss rose and stratum corneum hydration fell with all 5 workplace (occupational) skin cleansers (not a facial cleanser study)	2014 PMID 24588368 · B

When you break out, how often do you wash, and with what?

The KDCA, Korea’s public health agency, advises washing twice a day, morning and night, with a gentle, low-irritation cleanser. Even in a week when you break out, stick to two washes instead of adding more, and just record which cleanser you used.

What should you do when you feel like washing a third time?

If you sweated in gym class or during a workout on the way home from work, it is fine to log one more wash that day. If it is only shine bothering you and you have not sweated, press it off with blotting paper and move on, because in a 2014 trial (PMID 24588368) that washed the skin of 25 healthy volunteers with an automated device 3 times a day, all 5 workplace (occupational) skin cleansers increased water loss (not a facial cleanser study).

Is rinsing in the shower okay, and how many rinses?

We found no institutional guidance on shower rinsing or how many times to rinse. Cup lukewarm water in your hands and rinse until no lather is left, then note how many rinses it took and look at that alongside tightness.

If tightness often lasts more than 30 minutes, the number of washes or the cleanser may be too much; if on two-wash days shine only shows up late in the afternoon, read that as a sign your current routine is enough. In a 2006 trial where 25 people washed their hands 4 times a day for 2 weeks (PMID 16476166), hydration on the side that used cream did not change much, so on days with long-lasting tightness, also note whether you moisturized after washing.

When should you see a dermatologist about washing and irritation?

• If stinging or redness lasts all week even after you cut back to twice a day, see a dermatologist.
• If breakouts keep increasing no matter how often you wash, take your log to a dermatology visit.
• If itching or a bumpy rash appears after you switch cleansers, stop using it and get it checked.

Evidence behind this washing log

• In a 2014 trial that washed the skin of 25 healthy volunteers with an automated device 3 times a day for 4 days (PMID 24588368), all 5 workplace (occupational) reference skin cleansers raised transepidermal water loss and lowered stratum corneum hydration (not a facial cleanser study).
• In a 2006 crossover trial where 25 people washed their hands 4 times a day for 2 weeks (PMID 16476166), hydration on the wash-only side fell from 79 to 65.5 by day 14.
• The KDCA says washing twice a day is enough and that washing too often can make acne worse.
