Microneedlin: How it work

Heeey guys. I’m  back 😏

Estou de volta e a todo vapor com esse assunto que é pra lá de booom.

I’m back at full blast with this article that’s amazing.

O post de hoje é sobre uma materia daquela revista “New Beauty” que já comentei aqui com vocês que gosto muuuuito, lembram?!! Eu achei a matéria bem interessante. O post é todo inglês, mas já estou preparando um em português sobre esse tratamento incrível. Bora conferir essa matéria?!

This post is about a very interesting magazine article, at one of my favorite magazine called “New Beauty”.

Microneedling: How it works

According to Mokena, IL dermatologist Donna Stockton, MD the goal when using any microneedling device, whether at-home or in-office, is to create precise  micro injuries in the epidermis, causing controlled inflammation. “This prompts the release of cytokines- proteins that signal the cells to activate healing – in the body, which leads to the formation of new skin tissue and stronger collagen and elastin,” says Dr.Stockton.Professional microneedling may be best known for its ability to incite new collagen, giving skin on the face, neck, hands and body a firmer look with reduced fine lines and wrinkles.

The treatment is safe for most skin types, although doctors often advice patients with active inflammatory acne, eczema, psoriasis, moderate-to-severe melasma, herpes simplex virus, or a history of keloids to avoid microneedling because the conditions may worsen. It’s also lauded for its propensity to soften rough, sun- damaged skin and reduce enlarged poros, actinic keratosis, cellulite, stretch marks, discoloration, and hyperhosrosis. Perhaps miceoneedling`s biggest coup: erasing deep-pitted boxcar and rolling acne scars, which, for years, only responded to invasive laser and surgical excision. “ The microdamage inflicted upon the epidermis by the needles helps reorganize collagen to improve the scars,” says Kansas City MO dermatologist Audrey Kunin, MD. “General improvement of skin tone and fullness can have an almost immediate effect, whereas it can take a few months before scar and wrinkle reduction can be noticed, “adds Dr. Stockton. Whether an at-home roller or doctor-administered device is used, onde the skin has been microneedled and is “open”, one or several active ingredients, including growth factors, antioxidants, peptides, high- molecular-weight hyaluronic acid, melanocyte suppressants, and platelet- rich plasma (PRP) can be applied, which lets them permeate deeper. Eugene, or plastic surgeon Mark Jewell, MD notes that no scientific data or outcome currently supports the therapeutic or asthetic claims of PRP.

Once skin is “open” the active ingredients in topical products can penetra-te more effectively.


At- home rollers are handheld, studded with tiny,stainless-steel or titanium microneedles and designed to roll over skin picture a jade roller that’s spiky rather than smooth. “For some individuals, they can help improve the appearance of pores and small acne scars, but their main benefit is to enhance deeper penetration of topical products. Their shorter needles make them somewhat less effective than in-office procedures,” says Dr. Kunin. Most skin-care experts agree that a device with needles at least 1.5 millimeters long should be used to obtain optimal results. Over-the-counter dermaroller needles are usually less than 0.15 millimeters, compared to the needles used in professional treatments which can be up to 3 millimeters.

Not all doctors are huge fans of at-home microneedling: there have been reports of injury, such as skin tears, because of the oblique angle at which the needles enter the epidermis. “Many at-home dermarollers have a garden tiller-like effect that has the potencial to leave skin damage,” says Dr. Stockton. “But professional tools are very sharp and precise. The market is saturated with low-quality rollers, and patients should be aware of what they are using” It’s algo best to avoid active ingredients like retinol (especially Retin- A and prescription-strength products) and alphahydroxy acids after dermarolling, as they are too harsh for the skin when it’s inn such a sensitive state and can cause irritations, breakouts and infections. “Additionally,, if the roller is not disposed of after its recommended usage, the needles will not pierce the skin properly, which can cause damage, and ultimately , post-hyperpigmentation,” add Dr. Herschthal.


A more intense treatment that uses larger needles with more depth variability, doctor-administered microneedling pens are electrically powered and are stamped numerous times across the skin or used with a corresponding gel to help them move smoothly. Wexford, PA dermatologist Debra T. Abell, MD says their design features a more compact tip than at-home options, allowing them to better treat smaller areas like the nose and upper lip. Although dermarollers can be used in-office, too, most doctors choose medical-grade alternatives, like SkinPen and MDPen.

Prior to the treatment, a topical numbing cream is applied to minimize and in many cases, eliminate pain. A cooling mask will be applied directly after the treatment, and it’s usually recommended to use hyaluronic acid-based gels and serums, too, to keep the skin moist for the first 24 hours. Sun protection is also important, as is avoiding products with silicone, Retin-A and vitamin C. Dr.Abell says there have been reports of granuloma formation (inflamed tissue masses) in the skin, as well as allergic reactions, rashes and infections, when vitamin C is used during and after the procedure. “I’m not sure it has been studied enough to really understand why this happens, but it’s better to just avoid it after the treatment,”Washigton, D.C. dermatolosti Tina Alster, MD says microneedling typically causes mild skin redness that lasts for a few days, although it may linger for as long as a week. Patients should protect their skin from the sun after a microneedling session, she adds, but they may start wearing makeup as soon as the next day.


I hope you enjoyed!
