Unveiling the Marvels of Microneedling: A Journey to Revitalized Skin

Dr. Rana Hashemi & D. M from MedJuvenis

The skin, is a complex tapestry of layers, comprising the epidermis (outer layer) and the dermis (beneath the epidermis), with the subcutaneous layer serving as its base. The dermis functions as a support system for the epidermis. Skin elasticity owes its existence to elastin, which gradually diminishes with age, followed by a reduction in collagen. This leads to the deterioration of the epidermal foundation, resulting in fragile, wrinkled, and sagging skin.
In the process of microneedling, numerous extremely fine and sharp needles penetrate the dermis at an appropriate depth without causing harm to the epidermis, with a consistent penetration rate of approximately 4000 to 6000 times per minute. This action prompts collagen and elastin to initiate the process of repair and regeneration, leading to firmer skin and the reduction of surface wrinkles, visible about three weeks after the procedure. Local anesthesia is administered to ensure a pain-free experience for the patient.
During the needle penetration, depending on the skin type and treatment objective, nourishing substances such as vitamins, hyaluronic acid, exfoliants, and more can be delivered to the dermal layer, all contributing to skin rejuvenation.
Microneedling can be performed once a month for three months initially, followed by maintenance sessions every six months. Its indications include skin rejuvenation, the reduction of fine wrinkles, treatment of deep scars like acne scars, sun-induced pigmentation, and reduction of skin laxity.
Prior to microneedling, certain precautions are necessary, such as abstaining from the use of brightening creams containing hydroquinone and exfoliants 72 hours before the procedure. Avoiding the use of tanning beds is essential, and the application of sunscreen is mandatory.
Post-microneedling care involves a rapid healing process. It is recommended to stay at home on the day of the procedure, cleanse the face regularly with cold water, and apply colorless sunscreen every two hours for the next 48 hours. Additionally, 45 minutes before going outside, use a layer of sunscreen with an SPF of 30 or higher, and reapply every three hours when outdoors. Utilize moisturizing and repairing creams at night and, if experiencing brief pain and burning, consider taking acetaminophen. Incorporate fresh vegetables, fruits, and vitamin C into your diet for optimal results.
