I haven’t tried a hyaluronic acids serum before, and I was given a bottle to try for survey participation. I mostly use Cosrx products in my daily skincare regimen, items from the snail and cica collections.I have to say, this serum is amazing. I have sensitive, combination skin that’s also prone to redness (fitzpatrick skin type 2.) Using it twice a day with the rest of my regular regimen has almost eradicated any redness, smoothed my skin texture, and seems to have balanced my oily and dry zones (hormonal breakouts notwithstanding.)If you haven’t tried a hyaluronic acid serum yet, DEFINITELY try this one. My stupidly sensitive skin is totally happy with it and looks even better for it. 10/10 have already recommended it to everyone I know!
I am using tretinoin recently and needed extra hydration. I used it just few times but I think I can see the results. It locks the moisture on skin. I feel more comfortable in winter and tretinoin combination. I also use end of my hair after shower. Then I apply a hair oil. My hair is so soft. I just don’t like the package, very bulky.
Excellent quality HA! No weird or perfumed scent. I use daily mixed with other serums like a copper peptide or after with the Cosrx Balancium Ceramide Cream Mist. It doesn't feel super sticky or tacky as some HA can. Only 4 stars because the bottle size is not a good value relative to other HAs that perform and feel the same like Cosrx Hydrium HA.
I wanted to give hyaluronic acid one more chance but I have given up. I have dry skin and I have tried hyaluronic acid from different brands before and they didn’t work out as well. The more I used this one by Cosrx, the more I felt my skin was getting drier and drier. I tried to use it in different steps of my skin care step and searched how to use it for people with dry skin. I even tried using this when my skin was a bit wet. When I have it on my skin, it seems ok, still not hydrating, but once I wash my face, my face seems terribly dry.
Just started using this for when I need an extra boost of moisture. It has a tacky feel when applying, but this goes away as it is absorbed. Currently my routine is: remove makeup (nighttime), wash face, AC calming liquid mild, hyaluronic acid hydra power essence, this serum (if needed), and hyaluronic acid intensive cream. Every 3-4 nights, I use the BHA blackhead power liquid after washing my face, wait a while, and then do cream. It feels a little excessive, but my crazy sensitive/dry skin has gone through a dramatic change.
this is by far the best HA i’ve used. not only it has the high concentration of Ha, the best about this serum is it also has ceramides which keep my skin hydrated for a long day! this is especially effective after micro needling facial to keep my skin supple and hydration it needs. i’ve finished one bottle and my skin looks healthier and glowy. i wish this comes with a bigger bottle like 50ml instead of 20ml so i don’t have to keep buying small bottles.
