Multi-Depth Hydration and Rejuvenation with HA Serum

Hyaluronic Acid is a cornerstone of modern hydration, but not all HA serums are created equal. OptoDerm’s HA Serum is a sophisticated, multi-molecular formulation that leverages the distinct biological activities of different HA weights to deliver comprehensive hydration and anti-aging benefits throughout the skin. This intelligent formula goes beyond simple surface hydration to actively support barrier function, reduce inflammation, and smooth the appearance of wrinkles.

The Science of Multi-Molecular Weight Hyaluronic Acid

Our HA Serum contains a precisely calibrated blend of three different molecular weights of Hyaluronic Acid, each performing a specific function:

• High Molecular Weight (HMW) HA (1 MDa): This large molecule remains on the skin’s surface, where it forms a breathable, non-occlusive film that draws moisture from the environment. This provides immediate surface hydration, plumps the skin to soften the look of fine lines, and provides a smooth, silky feel.
• Medium Molecular Weight (MMW) HA (55 kDa): This mid-sized molecule penetrates into the upper layers of the epidermis, where it provides deeper, more sustained hydration and reinforces the skin’s natural barrier function.
• Low Molecular Weight (LMW) HA (10 kDa): This small molecule is able to penetrate into the deeper layers of the epidermis and even the dermis. Here, it does more than just hydrate. LMW-HA acts as a signaling molecule, interacting with cell receptors like TLR2 and TLR4 to stimulate the production of beta-defensin 2, an antimicrobial peptide that enhances the skin’s innate immunity. It also upregulates the expression of tight junction proteins, strengthening the skin’s barrier from within and reducing transepidermal water loss (TEWL).

This multi-molecular approach ensures that the skin receives hydration and biological benefits at every level, from the surface to the deeper layers.

Synergistic Active Ingredients for Enhanced Results

To complement the multi-depth hydration of the HA, the serum is fortified with a blend of powerful active ingredients:

• Argireline® (Acetyl Hexapeptide-8): This renowned neuropeptide works by mimicking the N-terminal end of the SNAP-25 protein, competing with it for a position in the SNARE complex. This destabilizes the complex, preventing the release of neurotransmitters that cause muscle contraction. The result is a significant reduction in the depth of expression lines, particularly around the eyes and forehead, providing a topical alternative to more invasive procedures.
• Hydrolysed Collagen: These small collagen peptides act as signaling molecules, stimulating fibroblasts in the dermis to produce more of the skin’s own collagen, elastin, and hyaluronic acid. This helps to improve skin density, firmness, and elasticity from within.
• Kombucha Ferment: A rich source of organic acids, vitamins, and probiotics, Kombucha ferment provides multiple benefits. It has a powerful anti-glycation effect, protecting collagen and elastin from the degradation caused by sugar molecules. It also enhances skin smoothness, radiance, and color for a healthier, more vibrant complexion.
• Xyloglucan: This plant-derived polysaccharide has a structure similar to hyaluronic acid and provides excellent moisturizing and film-forming properties, further enhancing the serum’s hydrating capabilities.

Ideal Applications

HA Serum is a universal serum suitable for all skin types and ages. It is an essential product for anyone seeking to improve hydration, address the signs of aging, and support overall skin health. It is particularly beneficial for dehydrated skin, mature skin with fine lines and wrinkles, and as a complementary treatment to professional procedures such as microneedling or injectables.

Clinical Benefits

With regular use, HA Serum delivers intense, multi-level hydration, leaving the skin feeling plump, supple, and deeply moisturized. The appearance of fine lines and expression wrinkles is visibly reduced. The skin’s barrier function is strengthened, leading to a more resilient and less reactive complexion. The overall texture is smoother, and the skin has a healthy, youthful glow.
