Malar bag reduction
Been using a whole bunch of stuff from the ordinary, Buffet, Euk 014, mosturising factors HA, rosehip seed oil, alpha arbutin, mandelic acid and this marine hyaluronic acid, so dont know exactly which reduced my malar bag, but I think hydration played a major part in filling in over it, to give a bl...

Provides decent surface hydration. Nice alternative to hyaluronic acid if you live in a very dry environment. Also, I perceive a moderate brightening effect from daily use. Would recommend.

Great alternative to the $100 bottle of Elemis
Love it. Was using Elemis which is very expensive. Was hoping it was similar. I'm begging to love this line of products and gradually changing over. Great selection of products. Would highly recommend to try if you haven't.
Refreshing
I really like this. My skin stays soft for hours, and this product is a little lighter and less sticky than the regular HA serum
Hydration in a bottle
I've had dry skin all of my life. Now in perimenopuse my skin is starting to be extra dry. This serum is a lifesaver. It moisturizes to the gods. Will be buying again
Pleasantly Surprised
I figured I'd try a less expensive brand than usual and im so glad i did! I was amazed at how much this lightweight formula hydrated my skin. I use twice a day and love it
amazing
i generally have dry skin (especially during the colder months) which can be sensitive sometimes. i LOVE this serum. the consistency is basically like water & i use it directly after my cleanser & it leaves the skin very hydrated throughtout the day. highly recommend 🩷

- Q
Can you use this with microneedling
- Asked by vic
- Official Answer By The Ordinary - Brand EngageKindly note that our products have not been tested for use after invasive treatments such as dermarolling or microneedling. However, we would recommend avoiding the application of any Direct Acids, Vitamin Cs and Retinoids for 24-48 hours after these treatments. That said, procedures such as microneedling can cause disruption to the skin barrier, making it important to keep skin hydrated, especially after treatment. You may wish to explore using Hyaluronic Acid 2% + B5, which can help keep skin hydrated and support the moisture barrier. Please be sure to patch test prior to use, and for specific recommendations regarding post-procedure care, please consult with your provider.Was this answer helpful to you

Hello so i have really sensitive skin since my skin barrier is damaged but my skin is also very dry. Is this the best product to use for my skin or do you recommend something that is more skin sensitive? I just would not want to irritate my skin more or damage it
- Asked by jen
- Official Answer By The Ordinary - Brand EngageHi! Marine Hyaluronics is great for hydration. However, you may wish to explore Hyaluronic Acid 2% + B5 instead which has added ceramides specifically for barrier support.Was this answer helpful to you
