Minimal and moisturizing, infused with hyaluronic acid (HA), Neptune absorbs instantly, infusing thirsty skin with hydration. As a serum, it works in tandem with your moisturizer, increasing the skin’s capacity to lock in hydration without any heavy, greasy feeling.

Formulated with a 1% high-molecular-weight hyaluronic acid, Neptune draws moisture in right where it’s needed. Combined with elegant, antioxidant-infused botanicals like butterfly pea, green tea, and helichrysum, it smooths, plumps, and hydrates while reinforcing the skin’s natural barrier against harmful environmental factors.

The first ever ocean-blue Hyaluronic Acid serum, apply Neptune under make-up or go without for the matte-blurred glass skin effect.

Fragrance-free, clinically tested, and dermatologist approved.

✹ Antioxidant formula reinforces the skin’s barrier against free radicals
✹ 1% high-molecular weight HA provides the best support, according to science
✹ Vegan and cruelty-free—Leaping Bunny certified
✹ Works on all skin types (soothes, heals, brightens plumps, hydrates, nourishes, and protects)

Used the hyaluronic serum and I loved it!! Didn’t dry out my skin and lasted a long time! You only need a small pump - also ingredients are super clean which I love!

My skin has never felt so smooth & subtle. Fine lines have been reduced, and nearing my 44th birthday, I look like I'm still in my 30's. I find I only need a little bit everyday, and the serum gets the job done, nicely. Highly recommend!


Luna Nectar

Thank you Sokhna for your review. We hope you've had the chance to try it, would love to hear your feedback!

Hyaluronic acid serums create a moisture lock over the skin, resulting in a blurred, matte finish. Ours is infused with antioxidants helichysum, butterfly pea flower, and green tea as well to also protect the skin against free radicals. Contrary to many other hyaluronic acid serums that include a combination of different low molecular weight versions in greater than 1% ratios, ours is high molecular weight at 1% to best support the skin according to scientific studies.

After cleansing, apply 1-2 pumps to wet skin. Follow up with facial oil or cream to lock hydration. For a matte effect, apply serum as last step over facial oil.

Full list of ingredients:

Aqua, Helichrysum Arenarium (Helichrysum) Hydrosol Water*, Camellia Sinensis (Green Tea) Hydrosol Water* (infused with Clitoria Ternatea (Butterfly Pea Flowers)), Lactobacillus Ferment, Vegan Sodium Hyaluronate (Hyaluronic Acid), Tetrasodium Glutamate Diacetate, Citric Acid
* Certified Organic
