What Is Biorevitalisation?
Biorevitalisation refers to a group of injectable and topical treatments designed to restore biological skin function not just aesthetics. Unlike volumising fillers, these treatments work at a cellular level to improve hydration, stimulate collagen production, and reactivate the skin's own regenerative processes.
Hyaluronic Acid in Biorevitalisation
Hyaluronic Acid (HA) is a glycosaminoglycan naturally present in the dermis that plays a central role in hydration and structural support. In biorevitalisation:- Binds water molecules at a ratio of up to 1000:1, delivering deep, sustained hydration
- Restores dermal volume and elasticity
- Provides an immediate plumping effect visible after a single session
- Stimulates fibroblast activity, indirectly promoting collagen synthesis
- Effect is primarily physical: hydration, turgor, and structural restoration
HA biorevitalisation is particularly effective for dehydrated, dull skin, early ageing signs, and as a maintenance protocol.
Polynucleotides in Biorevitalisation
Polynucleotides (PDRN Polydeoxyribonucleotides) are DNA fragments derived from salmon sperm that trigger biological repair mechanisms:
- Activate ADORA2A receptors, stimulating fibroblast proliferation and collagen production
- Enhance wound healing and tissue regeneration
- Exert significant anti-inflammatory effects
- Improve microcirculation and oxygenation of tissues
- Effect is primarily biological: stimulating the skin's own regenerative machinery
PDRN protocols produce results that develop progressively over weeks as new collagen is synthesised, with long-lasting improvements in skin quality and texture.
When to Use HA, When to Use PDRN, and When to Combine
Use Hyaluronic Acid when:
- The primary concern is skin dehydration and dullness
- A fast, visible result is needed before an event or season
- Treating younger skin with good baseline regenerative capacity
- Addressing signs of photoageing, skin laxity, or damaged skin texture
- Post-acne or scarring where tissue regeneration is required
- Treating patients where inflammation plays a key role
- Seeking immediate hydration + progressive regeneration in a single protocol
- Treating moderate-to-severe photoageing
- Optimising results over a series of treatment sessions
md:ceuticals Solutions for Biorevitalisation
md:complex GenX Exosomes & PolynucleotidesRegen combines the regenerative power of polynucleotides with exosomes, stem cells, growth factors and hyaluronic acid for a comprehensive biological regeneration protocol.
md:complex NCT Hyal Revitalizing provides deep, multi-level hyaluronic acid hydration to restore dermal water content and skin elasticity.
These two formulations can be used in alternating or combined protocols depending on patient profile and treatment goals.
Final Thoughts
Polynucleotides and Hyaluronic Acid are not competing treatments they are complementary tools in the professional's biorevitalisation toolkit. Understanding their distinct mechanisms allows for the design of truly personalised protocols that address both immediate needs and long-term skin regeneration. At md:ceuticals, both are available in advanced formulations backed by clinical science.
