Tarte Mermaid Skin Hyaluronic H2O serum

I’m a big advocate of trying samples and using it all up before purchasing the full size version when it comes to skincare products. I have been in the market for a new type of hydrating serum so when I read the name “Mermaid Skin,” I thought that this would be right up my alley so I picked up this serum from Sephora. Here are my thoughts:


According to the Sephora website

-Hyaluronic Acid: Naturally-occurring ingredient in the human body which delivers moisture, firmness, and suppleness.
-Vitamin B5: Hydrates and soothes.
-Algae and Marine Extracts: Help reduce the appearance of fine lines and wrinkles while smoothing and softening skin.

Water, Hydroxyethylcellulose, Sodium Hyaluronate, Disodium EDTA, Sodium Nitrate, Algae Extract, Calcium Pantothenate, Glycerin, Phenoxyethanol.

what it claims to do

This powerful serum splashes skin with intense moisture without feeling greasy, heavy, or sticky for plump, dewy skin. The completely clear formula is loaded with complexion quenchers like hyaluronic acid, vitamin B5, and marine plant extracts to help provide powerful antioxidant defense. 


For the sample, at least, the serum comes in a small tube with a pump closure. The color is a bright ocean blue that I think is consistent with the mermaid and water theme that reminds you that this product will bring on the hydration. Each pump gives me about one drop of serum which I find useful because a drop or two is the perfect amount for me.



Here’s the thing - when I first started using this, I did not notice anything different about my skin. I seriously wondered if it was doing anything at all because I couldn’t feel anything. I tried it on its own, mixed in with lotion, everything. I stopped using this after a while because I didn’t see the point but THAT was when I noticed a change in my skin that made me realize that Tarte’s Mermaid Skin serum perhaps had an effect on my skin after all. I learned that apparently hyaluronic acid attracts moisture and when used correctly, can pull moisture from your skin. I realized that my lotions and moisturizers went a LOT further when I used this serum as opposed to before.



While I got this sample of the serum for free, the full priced version comes in a 1.07 oz bottle that sells for $42. I’m not sure if I would repurchase this right away but as I can see this coming in very handy in the winter, I may buy it.
