An effective solution for a wide range of skin problems
Microneedling is a minimally invasive dermatological procedure that creates thousands of microchannels of controlled depth in the skin. It has gained widespread popularity for treating various skin conditions. It is used to treat acne scars, wrinkles, hyperpigmentation, stretch marks, as well as for general rejuvenation and improvement of skin condition.
The micro-injuries created during the procedure trigger the body’s natural wound healing processes, releasing growth factors and activating fibroblasts, which are responsible for the production of collagen and elastin. In addition, microneedling improves collagen structure, improving skin texture and elasticity over time.
Microchannels in the epidermis allow for better penetration of topically applied preparations such as serums, exosomes, polynucleotides, vitamins, or growth factors. This improved absorption can significantly increase the efficacy of other therapeutic procedures, making microneedling a valuable addition to various dermatological therapies.
Microneedling is a minimally invasive dermatological procedure that uses fine needles to create controlled microtraumas in the skin. It is extremely effective in treating various skin conditions, including scars, wrinkles, stretch marks, and overall skin rejuvenation.
Understanding the mechanism of action of microneedling involves knowledge of skin anatomy and the biological responses it elicits. The skin consists of three main layers: the epidermis, the dermis, and the subcutaneous tissue. The epidermis acts as a protective barrier, while the dermis contains collagen and elastin fibers that provide structural support and elasticity to the skin. Microneedling creates micro-injuries in the dermis without causing significant damage to the epidermis.
Micro-injuries trigger the body’s natural processes for wound healing, releasing growth factors and activating fibroblasts, which are responsible for the production of collagen and elastin. In addition, microneedling improves collagen structure, improving skin texture and elasticity over time.
In addition to synthesizing new collagen, microneedling stimulates the formation of new blood vessels. This process improves blood supply to the treated area, enhances nutrient delivery, and aids in the healing process. Increased vascularization contributes to healthier and more vibrant skin and improves the healing of scars and other skin lesions.
Another significant advantage of the procedure is its ability to improve transdermal drug delivery. The microchannels in the epidermis allow for better penetration of topically applied preparations such as serums, exosomes, polynucleotides, vitamins, or growth factors. This improved absorption can significantly increase the efficacy of other therapeutic procedures, making microneedling a valuable addition to various dermatological therapies.
Over the past few decades, microneedling has undergone significant development. Various techniques and devices have been developed to improve the effectiveness of the procedure and patient safety.
Handheld microneedling rollers are devices with a roller covered in fine needles. They are designed for home use, making them a popular choice for people who want to improve their skin texture without professional help. Although they can address minor skin issues, the limited depth of the needles often makes them less effective than professional devices.
Automated microneedling devices of the pen type use a motorized mechanism to create thousands of microchannels in the skin, reaching a depth of up to 2.5 mm. This method allows for more precise treatment, effectively targeting scars and stimulating skin remodeling more effectively than manual rollers. Examples include Dermapen4 and Mpen by mesoestetic.
Radiofrequency microneedling combines traditional microneedling with radiofrequency energy to heat the tissues deep within the dermis. This technique stimulates collagen production through thermal damage, improving skin tightening and texture with minimal recovery time. The most popular representatives of this group of devices are Morpheus8, Morpheus8 Burst, and Morpheus8 Body by InMode.
A remarkable development in microneedling is the introduction of devices with adjustable needle depth. This feature allows doctors to tailor procedures to specific skin problems and individual patient needs. It significantly improves results, as different skin problems require different depths of penetration. Such devices include Dermapen4, Mpen, Morpheus8, and its variants.
Microneedling has established itself as an effective solution for a wide range of skin problems by stimulating collagen production and promoting skin rejuvenation. This procedure is particularly effective for treating atrophic acne scars, improving skin texture, and significantly reducing visible scars over time. Comparative studies show that microneedling is more effective than chemical or laser peels for reducing acne scars, with a higher degree of satisfaction and a lower risk of side effects and hyperpigmentation in darker skin types.
