Is Silicone Really a Bad Ingredient? Silicone其實係咪真係咁得人驚?
What are silicones?
Silicones originally come from sand or silicon dioxide and there are many different kinds with different uses. When it comes to skin care and cosmetics you can find silicones in your ingredient lists by looking for names that end in -cone, -conol and -siloxane. There are also silicone polymers which include ingredients like dimethicone. Finally, there is also a category called functionalized silicones like amodimethicone.
Why are silicones in beauty products?
Silicones have been used in creating beauty products since the 1950s! One major reason for this is they have a very low chance of reacting with other ingredients in a formula. Plus they are cruelty free, vegan, hypoallergenic and non-comedogenic! Wait, there’s more! They are great moisturizers for your skin and help formulas to more easily glide over your skin. Silicones in your skincare can increase the ability of other ingredients to more easily penetrate your skin barrier.
In haircare, silicones coat the hair shaft making your hair feel smoother and they help protect your hair from heat damage from styling. Not only does it make hair feel soft and look shiny, because it protects the cuticles in your hair it can actually help to prevent snagging and further damage to hair.
So why the bad reputation?
It’s true that silicones are not natural, and they are in fact synthetic and made in a lab. This is most likely why they have gotten such a bad reputation recently. While it’s true that products with natural and plant based ingredients are amazing for your skin it doesn’t mean that all synthetic ingredients are bad or dangerous. Research has not linked silicone to cancer or hormonal disruption and regulatory authorities around the world have concluded that silicones are not a risk to humans.
Another common misconception is that silicone is irritating for sensitive skin or clogs pores. Both of these ideas are completely false! Silicones are actually hypoallergenic and it’s the reason they are often used in medical grade products. It’s true that silicone does form a film on top of your skin, however this layer is actually very thin and is permeable to oxygen and water molecules. In other words, silicones are not very occlusive and still allow your skin to “breathe” and also still allow for active ingredients in your skin care products to penetrate your skin.
So if you see silicones in your skin care or cosmetics don’t be so quick to judge!
化學物(chemical) ≠有害空氣係chemical , 水係chemical , 就算連我哋人體都係有不同嘅化學物組成，好多時候廣告同新聞都過度扭曲化學物呢三個字，總之就嚇死人啦
