HA (Hyaluronic Acid) IMMERSE Serum™

$122.00

1 fl oz / 29.6 mL

A hydrating serum that works on two timelines. Crosslinked hyaluronic acid holds water at the surface for an immediate, smoother feel, while proprietary Octapeptide-45 supports the skin’s own high-molecular-weight hyaluronic acid over time. It goes on first after cleansing, before other serums, and complements dermal fillers.

Why Dr. Howarth recommends it
Stocked as the hydration layer under the Restorative Skin Complex when a plan needs water without weight. ALASTIN formulates it to complement injectable hyaluronic acid, which suits patients who visit Aesthetica for filler.
  • Boosts surface hydration for smoother-looking skin
  • Supports the skin’s own hyaluronic acid over time
  • Helps minimize the look of fine lines
  • Complements dermal fillers

Apply 1–2 pumps morning and evening as the first product after cleansing, before other serums and moisturizer. It may also be used on the neck and décolleté. Avoid the eyes; if contact occurs, rinse thoroughly with water.

  • Octapeptide-45: helps the skin increase its own high-molecular hyaluronic acid
  • Sodium Hyaluronate Crosspolymer: crosslinked HA that holds water at the skin’s surface
  • Hexapeptide-11: helps preserve the skin’s natural HA from enzyme breakdown
