Does not work well with layering other products

I have dry skin so this may not apply to you if your skin is normal or combination skin.I really wanted to love this product. I tried it on the back of my hands in store before purchasing and it absorbed immediately. When I actually used it, I found that when I layered it with my other skin care products (serum, sunscreen, moisturizer), it was difficult to put other products on after. Its a bit tacky even if you a bit to settle, which on its own it absorbs immediately. Its not sticky or greasy, you just have to put double or triple amount of other steps that follow and that is a waste of money. When I tried this with sunscreen it made my face sunscreen difficult to smooth over my face. After my sunscreen dried there was obvious places on my face that had more sunscreen and when I tried to spread it, my sunscreen was pilling like crazy.I love the idea of a hyaluronic serum with few ingredients. I have very sensitive skin and this did not cause any irritation, stinging, or acne. I also love that there are few ingredients in this. « less

Fantastic for sensitive skin!

This is one of my all time favorite skincare items, and I've tried hundreds. I have mature, dry, sensitive, fair, reactive, allergic, eczema prone skin, and this serum hydrates and helps heal and prevent eczema flare ups. I love to layer as much hydration as possible, and this has a thin, watery, silky texture that absorbs quickly and doesn't leave any sticky residue. I like that it doesn't have silicones, because I try to use them at the end of my routine as they seal everything in, but prevents anything else from being fully absorbed. I've been using this since it was launched and could never be without. It has a simple but effective ingredients list that is probably safe for any skin type. It's also very affordable and does an amazing job at hydrating. I use it twice a day.

Helps with hydration - Season changing lifesaver

I bought this upon first release through the target website. I am absolutely in love and have seen an immediate improvement in the hydration of my skin. It has really help in the transition between winter to spring in this up and down Canadian weather. The serum sinks in so smoothly and quickly and has really helped with the small dry patches I get on my combination skin. Especially around my mouth and upper checks around my eyes. I think it has also help with my slight acne clearing redness and evening my skin tone. I love this product and will definitely be repurshing when I finish this bottle! I think it will be a year round product.

I’m a believer!

I got the mermaid skin/rainforest of the sea skincare set using my Sephora points months ago and they sat in my bathroom. I was using the same old skin care, but my skin was blotchy and tired. My wrinkles were showing all their glory and I remembered these beauties. I’ve been using the frixxxion stick, then the mermaid skin serum and topping it off with the h2o gel for only like a week now. Wow. My skin is glorious. Blemishes healed up and my forehead wrinkles are practically gone. Additionally, I’ve had this one pore on my forehead for YEARS that was huge. Only one awkward gross pore that refused to go away. It’s literally shrinking! I use the frixxxion stick in the mornings and a gentle cleanser before bed, and I’ve been using mermaid skin/h20 morning and night after cleansing.

Best Product Ever!

I love this product so much! I have used it twice a day for 5 months now and it still looks like I haven’t used any. I have dry skin and I loved the neutrogena hydro boost serum but it was pricey for the amount of product you get, I used it twice a day and was out in 3 months. So I actually bought this when I went into Sephora and it’s pretty cheap for the amount of product that you get. It helps provide moisture and helps prevent acne, and has also shrunk some of my pores. I love the tacky feeling of it and goes really well under a mosturizer. When I run out I will defiantly be buying more of it for sure!

You will feel and see a difference in your skin after a week! Apply after you wash your face and before you apply your moisturizer. I liked putting it on at night just so it could soak into my skin longer without anything else other than moisturizer on top of it.

Use this before your primer! My skin used to be the same way but since I started using this at the start of my makeup routine, my skin looks so hydrated!

Ok girls! As we all know it’s getting cold outside. My face/body gets super dry in the winter and won’t hold ANY moisture. What are some good skincare tips, routines or masks to help with that??

This has saved my skin’s life. I have very dry skin and any sort of foundation, concealer, powder, ANYTHING I put on my skin became dry and patchy. Use this before putting on your moisturizer and it really locks in the hydration. Now my skin is radiant and glowing year round!
