The Ordinary Hyaluronic Acid 2% + B5 review

Hey guys, 

I’m back with another The Ordinary product review and this time it’s their Hyaluronic Acid 2% + B5 which is said to be a ‘hydration support formula with ultra pure, vegan hyaluronic acid’.

$12.80 AUD for 30ml/ 1 fl oz | Shelf life after opening: 12 months

Hyaluronic acid has been in the scene for a while but it’s popularity and presence hasn’t been as big as till now as more and more brands start to advertise that hyaluronic acid is present in their product. However, there has been concern surrounding whether most entry level priced hyaluronic acids are gimmicks

Hyaluronic acid when applied topically(applied specifically rather than systematically i.e. to a particular area of the body instead of throughout the body) acts as a humectant(to draw in moisture).

There has been the entrance in the skincare market of a new form of hyaluronic acid that is of ‘low molecular weight’  which allows for a more deep penetration of the hyaluronic acid into the skin instead of sitting just on the skin’s surface.

However, there have also been questions as to whether this is mostly a marketing gimmick and just loose terms being thrown around, as discussed in this article

‘ Being a very large molecule it does not penetrate and instead sits of the skin surface where it binds to water to maintain hydration, and cross links with other HA molecules to knit together a temporary barrier. ‘ [Source]

‘On the other hand, LMW-HA and intermediate-weight HA increase the expression of macrophage inflammatory protein-1a and monocyte chemotactic protein-1, which may suggest that LMW-HA is important in the induction of the inflammatory cascade. Other scientific peer-reviewed publications peg LMW-HA as pro-inflammatory by multiple mechanisms: they stimulate macrophages to produce inflammatory chemokines, induce interferons, recruit T-cells, induce IL-12 cytokines, and induce nitric-oxide synthase to produce excess NO2.’  [SourceI tried my best to understand all of this but I’m still pretty confused as to how the actual process occurs when the LMW-HA(low molecular weight hyaluronic acid) becomes problematic but from what I understand is that LMW-HA allows for more entry points especially in the scenario of the wound since as discussed earlier, HMW-HA(high molecular weight hyaluronic acid) usually stays on the surface. Thus, due to the more entry points and potentially assisting any other chemicals to also penetrate past the epidermis (the outmost layer of our skin), the healing process of the wound will be interrupted.

Overall comment

I purchased both of my TheOrdinary products(hyaluronic acid + primer) about 2 months ago before they announced that they would be acquired by Esteé Lauder. Deciem/The Abnormal Beauty Company also stated that they would not change their values after the acquistion. There has been divided opinions on this as well as in general regarding supporting brands that are managed under companies that allow for animal testing.

Where I currently stand is that I am willing to support a cruelty free brand that is managed from a parent company that allows animal testing on all its other brands BUT I will try and endeavour to purchase as little from them if possible/look for more ethical alternatives. My reasoning behind my decision is that if enough people start to support only the cruelty free brands managed underneath these big parent companies, the people in charge will see where most of their profit is coming from and thus make changes. I purchase items from Toofaced which is also managed under Esteé Lauder. With The Ordinary, I’ve only tried the hyaluronic acid + the primer and I wasn’t impressed with their primer and nothing else currently catches my eyes so if anything, I’ll probably be only be purchasing their hyaluronic acid solution till I find a better alternative.

What are your thoughts/stances on supporting cruelty free brands managed under cruelty allowed parent companies?

When I first received this, I would apply it to my skin after cleansing and toning and then immediately after apply facial moisturiser though I’ve currently been mixing it with my Isntree’s hyaluronic aqua gel cream and moist cream. (They’re also cruelty free! 🙂

Overall, at this price point, it is an effective and affordable skincare product – it has lasted me about 2 months, with about 2cm depth left in the bottle and that’s using it everyday – so if I decided to repurchase, I’d be spending less than $80 AUD(about 6 bottles) Honestly, it won’t be a disaster for me if I stop using it as I find that it’s a great supplement with my moisturisers but it won’t be a huge loss to my skin (hopefully) as I use other products containing hyaluronic acid in them but I’m not a skincare expert so I don’t know.

Thanks for reading – any advice/feedback is greatly appreciated!
