Alastin HA (Hyaluronic Acid) IMMERSE Serum™ is an award-winning anti-ageing hydrating serum that delivers both immediate and long-term skin transformation through its innovative dual-action approach to hydration. Formulated exclusively with high-molecular weight hyaluronic acid and the breakthrough peptide Octapeptide-45, this physician-dispensed serum provides instant moisture whilst simultaneously stimulating the skin's natural ability to produce its own hyaluronic acid for sustained plumping and anti-ageing benefits. The elegant formulation features Sodium Hyaluronate Crosspolymer, which possesses 50 times more water-binding capabilities than standard hyaluronic acid, alongside Silver Mushroom Extract (Tremella Fuciformis) and Hexapeptide-11 to prevent HA degradation and encourage continuous skin hydration.
 
This lightweight, fast-absorbing serum is suitable for all skin types including sensitive, dry, oily, and acne-prone skin. The fragrance-free formula layers seamlessly under makeup and other skincare products, making it an essential first step in any professional skincare regimen, whilst its gentle yet effective formulation makes it ideal for post-procedure care and for soothing skin experiencing retinoid dermatitis or over-exfoliation.
