Ask Yardley



  • Q: Why does a deodorant’s smell disappear after a short while but a cologne’s pleasant smell lasts the entire day?
    A: Generally a cologne is more concentrated than a deodorant, and will be more substantive.
  • Q: Why are there two kinds of deodorants – spray and roll on – and which one is best?
    A: Roll-on helps prevent sweating and bad odours, whereas a deodorant spray has a minimal concentrate of fragrance that makes you smell good, but not necessarily prevent perspiration, unless it is an anti-perspirant spray.
  • Q: Why do some roll-ons leave a white residue on skin while others don’t?
    A: The active ingredient in roll-ons which makes them effective could leave a white residue or layer on the skin. Some formulations contain less actives or contain different actives that are less prone to appear white.
  • Q: Why do perfumes contain alcohol?
    A: The alcohol evaporates to ensure that you are left with the concentrate fragrance on your skin to last.
  • Q: What is the difference between an Eau de Toilette and Eau de Perfume?
    A: The fragrance level is more concentrated in an Eau de Parfum than in an Eau de Toilette, which is less concentrated.

  • Q: Will a roll-on deodorant keep me dry all day?
    A: It all depends on the claims made. You need to look out for a 24 hour protection claim that will prevent from sweating that causes bad odours.
  • Q: How do I know which perfumes suit me?
    A: Lifestyle and diet affect the reaction of fragrances on the skin. Some of the essential oils might agree to your skin more than others and may be absorbed while others may not. So there is no perfect recipe other than trial, or knowing which olfactory family works for you.
