A few months ago I started noticing that many of my clients had pigmentation and blotchy patches on their necks. At first, I was perplexed by this problem, specifically because the spots all tended to be on the same spot on the side of the neck. Then one day the cause hit me: perfume.
The fragrance, alcohol and chemicals in perfume irritates the sensitive skin on your neck and makes it more sensitive to the sun, leading to pigmentation and sun damage over time.
If you wear perfume, it’s best to spray it on your clothing so that the chemicals don’t get on your skin. Most people don’t know this, but putting chemicals on your skin can be far worse than ingesting them. This is because when chemicals are delivered into your blood stream via your skin, it bypasses your stomach’s built-in protective filtration process (enzymes and salvia), so you have decreased protection against the toxins. The lesson: always use safe, natural and toxin free products on your skin!

Does this report of using harsh perfume on the skin have any clinical backup?
I’m asking since this is the first time I’ve read of such a cause.
Also, I’ve read a few fashion magazines claiming it is best to apply perfume behind the ears, since this is where your pulse points are.
