Simple formula, good to maintain the skin balance and control the breakout. The downside is a little sticky/rich for summers. Would like to repurchase when move to a colder place.

I really like this serum. It feels nice on the skin and is hydrating, even a small amount. It mixes well with other products. I have re-purchased it a few times already.

This is a gentle, pleasant serum that goes on smoothly. The only thing is I am not really noticing any positive changes in my skin's moisture or subtleness. I may just need more time to see how it improves my skin. It doesn't really have a fragrance, and has been non irritating to my skin, which is always good. May be best layered under another moisturizer.

I totally agree with the other review! With winter now upon us, the Replenix Pure Hydration Hyaluronic serum is a wonderful addition to my nighttime regimen. Try it, you'll love it!

I have used skinceuticals hydrating B5 serum for years, but gave this one a try recently and saw even better results. No oiliness, just a moisture boost when layered under your own moisturizer or even alone under sunscreen when heading to exercise in warmer months. Thank you for offering Topix products - their retinol night serum is great as well.
