The hydration serum your skin keeps drinking, long after you've stopped applying.
Alastin HA Immerse Serum delivers instant glassy hydration with a crosslinked sodium hyaluronate that holds 50× more water than standard HA, plus peptides that train your skin to produce its own high-molecular hyaluronic acid over time. Winner of the 2022 Oprah Daily O-Award for Best Hydrating Serum.
Why people reach for it
Crosslinked HA delivers immediate plumping; peptides build your skin's own HA over weeks of consistent use.
Watering the skin softens the look of fine lines that show up when skin is thirsty — and smooths overall texture.
Skin reads visibly more radiant within minutes. 98% of study participants agreed HA Immerse made skin feel smooth immediately.
No pilling, no stickiness — engineered to layer under serums, retinols, moisturizers, and SPF.
Who it's for
All skin types, including sensitive — designed to address:
Why it works
A crosslinked hyaluronic acid that holds 50× more water than standard HA — instant, deep, sustained hydration.
A peptide that supports your skin's natural ability to produce its own high-molecular hyaluronic acid over time.
Helps prevent the production of enzymes that break down HA in the skin — protects the hydration you build.
A botanical hydrator that holds water against the skin even more effectively than hyaluronic acid alone.

Common questions
How is HA Immerse different from a $20 hyaluronic acid serum?
Two big things: crosslinked HA (holds 50× more water than standard HA) and the peptide system (Octapeptide-45 + Hexapeptide-11) that helps your skin make its own HA over time. Most drugstore HA serums use a single uncrosslinked form and skip the peptides entirely.
Should I apply on damp or dry skin?
Slightly damp gives the best result — HA pulls moisture from whatever's nearby, so applying to damp skin lets it pull from the water on your face rather than the air.
Can I use it with retinol or vitamin C?
Yes — apply HA Immerse first on clean, slightly damp skin, then layer your actives on top. The hydration buffer often helps people tolerate stronger retinoids better.
Does it cause pilling or stickiness?
No. The formula was specifically engineered to layer cleanly with other actives, sunscreen, and makeup.
Is there a dupe for HA Immerse?
The crosslinked HA + peptide combination is hard to replicate. Most alternatives use a single form of HA and lack the long-term peptide support.
How long does the bottle last?
Roughly 2 months at one pump twice daily, or 1 month at the full two-pump protocol.
