I was skeptical but love this

I am one of those people who buys the inexpensive version of every beauty product and often find no difference. This one time though I do have to say that their HA serum is the best I have used.

The serum is so light and feels absolutely amazing.

I love applying it after my toner, and it blends in perfectly on my skin. I can't recommend this product enough, it works so well with all my other facial products.

This product is amazing

I bought it originally when I also bought the laser. The serum makes such a wonderful difference with the smoothness and texture of my skin. I signed up for the automated delivery.

Hyaluronic Serum is the best

This serum is by far the best I’ve tried. It is not sticky so I can wear it under my makeup and the plumpness I get from it is clearly visible.

Just what I needed

What a treat for my skin! I apply this after using my Nira and it feels so nice going on! Dries quickly without any stickiness or residue. Feels like a treat that also does a good deed for me :)

4 STEPS TO GLOWING SKIN

Wash your face and pat dry with a towel.
Use the NIRA Pro+ Laser to treat large areas on your face, neck, chest, and hands.
Hold against your face to automatically fire the laser. If you hear a rejection tone, make sure to press the tip fully into your skin and try again.
Use the NIRA Precision Laser to treat hard-to-reach areas around your eyes, nose, and mouth.
Hold against your face and press the button to fire the laser. If you hear a rejection tone, make sure to press the tip fully into your skin and try again.
Maximize your results by applying NIRA Moisture-Lock HA Serum and Youth Renewal Peptide cream post-treatment for smooth, revitalized skin.

What makes this hyaluronic acid different?

Our formula combines high and low molecular weight hyaluronic acid to hydrate multiple layers of the skin—instantly plumping the surface while delivering long-lasting moisture deep within.

Is the serum safe for sensitive skin?

Yes, it’s formulated with just four clean, vegan ingredients and is free from fragrance, parabens, and irritants—making it gentle enough for all skin types, including sensitive skin.

How long will one bottle last?

With daily use, one bottle typically lasts 2-3 months, depending on how generously it’s applied.

Can I layer this with other serums or actives?

Absolutely. This serum plays well with most skincare ingredients and can be layered under peptides, retinol, or vitamin C products.
