Know that some perfume Poisoning you
​You might think that finding out what’s in your perfume would be as easy as reading the ingredient label.
But because of laws that protect fragrance manufacturers from sharing “trade secrets,” almost every perfume sold commercially is crammed with chemicals that aren’t listed individually on the product packaging.Instead, these chemicals are simply covered by the word “fragrance” — a catchall ingredient category that really could mean anything.

Because so many ingredients included in perfume aren’t disclosed to the buyer, there are some well-founded concerns over the chemical reactions perfume can trigger in your body.
Ingredients to worry about

One study conducted by the Environmental Working Group (EWG) estimated that only 34 percent of stock ingredients often found in fragrances have been tested for toxicity.

Perfumes may include
respiratory sensitizers that trigger wheezing or asthma
hormone sensitizers that throw your endocrine system off balance
secret ingredients that are harmful to your reproductive system when they build up in your body over time
As mentioned above, most perfume manufacturers are able to avoid actually listing these toxic ingredients on their packaging. With that being said, here are some ingredient names to look out for, especially if you’re pregnant or know someone trying to get pregnant:

phthalates
styrene
Galaxolide ketone and other musk ketones
ethylene glycol
acetaldehyde
oxybenzone

Symptoms of perfume poisoning

swaying while walking or trouble with balance
slurred speech
lethargy or lack of energy
breath that smells of alcohol
nausea or vomiting
When to seek immediate help
a spiking temperature

Dose the Perfumes and the fragrances - has undesirable effects?
About 3,000 different chemicals (both synthetic and natural) can be used to make a perfume or a fragrance additive, and a product may contain from 10 to more than 300 different chemicals.
Contact dermatitis
Allergic contact dermatitis is the most common allergic response to skin allergens and typical clinical symptoms include itching, redness (erythema), swelling (oedema) and at worst blistering. The reaction normally appears where the cosmetic product was applied, but strong reactions can also trigger reactions outside the application area. Remains of the cosmetic product can also be transferred from your fingers and cause contact dermatitis in unexpected areas such as the genitals.

Allergic contact dermatitis from fragrances often occurs on the hands, in the armpits and on the face. It may be the primary cause of hand eczema, or occur as a complication of irritative or atopic dermatitis. Reactions in the armpit are often caused by the use of deodorants. If the reaction is extreme, it can spread down the arms and to other areas of the body. Eczema of the face is often caused by perfumed skin care products and after-shave products, but wet-shaving has also been proven to give an increased risk of fragrance allergy.

Irritative contact dermatitis from fragrances is believed to be a general problem but there is a lack of studies that quantify the proportion of the population with this form of contact dermatitis. The clinical symptoms of irritative and allergic contact dermatitis are very similar, and it may therefore be difficult to distinguish between these two conditions.

Contact urticaria
Symptoms of contact urticaria include itching and localised areas of swelling and redness (wheal-and-flare) where the cosmetic product was applied but also generalised urticaria (swelling anywhere on the body) and anaphylaxis. The symptoms may appear just minutes after exposure to the allergen, and usually abate relatively quickly (within a few hours). Fragrances such as cinnamal, cinnamic acid and Myroxylon pereirae have been shown to cause non-immunological contact urticaria. Other substances that have been reported to provide the same type of response include menthol, vanillin and benzaldehyde.
Photoallergy and phototoxicity
Clinical symptoms of photoallergy are mainly eczema. The symptoms appear and disappear within 2-48 hours after application of the product. Sun-exposed areas are most commonly affected but symptoms can also spread to other areas. In the 1970s many cases of allergy were observed that were caused by musk which was subsequently banned in cosmetic products. Other fragrances that may cause photoallergy include cinnamates.

Phototoxicity (non-allergic) reactions from fragrances can occur. This can cause symptoms such as redness of the skin followed by hyperpigmentation. Furanocoumarins are plant-derived fragrances that have been shown to cause such a reaction.​

6 Body Areas You Should Avoid Applying Perfume On

When it comes to your favorite fragrance, less is more.

Hair
Since hair absorbs smells naturally, it may appear to be a smart idea to spritz the fragrance into your locks at first. However, alcohol-based fragrances may be quite drying, especially if sprayed straight into your hair. Instead, Cosmopolitan recommends pouring perfume into your brushes before brushing your hair to minimize damage or lightly spritzing the ends.


Most individuals do not consider spraying straight into their hair to be harmful. It is essential to understand that hair naturally absorbs fragrances, which is not good. Alcohol-based fragrances may be extremely drying, especially when sprayed straight into the hair.

Hands
Applying perfume to your hands may seem like a quick and logical way of enhancing a fragrance's scent. Still, perfume on your hands can lead to potential staining—especially if you have an unexpected run-in with hands-on activities, like eating or drinking. Also, you'll also be touching other people and objects, which is a major no-no when it comes to fragrances.

Armpits
The skin in your underarms absorbs fragrances quickly and holds the scent for a long time (sometimes even the next day). This can potentially cause many health problems, especially if you're using a perfume with irritating chemicals.

Eyes
The skin around the eye area is extremely sensitive, so it's no wonder that spraying perfume near or directly into your eyes can be a big no-no. Traces of the fragrance might remain in your eye area even after it dries, leading to irritation.

As for glitters, our advice is to apply it on your cheekbones only, and you'll still get a beautiful glow.

Lips
Applying fragrance to your lips can be a bit tricky, mainly because they are constantly moving. While the skin on your lips are fragile and absorbent, it's better to use lip balms and glosses with a hint of fragrance rather than spray perfume directly onto your lips. In fact, it's pretty much impossible to control how much fragrance you get on your lips, which makes it an even more significant risk.

Genitals
If you're not dating anyone and are just looking for an excellent way to have some harmless fun, then we'll gladly let you in on a little secret: spraying perfume directly onto your genitals may feel pleasurable at first, but the scent usually fades within minutes, and it can lead to problems with your skin.

The Best Place to Spritz Your Perfume
The pulse spots on your body, such as your wrists, neck, and the back of your knees, are the most significant areas to spray perfume. Your favorite scent will not irritate your skin if you apply it to these heat-emitting places.

Conclusion
Spraying perfume on your hair, hands, armpits, and genitals may seem like a good idea, but in reality, it can lead to many problems. As for the best way to apply your fragrance, apply it on the pulse spots on your body.
