Microneedling devices are becoming increasingly popular with recent development in home and professional use. The proliferation of this technology for skin rejuvenation has been primarily driven by the marketing efforts of companies selling the devices. Although there is some scientific support for its use in some areas, there is also many safety concern. In addition, the lack of standardization across different microneedling devices poses risks to patients.
Microneedling is a procedure that involves the use of a handheld electrically powered device to puncture the skin to create thousands of minor wounds, or micro-injuries, on its surface. This process is also known as collagen induction therapy (CIT), controlled injury therapy (CIT), or derma roller therapy. The many different types of microneedling devices differ in the number and length of metal pins rolled over the skin. Some require applying a topical numbing agent; first, others do not. You should be aware of the best microneedling pen for home use to use on your own.
Microneedling Device Benefits
- Increase Collagen Production
The body’s natural repair process responds to tiny cuts on the skin by producing collagen, which is the body’s major protein. As a result, it can lead to more youthful and vibrant skin. Collagen production begins when a derma roller is used at the first few treatment intervals.
- Improve Acne Scars
Acne scars can be a great source of emotional disturbance and low self-esteem, especially for teenagers. Microneedling can help improve acne scars by producing collagen and promoting the body’s natural healing mechanism.
- Improve Signs of Aging
Microneedling can treat signs of aging such as skin laxity, wrinkles, and surface roughness. The procedure is done as a series of treatment sessions at three to eight-week intervals.
- Treat Stretch Marks
Stretch marks are formed when the skin is stretched to its limits due to rapid weight gain or pregnancy. Stretch marks can develop into deep grooves in the skin known as “stretch mark depressions.”
- Treat Sun Damaged Skin
Dry, flaky skin, wrinkles, and loss of elasticity are signs of sun-damaged skin. Microneedling therapy can reduce fine lines, wrinkles, and hyper-pigmentation associated with sun damage.
Risks of Using Microneedling Device
- Risk of Mild Bleeding
Microneedling can result in mild swelling, redness, and fluid discharge. If this occurs, the process can be stopped and bleeding controlled for 24 hours by applying a topical numbing agent.
- Risk of Permanent Wounds
It is vitally important to avoid any secondary injuries to the skin caused by using an overly aggressive device. Overly aggressive treatments may result in severe skin trauma with possible scarring of the skin or tissue.
- Risk of Infection
Infections can occur when the skin is punctured. The risk of disease may be increased by using topical numbing creams that numb the area to be treated and delay feeling any discomfort. In addition, it may make it harder to know if you are using too much pressure on your face and increase the potential for injury. If you experience any signs of infection, you should promptly stop using your derma roller and contact your doctor immediately.
- Risk of Skin Slippage
Using substantial pressure on the skin could cause trauma to the skin, leading to permanent injury or scarring.
- Risk of Granuloma
Overuse of a derma roller can cause a granuloma to form on the skin. A granuloma is a localized collection of inflammatory cells that form in an area after trauma, infection, or a foreign body. The use of dermal rollers has been associated with granulomas since their invention in 1910.
Safety Measures of Using Microneedling Device
- Microneedling aims to produce a superficial wound that heals within one week. To prevent skin damage and injury, use the device in an upright position with even pressure. If a wound is too deep, it may result in a more prominent scar as the healing process continues. This risk can be minimized by using just enough pressure at each treatment session.
- After each treatment, you should apply topical antibiotics and corticosteroids to treat any wounds and help speed up the healing process. It might also be good to use sunscreen lotion during the healing process to prevent discoloration.
- Avoid treating the same area on consecutive days, which can prolong your recovery period.
- If you feel any discomfort or pain during treatment, you should stop using your derma roller immediately and seek medical advice from your doctor.
- It would help if you opted for a device with at least 0.5 mm diameter to treat the critical area. When using a device with more than that, you may have a larger wound.
The main problems with microneedling include the risk of infection, granulomas, and scarring, although some dermatologists are keen to promote its use in targeted areas like the neck or face. Microneedling is not recommended for children unless their mother or doctor is already familiar with this procedure.
