Topical hydrates. Oral supports. Injectable transforms. Understanding HA by delivery.
Hyaluronic acid (HA) is one of the most celebrated ingredients in skincare, renowned for its ability to hydrate, plump, and revitalise the skin. But depending on how it’s delivered—topically, orally, or via injection—HA behaves very differently in the skin.
So, do all forms of HA offer the same effect? Not quite. Here’s how each type works, and why it matters.
1. Topical Hyaluronic Acid
Where it works: Epidermis (surface layers)
Topical HA is found in many serums and moisturisers as a humectant. It draws moisture from the environment or deeper skin layers and holds it at the surface, providing an instant feeling of hydration, a dewy glow and subtle plumpness.
However, this effect is mostly superficial. HA molecules applied topically do not penetrate deeply, and are unable to address structural hydration or long-term skin quality. Hence, most HA skincare offers surface hydration, but they don’t regenerate.
[ Doctor’s Tip: Apply HA skincare on slightly moist skin, followed by a moisturiser to help lock in hydration. ]
Moyem’s Hydra-Intensive Therapy is a game-changer in the field of topical HA. This professional serum has a high concentration of AuHA™ (Gold thioethylamino hyaluronic acid), a patented innovation that combines small HA molecules with gold nanoparticles. Unlike conventional HA serums, these nano-sized complexes are designed to penetrate the epidermis and activate CD44 receptors on keratinocytes effectively. This, in turn, triggers a regenerative cascade deep within the dermis to increase skin’s own production of HA, collagen, and elastin—key components for firmness and elasticity.
Consider the Hydra-Intensive Therapy for:
- Deep-layer skin stimulation without needles: Proven by ultrasound imaging studies to increase collagen and HA production in both the epidermis and dermis
- Skin firmness: Improves skin firmness by up to 171%
- Wrinkle reduction: Up to 56% decrease in wrinkle appearance
- Long-term skin revitalisation alongside immediate hydration
2. Oral Hyaluronic Acid Supplements
Where it works: Systemically
Oral HA is broken down and absorbed as smaller fragments (oligosaccharides) in the gut. When taken consistently (typically 120–240 mg/day), it has been shown to improve skin hydration, elasticity, and even reduce the appearance of fine lines after 4–8 weeks.
[ Doctor’s Tip: While slower in onset, oral HA is a gentle, inside-out approach—especially helpful as an added measure in mature or dry skin, as well as for joint lubrication. ]
3. Injectable HA (Skinboosters)
Where it works: Dermis and sub-dermis
Injectable HA treatments (like Youth Dew skinbooster and Profhilo Hydrolift) deliver hyaluronic acid exactly where it’s needed—into the dermal matrix, where hydration and structural support decline with age.
By replenishing depleted dermal stores, HA Skinboosters improves skin quality, radiance, sensitivity and comfort—a difference you can see and feel.
Unlike traditional fillers that add volume directly through mechanical means, Profhilo Hydrolift works biologically to rejuvenate skin’s underlying structures and restore more youthful facial contours. Patented NAHYCO technology provides sustained release of HA to stimulate fibroblast activity for collagen, elastin and HA regeneration. The increased dose in Profhilo Restructura revitalises adipose-derived stem cells for natural restoration of subcutaneous fat and structural integrity of the skin.
[ Doctor Tip: Injectables remain the gold standard for replenishing lost dermal hydration and provides rejuvenation benefits. ]
Final Thoughts
While all forms of HA support skin health in different ways, they are not interchangeable.
- Topical HA offers immediate, surface hydration. Ideal for milder dehydration and for maintenance after skinboosters.
- Oral HA supports general skin hydration and joint health in more dry skin or mature patients.
- Injectable HA provides the most dramatic deep hydration, targeted rejuvenation and improvement in skin quality.
- Advanced topicals using AuHA™, featured in Moyem’s Hydra-Intensive Therapy facial, offer a powerful non-invasive boost to your skin regeneration routine across wide age groups.
