Hyaluronic acid makes skin dry
I understand that HA is often found in serums, and that this step is followed by a moisturizer to prevent dehydration. However, some moisturizers such as SkinMedica Ha5 Rejuvenating Hydrator or DEINDE barrier-building MOISTURE CREAM contain quite a lot of HA. Could this cause dehydration of the skin in a dry environment?

What makes you say it has a lot???
Are you privy to the formula?
I only looked at the 1st one…and the HA is below the 1% line….so probably typical use rates.
The marketing is clever enough to discuss 5 types of HA….to throw off your cognitive abilities.
I saw nothing there to claim more than claim levels of HA.
It seems to have the typical humectants that do all the work…and get none of the glory. 😉

I just think the total content of them would be around 1%.
How much is enough? I guess 0.3% is ok, right? I have read some articles, they even use only 0.1%

How much is enough? 😆 NONE is enough.
Based on the fact that after water they have two industry standard humectants… I’d suspect they went .01% X 5 versions….and came to a rather industry standard .05%. 😉
That is an ingredient…..where less is almost always better. (But an ‘ell of a CLAIM ingredient.)
