  2. Microneedles - Wikipedia

    en.wikipedia.org/wiki/Microneedles

    The invention of MNs have retained the benefits of both hypodermic needles and transdermal patches while minimizing their cons. [12] [26] Compared to hypodermic needles, MNs provide a pain-free administration. [11] [12] MNs are able to penetrate through the epidermis, but not any deeper to compress on nerve-ends to produce pain responses.

  3. Hypertrophic scar - Wikipedia

    en.wikipedia.org/wiki/Hypertrophic_scar

    A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.

  4. Collagen induction therapy - Wikipedia

    en.wikipedia.org/wiki/Collagen_induction_therapy

    Nurse performing collagen induction therapy for scar reduction using a microneedle stamping device [ edit on Wikidata ] Collagen induction therapy ( CIT ), also known as microneedling , dermarolling , or skin needling , is a cosmetic procedure that involves repeatedly puncturing the skin with tiny, sterile needles (microneedling the skin).

  5. Transdermal patch - Wikipedia

    en.wikipedia.org/wiki/Transdermal_patch

    The 100-1000 μm needles spread across the patch, making sure people will not feel any discomfort from the patch. There are two types of needles used in MNPs, the first one is non-water-soluble needles made out of metal, ceramic, or polymer, and the second one is water-soluble needles made out of saccharides or soluble polymers. [6]

  6. Intradermal injection - Wikipedia

    en.wikipedia.org/wiki/Intradermal_injection

    Most intradermic needles require a change in injection technique or instruction to use, for example a perpendicular intradermal injection. [4] Immune reaction tests sometimes use a set of non-hollow needles for scarification, shallowly abrading the skin. The inoculation is limited to the dermis.

  7. Needlestick injury - Wikipedia

    en.wikipedia.org/wiki/Needlestick_injury

    Blunt-tip or tapered-tip suture needles can be used to sew muscle and fascia. Though they are more expensive than sharp-tipped needles, this cost is balanced by the reduction in injuries, which are expensive to treat. [7] [20] [21] Sharp-tipped needles cause 51–77% of surgical needlestick injuries. [22]

    en.wikipedia.org/wiki/Facial_rejuvenation

    Facial rejuvenation is a cosmetic treatment (or series of cosmetic treatments), which aims to restore a youthful appearance to the human face. Facial rejuvenation can be achieved through either surgical and/or non-surgical options. Procedures can vary in invasiveness and depth of treatment.

  9. Silicone gel sheeting - Wikipedia

    en.wikipedia.org/wiki/Silicone_gel_sheeting

    Silicone gel sheeting addresses the 3 requirements well among scar treatments. [5] Several randomized controlled trials were carried out to assess the effectiveness. Silicone gel sheeting produces a statistically significant reduction in scar thickness and color amelioration. Therefore, it is an evidence-based non-invasive preventive treatment ...
