Beauty is in the eye of the beholder- but since our survival is largely driven by sexual selection.
-
We often attempt to accentuate our features with makeup.
-
So what exactly is in makeup products, and should we trust these substances that we apply to our bodies?
-
Could makeup actually be bad for you?
-
Historically, ancient Egyptians would grind up a mineral substance containing primarily lead sulphide to rim around their eyes, creating the sultry cleopatra look.
-
Little did they know that lead is a potent neurotoxin, which can lead to learning and behavioural difficulties in children and decrease fertility in both men and women.
-
Later, In 1891, creams, lotions, and blush containing compounds of the radioactive element radium were also sold to women in Europe, promising a youthful glow - until the harmful effects of exposure to radioactivity was discovered, that is.
-
But makeup has come a long way, and now there are only trace amounts of lead found in our products.
-
Lead is found in nature and is therefore an unintentional contaminant from the manufacturing process.
-
An FDA study of 400 tubes of lipstick found concentrations ranged from 0.026ppm to 7.19ppm of lead, which is under Health Canada's limits of 10 ppm.
-
Lipstick is about 47% oils, 36% pigments, 17% waxes and 5% other components including preservatives.
-
The oils are primarily castor oils, extracted from a bean which contains the protein ricin – one of the most toxic substances on this planet which has been used as a biological weapon.
-
However, the process of extracting castor oil involves heating, thereby denaturing ricin and rendering it inactive.
-
Pigments now use synthetic dyes due to cost and production efficiencies, although traditionally, red pigments were extracted from dried and crushed cochineal insects.
-
Some blue pigments are created with ferric ferrocyanide.
-
Cyanide is extremely deadly, however in this compound structure, cyanide has a very strong bond to iron.
-
As a result, it is unable to come apart to poison us by eye shadow.
-
When it comes to mascara, we recommend tossing the tube after three months of opening.
-
Harmful bacteria of the Streptococcus species and certain fungi were discovered thriving in 36.4% of mascara tubes.
-
And this is especially important for contact lens wearers, as bacteria can easily enter the micro abrasions caused by the lens itself.
-
Parabens have been a big concern as well as they're in a myriad of cosmetic products.
-
Paraben works by mimicking estrogen and binding to estrogen receptors.
-
This can cause the expression of genes to be changed and communication within cells to be altered.
-
Additionally, it can lead to the growth of certain breast cancer cells.
-
However, many products are switching to paraben free - and a lot of research still needs to be done in order to reach any definitive conclusions.
-
We made a YouTube makeup tutorial parody on Asap thought, to show the science behind chemicals being used for the common makeup products.
-
How about looking with ridiculous and having some laughs?
