On average, perfumes can last 3-5 years when stored properly. Over time, a fragrance may change due to oxidation or exposure to light. If you notice a significant change in color or scent, it may be time to replace the bottle.

Perfumes are composed of three layers of fragrance called notes. The top notes are the initial scents you smell when you first apply the perfume, usually fresh or citrusy. The middle notes, also called heart notes, emerge after the top notes fade and make up the main body of the fragrance. Finally, the base notes appear as the perfume dries down, giving the fragrance its lasting depth and richness.

Choosing the right fragrance depends on your personal preferences, mood, and the occasion. Light, citrusy, or floral scents are great for daytime and summer, while deeper, woody, or oriental fragrances work well for evening and colder seasons. You can sample different perfumes in-store or purchase smaller travel sizes to try at home.

Yes, but you should choose perfumes carefully. Opt for fragrance-free or hypoallergenic products, and always perform a patch test before applying to larger areas. You can also apply perfume to your clothing instead of directly on your skin to minimize irritation.
