This has been my go to for HA serums for a couple years. I've tried others and they just don't have the potency and staying power of Replenix. I use in the evening on my neck with a Neutrogena cream overtop. It helps smooth and soften the crepey look of my 47 year old neck. I see a quick difference if I take a few nights off. Skin still feels soft and full of moisture the next morning.
