Experiment Super Saturated Ultra Hydrating Barrier Serum - 30% Glycerin, Polyglutamic Acid + Prickly Pear for Intensive Moisture, Plump + Dewy Skin, 1.35 FL OZ - Hydrating Serum for All Skin Types

This stuff is luxurious, makes your skin glow and feel instantly hydrated and plumped. I use it after I apply my tretinoin and it feels so silky and soothing after, keeps irritation away. Absorbs and layers well. This is a new staple in my skincare routine, so glad I tried it. The ONE bad thing is it having niacinamide in it, every skincare product has it now and it’s completely unnecessary and overload and my skin cant tolerate it well anymore because it’s in too many skincare and makeup products. So I can’t use this with some of my other favorite skincare because they ALL have niacinamide in them, and it’s just too much for peoples skin. But I didn’t want to take a star away because I do love this product. Experiment, please make hydrating products without niacinamide.

This feels absolutely amazing on the skin! It’s this great burst of hydration with ZERO stickiness! It really plumps up the skin and instantly hydrates dry areas. It’s soothing on an areas of sensitivity. It provides a really healthy hydrated glow without the use of any shimmer or glitter. It layers perfectly under other skin care and absorbs really easily and feels like nothing but preforms like everything. A little goes a long way so it’s worth the cost. HIGHLY HIGHLY recommend! This is instant gratification for anyone who wants healthy, plump, glowy, hydrated skin! UPDATE: After trying other hydrating products (because I like trying different things) this is the one I ALWAYS come back to, especially when it needs an extra boost of hydration. I noticed it really helps plump up lines/wrinkles especially on “tech neck” or reading neck in my case. I also like using it on my arms on the fine lines that happen from holding a book so often and I even use it on my bikini line to help hydrate and heal any razor burn. I also apply it on and around the lips for an extra burst of plumping hydration and it works amazingly well! I will definitely repurchase, but after 9 months I still have about a quarter left. I hope this product is never discontinued. CANNOT RECOMMEND ENOUGH! On the fence? Just buy it! So far I’ve loved everything from Experiment Beauty (I think I’ve tried it all except for the lip balm)!

Love this product. Definitely gives you hydrated skin. My teenage son & I fight over mine. It actually helped repair his skin barrier. It has a sticky texture at first but absorbs quickly into the skin. Great serum!!!

This serum has been a game changer for tolerating my tretinoin. So moisturizing and soothing! I have used both day and night and it’s not heavy at all, which can be an issue for me with many serums/moisturizer, not greasy at all and soaked in nicely. Also, you could up the anti by using experiments reusable facemask, really locks it in nicely. Have an awesome glow and do we finish to the skin afterwards. Quickly turning into a holy girl item for me.

Better than hyaluronic acid! This 30% glycerin serum will leave your skin glowy and moisturized! I’ve been using this for a few years now and always repurchased it! If you have dry, sensitive skin, this serum will save your skin! 10/10 recommend!

I live in a drier state and I am in my mid 40s. I'm Very careful about keeping my skin moisturized to minimize aging . I really love this product. I layer it at the end of my serums but before my moisturizer.

I am new to this product, new to this company. Item came unsealed, undated. Torn box, opened product. What a waste of money. Would give zero stars if could. Will not purchase from this company again. What's going on in today's world, when people spend hard earned money in good faith and get such poor quality control. Shame on you, Experiment Beauty. Shame on you, Amazon.

I'm a big fan of Experiment's products but I probably won't be repurchasing this one. It is very hydrating, even with dry skin I could almost wear this alone, but it's soooo sticky. This is reserved for nighttime use for me.

Very good gel, it keeps my skin moisturised for the whole day.
