Thanks, that was very insightful and clear. So many people complain and get dissatisfied about HA, must be due to this couple of issues with high shear and temperature.👍🤩 I am adjusting some of my methods from now on.

I have a question, if a gel serum has Hyaluronic Acid, is it better to have the skin damp and then apply it or it won’t make a difference? For example, if my skin is dry and I don’t wet it a bit, then apply the H.A, it won’t make my skin drier? I’ve seen dermatologists saying to damp the skin for the H.A to work better and I have seen others say that it doesn’t matter, so I am confused. And thank you for this video! It really helps a lot!

Hi Belinda, Most recipes I see they include the HA in the heated water phase. Is that wrong and does it affect the formulation? Should we be adding in the cool down phase?
@theinstituteofpersonalcare64012 жыл бұрын
HA will oxidise in a formula - heat increases the rate of oxidation. My recommendation for a better shelf life is not to heat it.

Hi, thank you for the video, it was very informative! I have a question, I saw that in a formulation you made in another video where you guys talk about how to choose the best active you add the HA at the end right after you add the last phase ingredients (vitamin e and preservative) but then in another where you talk about how to formulate with you tool: Create Cosmetic Formulas, the formulation is a Hydrating and Moisturizing Serum, in this formula you add the HA right at the begining in phase A... How can I know when to add it, does it make any difference? I understand now that you cannot heat it but it is still not clear for me when you add it... Is it because in one formula (the first one) you need to heat the water phase to mix it with the heated oil phase and in the second video, you do not have to heat anything at all? is this the difference? In my case I need to heat the phases... I have tried to add it in the last phase after the emulsion is made but I feel that the HA does not mix together with the formula completely, don´t you need to hydrate the HA in order to add it first like it was a gum? If this is the case, can I save some water or glycerin from the water phase and hydrate the HA with it and then add it at the end of everything? Thank you so much for your help! :)

The difference is in which mixer is used (do not expose HA to high shear) - but if only low shear is used, you can add it at the start. Do not expose to heat, it will oxidise - so if heat is not used, and only low shear, you can add it at the start.

Good information, but I’m a little confused - have purchased from a number of suppliers, and they have all said it has good heat stability, & should be added during the water phase?
@sandraq7322 жыл бұрын
Your info from Suppliers is correct - I checked with head chemist in Sydney and they confirm all good to add in heated water phase - it would only be an issue if you were to heat your Water phase for over 3 hours above 70 degrees which of course you wouldnt do.
@theinstituteofpersonalcare64012 жыл бұрын
Of course it is water soluble - you add it to the water phase - just don’t high shear medium or high molecular weight HA. It will oxidise, so heating is not advised. You don’t have to listen to me, but from my experience, low shear and no heat gives you better long term stability, so why take the risk? Adjust your method and you will have a more stable formula.

Just as I was thinking about so many questions about a couple formulations with HA (high molecular) and they got answered here, i used high shear with emulsification and now I know I have to add it afterwards :] I was wondering why it got so sticky and got a different texture and suspected the shear level, thanks Belinda :D By the way, if we're using it as a gelling agent, do you reckon it would be better on its own or does it function well with a gum like xanthan smooth? c:
@CrimsonDip2 жыл бұрын
now that I think about it is xanthan gum also shear sensitive? what about other polymers? it would be really great if you could do a video about cosmetic ingredients and their shear sensitivity/resistance :]
@theinstituteofpersonalcare64012 жыл бұрын
If you are using high molecular weight HA as your gelling agent, then you don’t need xanthan gum - it could just make it cloudy and sticky. Polymers - you have to be careful with, treat them as if they are shear sensitive unless the supplier tells you otherwise. Xanthan gum/natural gums are not shear sensitive.

Thank you very much for the information. I thought that low molecular weight HA was associated with skin irritation. My question: How would you mix the different weights of hyaluronic acid in a formula? (Asking for my Mom)
@theinstituteofpersonalcare64012 жыл бұрын
You can add them directly to water. No, low molecular weight doesn't cause skin irritation, it can cause a rush of internal moisture to the skin though, that can be described as warm or tingling. It will settle shortly after use, or use a lower input particularly in the less dry skin types (like Asian and African/Caribbean) - those skin types will tend to 'feel' this sensation more.

You recommend no more than 0.5%, and so does a cosmetic supplier i use, but why do the most famous serums contain 2% ?
@theinstituteofpersonalcare64012 жыл бұрын
They may be using it as a gelling agent - 2% as a gelling agent is perfectly acceptable, this would be the high molecular weight form. You don’t need more than 0.5% for efficacy/performance - but 2% is used for gelling. Watch my HA gel with sodium PCA video: kzbin.info/www/bejne/pGTQc4Zthp2Hl7s
