Allergic-reaction---ugly-and-deadly

2. Allergic reaction - ugly and deadly

Allergic-reaction---ugly-and-deadly_1_0

It is extremely importantthat whenever we buycosmetics, which we have not used before, we check that the product will not cause an allergic reaction. This is especially important for peoplewho already have some allergy to something (not only cosmetics) or have sensitive skin,but it should not beforgotten that each of us, at any moment, can unlock an allergic reaction - even to cosmetics we have been using for years.

Allergic-reaction---ugly-and-deadly_1_1

The reaction can vary greatly - from a slight rash- through edema to a very severe reaction and anaphylactic shock, which leads tosuffocation and death.

Check as follows. Place a small amount on the inside of the elbow and wait between 48 and 72 hours. If you have redness, swelling,itching or burning , do not use thisproduct.

Allergic-reaction---ugly-and-deadly_1_4

In order to avoidirritations, it is appropriate to choosecosmetic products with fewer ingredients , and not to spray perfumes directly on our skin. It is enough to blow through the air in front of us and pass through the cloud of fragrance or from a distance to splash a little on our clothes.

3. Does 'bio', 'organic' and 'vegan' really mean healthy

Does-'bio',-'organic'-and-'vegan'-really-mean-healthy_2_0

On the packaging of almost all cosmetic products can be seen inscriptions such as "hypoallergenic", "dermatologically tested" or even "bio" and "organic", and some nail polishes already say that they are "vegan".

Does-'bio',-'organic'-and-'vegan'-really-mean-healthy_2_1

There is not enough strict regulation on cosmetic products and their labels, so anything can be written on them without it being true. Including whether it has been tested on animals. However, regulation in Europe is better than in the US, for example, where cosmetic products are marketed almostwithout regulation and control.

Does-'bio',-'organic'-and-'vegan'-really-mean-healthy_2_2

Does-'bio',-'organic'-and-'vegan'-really-mean-healthy_2_3

Often cosmetics, which are labeled as organic ornatural, contain many synthetic ingredients and are no different from others. If you look at the label, you will see that the presented as the main ingredient actually represents only 0.1% of the composition and everything is just a commercial trick.

It is also good to keep in mind that even if it contains substances of natural origin, this does not necessarily make them safe. An interesting example is the belladonna plant or crazy herb (Atropa belladonna) - it was used as a drug, as a cosmetic agent (the atropine contained in it expands the pupils, which was considered attractive), but also as a poison.

We are also warned about the same danger by Netflix's documentary series Broken. In one episode, a young woman recounts how she bought Kylie Lip Kit lipstick, influenced by the enthusiasm of friends and youtube subscribers. But to make it cheaper ,she made the purchase on eBay. Of course, a fake lipstick arrived- but she didn't find out about it until her lips stuck heavily. It turned out that in order to achieve the necessary consistency and shine,the manufacturers put glue in the lipstick!

5. The hidden shelf life and when to part with the eye mascara

The-hidden-shelf-life-and-when-to-part-with-the-eye-mascara_4_0

It is extremely important to monitor when the expiry date of the cosmetic products we use. Especially those that come into contact with the eyes or are used on the face.

The-hidden-shelf-life-and-when-to-part-with-the-eye-mascara_4_1

This is because since even once we have used some cream or eye mascara, bacteria fall into themthat detect a suitable breedingmedium, and over time the old mascara can cause us eye infection,and the cream - rashes.

It is no coincidence that on the package there is often a small symbol of an open jar and next to it it says 3 m or 10 m. This means that even if our favorite eye mascara is still full, if it's been 3 months since it first opened, we should say goodbye to it. From personal experience, I know that this is not easy, especially for ladies who do not use it every day anyway - so for every occasion we have to buy a new spiral...

6. Are the testers safe and what is the resemblance between makeup and underwear

Are-the-testers-safe-and-what-is-the-resemblance-between-makeup-and-underwear_5_0

We all know how difficult it is to judge whether a lipstick will look good on us and what its exact color is, so most cosmetics stores offer testers for general use by customers. But is it safe to usethem?

Are-the-testers-safe-and-what-is-the-resemblance-between-makeup-and-underwear_5_1

The obvious answer is - no. As we havealready said, cosmetics are easily contaminated with bacteria, and this can make it dangerous, especially if used by many peopleat the same time. Just as we don't share our personal underwear withother people - weshouldn't share our personal cosmetics either.

<ul>
<li style="font-weight: 400;">Phthalates (phthalate, diethylphthalate, DEP) - used in hair spray, nail polish, perfume, Lotion, shampoo, aftershave, food and toy packaging, as well as in many other products.

Some phthalates may adversely affect reproductive abilities, as well as development in children.

<li style="font-weight: 400;">Formaldehyde ( formaldehyde), formalin - it is a carcinogen and can be found in nail hardeners and nail polishes, and some hair smoothing products secrete formaldehyde in the air when heated.</li>
<li style="font-weight: 400;">Bottled hydroxyanisole (butylated hydroxyanisole, BHA) and bottled hydroxytoluene (butylated hydroxytoluene, BHT) - these are preservativescommonly used in lipsticks and moisturizingcosmetics.
