Is the Pixi Glow Tonic Ruining Your Skin?

Is the Pixi Glow Tonic Ruining Your Skin?

It’s no secret that I love the Pixi Glow tonic.It exfoliates nicely and doesn’t really irritate my skin. Or so I thought. 

However, after a video I watched on Youtube, I realised that my skin actually gets irritated when I am using it, it just never really occurred to me that it might have something to do with it having caustic soda as an ingredient. The irritation is minor – my skin turns red the moment the toner touches it but the redness subsides in a few seconds. But that was enough for me to go into a bit of a frenzy. My exact words were ‘I’m going to get all wrinkly by the time I turn 28!’. I may have overreacted a little.

So I started reading more on the whole „Is Sodium Hydroxide Safe in Skincare“ thing. And here is what I found.

WHAT IS SODIUM HYDROXIDE?

It is also known as lye or caustic soda. An inorganic compound made up of sodium cations Na+ and hydroxide anions OH-. It has pH of 13, which makes it highly basic same and it is very soluble in water. It’s used in cosmetics and personal care products, but it is also used in soap, detergents, drinking water and other products, including as a drain cleaner. Yikes.

SO, WE USE IT AS A DRAIN CLEANER. COOL. BUT WHAT'S ITS FUNCTION IN COSMETICS?

sodium hydroxide

Sodium Hydroxide is great when it comes to holding the pH of products. It is an alkaline ingredient with pH value of 13 and as we remember do we? from chemistry classes, pH can be anywhere between 0 and 14, with 7 being neutral, pH of less than 7 – acidic, and a pH value of more than 7 is known as basic, which could also be alkaline. е The skin’s normal pH is slightly acidic, between 4 and 6.

Cosmetic products usually contain a small amount of sodium hydroxide in order to adjust the pH. 

Please note that if a product is too alkaline it can damage your skin. A study on skin products found that using an alkaline cleanser even just once can do a lot of damage to the skin by disrupting its acid mantle. And not only that, but the longer you use such a product, the more damage it does to your skin.

here's the thing.

Sodium hydroxide can be harmful in products  because of the hydroxide ions.And you know exactly how dangerous the hydroxide ions are if you know the pH of the product.

Basically, if the pH of the product is at 7 or below, it has the same or less concentration of hydroxide ions than plain water. This is completely fine, you need not worry about it. However, you need to be careful if the pH is too low.

You need to be wary if a product is at pH above 7 and worry if it is above 10. The higher the pH, the more dangerous the hydroxide will be. Usually, anything below 10 is fine if it has short contact with the skin (that is, if you rinse it off).

PIXI GLOW TONIC IS AT PH VALUE AROUND 4-5.

What this means is that the product is not dangerous for your skin despite it having sodium hydroxide in it. So I can relax now, I’m not doing some incredible damage, I won’t be wrinkly and sad not sure about that by the time I turn 28, everything is fine.

The issue with this product is that the sodium hydroxide is very high up in the ingredients list. It’s actually somewhere between 3rd and 5th one*, which means that it the concentration is quite high (usually the first 5 ingredients on the ingredients lists are the ‘main’ ones and the concentration of each ingredient after those goes lower and lower).

*On my giant bottle (the one in the photos, which was gifted to me by Pixi) it is listed as 3rd ingredient, and on the 100ml one I bought from Sephora it is listed as 5th ingredient. I… am confused.

HOWEVER.

Sodium hydroxide is still an irritant. Along with Glycolic acid, Butylene Glycol, Hydrogentated castor oil and 9 other ingredients in the product. If your skin reacts badly to it, I mean, it’s up to you if you would continue using it or not, but I would strongly suggest to stop using anything that irritates your skin. 

Since my skin does react a little to it, I will use mine until I hit that 12 month mark after opening it (that’s when it expires, according to the bottle) and will move on to something without caustic soda in it. 

WHAT ARE YOUR THOUGHTS? WOULD YOU CONTINUE USING IT AFTER THIS INFORMATION?
