It probably works for some people, but didn't do much for me.
Love the product. Noticed a difference in my skin's hydration within a couple of days. Live in Canada Toronto area and it's cold right now. I use it directly on my skin after a shower and also mix with essential oils for topical relief from arthritis. The packaging is lovely as well, so no need to hide it if you use it frequently.
it is a liquid, not what I would call a serum, however, it's working just as it should. you cannot beat hyaluronic acid
I love this stuff!!
