Overview
Acne, wrinkles, and fine lines are a few of the common skin problems many people face today. These have made people prioritize skincare solutions that promise to enhance hydration, reduce fine lines, and improve overall skin radiance.
With an ever-growing market of products claiming to deliver transformative results, it can be challenging to identify which ones truly stand out.
Some of the most sought-after skincare products are the ones with hyaluronic acid as part of their ingredients. This is because hyaluronic acid helps to maintain skin hydration, plumpness, and elasticity over time.
It’s not surprising to see that HA IMMERSE Serum™ by Alastin Skincare has gained more attention recently. And this is because of its promise to help the skin naturally produce more hyaluronic acid over time.
But does HA IMMERSE Serum™ really work as it claims? Let’s find out.
In this review, we’ll look at the features, benefits, ingredients, and customer feedback for HA IMMERSE Serum™.
So, keep reading to determine whether this serum is worth adding to your skincare routine.
What is HA IMMERSE Serum™?
HA IMMERSE Serum™ is a lightweight, hydrating serum that claims to improve skin hydration at the surface while boosting the skin’s ability to naturally produce hyaluronic acid over time. This serum is designed for individuals seeking smoother, plumper, and more radiant-looking skin.
The product claims to deliver both immediate and long-term benefits. According to ALASTIN Skincare, HA IMMERSE Serum™ includes proprietary ingredients, such as Octapeptide-45, to stimulate hyaluronic acid production deep within the skin. It claims all these will help minimize the appearance of fine lines and wrinkles and hydrate the skin.
HA IMMERSE Serum™ is marketed as non-comedogenic (does not clog pores) and hypoallergenic (reduces the risk of allergic reactions), which makes it suitable for daily use.
But are all these claims true? The remaining sections of this review will shed more light on this.

About the Brand
HA IMMERSE Serum™ is manufactured by ALASTIN Skincare®. ALASTIN Skincare® is a company that claims to specialize in clinically tested, dermatologist-driven skincare products.
ALASTIN was founded in 2015 and has gained attention for its innovative use of peptides and botanicals. The brand is based in the USA and markets its products as hypoallergenic and non-comedogenic. This makes them suitable for a wider audience.
However, ALASTIN’s products are primarily available online, which may limit accessibility. And they are insanely expensive.
How Does HA IMMERSE Serum™ Work?
HA IMMERSE Serum™ works by providing instant hydration to the skin’s surface while helping stimulate the skin’s natural production of hyaluronic acid. One very effective product we reviewed (Beverly Hills MD Multi Hyaluronic Acid Plumping Booster) contains multiple forms of hyaluronic acid and also boosts the skin’s natural production of hyaluronic acid.
Its proprietary ingredient, Octapeptide-45, is intended to plump the skin from within while supporting anti-aging and reducing wrinkles.
Another key ingredient is Silver Mushroom (Tremella fuciformis), which is believed to enhance hydration due to its high water-retention capacity.
HA IMMERSE Serum™ also includes Hexapeptide-11, which blocks the enzymes that break down hyaluronic acid in the skin.
While these ingredients might seem promising, results will likely vary based on individual skin types and usage consistency.
HA IMMERSE Serum™ Ingredients – Are They Safe & Effective?
Octapeptide-45
Octapeptide-45 is a proprietary ingredient in HA IMMERSE Serum™, claimed to stimulate the production of high-molecular-weight hyaluronic acid by activating the HAS2 enzyme in fibroblasts.
According to a study in the Journal of Cosmetic Dermatology, peptides can help to enhance the skin’s hydration levels and promote plumpness. This may reduce the appearance of fine lines and wrinkles.
Silver Mushroom (Tremella fuciformis)
Silver Mushroom is a natural polysaccharide that studies have shown to protect the skin barrier. This extract may also play a role in preventing the skin from aging too quickly, helping the skin heal wounds, and protecting the skin from light. However, more research and clinical studies are required to verify all these uses.
Hexapeptide-11
Hexapeptide-11 is included in HA IMMERSE Serum™ for its role in inhibiting enzymes that break down hyaluronic acid in the skin. This ingredient aims to support long-term hydration and anti-aging benefits by preserving the skin’s natural hyaluronic acid.
Research published in Redox Biology discusses the use of peptides to maintain skin structure and moisture. This suggests that Hexapeptide-11 may have a positive impact on skin health when used consistently.
Aimilia D Sklirou (a researcher in the Department of Cell Biology and Biophysics, Faculty of Biology, University of Athens) and his co-researchers say, in their report, Our presented findings indicate that Hexapeptide-11 is a promising anti-aging agent.
How to Use HA IMMERSE Serum™
Here’s the appropriate way to use HA IMMERSE Serum™:
- Start with 1–2 pumps of the serum.
- Apply to clean, dry skin on the face and neck as the first step in your skincare routine, morning and evening.

Some customers found the product effective. For instance,

Another reviewer who chose to remain anonymous says, It’s hydrating. HA immerse serum seems fine, but not sure if I see a difference in my skin. I’ve been using it for quite a few months on my mature skin. On the positive side, it absorbs in the skin and doesn’t flake like some other skin products I’ve tried.
These reviews highlight varying results, with some users praising its effectiveness while others found limited or inconsistent benefits.
HA IMMERSE Serum™ Review – Conclusion
HA IMMERSE Serum™ claims to deliver instant hydration and long-term anti-aging benefits by enhancing the skin’s natural production of hyaluronic acid. Its lightweight, non-comedogenic formula and dermatologist-tested ingredients make it appealing to those seeking advanced hydration solutions.
However, customer reviews reveal mixed opinions. While some users report improved skin texture and hydration, others express concerns about the inconsistent results of the product. Also, the price of the serum is relatively high and may not suit everyone’s budget. And the need for continuous use to maintain benefits might not suit everyone.
While HA IMMERSE Serum™ may help certain skin types, its variable effectiveness suggests it might not meet everyone’s expectations. So, you may need to consider other hyaluronic acid serums that are more affordable long-term and work effectively.
Hyaluronic acid could be what you need to complete your anti-aging regimen. The hydration that this substance provides can really soften and moisturize your skin, smooth out wrinkles and fine lines and make your skin look radiant and young.
