Old People’s Odour

Can anyone offer advice? I am a bit desperate. It seems that I have developed the ‘old people smell’ put politely odour ... (Nonenal). It’s not a lack of soap and water or cleanliness generally ... and am embarrassed. I dread standing near anybody ... social distancing has its benefits! I am booked in to the Opticians and Hygienist soon, oh dear ☺️
