    It’s hard to pick my fav EH product but this up there!

    PSA for women over 40. You NEED this. I could literally see a difference in 2 days when I ran out and had to wait for my new jar of this magic to arrive. It plumps your skin, fills in lines and just overall makes my skin feel amazing. You need this, the Siren Silk, and the Isla eye serum as non-negotiables. I use others from EH I love too like Marina serum and washes, etc, and they’re all frankly amazing. But if I don’t have those three products my skin looks tired, fine lined and just not as youthful.

    Favorite Moisturizer from EH

    This is my favorite moisturizer they make. It leaves my skin with an instant glow. It's not a standard moisturizer as it is thick but it makes my skin look amazing. It also smells nice.

    Mermaid Moon

    I’m loving this balm! I alternate between the Mermaid moon and the Nymph Necter at night and I just love how baby soft it makes my skin feel ! I also use it on my neck and chest. Thank you Earth Harbor!

    Great!

    Keep this product out of the heat! By the time it was sent to me in South Georgia, the ingredients were separated. It’s been a little hard to get them to remix. Love the product itself though!
