Alastin HA (Hyaluronic Acid) IMMERSE Serum in a convenient 15ml travel size — TSA-compliant and ideal for travel, post-procedure kits, or trialing the formula before committing to the full size. Delivers the same physician-developed, instant-and-long-term dual hydration system as the full 1oz version, providing immediate surface plumping while actively building the skin's capacity to retain its own hyaluronic acid over time.

Multi-weight Hyaluronic Acid delivers instant hydration and surface smoothing across multiple skin depths simultaneously. Hydroxymethoxyphenyl Decanone — a potent antioxidant unique to Alastin's formulas — not only provides antioxidant protection but actively boosts the skin's natural hyaluronic acid production pathways, creating a long-term hydration benefit that improves with continued use. Silver Mushroom (Tremella Fuciformis) provides hydration with significantly more water-binding capacity than standard hyaluronic acid. The lightweight serum texture absorbs immediately and is suitable for all skin types — layering cleanly under moisturizer, SPF, and makeup without pilling or interference.

Apply to cleansed face and neck before moisturizer, morning and evening. Non-comedogenic, hypoallergenic. Available at Beauty Riche — authorized Alastin retailer with same-day shipping.
