The basic handling rule
Keep the shelf calm and the product traceable.
Store perfume and care products according to the product label, away from unnecessary heat and direct sunlight. Keep caps, pumps, and closures properly fitted after use. A bathroom can be humid and warm; that makes it worth reading the label rather than assuming every bottle belongs beside the sink.
Keep the original container where possible. It carries the product name and the information needed for a later question. Do not decant a face cream, oil, mist, or eau de parfum into an unmarked bottle and then expect a useful review of its condition.
Use clean, dry hands when the format asks for it. Do not add water, another oil, fragrance, or household material to a cosmetic product. A new mixture is no longer something the catalogue can describe from its original format.
Protect the bottle.
An eau de parfum or eau de toilette is a fragrance format, not a room spray or a skin treatment. Keep the cap or spray closure fitted, avoid leaving it in a hot vehicle, and do not use the bottle if the container is cracked or the closure has failed. Cedar stays dry here; orange keeps the opening bright.
Follow the format.
Body wash, hand balm, body oil, bath soak, and lotion are different formats. Use the amount and contact instructions on the product label. Do not assume that a rich oil should be used where a cleanser belongs, or that a body care gift set is a treatment plan. The catalogue describes use context, not a promised result.
Keep face care simple.
Face care products can include cleanser, mist, cream, oil, or a rinse-off mask. Start with the label and use only as directed. Avoid the eye area unless the product instructions specifically address it. Stop if the product causes discomfort and seek qualified advice when the concern does not settle.
Mind the contact.
Shampoo, conditioner, scalp oil, and hair mist are not interchangeable. Keep spray and oil formats away from eyes, use them as labelled, and keep bottles closed between uses. Hair care products are cosmetic formats in this catalogue. They are not presented as treatment for a scalp or hair condition.
