Alastin HA Immerse Serum

It delivers instant, lightweight hydration to the skin's surface for a smoother, plumper, more radiant look, while its proprietary Octapeptide-45 helps your skin naturally boost its own high-molecular hyaluronic acid for long-term plumping and hydration benefits.

It's an excellent choice. Unlike many HA serums that only hydrate the surface, HA Immerse also helps your skin produce its own hyaluronic acid deep within, so it tackles both immediate dryness and longer-term dehydration. In clinical use, 98% of participants felt smoother skin immediately and 91% reported replenished moisture after four weeks.

After cleansing, apply 1–2 pumps to your face and neck as the very first product in your routine, morning and evening. Follow with your other serums, treatments, moisturiser and, in the morning, sunscreen.

Yes, HA Immerse can be used safely on the neck and décolleté. It has not been tested directly on the eyes or eyelids, so avoid the immediate eye area and check with your practitioner if you're unsure.

It depends on your skin type and the season. HA Immerse is a hydrating serum rather than a moisturiser, so drier skin or colder months may still call for a moisturiser layered on top. Your skincare professional can advise on the right pairing for you.

Hydration is immediate — 98% of participants felt smoother skin straight after applying. The deeper plumping and radiance benefits build with consistent twice-daily use, with most reporting visibly improved moisture and overall appearance within four weeks.
