It may seem bizarre to think that there could possibly be wrong ways to take a bath, but according to Stacy Chimento, a board certified dermatologist of Riverchase Dermatology in Miami, there a several basic mistakes that should be avoided when taking a bath. These mistakes can cause damage to your skin, even though you may not realize it. Read the five common mistakes below and learn about the negative impact they can have on your skin.

1. The water is too hot

That super-hot bath water feels relaxing, but it’s not doing your skin any good. “Hot water can be abrasive, stripping the skin of its natural oils, which leaves it dehydrated and dull-looking,” says Dr. Chimento. “If you get the water on your face as well, this can cause acne flare-ups, breakouts, and skin irritation.”

Dr. Chimento says the ideal temperature for a bath is between 100°F to 110°F, which is warm but not uncomfortably hot. “If the water is too hot, the outer layer begins to break down, allowing the entry of bacteria and toxins and drawing out moisture,” she says.

2. You’re soaking for too long

If you’re taking hour-long baths, you might want to cut down you time… a lot. “When taking a bath, you should try to limit it to 15 minutes,” Dr. Chimento says. “Anything longer than that will begin to strip the skin of its natural oils, leading to inflammation and irritation.” Basically, when it starts to get cold, get out.

3. You’re shaving before a bath

It might not seem like there’s any harm in shaving before a bath, but it could be setting your skin up for disaster. “Shaving opens your pores and sometimes create little nicks in the skin. If you take a bath directly after, you’re allowing germs and bacteria to reach those places, too, which you don’t want,” Dr. Chimento says. Save shaving for the shower instead.

4. You’re using essential oils

Yes, essential oils make your bath smell amazing. Unfortunately, your skin might not appreciate the soothing scents. “Essential oils should never be mixed with water, as they won’t dilute,” Dr. Chimento says. “While essential oils are rich in antioxidants and antibacterial ingredients beneficial for the skin, most of them include fragrance ingredients that can significantly irritate the skin.”
