Microneedling, also known as collagen induction therapy, has garnered significant attention in the realm of aesthetic medicine. It's a minimally invasive procedure that uses fine needles to create controlled micro-injuries in the skin, promoting the body's natural healing processes and thus leading to the production of collagen and elastin. This treatment can address a variety of skin concerns, including fine lines, wrinkles, acne scars, hyperpigmentation and overall skin texture. Today I will be breaking down to you the science behind microneedling.
THE SCIENCE BEHIND MICRONEEDLING
Microneedling works by creating multiple tiny punctures in the skin, which triggers the body's wound healing process. This process involves three key phases:
Inflammation Phase : Right after the micro-injuries occur, the body responds by increasing blood flow to the area, which brings growth factors and nutrients to the site of injury. This phase is characterized by redness and mild swelling.
Proliferation Phase : In this phase, new tissue formation occurs. Fibroblasts which are the cells responsible for collagen production are activated and new collagen and elastin fibers are laid down. This helps to strengthen and improve the elasticity of the skin.
Remodeling Phase : Over the next few months, the newly formed collagen matures and reorganizes, leading to a smoother and more even skin texture.
BENEFITS OF MICRONEEDLING
Microneedling offers a range of benefits for various skin types and concerns:
Reduction of fine lines and wrinkles: By stimulating collagen production, microneedling can help reduce the appearance of fine lines and wrinkles, giving the skin a more youthful appearance.
Improvement in skin texture and tone: The controlled injuries encourage the turnover of skin cells, resulting in a smoother texture and more even skin tone.
Reduction of scars: Microneedling is particularly effective for acne scars and other types of scarring. The new collagen and elastin fibers help to fill in and smooth out scar tissue.
Enhanced absorption of topical products: The micro-channels created by the needles allow for better penetration of topical treatments such as serums and skin boosters thus enhancing their efficacy.
Minimally invasive with minimal downtime: Compared to more invasive procedures, microneedling has minimal downtime making it a convenient option for many patients.
THE MICRONEEDLING PROCEDURE
After the face is cleansed, a topical numbing cream is applied to the treatment area to minimize discomfort. A microneedling device, which is a pen-like device with a disposable needle cartridge is passed across the skin, creating controlled micro-injuries. The depth of the needles can be adjusted based on the area being treated and the specific skin concerns. Products containing ingredients such as hyaluronic acid, peptides, amino acids, vitamins or growth factors are applied to the skin during the procedure. These products are absorbed more effectively due to the micro-channels created during the treatment. A soothing mask may be applied to calm the skin following treatment.
AFTERCARE
Proper aftercare is crucial to achieve optimal results and minimize potential side effects. Here are some key aftercare tips:
Avoid Sun Exposure: The skin will be more sensitive to UV rays after microneedling. It is essential to minimize direct sun exposure and use a broad-spectrum sunscreen during daytime.
Hydration: Keep the skin well-hydrated by using a hydrating serum or moisturizer. Drinking plenty of water also helps in the healing process.
Follow-Up Treatments: Depending on the skin concerns being addressed, a few sessions may be necessary to achieve the best results.
POTENTIAL SIDE EFFECTS
There is little to no downtime associated with microneedling. Some potential side effects include mild redness and swelling immediately after the procedure which will typically subside within a few days. Some patients may experience mild bruising, especially if deeper needle depths are used.
Here at Dream Clinic, this procedure is carried out by trained aesthetic doctors thus minimizing the risk of complications.
CONCLUSION
Microneedling has become a popular and effective treatment in aesthetic medicine for addressing various skin concerns, from fine lines and wrinkles to acne scars and overall skin texture improvement. Its ability to stimulate collagen production and enhance the absorption of topical products makes it a versatile option for patients seeking minimally invasive skin rejuvenation.
