ALASTIN Skincare HA IMMERSE Serum Pro 4.0 fl oz / 118.3 mL – Professional Size Hyaluronic Acid Facial Serum

ALASTIN Skincare HA IMMERSE Serum Pro, a professional-size hyaluronic acid facial serum.

HA IMMERSE is formulated to provide both immediate and lasting hydration while helping skin look smoother, plumper and more radiant. ALASTIN states that the formula uses high-molecular-weight hyaluronic acid and proprietary Octapeptide-45 to support the skin's natural hyaluronic acid production.

This 4.0 fl oz / 118.3 mL professional-size format is substantially larger than the brand's standard 1.0 fl oz retail size. Professional-size listings identify the 4 oz format as a professional/back-bar product.
