ALASTIN Skincare Hyaluronic Acid HA IMMERSE Moisturizing Face Serum 1 oz — Lightweight Hydration & Peptide-Boosted HA

ALASTIN Hyaluronic Acid HA IMMERSE is a moisturizing face serum that delivers immediate surface hydration and supports your skin's natural ability to build its own hyaluronic acid over time.

This lightweight 1 oz restorative serum combines multiple hyaluronic acid forms with ALASTIN’s proprietary Octapeptide-45 to give skin instant smoothing benefits while helping increase the skin’s long-term hyaluronic acid levels. Designed for daily use and compatible with dermal fillers, the formula aims to minimize the appearance of fine lines and improve radiance without clogging pores. It’s suitable for layering under moisturizer and makeup and formulated to be non-comedogenic and hypoallergenic.

How quickly will I notice hydration and smoother texture?

Many users experience immediate surface hydration and a visible smoothing effect after the first application thanks to multiple molecular weights of hyaluronic acid that sit at different skin levels. Continued use supports the skin’s own hyaluronic acid production, which can enhance plumping and reduce the visual depth of fine lines over time.

• Instant moisture boost at the skin surface for softer touch.
• Short-term plumping from low- and medium-weight hyaluronic acids.
• Long-term improvement driven by Octapeptide-45 stimulating endogenous HA.

What makes this serum different from other hyaluronic acid products?

Rather than relying solely on topical hyaluronic acid, HA IMMERSE pairs immediate-acting HA with Octapeptide-45, a peptide that helps the skin increase its own high-molecular-weight hyaluronic acid production. That combination offers both fast results and a mechanism intended to support lasting hydration and resilience.

• Proprietary Octapeptide-45 helps boost natural HA synthesis.
• Multiple HA sizes provide layered hydration benefits.
• Non-comedogenic formula that complements injectables and daily routines.

How should I use this serum in my skincare routine for best results?

Apply a few drops to clean, slightly damp skin morning and evening before moisturizer to lock in hydration. It layers well under sunscreen and makeup and can be used alongside other actives; patch testing when combining with potent exfoliants or retinoids is recommended.

• Use 1–2 pumps or drops on damp skin for optimal absorption.
• Follow with moisturizer and sunscreen during daytime use.
• Safe to use with dermal fillers and in multi-step regimens.

Who is this for? HA IMMERSE is formulated for anyone with dull, dry, or dehydrated skin seeking immediate smoothing and deeper, sustained hydration. It’s appropriate for sensitive-combination skin types due to its hypoallergenic, non-comedogenic formula and is a practical addition for people who want a lightweight serum that supports skin health alongside professional treatments like fillers. Those aiming to reduce the appearance of fine lines and improve overall radiance will find it particularly useful as part of a consistent daily routine.
