In a traditional fragrance, the top note oils - responsible for the fresh initial scent - quickly evaporate after spraying on skin. Most users don't like losing this first impression so quickly. Fortunately, Time Release Technology traps the top note oils in the perfume, steadily releasing them over time. This allows the fragrance to smell fresher for much longer, as if it had been freshly applied. Naturally, the length of time depends on the individual's skin chemistry, but it can last from the morning until the evening.
