milk kefir in cosmetics
Could we put kefir milk fresh in our cosmetics and especially in face creams? And if you need a refrigerator for preservation?

This is a cosmetic site. I believe you are looking for a cheese or yogurt site.
Good luck.

A rude, unnecessary, and weird response.

Whatever you put in your product you have to be able to demonstrate safety. So, if you put kefir milk in your product, how would you demonstrate that the product is safe to use?
When you use standard industry accepted ingredients, the suppliers will have conducted safety testing and you can be better assured that the product will be safe to use. If you put ingredients like food or from other industries, then it is up to you to conduct safety testing like HRIPT, stability testing (which should be done anyway), preservative efficacy testing, etc.
So, yes you can put it in the formula. But only if you are going to conduct proper safety testing.

Of course you can, but the benefits will be hard to pin down. The probiotics will be deactivated by the preservative. The benefits will most likely be limited to moisturization as a factor of the lipids and fatty acids in dairy products. Probably not worth it

Milk products are seen as highly nutritious when taken internally. Is it the same when applied externally? One of the problems with milk products is the high bacterial loading which has potential to flow through into the finished product. And believe me, I have learnt the hard way about the bacterial loading of food grade raw materials being added to skincare products. But that doesn’t stop brands wanting to leverage off the “good”. If you are adamant about this direction, then I would look at adding a label claim amount of milk and I recall from some years ago that I think Croda had a milk powder they sold into personal care. Either that or you could consider using a small amount of UHT milk. And then depending on what claims you are interested in I would then consider adding a microbiome Bacillus ferment product that has been developed for personal care. And of course you would need to perform the usual PET and stability.
