Alastin HA IMMERSE Serum

$158.00

A replenishing serum that restores hydration, smooths texture, and supports the skin barrier.

This is hydration on another level. It gives skin that instant plumped, dewy look while also training it to make more of its own hyaluronic acid over time. The texture is silky and layers perfectly under moisturizer or SPF, making it a versatile daily essential. We love it for restoring bounce, smoothing fine lines, and keeping skin supple and resilient.

Alastin HA IMMERSE Serum is a breakthrough daily hydrating serum that delivers both immediate and long-lasting results. Formulated with high- and low-molecular-weight hyaluronic acid, it provides instant plumping hydration while supporting the skin’s own ability to increase natural hyaluronic acid levels over time. Powered by Alastin’s proprietary Octapeptide-45 and TriHex Technology®, it helps clear out damaged collagen and elastin while promoting new, healthy fibers. Antioxidants and botanicals like Tremella Fuciformis (Silver Mushroom) add extra hydration and protection. The result is skin that looks smoother, feels softer, and appears more youthful and resilient.

Press into face, neck, and décolleté; follow with moisturizer to seal in water. Allow a full minute for absorption before the next step. Use morning and evening when possible, and pair daytime routines with SPF. Treat this as a small daily ritual—slow the breath, soften the jaw, and let the skin receive.

Frequently Asked Questions

Is Alastin HA IMMERSE Serum good for dry or sensitive skin?
Yes. Alastin HA IMMERSE Serum is formulated to replenish hydration and support the skin barrier, which directly addresses dryness and helps reduce texture issues. It is a hyaluronic acid-based replenishing serum that attracts and holds moisture in the skin while smoothing surface texture, and its professional-grade formulation is intended to be gentle enough for normal to sensitive skin types. People who benefit most are those with dehydration lines, reactive or easily irritated skin, and anyone looking to strengthen a compromised barrier. As a limitation, extremely dry skin may still require a richer cream layered on top for overnight barrier repair, and anyone with active dermatitis should consult their clinician before adding a new serum.
How should I layer Alastin HA IMMERSE Serum with retinol, vitamin C, and moisturizers?
Use Alastin HA IMMERSE Serum after cleansing and any lightweight watery toners, but before thicker serums and creams. Hyaluronic acid is a humectant that works best on slightly damp skin to draw in moisture, so apply it first to help plump and hydrate the skin, then follow with active serums like vitamin C or retinol once the product has absorbed. This layering preserves the serum’s hydrating function and lets stronger actives penetrate effectively. Users combining multiple actives benefit most when they maintain gentle layering and introduce products gradually to monitor tolerance. As a practical note, if you experience irritation when pairing potent actives, alternate nights or consult your clinician to create a tailored routine.
How long before I see results from Alastin HA IMMERSE Serum?
You may notice immediate improvements in skin hydration and a smoother feel within hours, while more visible texture and fine line improvements typically appear with consistent use over several weeks. Hyaluronic acid provides quick plumping by attracting water, which reduces the appearance of superficial lines right away; sustained barrier support and improved skin surface quality develop over regular daily use, often within four to eight weeks. This product is most effective for people with dehydration, early signs of aging, or rough texture. As a limitation, deeper wrinkles and structural volume loss usually require longer-term interventions or in-office procedures for significant change.
Can I use Alastin HA IMMERSE Serum after professional treatments like laser or microneedling?
Yes, this serum is often appropriate after procedures once your clinician clears you, because its hydrating and barrier-supporting properties help soothe and restore treated skin. Topical hyaluronic acid helps replenish moisture, reduce transepidermal water loss, and create a supportive environment for barrier recovery; medical-grade formulations are commonly recommended in post-procedure protocols for their purity and tolerability. Patients who benefit most are those recovering from resurfacing treatments, microneedling, or lasers who need non-irritating hydration. Do not apply it immediately to open wounds or actively bleeding areas, and always follow your treating clinician’s timeline for reintroducing products to avoid irritation or infection.
How does Alastin HA IMMERSE Serum differ from regular hyaluronic serums?
Alastin HA IMMERSE Serum differs by being a medical-grade replenishing formulation designed with a clinical focus on hydration, texture smoothing, and barrier support rather than only temporary surface plumping. It emphasizes restoring moisture and supporting the skin barrier to improve surface texture, and its formulation targets both immediate hydration and ongoing barrier health. Shoppers seeking professional-grade, clinically oriented skincare to address dehydration, early lines, and rough texture will likely see more utility than with basic over-the-counter hyaluronic gels. For transparency, differences vary by ingredient concentrations and supporting clinical data, so review product ingredient lists and your clinician’s guidance when comparing options.
