Hyaluronic filler sérum

I miss it and I would love to buy it thank you 😊

Hello Sabrina,
Thank you for your interest in G.M. Collin! At the moment, our fabulous Hyaluronic Filler Serum is exclusively available through authorized G.M. Collin spas and aesthetic salons. We suggest you to visit our Spa Locator on our website to find a spa near you. Thank you!


This HA Filler is a total game changer. Adding this product to my GM Collin regimen has completely changed the suppleness, firmness and hydration of my skin. I can’t leave out the best part which is, my fine lines around my eyes, upper lip, neck and décolleté have almost vanished after two weeks. This is now my, “liquid gold” product of my skin care routine. I love this HA Filler so much!

The best serum to try this fall

I used it morning and night after my toner. Love its texture and the scent. My skin was well hydrated and plumped-up. It is a must in Fall season.

Yes Please!

I am beyond thrilled with the new HA Filler. It not only leaves your skin soft and supple, but the fine lines fill in almost before your eyes. I have only been using it for 2 weeks, but by all I've experienced so far, this is a keeper!
