Alastin HA IMMERSE Serum

$158.00

A replenishing serum that restores hydration, smooths texture, and supports the skin barrier.

This is hydration on another level. It gives skin that instant plumped, dewy look while also training it to make more of its own hyaluronic acid over time. The texture is silky and layers perfectly under moisturizer or SPF, making it a versatile daily essential. We love it for restoring bounce, smoothing fine lines, and keeping skin supple and resilient.

Alastin HA IMMERSE Serum is a breakthrough daily hydrating serum that delivers both immediate and long-lasting results. Formulated with high- and low-molecular-weight hyaluronic acid, it provides instant plumping hydration while supporting the skin’s own ability to increase natural hyaluronic acid levels over time. Powered by Alastin’s proprietary Octapeptide-45 and TriHex Technology®, it helps clear out damaged collagen and elastin while promoting new, healthy fibers. Antioxidants and botanicals like Tremella Fuciformis (Silver Mushroom) add extra hydration and protection. The result is skin that looks smoother, feels softer, and appears more youthful and resilient.

Press into face, neck, and décolleté; follow with moisturizer to seal in water. Allow a full minute for absorption before the next step. Use morning and evening when possible, and pair daytime routines with SPF. Treat this as a small daily ritual—slow the breath, soften the jaw, and let the skin receive.
