We’ve been told it our whole lives: a daily shower is the foundation of good hygiene. But what if this deeply ingrained habit becomes less beneficial than we think as the years go by? After 70, our skin changes profoundly, and what we consider a healthy reflex could, according to several specialists, do more harm than good. Enough to make us question some long-held beliefs… with a healthy dose of self-awareness.
Skin that changes, needs that evolve.
As we age, our skin changes: it becomes thinner, drier, and more sensitive. The sebaceous glands slow down their production of natural oils, and the skin’s protective barrier gradually weakens. The result? Skin that is less equipped to defend itself and retain its natural moisture.
Daily showers, especially with hot water and soap, accelerate this process. They strip away the skin’s protective oils, leading to dryness, itching, and minor irritations. These micro-lesions, often invisible, can become entry points for infections. After 70, softness is no longer a luxury, it’s a necessity.
Maintaining a healthy bacterial balance in the skin is a valuable ally.
Our skin is home to billions of beneficial bacteria that form a veritable natural shield. Washing too frequently—especially with antibacterial or heavily perfumed soaps—disrupts this delicate balance. Paradoxically, skin that is “too clean” becomes more vulnerable to redness, fungal infections, and inflammation.
Doctors are now talking about “over-hygiene”. The goal is not to abandon cleanliness, but to approach it differently: favoring gentle, unscented products, and preserving the skin microbiome that protects us daily.
Two to three showers per week: the surprising recommendation
Most dermatologists and geriatricians agree on this point: after 65-70 years, two to three showers per week are more than enough, except in special cases (intense physical activity, specific medical problem).
On other days? A targeted wash is perfectly sufficient: face, hands, underarms, and a damp washcloth to refresh. Simple, effective, and much kinder to the skin. And as for soap, there’s no need to use it everywhere: underarms, groin, and feet deserve daily attention, but the rest of the body washes very well with plain water.
