ALASTIN HA IMMERSE Serum is a lightweight hyaluronic acid serum that goes beyond surface-level hydration by helping your skin rebuild its own HA reserves from within. Most hyaluronic acid serums sit on top of the skin and evaporate. This one uses a proprietary peptide complex and high-molecular-weight sodium hyaluronate to deliver immediate smoothing while signaling your skin to produce more of its own hyaluronic acid over time. The result is plumper, more hydrated skin that actually holds onto moisture, not just borrows it. In clinical testing, 98% of participants agreed their skin felt smooth immediately after application, and 91% reported improved moisture and overall skin appearance after four weeks of use. Winner of both the New Beauty "Best Hyaluronic Acid" award and Oprah Daily's 2022 O-ward for "Best Hydrating Serum."
Instant Surface Hydration That Lasts: Sodium hyaluronate crosspolymer binds up to 50 times more water than standard hyaluronic acid, locking moisture at the skin's surface for immediate smoothing without a tacky finish.
Long-Term HA Production From Within: Proprietary Octapeptide-45 supports your skin's ability to naturally increase its own high-molecular-weight hyaluronic acid production deep within the dermis, delivering plumping and anti-aging benefits that build over time.
Protection Against HA Breakdown: Hexapeptide-11 helps prevent the production of enzymes that degrade your skin's existing hyaluronic acid, so the moisture your skin makes actually stays put.
Multi-Pathway HA Boosting: A natural sugar complex of xylitylglucoside, anhydroxylitol, and xylitol enhances your skin's own HA synthesis through a separate pathway, while hydroxymethoxyphenyl decanone acts as an intrinsic HA booster with added antioxidant protection.
Filler-Friendly Hydration: Formulated to complement dermal filler treatments, helping maintain skin plumpness and hydration between appointments.
-
If your skin feels perpetually thirsty, looks flat or crepey, or shows fine lines that seem to deepen throughout the day, this serum addresses the root cause: declining hyaluronic acid levels. It works well for all skin types, including sensitive skin, because the high-molecular-weight HA avoids the irritation and inflammation that smaller HA molecules can trigger.
This is also an excellent choice if you've had dermal filler treatments and want to support skin hydration and plumpness between appointments. Whether you're dealing with early fine lines or more advanced volume loss, the dual approach of instant moisture plus long-term HA rebuilding makes this serum a strong foundation for any anti-aging routine.
-
Apply HA IMMERSE Serum to slightly damp skin right after cleansing. The crosslinked hyaluronic acid binds water on contact, so giving it a thin layer of moisture to grab onto helps maximize the immediate plumping and smoothing effect before you layer the rest of your routine on top.
-
Apply: Dispense 1-2 pumps and smooth over clean skin morning and evening.
Technique: Apply as the first product in your routine after cleansing, before any other serums, moisturizers, or sunscreen. Avoid the eye area. If contact occurs, rinse thoroughly with water.
Frequency: Use twice daily for best results. Consistent daily use supports long-term hyaluronic acid production over time.

What makes ALASTIN HA IMMERSE Serum different from other hyaluronic acid serums?
Most HA serums provide only surface-level hydration that evaporates over time. ALASTIN HA IMMERSE Serum uses proprietary Octapeptide-45 and a natural sugar complex to stimulate your skin's own high-molecular-weight hyaluronic acid production. It also contains hexapeptide-11 to protect existing HA from enzymatic breakdown, so you get both immediate and long-term hydration benefits.
Will ALASTIN HA IMMERSE Serum feel sticky or tacky on my skin?
No. Despite its powerful water-binding ingredients, the formula is designed to feel lightweight and non-tacky. The sodium hyaluronate crosspolymer delivers hydration without the heavy or sticky residue that many HA serums leave behind, making it comfortable to layer under other products.
Can I use ALASTIN HA IMMERSE Serum with dermal fillers?
Yes. This serum was specifically formulated to complement dermal filler treatments. It helps maintain skin hydration and plumpness between filler appointments by supporting your skin's natural HA levels. Follow your provider's post-procedure timeline for when to resume your skincare routine.
Where does ALASTIN HA IMMERSE Serum go in my routine?
Apply it as the very first product after cleansing, both morning and evening. Because it is a lightweight serum, it should go on before any heavier serums, moisturizers, or sunscreen so the active peptides and hyaluronic acid can make direct contact with your skin.
Is ALASTIN HA IMMERSE Serum safe for sensitive skin?
Yes. The formula uses high-molecular-weight hyaluronic acid, which is less likely to trigger irritation or inflammation compared to low-molecular-weight HA. It is also fragrance-free. If you have specific sensitivities or reactive skin, reach out for a free skincare consultation before purchasing.
How long does it take to see results from ALASTIN HA IMMERSE Serum?
You can expect to feel smoother, more hydrated skin immediately after the first application. In clinical studies, 98% of participants agreed their skin felt smooth within 15 minutes. For long-term improvements in moisture retention, fine lines, and overall skin appearance, most participants reported noticeable results at the four-week mark.
Can I use ALASTIN HA IMMERSE Serum with retinol or exfoliating acids?
Yes. Because it is a hydrating serum without exfoliating actives, it pairs well with retinol, glycolic acid, and other treatments. Apply HA IMMERSE first on clean skin, then follow with your treatment products. The added hydration can actually help buffer some of the dryness that retinol or acids may cause.
