There is a right way to do it and if you are not doing that way, you might be damaging your skin. Why? Firstl of all, what are most perfumes made of? If you said alcohol you are correct. So, imagine spraying alcohol on your skin and then getting sun exposure. The result, as you can imagine, can be sun damage. So, what is the solution? Well, if you intend to spend time outdoors but still want to smell as fresh as a rose, it is recommendable something alcohol free. Some brands, like La Prarie offer fragrandes alcohol free. But if your favourite fragrance doesn't give your an alcohol free option, you can spray on your clothes instead.
For the occasions when you are indoors or at night, the areas that you should apply your perfume are the ones that are called the pulse areas, or like Chanel said;
Where you want to be kissed - pulses, neck, inner elbows and chest.
Wanna know another great area to apply your favourite scent? The back of the knee. Just try and let me know the results. These warm points on the body will keep your scent emanating throughout the day as it reacts to your body heat and the scent lingers longer this way, too.
You may also consider the intensity of your perfume and how much of it you are going to spray. There are mainly 3 types of fragrance intensities: eau de toilette, being the least intense, eau de perfume, mediun intensity and the perfume, which is very rare and quite intense. I like to spritz a cloud of the fragrance and walk into it, this way, not only my clothes get the right amount of it but also my hair also gets nicely scented. All that right out of the shower when your pores are still open to receive the scent and make it last even longer.
So now tell me, how do you apply your perfume?
