EXO H-SERUM Hyaluronic Acid Treatment

Route: Topical facial application.

Apply a few drops to freshly cleansed, slightly damp skin (applying HA to damp skin optimizes its water-attracting mechanism). Press gently into the skin rather than rubbing. Follow with a moisturizer or occlusive preparation to seal in the hydration. For daytime use, apply sunscreen after moisturizer. Avoid contact with eyes and mucous membranes. Apply as directed by the prescribing clinician.

Application protocol is prescriber-directed. Standard practice:

• Apply once or twice daily (morning and evening) to the full face or targeted areas.
• Application to slightly damp skin enhances humectant efficacy.
• Consistent use over 8–12 weeks is recommended before formal assessment of skin hydration and quality improvements.

• Hyaluronic Acid: HA is an unbranched polysaccharide of repeating N-acetylglucosamine and glucuronic acid disaccharide units; a single gram can hold up to 6 liters of water via hydrogen bonding, making it the most hydrophilic natural polymer in biology. Applied topically, high-molecular-weight HA forms a moisture-retaining film on the skin surface and epidermis, reducing TEWL; lower-molecular-weight HA fragments penetrate more deeply into the epidermis and interact with CD44 and RHAMM receptors on keratinocytes and fibroblasts, modulating cell migration, proliferation, and wound-repair signaling. HA also provides viscoelastic cushioning to the dermis and contributes to the structural support of the ECM.
• Exosome/EV Complex: Extracellular vesicles are internalized by skin cells via endocytosis; their growth factor cargo (TGF-β, VEGF, FGF) activates fibroblast collagen and elastin synthesis; miRNA cargo suppresses inflammatory pathways (NF-κB, IL-6, TNF-α) that accelerate collagen degradation and skin aging. The combination of HA's structural and hydration effects with exosome regenerative signaling provides complementary benefit that addresses both the physical (hydration, plumping) and biological (collagen renewal) dimensions of skin quality.

Clinical Context: EXO H-SERUM is used in prescriber-directed protocols for patients presenting with dehydrated, dull, or chronologically aged skin where loss of dermal HA content is a significant contributing factor. Endogenous HA declines significantly with age (skin HA levels decrease approximately 50% by age 50), leading to reduced dermal turgor and increased fine-line visibility. This serum addresses both the hydration deficit (via exogenous HA) and the regenerative cellular signaling deficit (via exosome complex) that contribute to these changes.

Monitoring Considerations:

• Assess skin hydration metrics (corneometry), TEWL, and visual skin quality at 8–12 weeks.
• Consider the molecular weight profile of the HA in the formulation; multi-molecular-weight HA (high + low MW) provides both surface and deeper epidermal benefits.

Contraindications:

• Known hypersensitivity to hyaluronic acid, any exosome component, or formulation excipients.
• Active facial infection or significantly inflamed skin at the application site.

Warnings & Precautions:

• For topical use only. Avoid ocular contact.
• HA topical preparations are generally extremely well tolerated and non-irritating; hypersensitivity is uncommon.
• In very dry or arid environments, high-molecular-weight HA may theoretically draw moisture from deeper skin layers rather than the atmosphere; application to damp skin and following with a moisturizer/occlusive reduces this risk.

Drug Interactions:

• No established clinically significant drug interactions for topical HA or exosome preparations.

Common Side Effects: Extremely rare. HA is one of the most biocompatible topical ingredients available. Mild temporary stickiness at application. Possible rare contact allergy to formulation excipients.

Store at controlled room temperature (20–25°C / 68–77°F) unless the label specifies refrigeration for the exosome component. Protect from light and heat. Keep tightly capped. Do not freeze. Keep out of reach of children. Use before the BUD assigned by Genesis Compounding.

Why is applying this serum to damp skin recommended?

Hyaluronic acid is a humectant — it attracts water from its surroundings. On damp skin, it draws from the water already on the surface and locks it into the epidermis. On completely dry skin in a dry environment, it may theoretically draw moisture upward from the dermis; applying to damp skin and sealing with a moisturizer prevents this.

What does hyaluronic acid actually do for my skin?

HA is the primary water-binding molecule in your dermis. As skin ages, its HA content declines, leading to reduced turgor, increased visibility of fine lines, and dullness. Topical HA replenishes this hydration layer, temporarily plumping skin and reducing the appearance of dehydration-related fine lines.

What do the exosomes add to this serum?

Hyaluronic acid hydrates and plumps. The exosomes provide a complementary layer — delivering growth factors and miRNAs that stimulate your fibroblasts to produce new collagen and elastin, suppressing inflammatory aging signals. Together, they address skin aging both at the surface hydration level and at the cellular regenerative level.

Is this FDA-approved?

No. This is a prescription-only 503A compounded preparation made by Genesis Compounding. It is not an FDA-approved drug product.

How does this compare to injected hyaluronic acid fillers?

Topical HA works at the skin surface and superficial epidermal layers to improve hydration and skin quality. Injectable HA fillers are placed subdermally to restore volume and structural support in deeper tissue planes. These are distinct applications; your prescriber can advise which is appropriate for your clinical goals.
