  • 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.

    一份 FDA 的報告指出有 400 個口紅被發現含有 0.026 ppm 到 7.19 ppm的鉛,低於加拿大衛生部的條件限制的 10 ppm。

  • Lipstick is about 47% oils, 36% pigments, 17% waxes and 5% other components including preservatives.

    口紅大約有 47% 的油、36% 的顏料、17% 的蠟及 5% 其他東西像是防腐劑。

  • The oils are primarily castor oils, extracted from a bean which contains the protein ricinone 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.

    36.4% 的睫毛膏被發現含有鏈球菌中危害的細菌和特定的菌類。

  • 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.

    我們在 YouTube 頻道上做了化妝教學的搞笑版,來表現化學應用在一般化妝品的奧秘。

  • How about looking with ridiculous and having some laughs?


  • Check out the parody with the link in description and subscribe for more we did science videos.
