Different materials evaporate and become noticeable at different rates. What you perceive is a changing balance, not three completely separate perfumes.

A seamless transition can make a composition feel polished; a dramatic shift can be part of its character. Both may be intentional.

Return to a sample after half an hour and again much later. Note what remains recognisable and what has become newly prominent.

An individual formula may not follow a textbook structure. Make space for exceptions, sample carefully and decide what you genuinely enjoy. XASIS currently presents its Signature Five as fragrance design concepts in development; final notes, formula details and availability are confirmed only for finished products.
