Is ‘Old Person Smell’ Real? Here’s What You Need to Know

WORDS LIM TECK CHOON

FEATURED EXPERT DR CH’NG CHIN CHWEN Consultant Dermatologist Subang Jaya Medical Centre

Ever noticed, or sniffed, a distinct scent associated with older adults?

The scent is described as a musky odour, and it’s not necessarily unpleasant—just noticeable in some older persons.

Commonly referred to as old person smell, this phenomenon is not a myth. It’s a natural part of ageing.

“Our body chemistry changes as we age,” Dr Ch’ng says, explaining the reason for the phenomenon.

WHAT CAUSES THE SCENT?

Dr Ch’ng explains that the scent is primarily caused by a compound called 2-nonenal, which forms when skin oils or sebum under a process called oxidization.

This compound is not soluble in water, so it is not easily washed off while bathing. Because of this, it can linger on the skin and clothes.

Other possible reasons for the scent include:

• Slower skin renewal, which causes build-up of dead skin cells.
• Change in sweat glands and the activities of bacteria on the skin.
• Certain medications may alter our body’s metabolic processes, which in turn affect the body odour.
• Though the scent itself isn’t linked to serious health issues, underlying conditions like kidney or liver disease can intensify it, so it’s essential to rule these out.

CERTAIN ASPECTS OF ONE’S LIFESTYLE THAT CAN AMPLIFY THE SMELL

These include:

• Habits such as smoking, poor hygiene, or even over-cleansing the skin. Wearing clothes made from synthetic fabrics can also be a contributing factor.
• A diet rich in processed foods, alcohol, and sugars can amplify the scent, while antioxidant-rich foods may help reduce the scent.
• Poor ventilation and synthetic fabrics can trap odours and intensify them.

The scent can also vary based on gender and ethnicity.

IS OLD PERSON SMELL HARMFUL TO THE HEALTH?

Dr Ch’ng points out that there is no direct health implications associated with the production of 2-nonenal or other changes in body odour as we age.

However, she says that it can impact one’s emotional well-being.

“It may give rise to negative self-perception, as the scent is a constant reminder of one’s ageing,” Dr Ch’ng elaborates. “It can cause one to feel shame and embarrassment in social situations even if others don’t explicitly mention it.”

Because of this, one may fear judgement from others, and this could strain relationships and/or lead to isolation and loneliness.

MANAGING ‘OLD PERSON SMELL’

Dr Ch’ng reveals that it is not possible to eliminate the scent permanently.

However, there are steps that can be taken to help reduce or neutralize the scent.

Skincare Tips

• Use mild exfoliants to remove dead skin cells.
• Moisturize regularly to maintain healthy skin.

Diet and Lifestyle

• Eat a balanced diet rich in antioxidants (such as berries, leafy greens, etc).
• Limit processed foods, sugar, and alcohol.
• Stay active and manage stress effectively.

Other Tips

• Opt for clothes made from natural, breathable fabrics.
• Keep living spaces well-ventilated.

ADVICE FOR CAREGIVERS

• If the older person’s scent is troublesome or unpleasant, approach the conversation with empathy.
• Choose the right time—when it is calm and not rushed—and have the conversation in a private environment to avoid embarrassing the older person.
• It can also be helpful to discuss the topic in a doctor’s clinic, so that the conversation is neutral and has a medical context.
• Try to normalize the issue and focus on self-care. Give the older person a sense of control over the situation by letting them choose their skincare routines and products.
• Show them respect by reinforcing their worth. For example, you can tell them: “You have always been so thoughtful and look good, this is one small thing that we can tweak to keep that going.”

LET SCIENCE DISPEL THE TABOO

The body having a certain distinct scent isn’t necessarily a bad thing—it’s biological.

For example, babies have that certain scent that is appealing to their mothers, which helps to strengthen mother-infant bonding.

Some experts believe that the older person smell helps to evoke a sense of nostalgia about the past in younger people.

Therefore, an older person’s scent is definitely not something to be ashamed about!

By understanding the science behind “old person smell” and taking proactive steps, it’s possible to manage this natural part of ageing with grace and confidence.
