ALASTIN Skincare® HA (Hyaluronic Acid) Immerse Serum is an advanced hydrating treatment designed to deliver immediate moisture while supporting the skin’s natural ability to maintain long-term hydration. This award-winning serum helps visibly smooth fine lines and improve skin texture, revealing a more radiant and youthful-looking complexion with continued use.

At the heart of the formula is proprietary Octapeptide-45, an innovative ingredient that helps stimulate the skin’s natural production of high-molecular-weight hyaluronic acid. Combined with topical hyaluronic acid, this approach provides both instant surface hydration and deeper, longer-lasting plumping benefits. Skin appears smoother, more supple, and refreshed as hydration levels improve over time.

The lightweight, fast-absorbing serum layers seamlessly into any skincare routine and works well alongside professional treatments or dermal fillers to help maintain a hydrated, revitalized appearance. Suitable for all skin types, the formula delivers powerful hydration without feeling heavy or greasy.

Recognized by beauty experts and award panels for its performance, HA Immerse Serum helps transform dull, dehydrated skin into a complexion that looks smoother, firmer, and more luminous. ALASTIN Skincare® HA Immerse Serum is an essential daily step for anyone seeking lasting hydration and visibly healthier, rejuvenated skin.
