Seaweed Peptides naturally retain moisture and can facilitate the function of skin cells and their repair, build collagen and elastin, and keep fine lines, wrinkles and sagging at bay. They scavenge free radicals and decrease discoloration, leaving your skin looking and feeling more buoyant, even-toned, smooth and soft.  

Crosslinked Sodium Hyaluronate and Botanical Hyaluronic Acid potently hydrate and improve skin's elasticity. Through biomimicry, they effectively penetrate deeply into skin for maximum hydration while helping to tighten pores, fill in fine lines and wrinkles, and combat flaccid skin.

Niacinamide is a skin-repairing B3 vitamin that improves the appearance of enlarged pores, uneven skin tone, fine lines and wrinkles, acne, dullness, and skin firmness.  

Pomegranate Fruit Powder is a superfruit rich in antioxidants, vitamin C, vitamin B5, and vitamin E. It attracts and holds in moisture, lending itself to skin plumping and lifting. Pomegranate Fruit also helps reduce redness and brightens complexion while balancing skin.  

Aloe Leaf Juice is lightweight, hydrating and soothing. Aloe's natural salicylic acid (BHA) makes it an effective way to naturally prevent blemishes and restore skin. It also improves skin’s clarity + texture by smoothing and brightening dark spots.  

Blue Yarrow, from the flowering Yarrow plant, is a soft blue oil that helps rejuvenate rough, irritated, and reddened skin.  

Pomegranate Seed Oil is brimming with essential fatty acids, antioxidants, anti-inflammatories, vitamins B5 + C + E, polyphenols, tannins, minerals and other nutrients crucial for healthy, glowing skin. It helps protect skin against environmental damage and leaves skin looking supple and youthful.
Shake to activate. Apply 4-10 drops to clean skin and massage in as a leave-on treatment. Include any place on your body needing a refreshing hydration boost. Use daily for maximum results.

    Plumping and smoothing

    Celestine is by far the best hydrating and plumping serum I’ve ever used! Immediately after my first use of this silky serum the fine lines on my forehead were instantly plumped and diminished. With daily use in the a.m. I’m seeing even greater results with each passing day and the serum feels absolutely velvety going on while acting as a great base under my liquid foundation on makeup days. My favorite way to use Celestine is to mix in just a few drops of Calypso with it before applying and then watch my fine lines disappear with the added benefit of a beautiful glow that is never oily from the Calypso Elixir. I follow up with Mermaid Milk moisturizer and Eclipse SPF in the mornings and most days I don’t wear any makeup because my skin looks and feels radiant, smooth and dewy all day long. If you’ve ever wondered whether Celestine lives up to its claims, I can assure you it definitely does. I just purchased two more bottles so I’ll never be without this new staple serum in my Earth Harbor skincare routine!

    Miss it!

    I really love this serum for hydration and the peptides. I belong to 2 beauty box subscriptions, and a few weeks ago, received a deluxe sample of a highly rated HA serum, so I switched to that to give it a go. It's hydrating, though sticky. The kicker was when I noticed that my skin was beginning to look less plump. I now know that I need this as part of my routine. Sometimes I will cocktail it, but I ALWAYS use an essence prior to applying, and put one or two drops on while my skin is still damp. Sometime I'll mist on some extra Essence when it doesn't seem to be absorbing as quickly as normal. It works wonderful that way. I make sure I wait until it has been fully absorbed before adding an additional serum, such as a retinopathy. Needless to say, I will be returning to Celestine and purchase a new bottle soon.
