Whenever it gets hot, my feet get smelly. I work in an office and have to wear socks and shoes six days in the week. Why does this happen? Tapan D, Kolkata

This happens due to bacterial decomposition of perspiration as your feet are enclosed in socks and shoes all day. As there is no option but for you to wear socks and shoes, dab some talcum powder on your feet when you have dried them after a bath. Make sure not to wear the same pair of shoes two days in a row and change your socks daily. Wear cotton socks rather than synthetic ones. Bathe twice a day, especially in the hot weather, and wash your feet well with a mild soap.

I am a 21-year-old girl with very oily skin and acne. I find that whenever I go out in the sun, especially on these hot days, my skin gets very oily and the acne increases. Why does this happen and what should I do to make it better?Rani, Dum Dum

When it is very hot and sunny and you are out, the production of sebum increases. This oil combines with dirt and sweat and blocks the pores, which in turn aggravate the acne. Make sure you cleanse your face at least twice a day with a face wash and then dab on an astringent. An astringent contains alcohol and will help to decrease the oiliness on the skin.

I am being told that gold and platinum are good for my skin, so I have regular facials containing these metals. What exactly do they do for the skin? Rita Das, Kolkata

These ingredients have been used in Ayurvedic products for hundreds of years and have been found to be beneficial for the skin. Platinum recharges the skin and strengthens the elastic and collagen, which forms the supportive tissue that keeps your skin firm.

Gold is good for a dull and dry skin and helps to delay ageing. It is also anti-bacterial and transports oxygen directly into the skin, which in turn increases cellular functions that keep the skin in a healthy condition.

I have long working hours and when I come home I have body odour and my skin feels itchy. What should I do for this?

There are a few things that are worse than body odour. It tends to build up whenever you sweat and wear fitting clothes, especially those made of synthetic fibres. These trap body moisture and prevent evaporation. The moisture forms bacteria very quickly, which is what smells. The best way to cleanse yourself is with soap. So have a bath as soon as you get home. Add some neem leaves to your bath water. There are a variety of soaps and cleansers available today so choose what is best for your skin type – this could be done by trial and error.
