Time fades most scars in terms of colour; but as YOU age and as your skin loses collagen, some scars, might seem to become deeper or more noticeable. If you have a very prominent scar that is highly visible on your face, arms, belly or legs, for example – you might want to investigate your options for minimising them. There are several different types of micro needling products that doctors can use on your skin to fade different scars. Whilst there is some variance in the flexibility of the tools and how they are utilised for skin rejuvenation or scar minimisation, they work on a similar principle: precisely controlled micro-injury to skin tissues to stimulate renewal, collagen restructuring and faster recovery.
What Is Micro-needling?
Micro-needling with a Dermapen carries a low risk of hyper-pigmentation problems and additional scarring, which makes it a suitable treatment choice for people who have sensitive skin, thin skin or skin with a naturally high-melanin content prone to discolouration problems or melasma. Clinical studies have consistently shown micro-needling to improve the appearance of:
- most types of scars
- superficial facial lines or early-stage wrinkles
What is the cause of scarring?
- Injuries, surgery incisions, chicken pox and acne can all leave their mark.
- Wounds, inflammation, injury, burns or infection can all form permanent scars.
microneedling for suture repair
A surgical scar is a type of injury to flesh caused by surgery, usually an incision, that requires the modification of all layers. Because a surgeon cannot control all the factors that determine the appearance of a scar, treatment after the surgical area has properly healed is sometimes necessary. The challenge with surgical scars lie within the matrix of all the forms or categories of scars involving hypertrophic and keloid scars and pigmentation flaws. These scars thicken over time. Scar therapy has been historically limited. The Dermapen’s unique vertical stamping and depth control, up to 2.5mm, helps alleviate the appearance of surgical scars and can be a better modality to other methods or rollering. With surgical steel integrity, the robust nature of the automated needle tip (12 needles total and sized at thirty-three gauge) penetrate difficult scar tissue, dramatically improving appearance, texture, elasticity, size and mobility. Multiple microneedling treatments is recommended and may vary depending on the severity and type of surgical scar. Consult doctor about the best course of action for your particular surgery scars.
Scar treatment caused by burns with Micro-needling
Burn scars can be devastating to quality of life, not only due to appearance deficits but effects on mobility of the affected area and increased sensitivity as well. Various surgical interventions as well as dermatologic therapies such as laser resurfacing, fractional laser, radiofrequency energy, chemical peels, and dermabrasion are all used to deal with surface irregularities and discoloration in an effort to reduce the overall appearance of the scar and blend any lines of demarcation which contribute to visibility. Efficacy of the current array of therapies is mitigated by associated drawbacks. For one thing, ablative damage may simply exacerbate sensitivity, which is undesirable. In some ways the therapy mimics the original pathology responsible for the scarring, and may cause increased fibrosis and erosion of the dermal papillae over time with repeated treatment. Also, the reliance on necrotic damage (via trauma, ablation, or coagulation of tissue) brings with it unwanted possibilities such as overstimulation of the inflammatory cascade. Microneedle percutaneous collagen induction (PCI) therapy for burn scars may represent an excellent modality because the epidermis and surrounding tissue structures are left largely intact after fractional microneedle treatment, and collagen induction occurs in a more natural manner. Cell death due to controlled damage is by apoptosis, a natural process by which the inflammatory cascade is limited and more effectively managed. Wounding via serial fractional microneedle insertion stimulates the natural wound healing and cell replacement responses but heals over rapidly, resulting in a quick restoration of barrier function. As growth factors saturate the area fibroblast production is increased and activity is upregulated, with subsequent proliferation and stimulation of keratinocytes. A natural lattice of healthy collagen is built from the bottom up, which is a key aspect to successful scar revision; the epidermal tissue is spared, which is especially ideal in the case of burn scarring. Notably, microneedle therapy with Dermapen may be used on body locations considered much less suitable for most modalities. The mechanism of action, apoptotic induction of natural collagen lattices, lends itself to repeat treatment with no concern of erosion or other negative modification of treated tissue.
After the treatment of scar with Microneedling
- skin may appear a bit pink to reddish in colour by the 2nd day.
- There may be some swelling as well. This usually subsides by about day 3.
- After day 3 post your dermapen treatment, you can typically return to your normal skincare routine in the days after your microneedling skin treatment.
- You’ll typically see results after just one treatment, however the strongest results show up after several treatments because the skin needs time to go through a cycle of cellular renewal.
