Alastin HA Immerse Serum

Alastin HA Immerse Serum
 
A breakthrough daily hydration serum that works on two levels simultaneously — delivering immediate, visible hydration to the skin's surface while supporting the skin's own long-term production of hyaluronic acid deep within. Formulated with high-molecular hyaluronic acid, proprietary Octapeptide-45, and a multi-layered humectant complex.
 
What sets this serum apart from conventional hyaluronic acid products is Octapeptide-45 — a proprietary peptide that helps the skin generate its own high-molecular HA intrinsically, rather than simply applying it topically. The result is both immediate plumping and a longer-term hydration benefit that builds over time.
 
Available at Epios Cosmetic Clinic — an authorised Alastin stockist in Paddington, Sydney. Australia-wide shipping available.
 
About Alastin HA Immerse Serum
Hyaluronic acid has become one of the most widely used ingredients in skincare — and with good reason. HA is a naturally occurring molecule in the skin that holds water, contributes to a plumped and hydrated appearance, and supports the structural integrity of the dermis. The challenge is that most HA serums work only at the surface level, providing a temporary hydrating effect that diminishes as the product wears off.
 
The Alastin HA Immerse Serum takes a different approach. Rather than relying solely on topical HA to deliver a surface hydrating effect, it combines multiple forms of hyaluronic acid with Octapeptide-45 — a proprietary peptide that has been shown to support the skin's own intrinsic production of high-molecular weight HA deep within the dermis. This dual mechanism means the serum delivers immediate visible hydration while also working to restore and support the skin's own long-term hydration capacity.
 
The result is a serum that feels immediately plumping and hydrating on application, and continues to support skin hydration levels with consistent daily use. It has received recognition as a favourite among dermatologists for its combination of immediate and long-term hydration benefits.
 
At Epios Cosmetic Clinic, we recommend the HA Immerse Serum as a first-step serum in a daily skincare routine — applied immediately after cleansing to draw moisture into the skin before layering actives and moisturiser. It is also particularly well suited for use alongside active treatments such as retinoids, where maintaining skin hydration and barrier integrity is a priority, and as a post-procedure hydration support following Rejuran, skinboosters, Morpheus8, and laser treatments.
 
Individual results vary. Consistent twice-daily use is recommended for best outcomes.
 
Key Ingredients
Octapeptide-45 (proprietary) -  The standout ingredient in the HA Immerse formula. A proprietary peptide that supports the skin's own intrinsic production of high-molecular weight hyaluronic acid deep within the dermis — providing long-term plumping, hydration, and anti-ageing benefits that build over time, rather than relying solely on topical application.
Hexapeptide-11 - Supports the skin's natural detoxification and repair processes, and acts as a humectant — attracting water to the upper layers of the skin to improve surface hydration.
Silver Mushroom Extract (Tremella fuciformis) - A natural humectant with water-binding properties comparable to hyaluronic acid, providing an additional layer of hydration support.
 
Free from: fragrance, parabens, sulphates. Suitable for all skin types including sensitive and reactive skin.
 
How to Use
Apply 1–2 pumps to the face and neck immediately after cleansing — before any other serums, actives, or moisturiser. Applying HA Immerse to slightly damp skin maximises the humectant effect and helps draw additional moisture into the skin. Avoid contact with the eyes.
 
Layer your remaining serums — such as the Alastin Restorative Skin Complex or Alastin A-LUMINATE Brightening Serum — over the top, followed by the Alastin Ultra Nourishing Moisturiser and SPF in the morning.
 
The HA Immerse Serum is lightweight enough to be used as a sole moisturiser for oily skin types in humid conditions. For very dry skin, layering a richer moisturiser over the top is recommended to lock in the hydration the serum delivers.
 
For post-procedure use following Rejuran, skinboosters, Morpheus8, or laser treatments at Epios, apply as directed by your treating doctor. The calming properties of high-molecular HA make it suitable for use on sensitised or post-procedure skin.
 
Who This Product Is Suitable For
The HA Immerse Serum is suitable for adults concerned with:
— Dehydrated or dry skin lacking visible plumpness and radiance
— Fine lines and surface wrinkles related to dehydration
— Skin barrier compromise — including those using retinoids, active treatments, or recovering from procedures
— Sensitive or reactive skin requiring a gentle, calming hydration formula
— General skin health maintenance as part of a daily anti-ageing routine
Because it uses high-molecular HA — which works at the skin's surface rather than penetrating deeply — it is exceptionally gentle and suitable for all skin types, including sensitive, rosacea-prone, and post-procedure skin. It is also oily-skin friendly and non-comedogenic.
 
It pairs well with every other product in the Alastin range and is recommended as the first step in a layered Alastin skincare regimen — applied before the Restorative Skin Complex, A-LUMINATE Brightening Serum, and Ultra Nourishing Moisturiser for a complete daily protocol.
