I have been using this product for almost 5 years. Have tried others every now and then, and keep returning to this. My skin is very sensitive, and even completely "natural" products can irritate/redden/cause my skin to swell. This does not. This is VERY lightweight and I use it in the mornings under my tinted sunscreen. "Relaxing" peptides keep my slight wrinkles under my eyes relaxed, the hyalouronic acid keeps my skin plump and moist - without looking greasy - and the peptides work all day to promote collagen growth to keep my skin nice and smooth. I will be 50 this summer. Will use this product forever.

Love this product, I find my skin looks younger and feels firmer. I have been using this product about 3 years and highly satisfied. I first learned of this great product from a Spa that offers many different procedures for the skin and they include HydroPeptide as the preferred salon brand.

I use it as a first layer after cleansing . Can"t say for sure if it make any difference but hope it works in combination with moisturizer and face oil.

After hundreds if not thousands of dollars spent on high end products, I finally found my Holy Grail. I'm 61 yrs old, with combination skin, pores the size of the Grand Canyon, skin that still breaks-out, skin with fine lines and wrinkles, and the horrible sagging neck. After reading the reviews for HydroPeptide products, I decided to give the Power Serum a try first. (Look at the ingredients...it's loaded with great things...and no parabens!!!). After cleansing my face with my Clarisonic, I applied the Power Serum. It absorbs instantly into my combination skin. It doesn't leave a greasy feeling. It doesn't clog my pores or cause any acne. Alone, this serum improved the creppiness under my eyes and diminished crows feet. It also seems to be toning my neck. After 1 month of positive results, I decided to also try the Stem Cell Serum and the Ultra Light Moisturizer. WOW!!! The best effects ever!!! I mix 1 squirt of the Power Serum with 1 squirt of the Stem Cell Serum in my palm, rub my palms together to mix it all up (a facial cocktail), and then massage it into my face and neck. Wonderful!!! Then I follow with 1 squirt of the Ultra Light Moisturizer with just a few drops of water and massage that into my face and neck. Just the best!!! These 3 products do not cause any breakouts, no greasiness, no clogged pores. I do this morning and night. My face looks much younger, toned, and clear. I was visiting out-of-state friends a few weeks ago, and everyone was complimenting me on my skin. At a lovely tea, some of the ladies didn't know my age and were shocked when I told them that I was 61. They all thought I was in my late 40s or early 50s. OMG!!! I'll take those years!!! Yes, the products are a bit expensive, but after all the $$$ I've wasted on products that don't work or have caused acne and clogged pores, I feel that this is a real bargain. No, this isn't an invasive face lift, but it's doing 100% better than any other product I've tried. Also, I received a free sample of the Advanced Ultra Rich Moisturizer with my last purchase. That will be my next purchase when my sample is used. I'm using that around my eyes. I'm going to start my husband on these products!!!

Received a sample of this and came back to purchase. It's loaded with peptides and does tighten a bit. Instead of my usual daytime Vit C serum, I'll substitute this a few days. In the evening, instead of RetinA, I'll alternate with this.I love it on the neck too. It's drying, so extremely dry skin beware.All in all a good product for aging skin.

I am really skepical about products that claim to make you look younger. I met an esthetican and she recommended this brand. I started using this, and my 40+ year old skin looked dramatically firmer, and significantly more youthful. I actually got compliments on how great I looked (everyone thought I lost weight :)). Make up stayed on my skin better and did not soak in. I am hooked and won't give this up - Ever!

this product was recomended by my beautician. I have been using it for over two month with instant visible results. My skin feels absolutely smooth, with perfect texture. Definitely regained elasticity. Color is even, oily areas completely eliminated. It also works great as a base for make up. I am more than happy with this serum and can highly recomend it to all ladies.

I'm 57 with combination skin which I have always taken care of. I'm definitely a product junkie and was concerned about the cost of this product and whether it would do what it says. I've used it now for just over a week and have noticed an improvement in skin texture, smoothness and skin does look more dewy and glowing. Product really feels like it's working and I love the warm tingly sensation on my skin and a feeling of the skin tightening especially on my neck area. Feels especially good when using after exfoliating my skin. So far so good.

I have tried every antiaging cream out there and most have done something but I wasn't totally impressed. I was still searching for the ultimate product. I tried Hydropeptide serum and will never search for a product again. I LOVE it. It feels great, applies great with my makeup and has an immediate lifting feeling. I get comments all the time on how good my skin looks. I used to get a little break out every month too but I think its helped clear that too. Its just so good for my skin.

What a waste of money don't believe all the 5 stars.
