The Science of Hydration: Why Neptune Uses a Hydrosol Base
While Hyaluronic Acid is essential, Luna Nectar’s Neptune Hydrate & Blur Serum differentiates itself by building its foundation on potent hydrosols - the aromatic water left after steam-distilling botanicals.
Traditional serums are often based on plain water (Aqua), but Neptune uses a blend of:
- Helichrysum Hydrosol: Known for its exceptional soothing and anti-inflammatory properties, ideal for calming stressed or sensitive skin.
- Green Tea Hydrosol (infused with Butterfly Pea Flowers): Delivers powerful antioxidants and gives the serum its unique blue hue, which helps visibly neutralize redness.
This concentrated base ensures your skin receives not just hydration, but a calming, antioxidant-rich treatment with every application.

The "Blur" Effect Explained: Instant Flawless Finish

The "Blur Effect" in Neptune is achieved through hydration, calming, and subtle color neutralization - not silicones:
- Hydration Plumpness: Deep moisturization (from HA) fills skin cells, minimizing the appearance of fine lines and texture.
- Anti-Redness: The combination of Helichrysum and the blue hue of the Butterfly Pea Flowers works to visibly neutralize redness, evening out the complexion.
- Probiotic Balance: Lactobacillus Ferment supports a healthy barrier, reducing inflammation often associated with visible pores and uneven texture.
The result? A calmer, smoother canvas that looks naturally filtered and less reactive.
