The derma roller is a handheld device with a roller head containing hundreds of tiny needles, usually
ranging from 0.25mm to 2.5mm in length.
Derma Rollers work through a process called micro-needling, also known as percutaneous collagen
induction (PCI).
When rolled across the skin, these needles create numerous controlled, microscopic punctures in the
stratum corneum (outermost epidermis layer) and the papillary(upper) dermis.
These micro-injuries lead to minimal superficial bleeding and create a wound-healing cascade by
releasing various growth factors.
The needles also break down the old, hardened scar strands and allow it to revascularize.
Collagen and elastin are proteins that provide the skin with structure, plumpness, and elasticity. As we
age, the production of these proteins naturally declines.
Microneedling stimulates the fibroblasts, the skin cells responsible for collagen and elastin production.
This increased production helps to improve a wide range of indications, including acne scars, post
traumatic/burn scars, alopecia, stretch marks, hyperhidrosis, skin rejuvenation, and many more.
The microchannels created by the derma roller can temporarily increase the skin's permeability.
This allows for better absorption of topical skincare products applied after micro-needling, potentially
enhancing their effectiveness. Recent studies have shown the benefits of using derma rollers for
transdermal drug delivery
