    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.)

    You get full claim value…at any inclusion rate.
