Problema solved: vegetable oils are fermented by yeast inoculation in a controled enviroment. http://cosmetoscope.com/wp-content/uploads/2020/03/PT_FermentoilEN-1.pdf Thank you!

...or the raw material Is fermented prior to extraction? https://www.researchgate.net/publication/320420429_Effect_of_Lactobacillus_plantarum_on_olive_and_olive_oil_quality_during_fermentation_process. Apparently there can be some benefit

Pritty much for me. For instance if you have Sal butter in your formula, you cannot ignore its specific 40+% of stearic acid content, so different form other butters.

@Perry I don't know how, but you manage to keep this forum polite, respectful and interesting of course. Open to anyone. A great place to learn. Thanks to you and to all generous members.

I will not feel frustrated of you think better to remove this misinforming content from the forum. Sorry for posting.

Oh no, Perry! This site popped up in first page while googling for vitamin c and blackheads https://www.google.com/search?client=ms-opera-touch-android&channel=new&espv=1&q=vitamin%20c%20blackheads Amoung several unusual statemants, I wa…

Have you considered this study? Please have a look at the "Fig. 4. Representation of the permeation and localization of various hyaluronic acid (HA) after fitting by their reference spectra and by comparison to the (a) positive (glycerin treat…

Providing that' PENTAVITIN® has the ability to bind to free lysine amino groups ( ε amino group) of stratum corneum proteins which results in a covalent complex with high water retention. ' that can only be removed by the natural process of…

I believe that betaine sooner or later is doomed to get a fishy smell by itself, you just accelerated somehow the process.

(Quote) If this is Hyacare 50, my eyes are very sensitive to this ingredient.

My guess is sucragel CF or XL, as I wrote. Caprylic/Capric Triglycerides instead of almond oil.(Quote) No idea :)
-
@ngarayeva001 there's a formula with high glycerine content (about 45% if you consider that sucragel AOF already contains about 50% of glycerine) found here: BLOOMING BATH OIL ASucragel AOF 40.00AOrganic Glycerine 25.00BSunflower Oil Helianthus A…

@Gladtobe My guess is that Deciem Petrowhat? balm is made with sucragel (cf?) @ngarayeva001 I don't know if this may help you https://www.cossma.com/fileadmin/all/cossma/Archiv/SciencArtic/COS1111_30_ALFA_CHEMICALS_Sucragel_IMPAG_Kosmetikseminar_201…

Yes @ngarayeva001 I agree with you and there are more and more products with a lot of propanediol, maybe it's just greenwashing but I like it too.

According to Zemea papers the difference in irritating potential seams rather important. Can we believe this? Evaluating 1,3-Propanediol for Potential Skin Effects It has been hypothesized that dipole moment may influence skin irritation response…

But the reason you get darker is more likely related to L-dehydroascorbic acid or DHA which is the primary oxidation product of ascorbic acid. That's just a Maillard reaction, not a damage to your skin. https://labmuffin.com/vitamin-c-can-stain-ski…

Your fake tan tells that vit C has oxidized in the bottle or over your skin. In order of ruling out the first case, consider that in your list there are ingredients that play better at different pH levels, so it's not unlikely at all that something…

https://www.zrobsobiekrem.pl/pl/p/Stabilna-forma-witaminy-C/741 I buy from this Polish site since many years, not best prices but a nice list of ingredients. (Carbopol Ultrez 21 is very sensible to air moisture, try to pulverize it again)

Ready! :)
-
Thank you! I do have a small spot of SK and DMAE bitartrate waiting to be used. I'll let you know if it works :)
-
May I ask how long did you make use of this cream before the lesion was gone? No urea?
-
Thanks all of you, Doreen first! :)
-
@Doreen because a pure lipidic mix does not provide the 'moist' part as in a lotion
-
I would discuss this with your daughter's doctor, I'm sure he knows how to proceed. BTW a mix of pure shea butter and cocoa butter is very drying for the skin.
-
BTW, can you share the ingredient list?

Your suspects bring to my mind an old case: https://www.ncbi.nlm.nih.gov/pubmed/16286743

Just some tiny imprecisions :D , thank you for your time! In an other blog i've found something that seams the opposit of what originaly stated by Deciem: " some HA products at higher pHs (sometimes labelled as “buffered products”) are said …
-
I understand that the irritant potential of a salt is due, at least, to its crystallization on the surface of the skin, so pH>pKa = more salt = more irritation potential. The more salt you have in your acid, the less potent it is and potentiall…

This is the explanation I just received from Deciem: Sodium lactate has a high molecular weight. Therefore, it would stay on the skin and not penetrate which can be irritating. Experts, do you agree? Thank you
