I use this for microneedling and it has fantastic slip. I watched some aestheticians on youtube before diving in and this was one of the recommended products. It doesn't have any other additives, just pure HA to get the job done. I drop some of this HA serum into a mini bowl and use a fan brush to apply it onto my skin before microneedlig with my pen and then reapply if I'm feeling a little tugging. I probably used a good 1/8 of the jar during just one session (several times over my face and neck) but it's affordable enough that I don't mind going through it faster than I typically would. Now that I've found this, I intend to have this be a staple in my microneedling routine. I've already purchased my second bottle just today.

I’m happy with this skin product and will continue to order as long as I’m able. Thank you.
Love this product. Been using it for years. I’m old (77 yrs. old), but my skin still is pretty firm and a few wrinkles don’t bother me. No plastic surgery for me. My skin feels soft and dewy and I’d recommend this product to anyone. Affordable also.

Good product
Very good product. But very thick, so if you don't like sticky product you may not like this but after a while your skin just drinks it so you won't feel anything. NAFE safe!

working wonders on my skin
I was kind of nervous about ordering this - but it's actually worked out so well. I use it at night, mostly, and switch between cupping and micro needling at home. My skin is smoother, plumper, and overall glowing. I'm approaching 60 years old. I only wear mascara and brow tint. I have never really used products like these on my face - more of a 'crunchy' girl, if you will. Just some info to help you gauge my experience. I have also been using it on my scalp. In my experience, it is helping my 'old lady' hair to be a bit fuller and definitely resolving the dryness. The only con for me is getting the product out. It's a bit challenging. I'm going to try another brand to see if that's standard presentation.

Works well! But pills a lot
Pills a lot when I put any other serum or moisturizer over it. If only using this then it is amazing and very lightweight/ easy to use for anyone. No scent just simple ingredient

A NEW FAVORITE!!
I love this product!! It slides nicely into the skin and absorbs quickly without any sticky residue. It's gentle enough to swipe a little over the eyes and lips. I've noticed a difference in my skin's brightness and softness. Great for summer because the formula is very light. I bought this as a recommendation from a top notch esthetician, as an affordable alternative and I'm so glad I did. The price is amazing for the quality of what you get. It's definitely a new, daily staple in my skin routine.

Microneedling Must Have
I purchased this as a recommendation from an esthetician online to use when microneedling. This does give a good amount of slip and if you put some in a small dish and use with a brush, it goes a long way. Price is fine for the amount.

Ich (52 J.) bin immer mal wieder auf der Suche nach neuen Antiaging Pflegeprodukten (siehe mein fortgeschrittenes Alter ; ) . Ich bevorzuge natürliche, organische Inhaltsstoffe und auf jeden Fall mineralölfrei, parabenfrei und parfümfrei. Wenn irgend möglich ohne Tierversuche. Diese Voraussetzungen werden erfüllt! Was die Antiaging Inhaltsstoffe betrifft, stehen sie denen in anderen vergleichbaren Produkten in nichts nach. Allerdings sind diese meistens doppelt oder dreifach so teuer. Das Produkt selbst lässt sich gut verteilen, klebt nicht und man kann, bei Bedarf, sofort seine gewohnte Pflege darüber geben, was bei einem Serum besonders empfehlenswert ist. Erwähnenswert finde ich noch die Pipettenflasche. Beim herausnehmen der Pipette ist es oft der Fall, das sich auf der Außenseite des Pipettenhalses Überschuss befindet. Bei einem Gel, wie in diesem Fall, ganz besonders. Wenn man dann die Pipette in die Öffnung zurückschiebt, bleibt dieser Überschuss oft am Rand kleben. Was nicht nur eine ärgerliche Vergeudung des Produktes bedeutet, sondern auch unhygienisch ist. Bei dieser Flasche befindet sich aber an der Öffnung ein Art Umrandung, sodass die Pipette sauber herausnehmbar ist, und sauber wieder in die Öffnung hineingeschoben werden kann, ohne das man aufpassen muss, das nichts danebengeht. Also, alles in allem ein tolles Produkt, auf jeden Fall empfehlenswert und für mich ein Nachkaufprodukt!!!

I really enjoy the product itself — it leaves my skin feeling firmer without that tight, pulled sensation. It layers beautifully with other skincare and sits well under foundation too. A great performer at a very accessible price point. However, the packaging is a letdown. I’m not a fan of the plastic casing, and the dropper is particularly poor — I ended up removing it and just tipping the product onto my fingers. It feels a bit cheap, which takes away from the overall experience. While I’m impressed with the formula, I’m unlikely to repurchase unless the packaging improves.

One of the best hyaluronic serums I have used, definitely better than The Ordinary or overpriced La Roche Posay , 100%. I use it for hydration, microneedling and high frequency treatment.
