What are the precautions using perfumes?

When using perfumes, it's important to apply them on clean, dry skin to enhance longevity and avoid skin irritation. Always perform a patch test on a small area to check for allergic reactions, especially if you have sensitive skin. Additionally, store perfumes away from direct sunlight and heat to maintain their quality, and avoid over-spraying to prevent overwhelming others with the scent. Lastly, be mindful of the environment, as some workplaces or public spaces may have fragrance-free policies.
