    Preciousia,

    Please do report back on how the Ordinaries products work for you! I’m in Canada so I’m really thinking of ordering them. But isn;t the 23% ascorbic acid sold out just the other day…?

    I just ordered the niacinamide 10% and alpha arbutin 2% too! I’m already using a vitamin c serum (sodium ascorbyl phosphate). I wonder when I’ll receive those items… hehe

    But gosh, you ordered so much! How’re u going to test them all?

    According my dermatologist even vitamin C derivatives like Ascorbyl Tetraisopalmitate need air-tight packaging and need to be stored refrigerated. So I don’t know if the Vitamin C serums of The ordinary will stay stable in bottle packaging. 

    The Niacinamde serum isn’t expensive so a great option, but I’m going to try to mix some distilled water and Niacinamide myself first, I also have Dexpanthenol, Allantoin. Making 30mL will cost about 3 euros (3.50 dollars), so I can make it fresh every other day for example.

    I can also locally buy pure ECGC, Ferulic Acid, Hyaluronic Acid, Caffeine, N-Acetyl D-Glucosamine, but they are extremely expensive ingredients over here. A serum of 30mL will cost about 25 euros (28 dollar), and considering I don’t want to use preservatives, I can only store it like 2-3 days.So in the end it will still be expensive. Also Ascorbic Acid is only stable at a pH of less then 3.5. So if you making it yourself, you can end up with extremely acidic sollutions, which can irritate the skin, or a sollution that will act as a pro-oxidant.

    @Peter I am a packaging fanatic too. I have enough airless bottles to transfer ALL the bottles :) 

    Very good point… but their pricing is cheap. so can’t complain.

    That’s why I don’t DIY. I leave it to the cosmetic scientists. :D

    But where do you guys get this airless bottle…? amazon? ebay?

    @escherichia I decant a lot, anything I don’t like >> decant. Probably spend more on containers sometimes than the product sometimes. The good is that I can recycle and reuse them And fortunately they are not price prohibitive. The best packaging will minimise air, protect fr uv, & dispense the product easily, avoid bacteria introduction (dipping fingers into jars). I follow Paula Begoun’s theory on this and I am with her 100%.

    You can read more about decant /packaging on my blog. You can try Amazon or ebay but I will pm you other sources to consider :)

    I created a table to rank packaging, let me dig it out.

    Ranking different kinds of packaging. If money is not an objective, I absolutely adore airless jars!

    @escherichia I ordered idealistically. I did not think of how to introduce them practically. Any suggestions?

    If I narrow which vitamin c I like I can buy the ingredient to DIY. It is far too expensive to buy everything and allow them to expire. I am only one person, how am I going to use it up?! DIY can get more expensive than finished products. ESP mistake = bin or skin irritations, something you cannot afford to mess with :)

    @Peter it is my opinion that ALL antioxidants… need airless packaging. All my dermatologist products came in airless bottles. 

    so that refers to all the vitamin C variants… regardless of their stability. Mad hippie packaged their Vitamin C in a dropper bottle, there is 2 risks: bacteria and air. 
    i repackaged it.

    Wow… U know, should I decant the Ordinaries alpha arbutin and niacinamide into airless containers? But their original packaging are dropper style…?

    I agree with preciousia that anti-oxidants should be packaged in airless containers. I really don’t understand why Paula’s Choice packaged their 15% Vitamin C serum in a dropper, and they even start talking about a special rubber ring reducing air in the product, while if you take the dropler of, air will just flow into the product. I also wonder about their toners, they contain antioxidants, but they are certainly not airless.

    On the other hand, many ingredients that function as antioxidants are pretty stable. For example Niacinamide is very stable, also esters like tocopheryl acetate are pretty stable. And even the Skinceuticals Vitamin C + Ferulic acid seems to be a quite stable combination of ingredients, according to the patent. So I don’t know maybe the manufacturers know what they’re doing, maybe it’s like avobenzone, which is unstable on its own, but can be stabilized if octocrylene or tinosorb m is present in the product. But personally I like airless packaging, it may even reduce the amount of preservatives necessary I hope.

    Natural vitamin E is not stable. Tocopheryl Acetate is synthetic Vitamin E.

    In fact, Dr Todorov recommended we get vitamin E pills instead so it is individually encapsulated (less oxidation)
    Skinceuticals CE+ferulic isn’t full proof either… still got to throw it away after 2-3 months.
    hey packaging isn’t that expensive.. i rather not take the risk. i will be repackaging all of mine.

    i don’t know why they don’t package it in airless container… just like jars… why do they still package products in jars? the consumers like the dropper bottles (i abhor them)
