Drug delivery systems (DDS) in aesthetic medicine represent a technological leap beyond traditional topical application. By controlling how, where and when active ingredients reach target tissues, DDS significantly enhance treatment efficacy.
Why Delivery Matters
The skin’s barrier function — particularly the stratum corneum — limits penetration of most active ingredients to less than 1% of the applied dose. Drug delivery systems overcome this barrier through various technologies, increasing bioavailability by 10 to 100 times.
Key Drug Delivery Technologies
Liposomal Encapsulation
Liposomes are spherical vesicles (50-500 nm) composed of phospholipid bilayers. They encapsulate both hydrophilic and lipophilic actives, protecting them from degradation and enhancing skin penetration. Liposomal vitamin C, retinol and peptides show 3 to 5 times greater skin absorption than their free forms.
Nanoparticle Systems
Solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) provide controlled release of actives over 12-24 hours. They are particularly effective for fat-soluble actives such as retinoids and vitamin E.
Transdermal Patches and Microneedles
Dissolving microneedle patches create temporary channels through the stratum corneum, delivering actives directly to the viable epidermis. This technology enables painless delivery of peptides, growth factors and hyaluronic acid.
Hydrogels
Cross-linked hydrogels provide sustained release of water-soluble actives. They maintain hydration while delivering actives over extended periods, making them ideal for post-procedure recovery.
Clinical Applications
Professional DDS products enhance results in anti-ageing treatments, acne management, hyperpigmentation correction, scar improvement and post-procedure recovery. Skymedic's drug delivery serums combine several DDS technologies for maximum clinical efficacy.

Frequently asked questions
What are drug delivery systems in skincare?
They are technologies — liposomes, nanoparticles, microneedling and transdermal carriers — that help actives penetrate deeper and work more effectively than in a conventional topical.
Why does delivery matter as much as the active?
An active only works if it reaches its target in the skin. A good delivery system improves penetration, stability and results, which is why professional formulations invest in it.
Is microneedling a drug delivery method?
Yes: microneedling creates temporary micro-channels that greatly improve absorption of compatible actives, which is why it is often combined with serums such as exosome or PDRN serums.
