What is it: a hyaluronic acid serum
Why do I like it: provides a good level of hydration, and another layer that is particularly necessary in winter, though I do use it all year.
Do you need it: Kinda... if you were going to make a start with serums, I would start here. Vichy and First Aid Beauty also do good hyaluronic options but I find Niod to be higher quality.
How long have I used it: About a year
How much do I use: 1/2 a dropper full (not a huge fan of the dropper-style package, but it's not too cumbersome)
Worth the cost: to me, yes. You could certainly spend less on hyaluronic acid, but I like to go for a higher quality one.
Would I repurchase: Yes, I plan to
