I used the [Product Name] hyaluronic acid serum with my microneedling device. It provided a good amount of hydration and helped with the glide of the pen. The texture was slightly more viscous than I expected, but it wasn't sticky. It did a good job of keeping my skin hydrated post-treatment, and I didn't experience any adverse reactions. If you are looking for a hydrating serum for microneedling, this is a solid choice.
