Microneedling is a dermatologic procedure that involves small pricks to the skin to generate new collagen production. The result is smoother, brighter, firmer skin. Many people have experienced the benefits of microneedling in improving aging skin, acne, and scars. Microneedling is becoming increasingly popular, because the treatment is minimally invasive and requires no downtime.
As people age, production of collagen tends to slow down. This decrease in collagen can result in skin that wrinkle, sags, and shows age spots or sun spots. Microneedling is an effective treatment for reversing effects of aging and reducing wrinkles. In fact, microneedling is also used in other anti-aging procedures, including eyelid surgery and treatment of sun spots.
Dermatologists have been using forms of microneedling for over 20 years. As technology improves, microneedling techniques are becoming more and more effective. Microneedling can be used on almost on all skin types and tones, as long as the person does not have any open lesions, infections, or trouble with wound healing.
Microneedling can improve the appearance of acne scars and can help reduce acne. Microneedling is one of the most effective, simplest treatments for reducing acne. Microneedling results in smoother skin, a reduction in skin imperfections, and better skin hydration.
However, if someone has active acne or cystic acne, the dermatologist will avoid microneedling over those areas. Microneedling over active acne can irritate acne further, make skin inflamed, and possibly spread bacteria.
The concept may seem counter intuitive that pricking the skin can help reduce scars. But the science behind microneedling is that the body responds to these slight pricks by generating new collagen-rich tissue that is smoother and more even.
Microneedling can be used for scars on the face or even on other parts of the body. One study even found that, combined with derma fillers, microneedling was effective for reducing stretch marks on the thighs and abdomen.
A dermatologist can best assess and advise on the benefits of microneedling for each individual. Typically, people will need 4-6 sessions to see full benefits of microneedling. After a microneedling session, people may notice slight skin irritation and redness for a few days while the skin heals. While skin is healing, wearing sunscreen is crucial. Typically, people see improvement in aging skin, acne, and scars in less than two weeks following a microneedling treatment.
