Not the best product for post dermplaning
I was really looking forward to trying this as post care for dermaplaning, but not impressed. It just felt like a basic serum. It does feel moisturizing but it is similar to every other HA serum out there.

Smooth
This serum is very hydrating and it feels very good on my face. I would absolutely try this again.

Meh
I found this unnecessary to use when dermaplaning. I just used a nice mild moisturizer to prep skin after washing and completed the task without any irritation. This is just my opinion.

This stuff is effective & great price
I am not a skincare person, and my face has suffered for it. With the Sephora kid era phasing out, I decided to try some new products for my face to try and improve the hydration and health of my skin. This product instantly hydrates my face. I even find myself using it without dermaplaning, but it is definitely soothing to use after using a facial razor or even plucking your eyebrows.
