You may think that the more perfume you spray the longer it will last. But your over-zealous way of spraying fragrances won t help it last longer. Make-up artist Janet Fernandes shares hacks to help you get the most out of your oh-so-expensive perfumes. Don t store perfumes in damp places: Avoid storing your perfumes in the bathroom or other damp places if you want the fragrance to last longer. The humidity and heat in moist areas can break down the scent and reduce the aroma. Dry and cold places like your vanity bag can be perfect to store them.
