Discolouration may have several causes and does not on its own identify whether a cosmetic is safe or unsafe. The accompanying smell, texture and storage history can matter.

A dark bottle can make colour changes less visible but does not remove the need for appropriate product stability work.

If a purchased fragrance changes significantly or seems abnormal, stop using it and ask the seller for guidance rather than attempting to fix it yourself.

Understand the practical considerations behind a finished fragrance, including stability, packaging, variation and responsible product information. These are general fragrance perspectives, not claims about the ingredients or readiness of any XASIS visual concept. Always refer to actual finished-product details for purchase and use.
