Surprisingly, there are a significant number of differences between real rose and synthetic rose scents. For starters, real roses contain natural compounds that trigger certain reactions in the brain associated with pleasure and relaxation. Synthetic roses, on the other hand, contain artificial fragrances that lack these same compounds and can even be potentially harmful to humans. Real rose scents also tend to linger longer in the air than their synthetic counterparts. This is because the natural compounds found in real roses are heavier and more potent than those found in artificial fragrances. So while you may not think twice about buying a synthetic rose scent, it's important to consider all of these differences before making your purchase!
