Vitamin c serums are INCREDIBLY easy and inexpensive to make on your own. You can make a fantastic one with distilled water, l ascorbic acid powder, and glycerin. Technically you don't even need the glycerin, but it'll make it a lot more pleasant and spreadable. I usually make a batch of 20% every two weeks and store it in the fridge. Even the holy grail of vitamin c serums, skinceuticals, has a *super* simple formula, so the pricepoint for these concoctions are outrageous!

General consumers don't use proper technique to prevent contamination. They touch the surfaces. They leave the bottle open for awhile. An airless pump has a hole, and it will indeed get exposed. But that will immediately come out with the next use. I prefer that over a much larger hole opening and closing.. with a dropper that can get contaminated, and air being exchanged regularly (along with microbes, oxygen, and pollutants).

For the oxygen part, you're not wrong, but the point is rather that airless pumps can and do generally leak. As in, all the time, not just during use. Dropper bottles can achieve a better seal (generally speaking). And the time you're using the product is a fraction of the time it's standing unused, so the time it stands unused is more relevant Both have their pros and cons, and the dropper bottles definitely need a whole lot more care, it's not like they're universally better by any means

@@jeon_artemis - That iiis warranted concern/caution. But I'm okay with the risk, because plenty of companies sell glycolic acid in the same glass bottles, and The Ordinary (what I'm using) also uses the glass bottles for other AHAs (acknowledging that there's more going on that just 1 ingredient). The Ordinary in particular doesn't use glass for the glycolic, but I'm 85% sure that is just because glycolic acid much cheaper than the other AHAs, so either they have a rather large 240ml glass bottle, or they only sell a baby 30ml bottle worth 2.56 AUD (where I am), or about 1.64 USD. I did the math lol. Better for them to use a larger bottle that is just plastic.

Thank you for explaining this! To clarify, because you did say that you still liked them but they’re not far superior than a dropper, does it cut the shelf life of the product? I had recently bought some for traveling, but then I found I liked it better for application since I can just press down with a finger instead of getting skincare on twisted lids. I’d like to maintain using that pump system, but I want to ensure I’m not ruining products. So, that said, as long as I don’t put vitamin C or retinol in them, are they fine to use? Also, what about things like copper peptides? Ideally, we keep them in the original packaging because it was formulated in it for a reason, but if we do stray outside of that how do we do so safely? I hope my questions made sense… thank you as always, I appreciate all of your time, work, energy, and care 🫶🏻

You dont find airless pumps in chem labs for several reasons not related to airtightness: 1) multimaterial airless pumps pose compatibility issues for certain reagents 2) airless pumps are comparatively MUCH more expensive than bottle with threaded caps. 3) Substances in chem labs need to be easily ACCESSIBLE via pouring or scooping, an airless pump would be super inconvenient Amongst other reasons. Droppers are fantastic for many cosmetic products, but not because they allow for less O2 interaction with the bulk compared to airless pumps... This comparison is misleading.

Thanks for your comment! Yes those are reasons too, but a big reason that I didn't go into detail about is being able to create a well-sealed argon/nitrogen blanket over the product to protect it before it reaches the consumer, which works much better with screw-top packaging than a relatively leaky airless pump. Yes there can be a locking mechanism in the nozzle, but it's fluid-tight which is not necessarily gas-tight - that's why special systems needed to be developed for more airfree products like Avene's Sterile range. This video wasn't to say that droppers are much superior to airless pumps, but rather to argue that airless pumps aren't a far superior option compared to dropper bottles for air sensitive products like LAA serums, as is commonly stated, including by a brand whose products in airless pumps did worse in the retinol stability study than the Revolution dropper product.

Im guessing not unless its squishy rubber touching squishy rubber to form a gasket. Like she said, there’s a lot of hard components forming the seal and that is not airtight. Check to see if there’s a rubber gasket type closure or if it’s plastic threading (like when you unscrew shampoo bottles, you can see the cap is harder plastic (not like a rock hard but not squishy rubber). I work in a lab too and that’s how all of our air sensitive components are stored, with screw caps + gasket type component. This includes 100% ethanol which is highly volatile.

I think I remember a while ago you saying that products like ones in dropper bottles are formulated with their intended use in mind, in terms of preservatives. And that companies are not expecting you to take the dropper and smear it around your face and then put it back inside the bottle contaminated, and thus they don’t have enough preservatives to account for that contamination. Is that still the case since it seems like every single person on YT and TT insist on rubbing the dropper into their skin with the product? This has become of my hugest pet peeves and it doesn’t seem to be going anywhere. Do these people just have really yucky/germy dropper bottle products? Grosses me out every time I think about it.

As someone who works in cosmetic packaging, this is not true... Pump mechanisms internally lock to prevent contact with the outside air through the nozzle. Yes there's a hole in the nozzle, but inside the hole, the pathway is plugged when the actuator is not depressed. If what you are saying is true, then an airlesss pumped placed in a vacuum chamber would leak from the nozzle, which does not happen.
@LabMuffinBeautyScience
9 ай бұрын
That's not true - fluids experience surface tension unlike gases, and water has especially high surface tension, so something that's water-tight isn't necessarily gas-tight. If standard airless pumps sealed against air well, special airless systems wouldn't have to exist, and airless pumps would perform much better in stability testing for air sensitive ingredients (but they don't).

99% of people i see using droppers touch their face with the dropper while putting on the product. I see professional makeup artist do this as well. So I think that the pump is better as their is less contaminants getting into the product. Also the forumar is made to withstand the amount of contaminants for propper use so the droppers may not be able to handle how most people use them.

That is not an airless pump- it’s a threaded pump with a vacuum mechanism and a twist-lock . A true airless pump is a snap-on and is ONLY open when the pump is pressed down- it does not have an opening letting air in all the time. Once it returns to the “off” position, it’s “shut off” and air doesn’t breach it. It’s also not used in labs because they’re crazy expensive in comparison to droppers. Droppers are fully removed, leaving a ton of air to come in freely through the huge opening. Airless is better, no question. But you pay for that difference.

As stated, airless pumps have a whole bunch of tiny gaps between components, not just the hole at the top - it's a necessary limitation of any multicomponent packaging. Oxygen can pass through many plastics, any tiny gap is no barrier. I have a vitamin C serum in a special airless pump developed with "aerospace technology" and it turned just as brown as the ones in droppers.
