Why using tap water to wash your face can do ‘more harm than good’

“Tap water often contains chlorine, fluoride, and other chemicals meant for disinfection, but these can strip the skin of its natural oils, leading to dryness, irritation, and redness. For individuals with acne-prone skin, these chemicals may exacerbate inflammation and compromise the skin’s barrier, making it more susceptible to breakouts and bacterial infections.”

The impurities in the tap water mainly cause these bacterial infections and breakouts.

So, how do impurities, chemicals, or hard minerals in tap water affect skin health over time?

Over time, Dr Arora added, impurities and hard minerals like calcium and magnesium in tap water can accumulate on the skin, causing dullness and rough texture. “Hard water also interferes with cleansers, preventing them from rinsing off thoroughly and leaving residue that clogs pores.”

“The pH imbalance created by these minerals can damage the skin barrier, leading to premature ageing, increased sensitivity, and even conditions like eczema or dermatitis. Continuous exposure can cause the skin to feel tight, itchy, and dehydrated, despite the use of moisturisers.”

Dr Arora further stressed that different skin types respond differently.

And what are these skin types?

Mostly, individuals with dry, sensitive, or acne-prone skin are more likely to experience irritation from tap water, the skin expert added. “Those with existing skin conditions such as rosacea, eczema, or psoriasis are particularly vulnerable because their skin barrier is already compromised. Oily skin types may initially tolerate tap water better, but over time, even they can experience imbalances and breakouts due to disrupted pH levels and clogged pores.”

However, individuals with such skin types can try alternative daily face-cleansing products recommended by their doctor.

The alternatives can be

Dr Arora further suggested, “Micellar water, thermal spring water, or filtered water are gentler alternatives for cleansing the face. Micellar water effectively removes dirt and makeup without disturbing the skin’s natural barrier.”

Even thermal spring water is rich in minerals that soothe inflammation and restore balance, he added. “Using a water purifier or softener can also reduce hardness and impurities in tap water. For optimal results, always follow cleansing with a pH-balanced toner and a suitable moisturiser to maintain healthy, hydrated skin.”