Microneedling significantly reduces the appearance of fine lines and wrinkles. The procedure helps tighten the skin and creates a youthful appearance by stimulating collagen and elastin production. In addition to reducing wrinkles, microneedling improves the overall texture and tone of the skin. The procedures stimulate dermal regeneration for smoother skin and a more even complexion.
Microneedling shows promising results in the treatment of hyperpigmentation and melasma by breaking down pigment deposits in the skin. The micro-wounds created during the procedure improve the absorption of topical products. Combining microneedling with vitamin C or retinoids facilitates deeper penetration of these agents, leading to more effective treatment of pigment problems.
Microneedling treats hair loss conditions such as androgenic alopecia. The procedure stimulates the scalp by promoting increased blood flow and the release of growth factors that stimulate hair growth. When combined with growth factors or PRP, microneedling produces significantly better results.
Microneedling is a relatively safe procedure with no lasting side effects or complications, which is essential for both patients and doctors. The most common side effects are mild and subside within a few days. Usually, immediately after the procedure, erythema, or redness of the skin, appears and lasts from several hours to several days. This is a normal reaction to the microtraumas created during treatment. Mild edema or swelling may occur in the treated area, which usually subsides within a few days. Cold compresses can significantly help relieve the discomfort associated with swelling. Another common side effect in people with darker skin is temporary hyperpigmentation, which usually subsides within a few weeks. The use of appropriate sun protection is crucial to dealing with this problem.
The main risks of the procedure are related to improper care or contamination of the skin afterwards. Infections are the most serious potential risk, especially when hygiene and aftercare protocols are not followed. Allergic reactions may also occur, especially when local products or anesthetics are applied during the procedure. Although rare, permanent scars may form in patients with a history of keloid formation.
Choosing a qualified doctor and following post-procedure care instructions are essential for minimizing the risks of microneedling.
Contraindications
Patients with wounds or skin infections in the treatment areas should treat these conditions before the procedure. Individuals with blood disorders, especially those with blood clotting problems or those taking anticoagulants, should avoid microneedling. The effect of the procedure during pregnancy has not been established, so it is recommended that treatment be postponed until after childbirth. Patients with a history of keloid scarring are at increased risk of scarring as a result of the procedure.
Post-procedure care
Effective management of side effects from the procedure is crucial to ensuring maximum patient satisfaction and safety. Cold compresses and nonsteroidal anti-inflammatory drugs can help reduce redness and swelling in cases of erythema and edema. In cases of hyperpigmentation, broad-spectrum sunscreen products and topical agents containing ingredients such as hydroquinone or retinoids can help manage and prevent further pigmentation problems. If signs of infection appear, immediate medical attention is necessary and topical or oral antibiotics may be prescribed. In case of allergic reactions, it is important to discontinue use of all suspected allergens and consult a doctor for appropriate treatment.
Microneedling rollers sold for home use penetrate the skin to a minimal depth and therefore do not reach the dermis, where medical microneedling works. The results achieved are minimal and the procedure carries risks of infection, scarring, pigmentation, or the spread of warts, herpes, and other viral formations on the skin.
First and foremost, the treating physician will ensure your safety; minimize the risks of side effects; personalize the procedure according to your specific needs; and provide you with maximum and long-lasting results.
The results of microneedling appear gradually as your body produces collagen. You may notice improvement within a few weeks. It usually takes several months to see the full results. Some patients need a series of treatments to achieve optimal results.
The duration of the results achieved depends on your age and lifestyle. The younger you are and the healthier your lifestyle, the longer you will enjoy the results of the procedure. As we age, our bodies lose more and more collagen and find it harder to produce new collagen. Harmful habits such as smoking or excessive sun exposure also affect collagen.
Recovery time is minimal. Immediately after the procedure, you may notice redness (on lighter skin) or darker spots (on darker skin) on the treated skin. These reactions usually disappear within a few days to a week. Although you may experience slight discomfort, you can return to work immediately after the procedure.
Apply cold compresses to the treated areas. Your dermatologist will prescribe a mild soothing cream to protect and moisturize your skin.
However, it is important to wait 24 hours before applying makeup.
